INTRODUCTION

In this annual report on Form 20-F (the “Annual Report on Form 20-F” or the “Annual Report”), except where the context otherwise requires or where otherwise indicated, the terms “Guardian,” the “Company,” “we,” “us,” “our company” and “our business” refer to Guardian Metal Resources PLC, a public limited company incorporated under the laws of England and Wales, together with its consolidated subsidiaries as a consolidated entity. The term “ordinary shares” refers to ordinary shares of Guardian, each with a nominal value of £0.01 per share, and the term “ADSs” refers to Guardian’s American Depositary Shares (“ADSs”), each of which represents five (5) ordinary shares.

Pursuant to Rule 12b-23(a) of the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”), certain information required to be included in this Annual Report on Form 20-F is being incorporated by reference from the Company’s statutory annual report for the year ended June 30, 2026, including the consolidated financial statements (the “Consolidated Financial Statements”) of the Company included therein (the “Annual Report 2026”), as specified in this Annual Report on Form 20-F. In addition, certain information included in this Annual Report on Form 20-F is incorporated by reference from the Company’s registration statement on Form F-1 (File No. 333-295580) filed with the SEC on May 6, 2026 (the “Form F-1”), as specified in this Annual Report on Form 20-F (see Item 19.B). Therefore, the information in this Annual Report on Form 20-F should be read in conjunction with the Annual Report 2026 and the Form F-1, to the extent specified (see Exhibits 15.1 and 15.2, respectively). With the exception of the items and pages so specified, the Annual Report 2026 and the Form F-1 are not, and shall not be deemed to be, filed as part of this Annual Report on Form 20-F.

The terms “USD,” “U.S. dollars” and “$” refer to the currency of the United States; the terms “GBP” and “£” refer to pounds sterling. The Company publishes its financial statements in USD.

Forward-looking statements

The information set forth in this Annual Report on Form 20-F contains “forward-looking statements” as that term is defined in the U.S. Private Securities Litigation Reform Act of 1995. In some cases, you can identify forward-looking statements by the following words: “may,” “might,” “will,” “could,” “would,” “should,” “expect,” “plan,” “anticipate,” “intend,” “seek,” “believe,” “estimate,” “predict,” “potential,” “continue,” “contemplate,” “aim,” “possible” or the negative of these terms or other comparable terminology, although not all forward-looking statements contain these words. These statements involve risks, uncertainties and other factors that may cause our actual results, levels of activity, performance or achievements to be materially different from the information expressed or implied by these forward-looking statements. Although we believe that we have a reasonable basis for each forward-looking statement contained in this Annual Report on Form 20-F, we caution you that these statements are based on a combination of facts and factors currently known by us and our projections of the future, about which we cannot be certain. Forward-looking statements in this Annual Report on Form 20-F include, but are not limited to, statements about:

You should refer to Item 3.D of this Annual Report on Form 20-F for a discussion of other important factors that may cause our actual results to differ materially from those expressed or implied by our forward-looking statements. As a result of these factors, we cannot assure you that the forward-looking statements in this Annual Report on Form 20-F will prove to be accurate.

In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this Annual Report on Form 20-F, and although we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted a thorough inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain, and investors are cautioned not to unduly rely upon these statements. Furthermore, if our forward-looking statements prove to be inaccurate, the inaccuracy may be material. In light of the significant uncertainties in these forward-looking statements, you should not regard these statements as a representation or warranty by us or any other person that we will achieve our objectives and plans in any specified time frame, or at all. We undertake no obligation to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.

Enforceability of civil liabilities

We are incorporated and currently existing under the laws of England and Wales. In addition, certain of our directors and officers reside outside the United States, and most of the assets of our non-U.S. subsidiaries are located outside the United States. As a result, it may be difficult for investors to effect service of process on us or those persons in the United States or to enforce in the United States judgments obtained in United States courts against us or those persons based on the civil liability or other provisions of the United States securities laws or other laws. In addition, uncertainty exists as to whether the courts of England and Wales would:

Table of Contents

There is currently no treaty between (i) the United States and (ii) England and Wales providing for reciprocal recognition and enforcement of judgments of United States courts in civil and commercial matters (although the United States and the United Kingdom are both parties to the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards) and that a final judgment for the payment of money rendered by any general or state court in the United States based on civil liability, whether or not predicated solely upon the United States securities laws, would not be automatically enforceable in England and Wales. We have also been advised by Haynes and Boone CDG LLP that any final and conclusive monetary judgment for a definite sum obtained against us in United States courts with competent jurisdiction would be treated by the courts of England and Wales as a cause of action in itself and sued upon as a debt at common law so that no retrial of the issues would be necessary, provided that:

Whether these requirements are met in respect of a judgment based upon the civil liability provisions of the United States securities laws, including whether the award of monetary damages under such laws would constitute a penalty, is an issue for the court making such decision.

Subject to the foregoing, by obtaining a judgment from the courts in England and Wales, investors may be able to enforce in England and Wales judgments in civil and commercial matters that have been obtained from U.S. federal or state courts. Nevertheless, we cannot assure you that any such judgment obtained from U.S. federal or state courts will be so recognized or enforceable in England and Wales.

If an English court gives judgment for the sum payable under a U.S. judgment, the English judgment will be enforceable by methods generally available for this purpose. In addition, it may not be possible to obtain an English judgment or to enforce that judgment if the judgment debtor is or becomes subject to any insolvency or similar proceedings, or if the judgment debtor has any setoff or counterclaim against the judgment creditor. Also note that, in any enforcement proceedings, the judgment debtor may raise any counterclaim that could have been brought if the action had been originally brought in England unless the subject of the counterclaim was in issue and denied in the U.S. proceedings.

Cautionary note regarding presentation of mineral resource and mineral reserve estimates

This Annual Report on Form 20-F refers to estimated mineral resources, including indicated and inferred mineral resources, and to estimated mineral reserves, including probable mineral reserves. See “—Certain Definitions” for the definition of those terms.

The mineral resource and mineral reserve estimates included in this Annual Report on Form 20-F have been prepared in accordance with Subpart 1300 of Regulation S-K (“S-K 1300”). Under S-K 1300, mineral resources are estimated by a qualified person based on geological evidence, sampling and testing and reasonable prospects of economic extraction, but mineral resources are not mineral reserves and do not have demonstrated economic viability. Mineral reserves are estimated by a qualified person by applying modifying factors to indicated and, where applicable, measured mineral resources that, in the opinion of the qualified person, can be the basis of an economically viable project. We have declared probable mineral reserves only at our Pilot Mountain project; no proven mineral reserves have been declared.

Inferred mineral resources are subject to uncertainty as to their existence and as to their economic and legal feasibility. The level of geological uncertainty associated with an inferred mineral resource is too high to apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful for evaluation of economic viability. Because an inferred mineral resource has the lowest level of geological confidence of all mineral resources, which prevents the application of the modifying factors in a manner useful for evaluation of economic viability, an inferred mineral resource may not be considered when assessing the economic viability of a mining project and may not be converted to a mineral reserve.

Our mineral resource estimates may be materially affected by geology, environmental, permitting, legal, title, taxation, sociopolitical, marketing or other relevant factors. In addition, inferred mineral resources have the lowest level of geological confidence, which prevents the application of the modifying factors in a manner useful for evaluation of economic viability; they may not be considered when assessing the economic viability of a mining project and may not be converted to a mineral reserve.

Unless the context otherwise requires, all references in this Annual Report on Form 20-F to “qualified person(s)” are to a qualified person as defined in S-K 1300. Our disclosure relating to mineral resources and mineral reserves is supported by a technical report summary prepared by qualified persons in accordance with S-K 1300. The technical report summary for the Pilot Mountain project has been filed as Exhibit 96.1 to this Annual Report on Form 20-F.

Set out below is a summary of certain risk factors which could affect Guardian’s future results and may cause them to differ from expected results materially. The factors discussed below should not be regarded as a complete and comprehensive statement of all potential risks and uncertainties that Guardian’s business faces.

Risks Relating to Our Business and Industry

We have no history of mineral production and may never engage in mineral production.

We currently have no operating mines, nor do we have any interest in any mining operations. All of our mineral projects are at the exploration stage, other than Pilot Mountain which is at the development stage, and have never been mined by us, nor have we produced any revenue from mining operations. We also have no applicable operating history upon which to base estimates of future operating costs, capital spending requirements, site remediation costs or asset retirement obligations. Our company has no experience in developing or operating a mine. We may never be able to develop and produce minerals from a commercially viable ore body or mine.

Mineral exploration activities are highly speculative, have a high risk of failure, and may never result in finding ore bodies sufficient to develop a producing mine.

While mineral exploration is necessary to identify potential mineralization, very few mineral properties that are explored are ultimately developed into producing mines. Major expenses will be required to locate and establish mineral reserves, to develop metallurgical processes and to construct mining and processing facilities at a particular site. Most exploration projects do not result in the discovery of commercially mineable ore deposits, and anticipated levels of recovery of mineral resources and mineral reserves, if any, may not be realized, nor may any identified mineral deposit ever qualify as a commercially mineable (or viable) ore body that can be legally and economically exploited. Our exploration programs and activities may not result in the discovery, development or production of a commercially viable ore body or mine.

It is impossible to ensure that the exploration or development programs we plan will result in a profitable commercial mining operation. Estimates of mineral reserves, mineral resources, mineral deposits and production costs can be affected by environmental permitting regulations and requirements, weather, environmental factors, unforeseen technical difficulties, the metallurgy of the mineralization forming the mineral deposit, unusual or unexpected geological formations and work interruptions. The exact effect of these factors cannot be accurately predicted, but the combination of these factors may result in us not receiving an adequate return on invested capital.

Our business is and will be subject to market fluctuations, including fluctuations in tungsten prices.

Our business strategy is directly linked to commodity prices. In the future, our revenues are expected to be derived from the sale of tungsten concentrate (WO₃). Similar to other commodities, tungsten markets are cyclical and may be volatile.

The Company may enter into forward sales or other market strategies to mitigate its exposure to the tungsten market once it commences production. It is not the Company’s current intention to enter into forward or hedging contracts well in advance of potential production. Currently, the Company intends to maintain significant exposure to the tungsten market, and a more formal policy may be implemented if development and construction financing is considered.

Our future sales, if unhedged, would be denominated in U.S. dollars per metric tonne unit (“MTU”) of WO₃ concentrate. Changes in the average price of one (1) MTU of APT, as quoted on the Fastmarkets, would be expected to impact our potential revenue per MTU of WO₃ concentrate. The pre-feasibility study for the Pilot Mountain project, the results of which were announced on June 30, 2026 (the “PFS”), assesses, among other cost and revenue factors, sensitivity to the tungsten price and other metals in the deposit, such as silver and zinc, and the estimated economic outcomes of the PFS are highly sensitive to the tungsten price assumptions used therein.

Tungsten prices fluctuate and are affected by many factors, including demand from industrial sectors such as defense, aerospace and energy, international economic and political trends, including the nationalization of critical minerals, expectations of inflation, expectations of economic activity, the exchange rate of the U.S. dollar to other major currencies, political and economic conditions including international trade disputes and the imposition of tariffs, interest rates, global or regional consumption and demand patterns, speculative activities and increased production due to improved mining and production methods, production costs in major tungsten-producing regions, speculative positions taken by investors or traders in tungsten, wars and other conflicts, changes in supply and changing investor or consumer sentiment (including in connection with the transition to a low-carbon economy, investor interest in cryptocurrencies and other investment alternatives) as well as competition from alternative materials, all of which are beyond our control.

In addition, our operating costs may be affected by general inflationary pressures and increases in the cost or availability of key inputs such as energy, electricity and fuel supply, water supply and access, labor, consumables, critical raw materials, reagents, transportation and equipment. Disruptions in global or regional supply chains, shortages of equipment, spare parts or raw materials, or interruptions in the supply of utilities could delay our operations or materially increase costs. Because a portion of our expenditures is denominated in foreign currencies, exchange rate volatility could also amplify these cost impacts.

Tungsten prices may also be negatively affected by any slowing of the global economy, increases in exports from single market economy countries, notably China, unfavorable shifts in tungsten demand in key markets such as Asia, Europe and North America, and the release of tungsten concentrate into the market from the U.S. National Defense Stockpile. Conversely, supply-side constraints may exert upward pressure on prices. On February 4, 2025, China implemented export restrictions on certain tungsten products, which have continued to tighten global supply and support higher prices. These restrictions, together with heightened U.S. policy focusing on critical-minerals security, have continued to increase volatility in tungsten pricing.

The aggregate effect of these factors is impossible to predict. If tungsten prices fall below our anticipated all-in sustaining costs per MTU for one or more of our projects, including the Pilot Mountain and Tempiute tungsten projects, as well as any other tungsten exploration or development properties we may acquire or advance in the future, we may experience losses and be required to curtail or suspend some or all exploration and development activities. A prolonged decline in tungsten prices could adversely affect our ability to potentially generate positive cash flow from future operations.

Our mineral resource and mineral reserve estimates for Pilot Mountain are based on an assumed WO₃ price of $115,000 per tonne, which is used by the qualified persons in establishing reasonable prospects of economic extraction and in pit optimization under Subpart 1300 of Regulation S-K, and the economic analysis in the PFS assumes a base case price of $197,300 per tonne of WO₃ (on an APT basis, representing a 35% discount to the spot price of approximately $304,000 per tonne as of June 12, 2026). The value of tungsten concentrate is estimated by applying a factor to the APT price, and this factor may vary depending on market conditions and other factors. If APT prices decline materially below the level used in the resource estimate, or if the factor applied to derive concentrate value changes unfavorably, the estimated mineral resources and any future project evaluations may be adversely affected. Increased price volatility could also impact the timing, scope or economic attractiveness of further project activities.

Mining is a capital-intensive industry, and we may be unable to obtain the funding required to advance our projects.

Tungsten exploration, development and mining require substantial amounts of capital to identify and delineate mineral resources and reserves, undertake geological mapping and drilling, conduct metallurgical testing, construct and maintain mining and processing infrastructure, comply with regulatory requirements, and meet ongoing operational needs. As our projects advance, we expect capital needs to increase materially in connection with permitting activities, development work, construction of processing facilities and any future production operations.

Our future capital expenditure requirements will depend on many factors, including the results of exploration programs, updates to the technical report summary for the Pilot Mountain project, changes to mine plans, the cost and availability of equipment, labor and contractors, and broader market conditions such as interest rates and tungsten commodity prices. If we are unable to obtain adequate financing on acceptable terms, or at all, we may be forced to delay, reduce in scope or cancel planned exploration, development or construction activities.

In addition, our ability to fund capital expenditures from internally generated cash flows will depend on our ability to successfully advance our projects to production and operate profitably, neither of which is guaranteed. If cash flows are insufficient or if we face difficulties raising debt or equity financing, we may be unable to carry out our business plan, complete development milestones or maintain our properties in good standing. Any delay or interruption to planned capital projects may increase costs, reduce future production capacity, and adversely affect our competitiveness.

Because tungsten projects typically require significant upfront investment and have long development timelines, any inability to secure timely financing could materially and adversely affect our business, results of operations and financial condition.

Actual capital and operating costs in respect of our mines and development projects may be significantly higher than estimated capital and operating costs.

Capital and operating cost estimates are based on the interpretation of geological data, the PFS stage and other technical studies, anticipated climatic conditions, market conditions for required products and services and other factors and assumptions regarding foreign exchange currency rates. Because we are in the exploration stage across all our project except Pilot Mountain, which is in the development stage, and have not yet established mineral reserves, on projects other than Pilot Mountain, these estimates are inherently more uncertain and subject to change as additional drilling, engineering and design work is completed. Any of the following events could affect the ultimate accuracy of such estimates: unanticipated changes in grade and tonnage of ore to be mined and processed; incorrect data on which engineering assumptions are made; lack of availability of key components or equipment; delay in construction schedules, unanticipated transportation costs; the inaccuracy of major equipment and construction cost estimates; the inaccuracy of operating cost or scale estimates; labor negotiations; changes in government regulation (including regulations regarding prices, cost of consumables, royalties, duties, taxes, permitting and restrictions on production quotas on exportation of minerals); raw material costs; changes in commodity prices, availability of financing on acceptable terms and title or right of use claims.

Lack of reliability and inaccuracies of historical information could hinder our exploration plans.

We have relied on, and the disclosure in the technical report summary for the Pilot Mountain project is in part based on, certain historical-geological, geochemical, geophysical and drilling data compiled by previous operators of Pilot Mountain. To the extent any such historical data is inaccurate, incomplete or was collected using methods that do not meet current industry standards, our exploration interpretations, mineral resource estimates and related plans may be adversely affected. In addition, cost estimates and assumptions used in connection with our exploration programs may not prove accurate. Such estimates are based on interpretations of geological information, anticipated site conditions and other technical and economic factors. Any of the following, among other risks and uncertainties described in this Annual Report on Form 20-F, could affect the accuracy of any such historical data or other estimates or assumptions: variability in grade or tonnage of mineralized material; errors or gaps in historical datasets; changes in drilling, assay or metallurgical costs; unexpected logistical or transportation constraints; availability of labor and equipment; or changes in permitting requirements, environmental regulations, taxes, royalties or land tenure matters. If these assumptions or historical datasets prove inaccurate, our exploration results, timelines and ability to advance our projects may be negatively affected.

Our actual costs may significantly exceed the estimated costs and economic returns estimated in our preliminary economic assessments and feasibility studies.

Feasibility studies, pre-feasibility studies and preliminary economic assessments (“PEAs”) are used to assess the economic viability of a mineral deposit. There is no certainty that existing or future pre-feasibility or feasibility studies or PEAs will be realized. Actual costs may significantly exceed estimated costs and economic returns may differ significantly from those estimated in the studies. There are many factors involved in the determination of the economic viability of a mineral deposit, including the achievement of satisfactory mineral reserve and mineral resource estimates, the level of estimated metallurgical recoveries, product quality and competition, capital and operating cost estimates and estimates of future tungsten and any by-product prices.

The Pilot Mountain project has completed the pre-feasibility stage, with the results of the PFS announced on June 30, 2026, supported by the U.S. Department of War Defense Production Act Title III award received in July 2025, and any advancement to a full feasibility study and a construction decision will depend on the results of ongoing exploration, permitting, financing and market conditions. The Tempiute project is a historical tungsten producer; a letter of intent was signed on October 31, 2024, and a definitive option agreement completed on January 25, 2025. The technical report summary for the Pilot Mountain tungsten project recommends that Pilot Mountain proceed to the definitive feasibility stage, into front-end engineering designs and continued drilling at Pilot Mountain. We advanced exploration activities at Tempiute through an extensive drilling program and expanded the Company’s land position at Tempiute. If the assumptions or estimations in the Pilot Mountain project PFS or the Tempiute project drilling program or other pre-feasibility workstreams are incorrect or if actual costs exceed those currently estimated, the projects may be economically unviable.

The accuracy of our mineral resource and mineral reserve estimates cannot be assured, and the volume of materials we are able to recover may be materially lower.

Our declared mineral resources and probable mineral reserves relate solely to our Pilot Mountain project; no mineral resources or mineral reserves have been established at any of our other projects. Our Tempiute project had no declared mineral resources as of June 30, 2026; work undertaken during fiscal year 2026 included drilling. No assurance can be given that the anticipated production will be achieved or that any indicated level of recovery of tungsten will be realized.

The estimation of mineral reserves and mineral resources is a subjective process that is partially dependent upon the judgment of the persons preparing the estimates. The process relies on the quantity and quality of available data and is based on knowledge, mining experience, statistical analysis of drilling results and industry practices. Valid estimates made at a given time may significantly change when new information becomes available. Our mineral resource estimates and mineral reserve estimates presented in this Annual Report on Form 20-F are, in accordance with Subpart 1300 of Regulation S-K, based on tungsten recoveries in small-scale laboratory tests and may not be indicative of the mineralization in the entire orebody, and we may not be able to achieve similar results in larger scale tests under on-site conditions or during production. Large-scale continuity and character of our deposits will only be determined once significant additional drilling and sampling have been completed and analyzed. Actual mineralization or formations may be different from those predicted.

Table of Contents

No assurance can be given that any part or all of our mineral resources will ever be converted into mineral reserves. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Due to the uncertainty that may be attached to inferred mineral resources, there is no assurance that inferred mineral resources will be upgraded to measured or indicated mineral resources as a result of continued exploration. If resources are upgraded to reserves, the ore volume and grade actually recovered by us may also differ from the estimated volumes and grades of the mineral reserves and mineral resources.

There are numerous uncertainties inherent in estimating mineral reserves and resources, including many factors beyond our control. The qualification of any ore as a reserve or resource estimate is materially dependent on prevailing metal prices and the cost of recovering and processing minerals at the individual mine sites. Prolonged declines in the market price of tungsten may render mineral reserves or resources containing relatively lower grades of mineralization uneconomical to recover and could thereby materially reduce our mineral resources or, if any, mineral reserves. Should such reductions occur, we may be required to take a material write-down of our investment in mining properties, reduce the carrying value of one or more of our assets or delay or discontinue production or the development of new projects, resulting in increased net losses and reduced potential future cash flow. Other than the probable mineral reserves declared at our Pilot Mountain project, we have not established mineral reserves, and our mine plans for other projects, if developed, will remain subject to significant uncertainty until reserves are delineated and even then such plans will remain subject to risks and uncertainties inherent in mining. Market price fluctuations of tungsten and other by-product metals such as silver and zinc, as well as increased production costs or reduced recovery rates, may render mineral resources or reserves containing relatively lower grades of mineralization uneconomical to recover and may ultimately result in a restatement of mineral reserves or resources. Short-term factors relating to the mineral reserve, such as the need for orderly development of ore bodies or the processing of new or different grades, the technical complexity of orebody, unusual or unexpected orebody formations, ore dilution or varying metallurgical and other ore characteristics may impair the profitability of a mine in any particular period. Failure to obtain or maintain necessary permits or government approvals, or changes to applicable tax and customs regimes or applicable legislation, could also influence the accuracy of our mineral resources or, if any, mineral reserves or cause us to reduce our mineral resources or, if any, mineral reserves.

Mineral resource estimates for properties that have not commenced production or at deposits that have not yet been exploited are based, in most instances, on very limited and widely spaced drill hole information, which is not necessarily indicative of conditions between and around the drill holes. Accordingly, such mineral resource estimates may require revision as more drilling information becomes available or as production experience is gained.

The mineral resource and mineral reserve estimates described in this Annual Report on Form 20-F should thus not be interpreted as assurances of commercial viability or potential or of the profitability of any future operations. Investors are cautioned not to place undue reliance on these estimates. A technical report summary issued by Samuel, NewFields and RESPEC on August 21, 2026, with an effective date of June 30, 2026, has been filed as Exhibit 96.1 to this Annual Report on Form 20-F. For a summary, please refer to Item 4.B.

Our mineral reserve and mineral resource estimates may prove inaccurate, and we may never be able to establish, replenish or expand our mineral resources or convert additional mineral resources into mineral reserves.

We have declared probable mineral reserves, as defined under Subpart 1300 of Regulation S-K, only at our Pilot Mountain project, and we have no proven mineral reserves at any of our projects; our other projects remain at the exploration stage with no established mineral resources or mineral reserves. Any potential future production beyond the mine plan contemplated by the PFS would depend on our ability to: (i) complete additional drilling and technical work to improve confidence in existing mineral resources, (ii) identify additional mineralized material through further exploration and (iii) demonstrate, through more advanced technical studies, that mineral reserves can be established. There is no assurance that any of these steps will be successful, that our estimated mineral reserves will be realized in the quantities or grades estimated, or that any of our other projects will ever support the declaration of mineral reserve.

Mineral resource estimates inherently involve uncertainty. Assumptions used by the qualified person to declare mineral resources may prove incorrect, or conditions may change with respect to operating or capital costs, metallurgical recoveries, product values, or other technical and economic factors. If the underlying assumptions used in preparing the mineral resource estimate for Pilot Mountain prove inaccurate, or if economic or technical conditions change, the mineral resources may be materially reduced, reclassified or rendered uneconomic and our ability to advance the project could be adversely affected.

There is no assurance that our exploration programs will result in the discovery of additional mineralization or that any existing or future mineral resources will ever be converted into mineral reserves.

Delays in the performance of any of the contractors, suppliers, consultants or other persons on which we are dependent in connection with our exploration, evaluation and potential construction activities, delay in or failure to receive the required governmental approvals and permits in a timely manner or on reasonable terms or termination of any existing or future required approvals or permits, or a delay or failure in connection with the completion and successful operation of the operational elements of any future mining operations could delay or prevent such projects from advancing to production.

The successful advancement of our projects through exploration to engineering and into construction and eventual production, including the development of the Pilot Mountain and Tempiute tungsten projects, is subject to a number of factors, including the availability and performance of engineering and construction contractors, mining contractors, suppliers and consultants, the receipt and maintenance of required governmental approvals and permits in connection with the development of mining facilities, the conduct of mining operations (including the receipt and maintenance of environmental permits) and the successful construction and operation of key infrastructure, such as ore passes, among other operational elements. Any delay in the performance of any one or more of the contractors, suppliers, consultants or other persons on which we are dependent in connection with our development activities, delay in or failure to receive the required governmental approvals and permits in a timely manner or on reasonable terms, the termination of any required approvals or permits, or a delay in or failure in connection with the completion and successful operation of the operational elements of any future mining operations could delay or prevent such projects from advancing to production.

There can be no assurance that any of our current or future exploration, development or production plans will be successful, that we will be able to obtain sufficient funds to finance exploration, development or production activities, that personnel and equipment will be available in a timely manner or on reasonable terms to successfully advance or complete such projects, that we will be able to obtain all necessary governmental approvals and permits or that the development and potential operating costs associated with the advancement of our projects will not be significantly higher than anticipated by us. Any of the foregoing factors could delay or prevent such projects from advancing to production, which in turn could adversely impact our operations and financial condition.

Our projects have no relevant operating history upon which to base estimates of future cash flow and may not be commercially viable.

Our projects have no relevant operating history upon which to base estimates of future cash flow. The Pilot Mountain project had small-scale production in the 1940s and the Tempiute project had production from the early 1900s up to the 1980s. The records of production and costs are not current enough to base estimates of future cash flow upon. In addition, historical production at Tempiute was largely from underground mining, which generally has higher costs than open pit mining, which was part of the PFS at Pilot Mountain. We are considering rehabilitation of underground workings at Tempiute to establish positions for underground drilling. If underground work would be undertaken, it would bring increased risks, including but not limited to, falls of ground and other safety risks. We are also looking at the potential of unrecovered metal in the tailings left from previous production at Tempiute. The capital expenditures and time required to develop our exploration projects into operating mines are considerable and changes in costs or construction schedules may affect project economics. Thus, it is possible that actual costs may change significantly and economic returns may differ materially from our estimates.

Commercial viability of a future mining project is predicated on many factors such as estimation of mineral resources (and their eventual conversion into reserves), anticipated metallurgical recoveries, environmental considerations, permitting and anticipated capital and operating costs, as well as available capital to develop such project. Any mineral resources estimated in technical assessments may not be realized or converted into reserves, and the level of future metal prices needed to ensure commercial viability may not materialize. Development projects are subject to the completion of successful feasibility studies and environmental assessments, issuance of necessary governmental permits and availability of adequate financing. Development projects are uncertain and it is possible that actual capital and operating costs and economic returns will differ significantly from those estimated. Consequently, there is a risk that future projects may be subject to write-down and/or closure as they may not be commercially viable.

We have negative cash flows from our operations.

For the fiscal year ended June 30, 2026, we sustained net losses from operations and had a negative operating cash flow of $6.0 million compared to negative operating cash flow of $1.1 million for the fiscal year ended June 30, 2025 and $0.7 million for the fiscal year ended June 30, 2024. As of June 30, 2026, we had cash and cash equivalents of approximately $52.5 million and accumulated losses of approximately $18.4 million. We have had negative operating cash flows in prior periods and may continue to do so and we will need to use available cash to fund any such negative cash flow.

Table of Contents

We anticipate that the Company will remain cash flow negative for several years. The generation of positive cash flow from operations will depend on the successful development and commencement of production at the Pilot Mountain and Tempiute tungsten projects and any delay in bringing these projects into production would extend the period during which we remain cash flow negative. We may, in the future, seek further financing through long-term debt from financial institutions, debt or equity financing though capital markets, or private placements. The availability of this capital is subject to general economic conditions and lender and investor interest in our projects and there can be no assurance that additional capital or financing will be available if needed or that, if available, the terms of such financings will be acceptable to us. Any changes in these estimates or adverse developments in the availability of capital could materially impact our financial performance and results of operations.

Our business and ability to advance our projects may be negatively affected by global financial conditions.

Global financial conditions continue to be characterized as volatile, including elevated inflation in mining inputs (labor, fuel, electricity, reagents, equipment and contractor services). Persistent input cost inflation or shortages in Nevada or other regions where we may operate due to local or global financial conditions could increase our capital and operating costs, extend schedules and adversely affect project economics. In recent years, global markets have been adversely impacted by various credit crises, significant fluctuations in fuel and energy costs and metals prices, inflation, geopolitical conflict and health pandemics. Many industries, including the mining industry, have been impacted by these market conditions, which have contributed to increased economic uncertainty, higher capital costs and, for pre-production companies like ours, potentially reduced access to financing. These factors have increased the risk of disruption to global trade flows and supply chains, including availability and lead times for mining and processing equipment.

Further, global financial conditions remain subject to sudden and rapid destabilizations in response to future events, as government authorities may have limited resources to respond to future crises. Global economic uncertainty, disruptions to global trade flows and supply chains and continued or worsened slowdown in the financial markets or other economic conditions, including but not limited to tariffs, consumer spending, employment rates, business conditions, inflation, fuel and energy costs, consumer debt levels, lack of available credit, the state of the financial markets, interest rates and tax rates may adversely affect our ability to secure project financing, maintain exploration and development timelines and advance our projects toward production.

Future crises may be precipitated by any number of causes, including natural disasters, geopolitical conflict or instability, changes to energy prices or sovereign defaults. If increased levels of volatility continue or in the event of a rapid destabilization of global supply chains or economic conditions, it may result in a material adverse effect on commodity prices, demand for metals, including tungsten, availability of credit, investor confidence and general financial market liquidity, all of which may adversely affect our ability to fund and advance our projects and the market price of our securities.

Foreign currency exchange rate fluctuations could adversely affect our operating costs, capital expenditures and results of operations.

A portion of our monetary assets and liabilities, including cash and cash equivalents, receivables and payables, as well as certain income and expense items such as operating expenses and capital expenditures, are and are expected to continue to be, denominated in currencies other than the U.S. dollar, principally the pound sterling. We hold significant amounts of cash from time to time in pounds sterling and a depreciation of this currency against the U.S. dollar could adversely affect our results of operations and our ability to advance our projects in the United States. Fluctuations in exchange rates between the U.S. dollar and other currencies could result in significant changes to our reported financial position and results, which may not be offset by corresponding changes in revenues. From time to time, we may use hedging arrangements, such as forward currency contracts, to manage foreign exchange exposure; however, these activities may be limited in scope and may not fully offset the impact of currency movements. As disclosed in Note 21 to the Consolidated Financial Statements and under Item 5, a 10% strengthening or weakening of sterling against the U.S. dollar would have a measurable impact on our profit or loss and equity. Any substantial or prolonged change in currency exchange rates could therefore have a material adverse effect on our business, financial condition and results of operations.

Disruption to current trade practices could have a material impact on our ability to procure inputs and equipment for our operations and projects, and, in the future, market our products.

Access to markets for any tungsten products we may produce in the future and our ability to procure inputs and equipment required for our projects and operations may be subject to interruptions or trade barriers due to policies and tariffs or import/export restrictions of individual countries. Any tungsten products we may sell in the future could be subject to tariffs or other trade measures that do not apply to producers in certain other jurisdictions, potentially affecting the competitiveness of our products and our ability to access certain markets.

Geopolitical tensions and trade disputes, particularly those affecting China, Europe and the United States, may impact the availability and pricing of tungsten. For example, in late 2024 and continuing into 2026, China instituted and expanded restrictions on exports of critical minerals, including tungsten, to the United States. Although China has since suspended certain of its export control measures relating to rare earths and certain other critical minerals, its restrictions on tungsten exports remain in place and have been further tightened, including through the announcement in December 2025 of arrangements limiting tungsten exports for the 2026-2027 period to a limited number of approved exporters, and negotiations between the United States and China are ongoing. With China accounting for a significant share of global tungsten supply, any changes in laws and regulations, export or import restrictions, tariffs or sanctions, or any perpetuation or escalation of any existing restrictions, tariffs or sanctions, could create volatility in the market and affect both the cost of inputs we require for our projects and the price environment for tungsten.

The recent and evolving introduction, modification, suspension, reimposition and threatened expansion of tariffs and other trade measures between major economies, including the United States, China and the European Union, have contributed to increased uncertainty in global trade and international supply chains. The scope, duration and application of these measures continue to evolve and remain subject to change. Tariffs, export controls, sanctions and other trade restrictions, together with the occurrence of trade disputes or other governmental actions relating to tariffs, trade agreements or trade policies, could adversely affect global economic conditions, disrupt international trade, increase market volatility and adversely affect the cost of inputs required for our projects, the price environment for tungsten and our business, financial condition, results of operations and prospects.

The imposition of any tariff on tungsten ore, concentrates, oxide and related materials produced and sold by us may adversely affect our business, financial condition and results of operations. In addition, tariffs on the import of critical equipment or materials required for either the capital development or operating phases of our projects could materially increase our capital or operating costs. Elevated tariffs could also limit the supply or availability of such equipment or materials, which may have a material adverse impact on our business.

Changes in geopolitical conditions, including a reduction or reversal of current trade restrictions and critical-minerals policies, could materially reduce the strategic importance of domestic tungsten projects like ours and adversely affect our business.

Our business strategy is premised in part on the current geopolitical and national-security environment, including ongoing trade tensions between the United States and China, China’s restrictions on exports of certain strategic minerals and U.S. government policies aimed at strengthening domestic supply chains for critical minerals. These developments have increased interest in and potential support for U.S.-based tungsten projects such as ours.

There is no assurance that these conditions will continue. Any improvement or de-escalation in U.S.-China relations, a reduction or removal of tariffs or export controls or a shift in U.S. government priorities regarding access to critical minerals could lessen or eliminate the perceived strategic value of domestic tungsten production. Similarly, if China were to resume or expand exports of tungsten or other related materials, global supply and pricing dynamics could change materially, which could reduce the demand for U.S. domestic tungsten production.

In addition, the U.S. Department of War and other federal agencies may decide not to continue, or may significantly reduce, efforts to promote domestic critical-minerals development. If government interest or policy support for domestic tungsten projects declines, our ability to attract financing, secure commercial partnerships or advance the development of our projects could be adversely affected. These developments could have a material negative impact on our business, prospects and the potential economic viability of our projects.

Increases in production costs may adversely affect our business.

Changes in our production costs could have a major impact on our profitability. Our principal production expenses are contractor costs, equipment, materials, personnel costs and energy. Changes in costs at any of our current or future mining and processing operations could occur as a result of unforeseen events, including international and local economic and political events, weather and climate conditions, increases in the costs of explosives, oil, steel, reagents, power supply and other consumables, union demands and scarcity of labor and could result in changes in profitability or reserve or resource estimates. Many of these factors may be beyond our control. For example, the availability of grid power in Nevada in the near term remains uncertain. Any delays in the delivery of grid power could significantly and adversely affect our ability to develop and operate mining projects, including Pilot Mountain and Tempiute and our financial condition and results of operations.

We rely on third-party suppliers for equipment hire and for a number of raw materials, including but not limited to fuel and, if we proceed to scale and advance towards production operations, steel and reagents. Any material increases in the cost of equipment hire or raw materials, or our inability to source viable and economic alternative third-party suppliers for the supply of our equipment and raw materials, could have a materially adverse effect on our results of operations or financial position.

We may not be able to secure financing on favorable terms, or at all, to meet our future capital needs.

In order to fund the costs associated with the exploration, development, mining and processing of minerals from our properties and our mine plans and to meet expected future obligations, we may, from time to time, be required to obtain additional financing. Given that our Pilot Mountain and Tempiute projects are currently in the development and exploration stages, respectively, and are not generating operating cash flows, our ability to fund such activities will depend heavily on access to external financing. Although we raised approximately $21 million in aggregate gross proceeds through a private placement of ordinary shares and received a $6.2 million award from the U.S. Department of War in July 2025, and raised approximately $68.3 million in aggregate gross proceeds in our initial public offering of ADSs completed in March 2026, we expect that we will continue to incur significant expenditures and will require substantial additional capital in future periods to advance feasibility, permitting and construction, including in respect of the initial capital expenditures of approximately $288.7 million for the Pilot Mountain project estimated in the PFS. Metal prices, environmental rehabilitation and restitution, revenue and income taxes, transportation and other operating costs, working capital needs, capital expenditures and geological results are also factors which may have an impact on the amount of additional financing that may be required.

Equity and debt markets are subject to significant volatility and because the Pilot Mountain and Tempiute projects have no recent production history, obtaining financing may be more difficult. In addition, tungsten prices are reported only in weekly quotations rather than through continuous live markets and this relative lack of transparency may make financing our projects more challenging compared to other metals with more liquid markets. Further, debt financing, if available, may also impose certain restrictions on our operating activities or include financial covenants, such as accompanying tungsten hedging requirements and minimum liquidity levels, or restrict our ability to enter into additional financing arrangements. There is no guarantee that such equity or debt financing will be available to us or that these financings would be obtained on terms favorable to us. Any inability to secure financing on favorable terms or at all may adversely affect our business and financial position and may result in a delay or indefinite postponement of exploration, development or production of any or all of our properties, or even a loss of exploration or development rights.

See Item 5.B.

If we incur indebtedness in the future, we may be subject to restrictive covenants and security arrangements that could limit our operational and financial flexibility and a default could have a material adverse effect on our business.

Any debt financing we obtain in the future may contain covenants that impose restrictions on our operations, such as limitations on additional indebtedness, liens, asset sales, investments, acquisitions, dividends, share repurchases or other distributions, as well as requirements to maintain certain financial ratios or other performance metrics. These restrictive covenants could restrict our ability to pursue strategic opportunities, respond to changing market conditions or fund necessary capital expenditures and could place us at a competitive disadvantage relative to peers not subject to such restrictions.

16

Table of Contents

If our indebtedness is secured by some or all of our assets, including our mineral properties, a default under the relevant financing agreements could result in the lender foreclosing on the collateral, which could include our most significant operating assets. In the event of a default, lenders may accelerate repayment of outstanding amounts and exercise remedies that could materially and adversely affect our financial condition and ability to continue as a going concern. Even if we are able to comply with these restrictive covenants, the need to monitor and manage compliance could divert management attention from operations. There can be no assurance that we will be able to meet any future debt service obligations or comply with restrictive covenants in any future debt instruments and any failure to do so could have a material adverse effect on our business, financial condition and results of operations.

We are subject to costs and risks associated with increased or changing laws and regulations affecting our business, including the need to obtain government permits, consents and licenses.

Exploration, development and mining activities are subject to laws and regulations governing health and work safety, employment standards, environmental matters, social matters, mine development, prospecting, mineral production, exports, taxes, labor standards, reclamation obligations and other matters. In Nevada, where our Pilot Mountain and Tempiute projects are located, our operations are also subject to U.S. federal laws as well as permitting requirements administered by the Nevada Division of Environmental Protection (“NDEP”) and the federal Bureau of Land Management (“BLM”). For example, development of the Pilot Mountain project will require a Plan of Operations (“PoO”) and related Environmental Assessment (“EA”) or Environmental Impact Statement (“EIS”) from the BLM, as well as applicable NDEP permits (including water pollution control, reclamation and air quality permits, as required). Future changes in applicable laws, regulations, agreements or changes in their enforcement or regulatory interpretation could result in changes in the legal requirements or in the terms of permits and agreements applicable to us or our properties, which could have a material adverse impact on our operations, including our exploration programs and future development projects. Although recent Executive Orders, including numerous issued in 2025 and 2026 relating to energy security, critical-mineral production and supply chain resilience, have emphasized federal priorities to strengthen domestic critical-minerals development, there can be no assurance that such priorities will continue.

Our projects are subject to review and permitting by both the NDEP and federal authorities. Obtaining necessary permits and licenses can be a complex, time-consuming process and there can be no assurance that required permits will be obtainable on acceptable terms, in a timely manner or at all. The costs and delays associated with obtaining permits and complying with these permits and applicable laws and regulations could stop or materially delay or restrict us from proceeding with the development of an exploration project or the operation or further development of a mine. Any failure to comply with applicable laws and regulations or permits, even if inadvertent, could result in interruption or closure of exploration, development or mining operations or material fines, administrative or legal proceedings brought by governmental agencies or other third parties, penalties or other liabilities, which could have an adverse effect on our business, financial condition or results of operation.

We are also subject to laws and regulations and acts by authorities related to environmental protection, health and safety, cultural and natural resource protection, water usage and reclamation that may limit or modify our exploration and development plans or impact our work programs, production volumes, costs and any future reserves and resources. For example, we acquired key water rights at Pilot Mountain; however, additional approvals may be required as projects advance. The Pilot Mountain and Tempiute projects will require an approved PoO, environmental assessments and reclamation bonding before construction can commence. The Company has an approved PoO for the Pilot Mountain project for exploration and pre-feasibility work to expand the disturbed land area in connection with drilling and related activities. The Company submitted a mine PoO for the Pilot Mountain project to the BLM which is expected to initiate the NEPA environmental review process with respect to mine development. The mine PoO and the related EA or EIS will be reviewed by federal and state regulators. There can be no assurance that the mine PoO, the EA or EIS will be accepted as submitted, or that they will not be significantly modified in a manner that could delay or prevent the planned works or the quality of our potential reserves or resources.

For any future mine development contemplated by the PFS, the Company may be required to submit additional filings to federal and state agencies, including an updated mine PoO and EA, or potentially a more expansive EIS. There can be no assurance that any such filings will result in the required approvals to advance the projects as planned, or at all, and any delay in, or expansion of the scope of, such environmental review could delay the development timeline contemplated by the PFS.

Disagreements with local communities and other stakeholders could adversely impact our business and reputation.

As a mining business, we may come under pressure in the jurisdictions in which we operate, or will operate in the future, to demonstrate that (i) other stakeholders (including employees, communities surrounding our operations and the countries in which we operate) benefit and will continue to benefit from our commercial activities and/or (ii) we operate in a manner that will minimize any potential damage or disruption to the interests of those stakeholders. We work to consider the interest of all stakeholders including but not limited to communities, but we may face opposition with respect to our current and future development, exploration and operation of projects and mines, which could materially adversely affect our business, results of operations and financial condition. Further, certain non-governmental organizations are often critical of the mining industry and related practices, including the use of hazardous substances in processing activities. The adverse publicity generated by these organizations or others related to extractive industries generally, or to our operations specifically, could negatively impact our reputation, financial condition and relationships with the communities in which we operate or our stakeholders generally. They may engage in protests or bring administrative or legal proceedings to object to the issuance of required permits, require environmental reviews or seek damages. These actions may be related not only to current activities, but also the historic mining activities of previous owners. Any such opposition, criticism, adverse publicity protests or proceeding could adversely affect us and result in the potential loss of our rights or failure of our projects.

Our business could be adversely affected by the failure or unavailability of certain critical assets or infrastructure.

Mining, processing, development and exploration activities depend on access to and an ability to maintain adequate and reliable infrastructure, including roads, railways, power sources and water supply. If the required infrastructure is not readily available, it may have to be built and there is no assurance that it can be built in a timely manner or at all. There is no assurance that we can access and maintain the infrastructure needed, or, where necessary, obtain rights of way, government authorizations and permits to construct or upgrade the same at a reasonable cost, in a timely manner, or at all. Access to infrastructure may also be interrupted by natural causes, such as drought, floods, earthquakes, landslides and other weather phenomena, or man-made causes, such as blockades, sabotage, conflicts, government issues, political events, protests, rationing or competing uses, as well as global pandemics. Inadequate, inconsistent or costly infrastructure could compromise many aspects of the project’s feasibility, viability and profitability, including, but not limited to the construction schedule, capital and operating costs.

In Nevada, our projects are located in remote areas and depend on the availability and maintenance of access roads, power lines and water infrastructure. Unusual or infrequent weather phenomena, sabotage, government or other interference in the maintenance or provision of such infrastructure could adversely affect our business, financial condition and results of operations. NV Energy, the electricity utility serving the area of the Pilot Mountain project, has indicated that it could take five years or more to deliver grid power to the site. As a result, alternative power sources are being evaluated for our Nevada projects, which may significantly increase potential operating costs or delay or prevent advancement. At the Tempiute project, although a power substation is located on the property, the condition, capacity and timing of any connection to key property infrastructure are uncertain and may require significant upgrades, so the availability of electricity from the grid may present a significant issue that could delay or prevent the advancement of the project. Changes in the quantity of water in regions where we operate, whether excessive or deficient amounts, may affect exploration and development activities, mining and processing operations, water management and treatment facilities, tailings storage facilities, closure and reclamation efforts and may increase levels of dust in dry conditions and land erosion and slope stability in case of prolonged wet conditions. Water shortages may also result from environmental and climate events that are out of our control and ability to manage. For example, inadequate rainfall or the occurrence of drought may stop operations, which could materially affect future production. Conversely, excessive rainfall or flooding may also result in operational difficulties, including geotechnical instability, increased dewatering demands and additional water management requirements. In addition, we cannot predict the potential outcome of pending or future legal proceedings or negotiations related to water rights, claims, contracts and uses, which may impact our operations. The loss of water rights, in whole or in part, or shortages of water to which we have established rights, could impact existing operations or prevent future exploration. Further, laws and regulations may be introduced in the jurisdictions in which we operate that could limit our access to sufficient water resources. Additionally, failure to manage water discharge or contamination risks could lead to environmental liabilities and reputational damage.

Concessions, authorizations, licenses and permits are subject to expiration, limitation on renewal and various other risks and uncertainties.

Our operations and exploration activities depend on permits, approvals and licenses from governmental regulatory agencies and other authorities (including federal agencies such as BLM, state agencies and county authorities) in the jurisdictions in which we operate. Our Pilot Mountain project currently consists of unpatented mining claims located on land managed by the BLM and we conduct exploration and early development work there through our U.S. subsidiaries. Our Tempiute project, by contrast, consists of both patented claims and unpatented mineral claims. We are subject to laws and regulations that can change at any time and changes in laws and regulations may require modifications to our plans and operations and result in unanticipated capital expenditures. We are also exposed to political and regulatory risk in our relationship with governmental and regulatory authorities that issue these permits and approvals.

Apart from unpatented mining claims, we may need to obtain various federal, state and county authorizations, licenses and permits from governmental or other regulatory bodies in connection with the planning, maintenance, operation and closure of our projects. Such authorizations, licenses and permits may be subject to fixed expiration dates or periodic review or renewal. There is no assurance that renewals will be granted as and when sought and there is no assurance that new conditions will not be imposed in connection with renewal. In addition, failure to comply with applicable laws and regulations, including failure to pay annual BLM and county claim maintenance fees, may invalidate title to mineral rights held by us.

If so, the costs of holding or renewing our unpatented mining claims and other approvals may render our business objectives unviable. Accordingly, we need to continually assess the economic and technical potential of each project to determine if the costs of maintaining the claims and permits are justified by the results of operations to date and we might elect to let some of our claims lapse. There can be no assurance that permits and approvals will be obtained on terms favorable to us, or at all, for our future intended exploration or development targets.

We are also subject to laws and regulations and acts by authorities, related to dams, caves, Indigenous People and Traditional Communities that may limit or modify our mining plans, impact our production volumes, costs and reserves and resources.

Our business faces uncertainties and risks relating to the development of its Pilot Mountain and Tempiute tungsten projects.

Our ability to achieve tungsten production in the future is dependent on the successful development of the Pilot Mountain and Tempiute tungsten projects. Pilot Mountain has completed the pre-feasibility study stage, with the results of the PFS announced on June 30, 2026, and Tempiute is a historic producing tungsten mine where drilling is underway as of H2 2026. There are many risks and unknowns inherent in all projects. For example, the economic feasibility of projects is based upon many factors, including:

19

Table of Contents

Unforeseen circumstances, including those related to the amount and nature of the mineralization at the development site, technological impediments to extraction and processing, legal requirements, governmental intervention, infrastructure limitations, transport issues, environmental issues and local community relations or other events, could result in the development of the Pilot Mountain and Tempiute tungsten projects becoming impractical or uneconomic. Further, actual costs and economic returns may differ materially from our estimates, or we may fail or be delayed in obtaining the governmental permits and approvals necessary in connection with the projects, in which case the projects may not proceed either on their anticipated timing or at all.

Frequently, new and/or expanded mining operations experience unexpected problems during the start-up phase and delays can often occur prior to production reaching its expected steady-state levels. We may also experience actual capital and operating costs and operating results that differ materially from those anticipated. In addition, experience from actual mining or processing operations may identify new or unexpected conditions that could reduce production below, or increase capital or operating costs above, current estimates. Accordingly, we cannot provide assurance that our activities will result in profitable mining operations at the Pilot Mountain and Tempiute tungsten projects.

The development of the Pilot Mountain project has been assisted by a $6.2 million award from the U.S. Department of War; approximately $6.1 million of this funding has been received as of the date of this Annual Report on Form 20-F. The final payments are anticipated on delivery of the final reporting and contract completion. We funded the PFS from cash on hand, including amounts received under the award. We have not yet secured the additional financing required to complete development of the Pilot Mountain project, including in respect of the initial capital expenditures of approximately $288.7 million estimated in the PFS. A budget of $28.0 million has been approved by our board for the Pilot Mountain for work through June 30 2027. Current expenditures relating to the Tempiute tungsten project are currently budgeted at $9.6 million for work through June 30, 2027, however this budget is subject to change, management approvals and regular project reviews. We expect to fund development and exploration work and initial scoping and engineering activities, as applicable, at Pilot Mountain and Tempiute from available cash resources.

The development and operation of the Pilot Mountain and Tempiute tungsten projects are subject to obtaining and maintaining various permits, licenses and regulatory approvals from local, regional and national authorities, including federal permits from the BLM for activities on unpatented mining claims and related annual BLM maintenance fees and filings, as well as state environmental approvals. The permitting process can be lengthy, complex and subject to change and there is no guarantee that all necessary approvals will be obtained in a timely manner or at all.

Cyberattacks, including unauthorized disclosure, destruction or modification of data through cybersecurity breaches, computer viruses or otherwise may adversely affect our business and reputation.

We are reliant on the continuous and uninterrupted operations of our information technology systems, including our networks, equipment, hardware, software, telecommunications and other information technology (collectively, “IT Systems”) and the IT Systems of our vendors and third-party service providers, to operate our business. User access and security of all IT Systems are critical elements to our operations. Our operations depend, in part, on how well we and our suppliers protect IT Systems against damage from a number of threats, including, but not limited to, cable cuts, damage to physical plants, natural disasters, terrorism, fire, power loss, hacking, computer viruses, vandalism and theft. These risks are evolving as IT Systems and cyberattacks or breaches become more sophisticated and prevalent. These cyberattacks are also becoming increasingly sophisticated through the use of artificial intelligence and machine learning tools and tactics and are often well-funded, including in some cases by state sponsors. These disruptions may also occur for non-malicious reasons, such as the widespread server-related outages caused by CrowdStrike’s defective software update in July 2024. Any IT System’s failure pertaining to availability, access or system security could result in disruption for personnel and could adversely affect our reputation, operations or financial performance.

Our operations also depend on the timely maintenance, upgrade and replacement of IT Systems, as well as preemptive expenses to mitigate the risks of failures. Increasingly, the operating and control systems at our projects rely on IT Systems to monitor ongoing operations and optimize performance. Our financial control and accounting systems depend on our IT Systems and our workforce increasingly works remotely, which has further increased our reliance on our IT Systems and associated risks. Adoption of new technology that promotes operational efficiency, such as the use of artificial intelligence, may further expose our IT Systems to risk. As our use of IT Systems increases and evolves and cybersecurity attacks become more sophisticated or pervasive, we may have to incur significant costs to upgrade our IT Systems to protect against any failures. New or improved IT Systems that we procure may have defects, not be installed properly or not integrate with our other IT Systems.

Table of Contents

Our IT Systems could be compromised by unauthorized parties attempting to extract sensitive, confidential or personal information, corrupting information or disrupting business processes or by inadvertent or intentional actions by our employees or vendors. A cybersecurity incident (including system-encrypting ransomware) resulting in a security breach or failure to identify a security threat could disrupt our business and could result in the loss of sensitive, confidential or personal information or other assets, as well as litigation, regulatory enforcement, violation of privacy and security laws and regulations and remediation costs.

The occurrence of one or more IT System’s failure could have effects including damage to our equipment, operational delays, loss or corruption of data, compromise of confidential or otherwise protected information, delay in the delivery of supplies and services, increased health and safety risks, increases in capital expenditures, loss of production, accidental discharge of regulated materials, expensive remediation efforts, distraction of management, damage to our reputation and events of noncompliance, which could lead to regulatory fines or penalties, or ransom payments. Any of the foregoing could have a material adverse effect on our results of operations and financial performance.

Although to date we have not experienced any material losses relating to cyberattacks or other information security breaches, there can be no assurance that we will not incur such losses in the future. Because critical minerals are considered strategically important in the United States, companies involved in their exploration and development may attract heightened attention from threat actors and our operations may face an elevated risk of cyberattacks compared to other mining companies. Our risk and exposure to these matters cannot be fully mitigated because of, among other things, the evolving nature of these threats. As a result, cybersecurity and the continued development and enhancement of controls, processes and practices designed to protect systems, computers, software, data and networks from attack, damage or unauthorized access remain a priority. As cyber threats continue to evolve, we may be required to expend additional resources to continue to modify or enhance protective measures or to investigate and remediate any security vulnerabilities.

Mining operations involve significant hazards and a high degree of risk.

Our exploration, development and mining operations are subject to significant risks inherent to the mining industry, some of which are beyond our control. Such risks include, but are not limited to, unusual and unexpected geologic formations, seismic activity, rock bursts, cave-ins, flooding, pit wall failure and other conditions involved in the drilling, blasting, mining and processing of material, any of which could result in damage to, or destruction of, mines and other producing facilities, damage to life or property, environmental damage, delays, suspensions or permanent cessation of activities, monetary losses and possible legal liability. We may undertake underground rehabilitation and development work in the year ahead which would bring additional risks and require additional safety measures, insurance and expense. Although we believe adequate precautions to minimize risk are being taken, mineral-process operations are subject to hazards such as fire, equipment failure or failure of retaining dams around tailings disposal areas, which may result in environmental pollution and consequent liability.

In addition, from time to time, we may be subject to governmental investigations and claims and litigation filed on behalf of persons who are harmed while at our properties or otherwise in connection with our operations. To the extent that we are subject to personal injury or other claims or lawsuits in the future, it may not be possible to predict the ultimate outcome of these claims and lawsuits due to the nature of personal injury litigation. Similarly, if we are subject to governmental investigations or proceedings, we may incur significant penalties and fines and enforcement actions against us could result in the closing of certain of our mining operations. If claims and lawsuits or governmental investigations or proceedings are ultimately resolved against us, it could have a material adverse effect on our financial performance, financial position and results of operations. Also, if we mine on property without the appropriate licenses and approvals, we could incur liability or our operations could be suspended.

Our business is exposed to the cyclicality of global economic activity.

Our business, financial performance and results of operations are significantly affected by the market prices and demand for the metals we are developing and expect to produce in the future, particularly tungsten from our Pilot Mountain and Tempiute projects, which in turn is driven by a wide variety of cyclical global macroeconomic factors.

Historically, prices and demand for metals have been subject to wide fluctuations which can be material and can occur over short periods of time and are affected by numerous factors beyond our control, including the cyclicality of consumer and industrial consumption. We cannot predict whether and to what extent metal prices and demand will rise or fall in the future. An increase in the production of metals worldwide or changes in, among other things, technology, industrial processes or consumer habits, including increased demand for substitute materials, may decrease the demand for these metals.

21

Table of Contents

A fall in demand, resulting from economic downturns or other factors, could also decrease the volume of metals that are able to sell once in production and, therefore, materially adversely impact our results of operations and financial position.

Future declines in tungsten prices could have an adverse impact on our results of operations and financial position and we may consider curtailing, modifying or discontinuing certain exploration, development or production operations. In addition, we may not be able to adjust production volume in a timely or cost-efficient manner in response to sustained changes in tungsten prices.

Lower utilization of capacity during periods of weak prices may expose us to higher unit production costs since a significant portion of our cost structure is fixed in the short term due to the high capital intensity of mining operations. If tungsten prices drop significantly, the economic prospects of the Pilot Mountain, Tempiute or any other tungsten projects we may acquire or develop could be significantly reduced or rendered uneconomic.

Low tungsten prices would affect our liquidity and ability to raise equity capital and borrow for any future mine development. If these conditions persist for an extended period, we may have to look for other sources of cash. Conversely, during periods of high demand, our ability to rapidly increase production capacity is limited, which could prevent us from meeting demand for our products and make acquiring long lead capital items more challenging and expensive.

Conditions of global conflict can bring significant market volatility in equity and debt capital markets, making financing and/or favorable terms more difficult to obtain and causing significant cost changes as well as supply chain challenges. We do not have any hedging in place for offtake of products, the costs or the supply of critical items such as, but not limited to, fuel and reagents for our mining projects.

Our business is subject to health, safety and environmental laws and regulations, and concessions, authorizations, licenses and permits are subject to expiration, suspension, limitation on renewal and various other risks and uncertainties.

Environmental laws and regulations may affect us. These laws and regulations set various standards regulating environmental quality, natural resources, reclamation and workplace health and safety. These laws and regulations are administered and enforced by a number of governmental authorities, such as the U.S. Environmental Protection Agency, the U.S. Mine Safety and Health Administration, the BLM, the Nevada Bureau of Mining Regulation and Reclamation and the NDEP. We may incur substantial costs to maintain compliance with environmental, health and safety laws and regulations and such costs could increase if existing laws and regulations are revised or reinterpreted or if new laws or regulations become applicable to our operations. Failure to comply with these environmental, health and safety laws and regulations may result in the orders suspending or restricting our operations, administrative civil or criminal liabilities, injunctions, third-party property damage or personal injury claims, investigatory cleanup or other remedial obligations, or other adverse effects on our business, financial condition or operations. Current and future legislative, regulatory and judicial action could result in changes to operating permits, material changes in operations and increased capital and operating expenditures, among others.

These laws and regulations require us to obtain federal and state permits and approvals for our operations and projects, including, for example, an approved PoO, environmental assessments, environmental impact statements and reclamation bonding for the Pilot Mountain and Tempiute projects. The Company has an approved PoO for the Pilot Mountain project for exploration and pre-feasibility work to expand the disturbed land area in connection with drilling and related activities. The Company submitted a mine PoO for the Pilot Mountain project to the BLM which is expected to initiate the NEPA environmental review process with respect to mine development. The mine PoO and the related EA or EIS will be reviewed by federal and state regulators. We also expect that any future exploration or development activities at our Tempiute project would require obtaining additional federal and/or state permits and approvals and may be subject to further environmental review. These permits and approvals are often necessary to start construction, continue operations or in connection with significant changes in existing operations. Our permits may be suspended or revoked in connection with violations of permit conditions or applicable environmental, health and safety laws and regulations, the impact of our operations on the environment or changes in the nature and scope of our activities. The duration and success of our efforts to obtain and renew licenses or permits are contingent upon many variables not within our control, including the interpretation of applicable requirements implemented by the authorities. We may not be able to obtain or renew licenses or permits that are necessary to our operations, or the cost to obtain or renew licenses or permits may exceed what we believe we can recover from the property. Any unexpected delays or costs associated with the licensing or permitting process could delay the exploration or development or impede the operation of any of our projects, which could adversely impact our operations and profitability.

Table of Contents

Certain environmental laws, such as the federal Comprehensive Environmental Response, Compensation and Liability Act, impose strict, joint and several liability for costs to investigate, remediate and restore sites where hazardous substances have been stored or released, including sites subject to legacy contamination. We may be required to investigate or remediate contaminated properties currently or formerly owned or operated by us or third-party sites at which waste materials we generated were disposed, regardless of whether such contamination resulted from our actions or from the conduct of others. Additionally, claims for damages to persons or property, including damages to natural resources, may result from the environmental, health and safety impacts of our operations.

In addition, mining is subject to potential risks and accidents that could result in serious injury or death to employees or members of our human capital. The impact of any such accidents and liabilities could affect the profitability of our operations, cause an interruption to operations, lead to a loss of permits or licenses, affect our reputation and our ability to obtain further permits or licenses, damage community and stakeholder relations and reduce our perceived appeal as an employer.

Substantial and increasingly intense competition may harm our business.

The mineral exploration, development and production industry is intensely competitive in all of its phases and we must compete in all aspects of our operations with a substantial number of large established mining companies, as well as mid-tier and junior miners and exploration companies with greater liquidity, greater access to credit and other financial resources, newer or more efficient equipment, lower-cost structures, more effective risk management policies and procedures and/or greater ability than us to withstand losses.

Many of these companies currently have greater resources than we do to be able to identify and evaluate prospective mineral projects or titles and often have greater financial resources to be able to pursue their acquisition. In addition, we also encounter competition for the hiring of key personnel whether as employees, consultants or other service providers. The mineral exploration and mining industry is currently facing a shortage of experienced mining professionals. Moreover, the demand for exploration equipment (including drilling rigs), technical consultants and assay labs is very high and such personnel and services may not be available, or if they are, at costs that are greater than expected resulting in an increase in our costs. This competition affects us by increasing the time and cost to conduct exploration activities.

There is also a limited supply of desirable mineral properties available for claim staking, leasing, exploration or acquisition in the areas where we operate, such as Nevada and in other jurisdictions where we may contemplate conducting activities. Many companies and individuals are engaged in the mining business and, as a result, the competition for these properties is intense. We may be at a competitive disadvantage in acquiring talent or mining properties, as we must compete with these companies and individuals, some of which may have greater financial resources and larger technical staff than us or be able to leverage synergies that are not available to us.

Our competitors may be able to respond more quickly to new laws or regulations or emerging technologies or devote greater resources to the expansion of their operations than we can. In addition, current and potential competitors may make strategic acquisitions or establish cooperative relationships among themselves or with third parties. Accordingly, there can be no assurance that we will be able to compete successfully for new mining properties. The increase in tungsten prices over the past two years has resulted in an increased interest in active tungsten projects and more competition generally.

The increase in the price of tungsten over the past two years has attracted a number of companies to focus on mining and exploration for tungsten in the United States and elsewhere. For example, several historically producing mines have been acquired by companies with the objective of re-starting production. The increased focus on tungsten in the mining industry may bring increased competition for capital and resources needed for new tungsten mines. New increased mining opportunities may create the perception or reality of increased supply of tungsten, which may negatively affect the price of tungsten and create competition for off-take contracts and downstream processing facility capacities.

As global efforts to reduce dependency on Chinese tungsten increase and Chinese export bans come into effect, competition among non-Chinese producers and new entrants into the tungsten supply chain may also intensify. This new competitive dynamic could impact pricing, market share and long-term profitability. Failure to maintain cost competitiveness or secure strategic partnerships may adversely affect our market position.

If we lose key personnel, our business, financial condition and results of operations may be adversely affected.

Our business is dependent on retaining the services of our key management personnel with a variety of skills and experience, including in relation to the development and operation of our projects in Nevada and any other jurisdictions in which we may operate in the future. Our success is and will continue to be dependent to a significant extent on the expertise and experience of our directors and senior management. The loss of the services of key personnel could have a materially adverse effect on our business. Our success will also depend to a significant degree upon the contributions of qualified technical personnel and our ability to attract and retain highly skilled personnel. Competition for such personnel is significant. Any inability to attract and retain these people could have a material adverse effect on our business and operations.

Labor disputes may disrupt our operations from time to time.

Production at our mining operations and development projects is dependent upon the efforts of our employees and our operations would be adversely affected if we fail to maintain satisfactory labor relations. Factors such as work slowdowns or stoppages caused by the attempted unionization of operations and difficulties in recruiting qualified miners and hiring and training new miners in Nevada and other jurisdictions where we operate could materially adversely affect our business and results of operations. Such events could reduce production, delay project timelines and result in us not meeting our business objectives.

In addition, relations between us and our employees may be affected by changes in the scheme of labor relations and employment laws introduced by the relevant governmental authorities in whose jurisdictions we carry on business. Changes in such legislation or in the relationship between us and our employees may have a material adverse effect on our business, financial condition and results of operations. Furthermore, we are reliant on the integrity and good conduct of our employees and are subject to the risk that employee misconduct could occur. Although we take precautions to prevent and detect employee misconduct, these precautions may not be effective and we could be exposed to unknown and unmanaged risks or losses, including regulatory sanctions and serious harm to our reputation. Our adoption of the QCA Corporate Governance Code and the Code of Conduct (as defined below), among other governance and compliance policies and processes, may not prevent incidents of theft, dishonesty or other fraudulent behavior nor can we guarantee compliance with legal and regulatory requirements. If material employee misconduct does occur, our business, financial condition and results of operations could be adversely affected.

Our business could be adversely affected by the performance of our counterparties and outside contractors we do not control.

It is common industry practice for certain aspects of mining operations including, but not limited to, drilling, blasting and construction, to be conducted by one or more outside contractors and we may rely on outside contractors for such future activities. We also rely on third parties for certain transportation, logistics, maintenance and sample analysis. Deficient or negligent work, or work not completed in a timely manner, could have a material adverse effect on our business and operations. We are also subject to a number of risks associated with the use of such contractors, including, but not limited to: (a) us having reduced control over the aspects of the operations that are the responsibility of a contractor; (b) failure of the contractor to perform work properly or at a satisfactory level of quality and safety; (c) failure of a contractor to perform under its agreement(s), including, but not limited to, inability to meet the contractual timelines or to otherwise deliver in accordance with the terms of the contract; (d) inability to replace the contractor if the contractual relationship is terminated; (e) interruption of operations in the event the contractor ceases operations as a result of a contractual dispute with us or as a result of insolvency or other unforeseen events (including events of force majeure); (f) failure of the contractor to comply with applicable legal and regulatory requirements; and (g) an inadequate contractor cybersecurity program or customer data management and privacy, exposing us to external attacks or leaking of our confidential information, any of which could have a material adverse effect on our business, financial condition or results of operations.

Our directors and officers are or may become subject to conflicts of interest.

Certain of our directors and officers are or may become associated with other mining and/or mineral exploration and development companies, including entities with current or potential operations in Nevada or in the tungsten sector, which may give rise to conflicts of interest. Directors who have a material interest in any person who is a party to a material contract or a proposed material contract with us are required to disclose that interest and abstain from voting on any resolution to approve such a contract. In addition, directors and officers are required to act honestly and in good faith with a view to our best interests. Further, any failure of our directors or officers to address these conflicts in an appropriate manner or to allocate opportunities that they become aware of to us in accordance with applicable corporate governance policies and relevant laws could have a material adverse effect on our business, financial condition, results of operations, cash flows or prospects.

The acquisition of title to mineral properties is a detailed and time-consuming process and there is no guarantee that title to such mineral properties will not be contested or challenged.

The acquisition of title to mineral properties is a very detailed and time-consuming process. Title to and the area of mineral concessions may be defective or disputed. Although we believe we have taken reasonable measures to ensure proper title to our interests in our properties, there is no guarantee that title to such mineral property interests will not be contested or challenged. Third parties may have unregistered or unknown valid claims underlying portions of our interest, including prior unregistered liens, agreements, transfers, royalties or claims, and title may be affected by, among other things, undetected defects. In some cases, title to mineral rights and surface rights has been divided and we may hold only surface rights or only mineral rights over a particular property, which can lead to potential conflict with the holder of the other rights. In the United States, unpatented mining claims are subject to oversight by BLM and require the payment of annual maintenance fees and compliance with other regulatory obligations; failure to meet such requirements could result in loss of title.

Our mineral property interests may be subject to prior unregistered agreements or transfers and ownership may be affected by undetected irregularities. Mining rights may be contested and, if such contest is successful, the development of our assets and/or operations may be adversely affected.

Title insurance is generally not available for mineral properties and our ability to ensure that we have obtained secure claim to individual mineral properties or mining concessions may be severely constrained. We rely on title information and/or representations and warranties provided by our grantors. Any challenge to our title could result in litigation, insurance claims and potential losses, delay the exploration and development of a property and ultimately result in the loss of some or all of our interest in the property. In addition, if we mine on property without the appropriate title, we could incur liability for such activities.

Our insurance policies may not be sufficient to cover all claims.

Our business and operations are subject to a number of risks and hazards generally, including adverse environmental conditions, industrial accidents, labor disputes, unusual or unexpected geological conditions, ground or slope failures, cave-ins, catastrophic equipment failures, changes in the regulatory environment and natural phenomena such as inclement weather conditions, floods and earthquakes, as well as potential supply chain disruptions and cybersecurity incidents. Such occurrences could result in damage to mineral properties or production facilities, personal injury or death, environmental damage to our properties or the properties of others, delays in mining, monetary losses and possible legal liability.

Although we maintain insurance to protect against certain risks in such amounts as we consider reasonable, our insurance will not cover all the potential risks associated with a mining company’s operations. We may also be unable to maintain insurance to cover these risks at economically feasible premiums. Insurance coverage may not continue to be available or may not be adequate to cover any resulting liability. Moreover, insurance against risks such as environmental pollution or other hazards as a result of exploration, development and production is not generally available to us or to other companies in the mining industry on acceptable terms. We might also become subject to liability for pollution or other hazards that may not be insured against or that we may elect not to insure against because of premium costs or other reasons. Losses from these events or delays in cash receipt from an insurance claim recovery may cause us to incur significant costs and cash outflows that could have a material adverse effect upon our financial performance and results of operations. In addition, certain policies may include deductibles, exclusions or coverage limitations that could result in us bearing a portion of any loss. The Company carries certain insurance coverage, including for third-party liability and directors’ and officers’ liability, but there can be no assurance that such insurance will be adequate to cover any particular loss or that it will continue to be available on acceptable terms, if at all. If the Company elects to work underground, this may increase insurance costs.

Natural disasters, as well as geotechnical and hydrological conditions, such as landslides, droughts, pit wall failures, tailings dam failures, dry stack tailings failures and rock fragility and climate change may have an adverse effect on our business.

We and the mining industry are facing continued geotechnical challenges, which could adversely impact our production and profitability. Unanticipated adverse geotechnical and hydrological conditions, such as landslides, droughts, pit wall failures, tailings dam failures, dry stack failures and rock fragility may occur in the future and such events may not be detected in advance. Geotechnical instabilities and adverse climatic conditions can be difficult to predict and are often affected by risks and hazards outside of our control, such as severe weather, including extreme heat events and significant rainfall, which may lead to periodic floods, mudslides, wall instability and seismic activity, which may result in slippage of material. There can be no assurance that future weather events will not adversely affect mining and exploration activities at our Nevada projects or at any other locations we may operate in the future. In particular, mining, drilling and exploration activities may be suspended due to poor ground conditions, ore haulage activities may be slowed or delayed as roads may be temporarily flooded and deposits where the host rock is clayish in nature may have to be mined or processed at slower than anticipated rates and/or mixed with lower grade stockpile ore. At certain locations, recoveries may be affected by water availability and quality, which is a material consideration in arid regions such as Nevada. Furthermore, the occurrence of physical climate change events may result in substantial costs to respond to the event and/or recover from the event and to prevent recurrent damage, through either the modification of, or addition to, existing infrastructure at our operations. The scientific community has predicted an increase, over time, in the frequency and severity of extraordinary or catastrophic natural phenomena as a result of climate change. We can provide no assurance that we will be able to predict, respond to, measure, monitor or manage the risks posed as a result.

Geotechnical failures could result in limited or restricted access to mine sites, suspension of operations, government investigations, increased monitoring costs, remediation costs, loss of ore and other impacts, which could cause one or more of our projects to be less profitable than currently anticipated and could result in a material adverse effect on our results of operations and financial position.

Our potential mining and processing operations are, in some instances, energy intensive. We acknowledge climate change as an international and community concern. Physical climate change events and the trend toward more stringent regulations aimed at reducing the effects of climate change could adversely impact our operations, the operations of our supply chain partners, the demand for the minerals produced by our operations, our decisions to pursue future opportunities or maintain existing operations, which could have an adverse effect on our business and future operations. We can provide no assurance that efforts to mitigate the risks of climate change will be effective and that the physical risks of climate change will not have an adverse effect on our operations and profitability. In addition, as climate change is increasingly perceived as an international and community concern, stakeholders may increase demands for emissions reductions and call upon mining companies to better manage their consumption of climate-relevant resources. Such regulatory requirements and stakeholder requests and demands may have an adverse impact on us. Further, the supply and availability of electrical components could be challenging and create delays in our projects.

Our business may be adversely affected by increasing environmental, social and governance-related legal requirements or stakeholder-driven demands, including pertaining to climate change.

Recent regulatory, compliance and transparency demands on environmental, social and governance (“ESG”) matters by regulatory authorities, investors, financial institutions, insurers and reinsurers, among others, may represent a challenge for us in terms of transparency, timeliness, veracity and depth of the information revealed. ESG requirements and disclosure expectations differ across jurisdictions and stakeholders and are subject to change over time at the local, state or federal level. ESG is a complex and evolving area of regulatory and stakeholder requirements and our communications or actions in this area may give rise to scrutiny, protests or legal challenges by special interest groups or others. Our disclosures with respect to ESG matters may be based on hypothetical expectations and assumptions that may or may not be representative of current or actual risks or events or forecasts of expected risks or events, including the costs associated therewith. Mandatory ESG-related disclosures are also emerging as an area where we may be, or may become, subject to required disclosures in certain jurisdictions and any such mandatory disclosures may similarly necessitate the use of hypothetical, projected or estimated data, some of which is not controlled by us and is inherently subject to imprecision. Disclosures reliant upon such expectations and assumptions are necessarily uncertain and may be prone to error or subject to misinterpretation given the long timelines involved and the lack of an established single approach to identifying, measuring and reporting on many ESG matters. Although we may adopt ESG-related targets, we may not be able to meet them in the manner or on such a timeline as initially contemplated and we cannot guarantee that such targets will improve our ESG profile, including, but not limited to, as a result of unforeseen costs or technical difficulties associated with achieving such results. Further, despite any voluntary actions, we may receive pressure from certain investors, lenders, employees or other groups to adopt more aggressive ESG-related targets or policies, but we cannot guarantee that we will be able to implement such targets because of potential costs or technical or operational obstacles. Furthermore, our approach to ESG matters may become the subject of scrutiny by stakeholders that may have divergent or conflicting views regarding ESG or in connection with laws, regulations and policies aimed at restricting or discouraging the consideration of ESG factors by companies, which could adversely affect our reputation, business, financial performance, market access and growth.

Our reputation, as well as our stakeholder relationships, could be adversely impacted as a result of, among other things, any failure to meet any ESG plans or targets or stakeholder perceptions of statements made by us, our employees and executives, agents or other third parties or public pressure from investors or policy groups to change our policies. Furthermore, public statements with respect to ESG matters, such as emission reduction goals, other environmental targets or other commitments addressing certain social issues, are becoming increasingly subject to heightened scrutiny from public and governmental authorities related to the risk of potential “greenwashing,” i.e., misleading information or false claims overstating potential ESG benefits. We may face increased litigation risk from private parties and governmental authorities related to our ESG efforts. Additionally, any such alleged claims of greenwashing against us or others in our industry could lead to negative sentiment and the diversion of investment. To the extent that we are unable to respond timely and appropriately to any negative publicity, our reputation could be harmed. Damage to our overall reputation could have a negative impact on our financial results and require additional resources to rebuild our reputation.

In addition, certain governments have introduced or are introducing climate change legislation and treaties at the international, national, state/provincial and local levels. Regulation relating to greenhouse gas emissions (such as carbon taxes) and energy efficiency is becoming more stringent in certain jurisdictions. If these regulatory trends continue, this may result in increased costs at our operations.

We may pursue strategic acquisitions or investments. The failure of an acquisition or investment to produce the anticipated results, or the inability to integrate an acquired company fully, could harm our business.

We may actively pursue the acquisition of exploration, development and production assets consistent with our acquisition and growth strategy. From time to time, we may also acquire securities of or other interests in companies with respect to which we may enter into acquisitions or other transactions. Acquisition transactions involve inherent risks, including but not limited to: (i) accurately assessing the value, strengths, weaknesses, contingent and other liabilities and potential profitability of acquisition candidates; (ii) ability to achieve identified and anticipated operating and financial synergies; (iii) unanticipated costs; (iv) diversion of management attention from existing business; (v) potential loss of our key employees or key employees of any business acquired; (vi) unanticipated changes in business, industry or general economic conditions that affect the assumptions underlying the acquisition; and (vi) decline in the value of acquired properties, companies or securities.

To acquire properties and companies, we may be required to use available cash, incur debt, issue additional ADSs or other securities or a combination of any one or more of these. This could affect our future flexibility and ability to raise capital, to explore, develop and operate our properties and could dilute existing shareholders and decrease the trading price of our securities. There is no assurance that when evaluating a possible acquisition, we will correctly identify and manage the risks and costs inherent in the business to be acquired. There may be no right for our shareholders to evaluate the merits or risks of any future acquisition undertaken by us, except as required by applicable laws and regulations.

Evaluating, negotiating and completing an acquisition may also require substantial management time commitments, regardless of whether the acquisition is completed. The negotiation of potential acquisitions and the integration of acquired operations could disrupt our business by diverting management and employees’ attention away from day-to-day operations.

Any one or more of these factors or other risks could cause us not to realize the anticipated benefits of an acquisition of properties or companies and could have a material adverse effect on our financial condition.

We may enter into joint ventures or other strategic arrangements, which could limit our ability to control project development and expose us to additional risks.

We may from time to time enter into joint ventures, partnerships or other strategic arrangements with third parties in connection with the exploration, development or operation of our projects. These arrangements may involve the sharing of ownership, management and operational control, which could result in us having to rely on our partners for technical expertise, access to financing, regulatory compliance or day-to-day operational decisions. Our interests may not be aligned with those of our partners and disagreements or disputes could arise that may delay decision-making, result in litigation or arbitration or otherwise impair the development or operation of the project.

In addition, our partners may fail to meet their obligations, experience financial or operational difficulties or take actions contrary to our interests, including failing to fund their share of project costs. If we are unable to enforce our rights under the relevant agreements, we may be required to contribute more capital or assume additional obligations to protect our investment.

Any loss of control over a material project, or a failure by a partner to perform its obligations, could have a material adverse effect on our business, results of operations and financial condition.

Our reputation could be damaged, including as a result of the actual or perceived occurrence of any number of events and could include any negative publicity, whether true or not, which could have an adverse impact on our financial performance, cash flows and growth prospects.

As a result of the increased usage and the speed and global reach of social media and other web-based tools used to generate, publish and discuss user-generated content and to connect with other users, companies today are at a much greater risk of losing control over how they are perceived in the marketplace. Damage to our reputation can be the result of the actual or perceived occurrence of any number of events, including environmental incidents, safety events, permit or regulatory compliance issues, disputes with local communities or negative commentary from stakeholders or media and could include any negative publicity, whether true or not. While we intend to protect our image and reputation, we do not ultimately have direct control over how we are perceived by others.

Reputational damage, including reputational damage to other mining companies operating in jurisdictions where we operate, may result in decreased investor confidence, increased challenges in developing and maintaining community and stakeholder relations, increased regulatory scrutiny and an impediment to our overall ability to advance our projects and strategy, which could have a material adverse impact on our results of operations, financial condition and prospects. While we intend to operate in a socially responsible manner, there is no guarantee that our efforts in this respect will mitigate this potential risk.

Uncertainties relating to taxes in the countries in which we have operations could materially adversely affect our financial condition and results of operations and reduce net returns to our shareholders.

Our taxes are affected by several factors, some of which are outside of our control, including the application and interpretation of the relevant tax laws and treaties. If our filing position, application of tax incentives or similar “holidays” or our eligibility for treaty benefits were to change or be challenged for any reason, this could have a material adverse effect on our business, financial condition and results of operations. For example, if we were to fail to qualify for benefits under the U.S.-U.K. income tax treaty (such as due to the lack of sufficient trading of our ADSs), we could be subject to withholding taxes on payments we receive from our U.S. subsidiaries.

We may be subject to tax audits by various tax authorities in the jurisdictions where we operate. Tax audits may result in additional tax, interest payments and penalties which would negatively affect our financial condition and operating results. New laws and regulations or changes in tax rules and regulations or the interpretation of tax laws by the courts or the tax authorities may also have a substantial negative impact on our business. There is no assurance that our current financial condition will not be materially adversely affected in the future due to such changes.

We are unable to predict what tax reform may be proposed or enacted in the future or what effect such changes would have on our business, but such changes, to the extent they are brought into tax legislation, regulations, policies or practices in jurisdictions in which we operate, could increase the estimated tax liability that we have expensed to date and paid or accrued on our balance sheets and otherwise affect our financial position, future results of operations, cash flows in a particular period and overall or effective tax rates in the future in countries where we have operations, reduce post-tax returns to our shareholders and increase the complexity, burden and cost of tax compliance.

Our ability to utilize tax losses carryforwards or any other tax attributes to offset taxable income may be subject to various limitations under U.S. or U.K. tax laws. Furthermore, it is possible that amounts shown on our financial statements as deferred tax assets may in fact not be utilized in full to reduce our future taxable income and such amounts may require adjustments from time to time.

We will incur increased costs as a result of operating as a public company in the United States.

We are a public company with shares admitted to trading on AIM and our ADSs admitted to trading on the NYSE American and, as a result, we have incurred and will continue to incur significant legal, accounting and other expenses that we would not incur if our shares were traded solely on AIM. As a public company listed on a stock exchange in the United States, we are subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act, as well as rules adopted and to be adopted, by the Securities and Exchange Commission (the “SEC”) and the NYSE American. Our management and other personnel will need to devote a substantial amount of time to these compliance initiatives and may not effectively or efficiently manage the ongoing transition to also being a public company in the United States. Moreover, we expect these rules and regulations to substantially increase our legal and financial compliance costs and to make some activities more time-consuming and costly. For example, we expect these rules and regulations to make it more difficult and more expensive for us to obtain director and officer liability insurance and we may be forced to accept reduced policy limits or incur substantially higher costs to maintain the same or similar coverage. We cannot predict or estimate the amount or timing of additional costs we may incur to respond to these requirements. The impact of these requirements could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, our board committees or as executive officers.

In addition, these rules and regulations are often subject to varying interpretations and evolving guidance, which may create continuing uncertainty regarding compliance obligations and require ongoing revisions to our disclosure and governance practices, further increasing compliance costs.

Certain members of our management team have experience managing a company publicly traded in the United States and complying with the increasingly complex laws pertaining to public companies in the United States. However, other members of the Board and management do not have such experience. The additional demands associated with being a public company in the United States may disrupt regular operations of our business by diverting the attention of some of our senior management team away from revenue producing activities to management and administrative oversight, adversely affecting our ability to attract and complete business opportunities and increasing the difficulty in both retaining professionals and managing and growing our businesses.

In addition, pursuant to Section 404(a) of the Sarbanes-Oxley Act, our senior management will be required to furnish a report on the effectiveness of our internal control over financial reporting in our annual report on Form 20-F beginning with our second annual report on Form 20-F after our initial public offering which occurred in March 2026 (our “IPO”). While we remain an emerging growth company, we will not be required to include an attestation report from our independent registered public accounting firm mandated by Section 404(b). However, preparing for eventual compliance with Section 404 will nonetheless require dedicating internal resources, potentially engaging outside consultants and adopting detailed work plans and testing procedures. Despite these efforts, there is a risk that we may be unable to conclude, within the prescribed time frame or at all, that our internal control over financial reporting is effective. If we identify one or more material weaknesses, it could result in a loss of confidence in the reliability of our financial statements and an adverse reaction in the financial markets.

Our management team may not successfully or efficiently manage our ongoing transition to being a public company in the United States subject to significant regulatory oversight and reporting obligations under the U.S. federal securities laws and the continuous scrutiny of securities analysts and investors.

In addition, the public reporting obligations associated with being a public company in the United States may subject us to litigation as a result of increased scrutiny of our financial reporting. If we are involved in litigation regarding our public reporting obligations, this could subject us to substantial costs, divert resources and management attention from our business and seriously undermine our business.

Failure to comply with existing and future rules and obligations of the stock exchanges on which our securities are listed may subject us, our subsidiaries and/or members of our management team to, among other things, delisting, litigation, investigations, expenses, fines and other applicable sanctions.

Any of these effects could harm our business, financial condition and results of operations.

Adverse outcomes in legal proceedings could subject us to substantial damages and adversely affect our results of operations and profitability.

We may from time to time be party to civil, environmental, tax, labor, criminal, regulatory and administrative or legal proceedings, as well as arbitration and administrative proceedings. We cannot guarantee that the outcome will be favorable to us and that we have adequately recorded provisions for any such proceedings.

Decisions contrary to our interests that involve substantial amounts, especially in cases in which we have not recorded provisions or in which the amounts provisioned are lower than final adjudicated amounts, could prevent our conduct of business as planned and may have an adverse effect on our results of operations and business. In addition, government authorities may have understandings or interpretations different from ours in connection with the conduct of our business and may subject us to contingencies for other reasons that require us to spend significant amounts or lead to the loss of grants from government authorities.

Moreover, we may not have sufficient funds to post collateral or provide guarantees in judicial or administrative proceedings involving substantial amounts. Even if we do not post such collateral or provide guarantees, we will be liable for paying any amounts due pursuant to any unfavorable outcomes in legal proceedings. We cannot assure you that, if we cannot make such payments, our assets, including financial assets, will not be attached or that we will be able to obtain tax good-standing certificates, all of which may have a material adverse effect on our business, financial condition and results of operations.

See Item 8 for further information.

We may identify material weaknesses in our internal control over financial reporting and, if we fail to maintain effective internal controls over financial reporting, we may be unable to accurately report our results of operations, meet our reporting obligations and/or prevent fraud.

Prior to our IPO, we were not an SEC registrant and were not required to assess or report on the effectiveness of our internal control over financial reporting under the Sarbanes-Oxley Act.

Table of Contents

In connection with the audit of our Consolidated Financial Statements for the fiscal year ended June 30, 2026, our external auditors obtained an understanding of our internal controls relevant to their audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of our internal controls in accordance with the provisions of the Sarbanes-Oxley Act.

We are required to comply with the requirements of the Sarbanes-Oxley Act, including establishing and maintaining effective internal control over financial reporting and disclosure controls and procedures. As an emerging growth company, we are not required to comply with the auditor attestation requirement under Section 404(b) of the Sarbanes-Oxley Act until we cease to qualify as an emerging growth company. However, our management will be required to assess the effectiveness of our internal control over financial reporting under Section 404(a) beginning with our second annual report on Form 20-F following our IPO.

If we fail to maintain an effective internal control environment, we could suffer material misstatements in our financial statements, fail to meet our reporting obligations or fail to prevent fraud, which would likely cause investors to lose confidence in our reported financial information. This could, in turn, limit our access to capital markets, harm our results of operations and lead to a decline in the trading price of our securities. Additionally, ineffective internal control over financial reporting could expose us to increased risk of fraud or misuse of corporate assets and subject us to potential delisting from the NYSE American, regulatory investigations and civil or criminal sanctions.

Our testing of internal controls may in the future reveal deficiencies that are considered material weaknesses or significant deficiencies, any of which could have a material adverse effect on our business and results of operations.

Disclosure controls and procedures over financial reporting may not prevent or detect all errors or acts of fraud.

Disclosure controls and procedures, including internal controls over financial reporting, are designed to provide reasonable assurance that information required to be disclosed by us in reports filed or submitted under the Exchange Act is accumulated and communicated to management and recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

These disclosure controls and procedures have inherent limitations, which include the possibility that judgments in decision-making can be faulty and result in errors or mistakes. Additionally, controls can be circumvented by any unauthorized override of the controls. Consequently, our business is exposed to risk from potential noncompliance with policies, employee misconduct, negligence and fraud, which could result in regulatory sanctions, civil claims and serious reputational or financial harm. In particular, it is not always possible to deter employee misconduct and the precautions we take to prevent and detect this activity may not always be effective. Accordingly, because of the inherent limitations in the control system, misstatements due to error or fraud may occur and not be detected.

We may also acquire businesses with unknown liabilities, contingent liabilities, internal control deficiencies or other risks. We have policies and procedures to review potential acquisition candidates for a variety of due diligence matters, including compliance with applicable regulations, laws and title records prior to acquisition. Despite these efforts, realization of any of these liabilities or deficiencies may increase our expenses, adversely affect our financial position or cause us to fail to meet our public financial reporting obligations (including as a result of difficulties in integrating different internal control systems with our existing internal control systems).

We are subject to anticorruption, anti-bribery and anti-money laundering laws and regulations.

We are subject to various anticorruption, anti-bribery and anti-money laundering laws and regulations of the United Kingdom, the United States and other jurisdictions in which we operate, that prohibit, among other things, our involvement in improper payments to certain public officials for the purpose of obtaining advantages or in transferring the proceeds of criminal activities. We have adopted a set of policies, initially put in place at the time of our AIM listing and we continue to update them as our business evolves. These policies are supported by procedures and resources designed to address both new and existing legal and regulatory requirements, including through the engagement of qualified compliance professionals and, where appropriate, external advisors. However, any errors, failures or delays in complying with anticorruption, anti-bribery and anti-money laundering laws and regulations could result in significant criminal and civil lawsuits, penalties, forfeiture of significant assets or other enforcement actions, as well as reputational harm.

Regulators may increase enforcement of these obligations, which may require us to further revise or expand our compliance program, including the procedures we use to verify the identity of our customers and to monitor our counterparties and to monitor transactions and business relationships. Regulators regularly reexamine the transaction volume thresholds at which we must obtain and keep applicable records or verify identities of customers and any change in such thresholds could result in greater costs for compliance. Costs associated with fines or enforcement actions, changes in compliance requirements or limitations on our ability to grow could harm our business and any new requirements or changes to existing requirements could impose significant costs, result in delays or disruptions to our operations, make it more difficult for us to conduct business with certain counterparties and reduce the attractiveness of our business.

Proposed changes to United States federal mining and public land law could impose, among other things, royalties and fees paid to the United States government by mining companies and royalty holders.

Periodically, members of the United States Congress have introduced bills which would supplant or alter the provisions of the General Mining Law of 1872, which governs the disposition of metallic minerals on lands owned by the federal government. Some of our mineral properties occur on unpatented mining claims located on United States federal lands. There have been recent proposals to amend the United States mining law to impose royalties or other fees on the production of select hardrock minerals, such as tungsten, from U.S. federal lands, as well as reclamation fees on production from federal and other lands.

Any such proposal, if enacted by the United States Congress, could substantially increase the cost of holding mining claims and could reduce our revenue from unpatented mining claims and on other lands in the United States. Moreover, such legislation could significantly impair the ability of our properties to develop mineral resources on unpatented mining claims. Although at this time we are not able to predict what royalties and fees may be imposed in the future, the imposition of such royalties and fees could adversely affect the potential for development of such mining claims and the economics of existing operating mines. Passage of such legislation may result in a material and adverse effect on our profitability, results of operations, financial condition and the trading price of our securities.

Land reclamation and mine closure may be burdensome and costly.

Land reclamation and mine closure requirements are generally imposed on mineral exploration companies, such as ours, which require us, among other things, to minimize the effects of land disturbance. Such requirements may include controlling the discharge of potentially dangerous effluents from a site and restoring a site’s landscape to its pre-exploration form. The actual costs of reclamation and mine closure are uncertain and planned expenditures may differ from the actual expenditures required. Therefore, the amount that we are required to spend could be materially higher than current estimates. Any additional amounts required to be spent on reclamation and mine closure may have a material adverse effect on our financial performance, financial position and results of operations and may cause us to alter our operations. In addition, we may be in the future required to maintain financial assurances, such as letters of credit, to secure reclamation obligations under certain laws and regulations. The failure to acquire, maintain or renew such financial assurances could subject us to fines and penalties or suspension of our operations. Letters of credit or other forms of financial assurance may represent only a portion of the total amount of money that may be spent on reclamation over the life of a mine’s operation. Although we include liabilities for estimated reclamation and mine closure costs in our financial statements, it may be necessary to spend more than what is projected to fund required reclamation and mine closure activities.

Transitioning to a lower-carbon economy may entail extensive policy, legal, technology and market changes to address mitigation and adaptation requirements related to climate change.

As an exploration- and development-stage company focused on tungsten and other critical minerals in the United States, we are exposed to various risks in the global transition to a lower-carbon economy across our operations, supply chain and downstream industries. These risks stem from potential government or other third-party commitments to reducing greenhouse gas emissions in the short, medium and long term, which could in the future require us to make significant investments and incur significant expenses. We may not be able to adequately adapt our business to any economic transitions geared towards limiting global warming.

As part of global value chains and with evolving policy actions around climate change, we face uncertainty and potential misalignment between national and regional governments and sectoral actions. We are exposed to significant financial burdens to comply with and adapt to new climate change regulations and standards. Our failure to make progress in these areas on a timely basis, or revisions of any initiatives and goals we may adopt, could adversely affect our businesses, access to capital and reputation.

Table of Contents

We intend to monitor identified transition risks, such as (i) potential changes in environmental or climate-related regulations that could increase permitting or compliance requirements for mining and exploration projects, (ii) evolving investor and lender expectations regarding environmental, social and governance performance, (iii) reputational risks or challenges in maintaining stakeholder support if sustainability standards are perceived as inadequate and (iv) market or supply chain developments that may require demonstrating low-carbon or responsibly sourced production to secure offtake or financing. While we currently consider our exposure to such transition risks to be limited given our focus on exploration and development of critical minerals that support the energy transition, ongoing policy, market or investor developments could, over time, increase compliance obligations, affect permitting timelines or influence access to capital.

Our holding company structure makes us dependent on the operations of our subsidiaries.

The only material asset of our holding company is all of the outstanding capital stock of our operating subsidiaries. As such, we are dependent on the earnings and cash flow of and dividends and distributions from our operating subsidiaries to pay our expenses incidental to being a public holding company and to pay any cash dividend or distribution on our securities, in each case that may be authorized by our board of directors. The ability of our subsidiaries to pay dividends or make other distributions to us is subject to applicable law and may be restricted by covenants in future debt or other financing agreements, as well as the need to retain funds for their own operations, development projects and obligations. In the event of a subsidiary’s liquidation, we may lose all or a portion of our investment in that subsidiary. Any such limitations, or the perception that such limitations may exist now or in the future, could have an adverse impact on our valuation and the price of our securities.

Concentration of future sales among a limited number of customers could expose us to significant risks.

We currently do not generate revenue from the sale of tungsten concentrate or other mineral products and do not have any binding offtake or sales agreements in place. If production begins at the Pilot Mountain and Tempiute tungsten projects, we expect that sales of our products may be concentrated among a limited number of customers, particularly in the early years of production. Dependence on a small number of customers could expose us to a variety of risks, including reduced pricing leverage, higher credit risk and the potential loss of a significant portion of our future revenues if any such customer reduces or ceases purchases from us. In addition, the loss of any major customer, delays in entering into offtake agreements or failure to secure new customers on favorable terms could materially and adversely affect our business, financial condition and results of operations. In June 2023, we entered into a non-binding letter of intent with Global Tungsten & Powders LLC, located in Towanda, Pennsylvania. The letter of intent is non-binding and does not establish any firm offtake commitments or conditions.

We have not yet secured any binding offtake agreements for our products and may be unable to do so on commercially acceptable terms or at all.

We have not entered into any binding offtake or sales agreements for tungsten or any other products that may be produced from our Pilot Mountain and Tempiute tungsten projects. Offtake agreements are often an important component in securing project financing, as they can provide revenue certainty and demonstrate market demand. If we are unable to negotiate offtake agreements on terms acceptable to us, or at all, we may face challenges in obtaining the financing required to develop and operate our projects.

In addition, without binding offtake agreements in place prior to production, we would be exposed to prevailing market prices at the time of sale, which may be volatile and could be materially lower than projected prices used in our feasibility studies. The absence of committed buyers could also result in delays in selling our production, potentially leading to reduced revenues, lower cash flows and adverse impacts on our business, financial condition and results of operations. Even if we secure offtake agreements, they may contain conditions precedent, termination rights or other provisions that could limit their effectiveness in supporting project financing or guaranteeing sales.

Risks Related to Our Securities

Any sale of a substantial number of our ordinary shares or ADSs, or the perception that such sales may occur, could adversely affect the price of our securities.

Sales of substantial amounts of our securities in the public market, or the perception that these sales could occur, could adversely affect the market price of our securities and could materially impair our ability to raise capital through equity offerings in the future. We cannot predict what effect, if any, market sales of securities held by our significant shareholders or any other shareholder or the availability of these securities for future sale will have on the market price of our securities.

The price of our securities may be volatile and may fluctuate due to factors beyond our control.

The price for our securities may vary from the market prices. The stock market in general has experienced extreme volatility that has often been unrelated to the operating performance of particular companies and the trading price of our securities may be volatile due to factors beyond our control. As a result of this volatility, if you purchase our securities, you may not be able to resell those securities at or above the purchase price. The market price of our securities may fluctuate significantly due to a variety of factors, including, among others:

These and other market and industry factors may cause the market price and demand for our securities to fluctuate substantially, regardless of our actual operating performance, which may limit or prevent investors from readily selling their securities and may otherwise negatively affect the liquidity of our securities. In addition, the stock market in general has experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these companies. In the past, when the market price of a stock has been volatile, holders of that stock have sometimes instituted securities class action litigation against the issuer. If any of the holders of our securities were to bring such a lawsuit against us, we could incur substantial costs defending the lawsuit and the attention of our senior management would be diverted from the operation of our business. Any adverse determination in litigation could also subject us to significant liabilities.

If securities or industry analysts do not publish research, or publish inaccurate or unfavorable research, about our business, the price of our securities and our trading volume could decline.

The trading market for our securities will depend in part on the research and reports that securities or industry analysts publish about us or our business. Securities and industry analysts may not publish research on us. Given our current stage of development and lack of revenue from operations, analysts may be less inclined to initiate or maintain coverage. If too few securities or industry analysts provide coverage on us, the trading price for our securities would likely be negatively affected. In the event securities or industry analysts provide coverage, if one or more of the analysts who cover us downgrade our securities or publish inaccurate or unfavorable research about our business, the price of our securities would likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, demand for our securities could decrease, which might cause the price of our securities and trading volume to decline. In addition, because our securities may be thinly traded, any such changes in coverage or sentiment could result in increased price volatility.

The dual listing of our ordinary shares and our ADSs may adversely affect the liquidity and value of our ordinary shares and ADSs.

Our ordinary shares are admitted to trading on AIM and our ADSs trade on the NYSE American. We cannot predict the effect of the dual listing on the value of our ADSs and ordinary shares. The dual listing of our ADSs and ordinary shares may dilute the liquidity of these securities in one or both markets and may adversely affect the development of an active trading market for our ADSs in the United States. The price of our ADSs could also be adversely affected by trading in our ordinary shares on AIM. In the event that we decided to cancel admission of our ordinary shares to trading on AIM, requisite consent of shareholders in a general meeting would be required pursuant to the AIM Rules for Companies, unless the London Stock Exchange agrees otherwise. We cannot predict the effect such cancellation would have on the market price of our ADSs or ordinary shares.

The NYSE American may in the future delist our ADSs from its exchange, which could limit investors’ ability to make transactions in our securities and subject us to additional trading restrictions.

Since March 2026, our ADSs have been listed on NYSE American under the symbol “GMTL”. We cannot assure you that our ADSs will continue to be listed on NYSE American. If NYSE American delists our ADSs from trading on its exchange, we could face significant material adverse consequences, including:

We are an “emerging growth company,” a “smaller reporting company” and a “foreign private issuer” and we cannot be certain if the reduced reporting requirements applicable to “emerging growth companies” and “smaller reporting companies” will make our securities less attractive to investors.

We are an “emerging growth company,” as defined in the JOBS Act. For as long as we continue to be an emerging growth company, we may take advantage of exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies, including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. As an emerging growth company, we are permitted to present only two years of financial results, as compared to three years, for comparable data reported by other public companies. We may take advantage of these exemptions until we are no longer an emerging growth company. We could be an emerging growth company for up to five years, although circumstances could cause us to lose that status earlier, including if the aggregate market value of our ADSs and ordinary shares held by non-affiliates exceeds $700 million as of any December 31 (the end of our second fiscal quarter) before that time, in which case we would no longer be an emerging growth company as of the following June 30 (our fiscal year-end). We cannot predict if investors will find our securities less attractive because we may rely on these exemptions. If some investors find our securities less attractive as a result, there may be a less active trading market for our securities, and the price of our securities may be more volatile.

We are also a “smaller reporting company” as defined in the Exchange Act. We may continue to be a smaller reporting company even after we are no longer an emerging growth company. We may take advantage of certain of the scaled disclosures available to smaller reporting companies until the fiscal year following the determination that our voting and non-voting ordinary shares held by non-affiliates is $250 million or more measured on the last business day of our second fiscal quarter, or (i) we no longer have annual revenues of less than $100 million during the most recently completed fiscal year and (ii) our voting and non-voting ordinary shares held by non-affiliates is $700 million or more measured on the last business day of our second fiscal quarter.

In addition, we report under the Exchange Act as a “foreign private issuer.” As a foreign private issuer, we are permitted to take advantage of certain provisions under the rules that allow us to follow the laws of the United Kingdom for certain corporate governance matters. Even after we no longer qualify as an emerging growth company, as long as we qualify as a foreign private issuer under the Exchange Act, we will be exempt from certain provisions of the Exchange Act that are applicable to U.S. domestic public companies. Foreign private issuers, like emerging growth companies and smaller reporting companies, also are exempt from certain more stringent executive compensation disclosure rules. Thus, if we remain a foreign private issuer, even if we no longer qualify as an emerging growth company or smaller reporting company, we will continue to be exempt from the more stringent compensation disclosures required of public companies that are neither an emerging growth company nor a foreign private issuer. We may take advantage of these exemptions until such time as we are no longer a foreign private issuer.

We qualify as a foreign private issuer and, as a result, are not subject to U.S. proxy rules and are subject to Exchange Act reporting obligations that, to some extent, are more lenient and less frequent than those of a U.S. domestic public company.

We report under the Exchange Act as a non-U.S. company with foreign private issuer status. Because we qualify as a foreign private issuer under the Exchange Act, we are exempt from certain provisions of the Exchange Act that are applicable to U.S. domestic public companies, including (i) the sections of the Exchange Act regulating the solicitation of proxies, consents or authorizations in respect of a security registered under the Exchange Act; (ii) the sections of the Exchange Act requiring insiders to file public reports of their stock ownership and trading activities and liability for insiders who profit from trades made in a short period of time; and (iii) the rules under the Exchange Act requiring the filing with the SEC of quarterly reports on Form 10-Q containing unaudited financial and other specified information, or current reports on Form 8-K, upon the occurrence of specified significant events. In addition, as a foreign private issuer with a fiscal year ending on June 30, we are not required to file our annual report on Form 20-F until 120 days after fiscal year-end, whereas U.S. domestic issuers that are accelerated filers are required to file their annual report on Form 10-K within 75 days after the end of each fiscal year. Foreign private issuers also are exempt from Regulation Fair Disclosure, aimed at preventing issuers from making selective disclosures of material information. As a result of the above, you may not have the same protections afforded to shareholders of companies that are not foreign private issuers, some investors may find our securities less attractive and there may be a less active trading market for our securities.

As a foreign private issuer, we are permitted to adopt certain home country practices in relation to corporate governance matters that differ significantly from the NYSE American corporate governance listing standards. These practices may afford less protection to shareholders than they would enjoy if we complied fully with the NYSE American corporate governance listing standards.

As a foreign private issuer listed on the NYSE American, we are subject to corporate governance listing standards. However, the NYSE American rules permit a foreign private issuer like us to follow the corporate governance practices of its home country in lieu of certain NYSE American corporate governance listing standards, provided that we disclose which requirements that we have not complied with in any year and confirm the U.K. corporate governance practices we have complied with. Certain corporate governance practices in the United Kingdom, which is our home country, may differ significantly from the NYSE American corporate governance listing standards. For example, neither the laws of the United Kingdom nor our articles of association (“Articles of Association”) have quorum requirements similar to Section 123 of the NYSE American LLC Company Guide. Although we voluntarily comply with the higher corporate governance standards of the QCA Corporate Governance Code, we could include non-independent directors as members of our nomination and remuneration committee and our independent directors would not necessarily hold regularly scheduled meetings at which only independent directors are present. We may in the future elect to follow home country practices in the United Kingdom with regard to other matters. Therefore, our shareholders may be afforded less protection than they otherwise would have under the NYSE American corporate governance listing standards applicable to U.S. domestic issuers. See Item 16.G.

We may lose our foreign private issuer status, which would then require us to comply with the Exchange Act’s domestic reporting regime and cause us to incur significant legal, accounting and other expenses.

As a foreign private issuer, we are not required to comply with all of the periodic disclosure and current reporting requirements of the Exchange Act applicable to U.S. domestic issuers. We are required to determine our status as a foreign private issuer on an annual basis at the end of our second fiscal quarter. We would cease to be a foreign private issuer, and be required to transition on January 1 of the following year, at such time as more than 50% of our outstanding voting securities are held by U.S. residents and any of the following three circumstances applies:

If we lose our status as a foreign private issuer, we would be required to comply with the Exchange Act reporting and other requirements applicable to U.S. domestic issuers, including the requirement to prepare our financial statements in accordance with U.S. generally accepted accounting principles, which are more detailed and extensive than the requirements for foreign private issuers. We may also be required to make changes in our corporate governance practices in accordance with various SEC and NYSE American rules. The regulatory and compliance costs to us under U.S. securities laws if we are required to comply with the reporting requirements applicable to a U.S. domestic issuer may be significantly higher than the cost we would incur as a foreign private issuer. As a result, we expect that a loss of foreign private issuer status would increase our legal and financial compliance costs and would make some activities highly time consuming and costly. If we lose foreign private issuer status and are unable to comply with the reporting requirements applicable to a U.S. domestic issuer by the applicable deadlines, we would not be in compliance with applicable SEC rules or the rules of the NYSE American, which could cause investors to lose confidence in our public reports and could have a material adverse effect on the trading price of our securities. We also expect that if we were required to comply with the rules and regulations applicable to U.S. domestic issuers, it would make it more difficult and expensive for us to obtain director and officer liability insurance and we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. These rules and regulations could also make it more difficult for us to attract and retain qualified members of our board of directors.

UCAM Limited (“UCAM”) beneficially owns approximately 22% of our ordinary shares. This concentration of ownership and voting power will limit your ability to influence corporate matters.

UCAM beneficially owns approximately 22% of our issued and outstanding ordinary shares. As a result, UCAM has the power to exercise significant influence over matters requiring shareholder approval, including the election of directors, amendments to our Articles of Association and certain transactions. Furthermore, we could be prevented from entering into transactions that could be beneficial to us or other shareholders, or third parties could be discouraged from making an offer or take-over bid to acquire us at a price per share or ADS that is above the then-current market price. In addition, if UCAM were to sell a substantial amount of its ordinary shares, the market price of our securities could fall. The perception that such a sale could occur may also adversely affect the market price of our securities.

Fluctuations in the exchange rate between the U.S. dollar and the pound sterling may increase the risk of holding ADSs.

The share price of ordinary shares is quoted on AIM in pounds sterling, while our ADSs trade on the NYSE American in U.S. dollars. Fluctuations in the exchange rate between the U.S. dollar and the pound sterling may result in differences between the value of our ADSs and the value of ordinary shares, which may result in heavy trading by investors seeking to exploit such differences. In addition, as a result of fluctuations in the exchange rate between the U.S. dollar and the pound sterling, the U.S. dollar equivalent of the proceeds that a holder of our ADSs would receive upon the sale in the United Kingdom of any ordinary shares withdrawn from the depositary and the U.S. dollar equivalent of any cash dividends paid in pound sterling on ordinary shares represented by our ADSs could also decline.

If we issue shares or ADSs in future financings, shareholders may experience dilution, our operations may become restricted or we may have to relinquish valuable rights, all of which could cause the price of our securities to decline.

We may from time to time issue additional shares or ADSs at a discount from the trading price of our shares or ADSs. As a result, our security holders would experience immediate dilution upon the issuance of any of our shares or ADSs at such discount. In addition, as opportunities present themselves, we may enter into financing or similar arrangements in the future, including but not limited to public and private equity offerings, debt financings and strategic partnerships and alliances. To the extent that we raise additional capital through the sale of equity, convertible debt securities or other equity-based derivative securities, our equity holders’ interests will be diluted, and the terms of the securities may include liquidation or other preferences that may be senior to the rights of our existing shareholders or holders of ADSs.

Any indebtedness we incur would result in increased payment obligations and could involve restrictive covenants, such as limitations on our ability to incur additional debt and other operating restrictions that could adversely impact our ability to conduct our business. Any debt or additional equity financing that we raise may contain terms that are not favorable to us or our equity holders. Furthermore, the issuance of additional securities, whether equity or debt, by us, or the possibility of such issuance, may cause the market price of our securities to decline and existing equity holders may not agree with our financing plans or the terms of such financings. If we raise additional funds through strategic partnerships, collaborations and alliances and licensing arrangements with third parties, we may have to relinquish valuable rights to our IP or products, or grant licenses on terms unfavorable to us.

We may from time to time distribute rights to our shareholders, including rights to acquire our securities. However, we cannot make rights available to holders in the U.S. unless we register the offer and sale of the rights and the securities to which the rights relate under the U.S. Securities Act of 1933, as amended (the “Securities Act), or an exemption from the registration requirements is available.

Because we may not pay any cash dividends on our securities in the future, capital appreciation, if any, may be your sole source of gains and you may never receive a return on your investment.

We have never declared or paid cash dividends on our ordinary shares. Under current U.K. law, a company’s accumulated realized profits, so far as not previously utilized by distribution or capitalization, must exceed its accumulated realized losses so far as not previously written off in a reduction or reorganization of capital duly made (determined by reference to our relevant (non-consolidated) accounts), before dividends can be paid. Moreover, in respect of a U.K. public company, both before and after any distribution is made, the amount of the company’s net assets must not be less than the aggregate of its called-up share capital and undistributable reserves. Therefore, we must have distributable profits and sufficient net assets before issuing a dividend. In the future, our board of directors may decide, in its discretion, whether dividends may be declared and paid. As a result, capital appreciation, if any, on our securities may be your sole source of gains, and you will suffer a loss on your investment if you are unable to sell your securities at or above the purchase price. We currently intend to retain any future earnings to finance the operation and expansion of our business, and we do not expect to declare or pay any dividends for the foreseeable future. See Item 8.A.

Securities traded on AIM may carry a higher risk than securities traded on other exchanges, which may impact the value of your investment.

Our ordinary shares are currently traded on AIM. Investment in equities traded on AIM is sometimes perceived to carry a higher risk than an investment in equities quoted on exchanges with more stringent listing requirements, such as the main market of the London Stock Exchange, NYSE or Nasdaq. This is because AIM imposes less stringent corporate governance and ongoing reporting requirements than those other exchanges. In addition, AIM requires only half-yearly, rather than quarterly, financial reporting. You should be aware that the value of our ordinary shares may be influenced by many factors, some of which may be specific to us and some of which may affect AIM-traded companies generally, including the depth and liquidity of the market, our performance, a large or small volume of trading in our ordinary shares, legislative changes and general economic, political or regulatory conditions and that the prices may be volatile and subject to extensive fluctuations. Therefore, the market price of our ordinary shares, our ADSs or of the ordinary shares underlying our ADSs, may not reflect the underlying value of our company. In addition, because AIM operates during different trading hours than the U.S. markets, discrepancies in timing may contribute to increased volatility in the trading price of our securities.

You may not be able to exercise your right to vote the ordinary shares underlying your ADSs.

ADS holders may only exercise voting rights with respect to the ordinary shares underlying their respective ADSs in accordance with the provisions of the deposit agreement.

Pursuant to the deposit agreement, the depositary will solicit voting instructions from ADS holders only if it receives notice of a shareholders’ meeting and sufficient information in a timely manner and if such solicitation is practicable and permitted under applicable law. Upon receipt of such notice, and subject to the terms of the deposit agreement and applicable law, the depositary will endeavor, insofar as practicable, to notify holders of ADSs and solicit voting instructions.

If timely notice is not received, or if solicitation is not practicable or permitted under applicable law, ADS holders may not receive voting materials or be able to instruct the depositary to vote the ordinary shares underlying their ADSs.

Holders of the ADSs will not be able to exercise the preemptive subscription rights related to the ordinary shares that they represent and may suffer dilution of their equity holding in the event of future issuances of our ordinary shares.

English law generally provides shareholders with preemptive rights when new shares are issued for cash. Shareholders’ preemptive subscription rights, in the event of issuances of ordinary shares against cash payment, may be disapplied by a special resolution of the shareholders at a general meeting of our shareholders. On December 17, 2025, our shareholders approved the exclusion of preemptive rights, with such authority expiring on the earlier of 15 months from the date of approval of that exclusion or the conclusion of our next annual general meeting. Such exclusion will need to be renewed upon expiration (i.e., on the earlier of the date that is 15 months after December 17, 2025, or the conclusion of our next annual general meeting) to remain effective, but may be sought more frequently for additional five-year terms (or any shorter period). The absence of preemptive rights for existing equity holders may cause dilution to such holders.

Table of Contents

Furthermore, ADS holders would not be entitled, even if such rights accrued to our shareholders in any given instance, to receive such preemptive subscription rights related to the ordinary shares that they represent. Under the deposit agreement, the depositary will not make rights available to ADS holders unless the rights and any related securities are registered under the Securities Act or exempt from registration under the Securities Act. The depositary may attempt to sell any such subscription rights relating to the ordinary shares underlying the ADSs and distribute the net proceeds of any such sale to ADS holders pro rata, after deduction of applicable fees, taxes and expenses. However, the depositary is under no obligation to make any such sale. If the depositary determines that the sale of rights is unlawful or not reasonably practicable, it will allow the rights to lapse, in which case ADS holders will receive no value for these rights.

Further, if we offer holders of our ordinary shares the option to receive dividends in either cash or ordinary shares, under the deposit agreement, ADS holders will not be permitted to elect to receive dividends in ordinary shares or cash, but will receive whichever option we provide as a default to shareholders who fail to make such an election.

Purchasers of ADSs may not receive distributions on our ordinary shares in the form of ADSs or any value for them if it is illegal or impractical to make them available to holders of ADSs.

The depositary for our ADSs has agreed to pay to purchasers of our ADSs the cash dividends or other distributions it or the custodian receives on our ordinary shares or other deposited securities after deducting its fees and expenses. Purchasers of our ADSs will receive these distributions in proportion to the number of our ordinary shares their ADSs represent. However, in accordance with the limitations set forth in the deposit agreement, it may be unlawful or impractical to make a distribution available to holders of ADSs. We have no obligation to take any other action to permit the distribution of our ADSs, ordinary shares, rights or anything else to holders of our ADSs. This means that purchasers of ADSs may not receive the distributions we make on our ordinary shares or any value from them if it is unlawful or impractical to make them available to them. These restrictions may have a material adverse effect on the value of a purchaser’s ADSs.

You may be subject to limitations on transfers of the ADSs.

The ADSs are transferable on the books of the depositary. However, the depositary may close its transfer books at any time or from time to time when it deems expedient in connection with the performance of its duties. In addition, the depositary may refuse to deliver, transfer or register transfers of ADSs generally when our books or the books of the depositary are closed, or at any time if we or the depositary deems it advisable to do so because of any requirement of law or of any government or governmental body, or under any provision of the deposit agreement, or for any other reason, in accordance with the terms of the deposit agreement.

ADS holders may not be entitled to a jury trial with respect to claims arising under the deposit agreement, which could result in less favorable outcomes to the plaintiff(s) in any such action.

The deposit agreement governing the ADSs representing our ordinary shares provides that, to the fullest extent permitted by applicable law, holders and beneficial owners of ADSs irrevocably waive the right to a jury trial of any claim that they may have against us or the depositary arising from or relating to our ordinary shares, our ADSs or the deposit agreement, including any claim under the U.S. federal securities laws. The waiver continues to apply to claims that arise during the period when a holder holds the ADSs, even if the ADS holder subsequently withdraws the underlying ordinary shares.

However, you will not be deemed, by agreeing to the terms of the deposit agreement, to have waived our or the depositary’s compliance with U.S. federal securities laws and the rules and regulations promulgated thereunder. In fact, you cannot waive our or the depositary’s compliance with U.S. federal securities laws and the rules and regulations promulgated thereunder. If we or the depositary opposed a demand for jury trial relying on above-mentioned jury trial waiver, it is up to the court to determine whether such waiver was enforceable considering the facts and circumstances of that case in accordance with the applicable state and federal law.

Table of Contents

If this jury trial waiver provision is prohibited by applicable law, an action could nevertheless proceed under the terms of the deposit agreement with a jury trial. To our knowledge, the enforceability of a jury trial waiver under the federal securities laws has not been finally adjudicated by a federal court or by the United States Supreme Court. Nonetheless, we believe that a jury trial waiver provision is generally enforceable under the laws of the State of New York, which govern the deposit agreement, by a federal or state court in the City of New York. In determining whether to enforce a jury trial waiver provision, New York courts will consider whether the visibility of the jury trial waiver provision within the agreement is sufficiently prominent such that a party has knowingly waived any right to trial by jury. We believe that this is the case with respect to the deposit agreement and the ADSs. In addition, New York courts will not enforce a jury trial waiver provision in order to bar a viable setoff or counterclaim sounding in fraud or one which is based upon a creditor’s negligence in failing to liquidate collateral upon a guarantor’s demand, or in the case of an intentional tort claim, none of which we believe are applicable in the case of the deposit agreement or the ADSs. If you or any other holders or beneficial owners of ADSs bring a claim against us or the depositary relating to the matters arising under the deposit agreement or our ADSs, including claims under federal securities laws, you or such other holder or beneficial owner may not have the right to a jury trial regarding such claims, which may limit and discourage lawsuits against us or the depositary. If a lawsuit is brought against us or the depositary according to the deposit agreement, it may be heard only by a judge or justice of the applicable trial court, which would be conducted according to different civil procedures and may have different outcomes compared to that of a jury trial, including results that could be less favorable to the plaintiff(s) in any such action.

Moreover, as the jury trial waiver relates to claims arising out of or relating to the ADSs or the deposit agreement, we believe that, as a matter of construction of the clause, the waiver would likely continue to apply to ADS holders who withdraw the ordinary shares from the ADS facility with respect to claims arising before the cancellation of the ADSs and the withdrawal of the ordinary shares, and the waiver would most likely not apply to ADS holders who subsequently withdraw the ordinary shares represented by ADSs from the ADS facility with respect to claims arising after the withdrawal. However, to our knowledge, there has been no case law on the applicability of the jury trial waiver to ADS holders who withdraw the ordinary shares represented by the ADSs from the ADS facility.

ADS holders have limited choice of forum, which could limit your ability to obtain a favorable judicial forum for complaints against us, the depositary or our respective directors, officers or employees.

The deposit agreement governing our ADSs provides that the deposit agreement and the ADSs will be interpreted in accordance with the laws of the State of New York. Under the deposit agreement, by holding or owning an American Depositary Receipt (“ADR”) or ADS or an interest therein, ADS holders and beneficial owners irrevocably agree that any legal suit, action or proceeding against or involving ADS holders or beneficial owners brought by us or the depositary, arising out of or based upon the deposit agreement, the ADSs, the ADRs or the transactions contemplated therein or thereby, may be instituted in a state or federal court in New York, New York, and by holding or owning an ADR or ADS or an interest therein each irrevocably waives any objection that it may now or hereafter have to the laying of venue of any such proceeding, and irrevocably submits to the non-exclusive jurisdiction of such courts in any such suit, action or proceeding.

Under the deposit agreement, by holding or owning an ADR or ADS or an interest therein, ADS holders and beneficial owners each irrevocably agree that any legal suit, action or proceeding against or involving the depositary and/or us brought by ADS holders or beneficial owners, arising out of or based upon the deposit agreement, the ADSs, the ADRs or the transactions contemplated therein or thereby, including, without limitation, claims under the Securities Act, may be instituted only in the United States District Court for the Southern District of New York (or in the state courts of New York County in New York if either (i) the United States District Court for the Southern District of New York lacks subject matter jurisdiction over a particular dispute or (ii) the designation of the United States District Court for the Southern District of New York as the exclusive forum for any particular dispute is, or becomes, invalid, illegal or unenforceable).

These choice of forum provisions may increase your cost and limit your ability to bring a claim in a judicial forum that you find favorable for disputes with us, the depositary or our and the depositary’s respective directors, officers or employees, which may discourage such lawsuits against us, the depositary and our and the depositary’s respective directors, officers or employees. However, it is possible that a court could find such choice of forum provisions to be inapplicable or unenforceable. The enforceability of similar choice of forum provisions has been challenged in legal proceedings.

Table of Contents

Under the deposit agreement, the depositary may bring actions against us arising out of or based upon the deposit agreement, the ADSs, the ADRs or the transactions contemplated thereby in the state or federal courts located in New York, New York or, at the depositary’s option, in any competent court in England and Wales. Notwithstanding the foregoing, ADS holders will not be deemed to have waived compliance with the federal securities laws and the rules and regulations promulgated thereunder. Claims arising under the Securities Act may be brought in federal or state courts as provided in Section 22 of the Securities Act, and claims arising under the Exchange Act are subject to the exclusive jurisdiction of the federal courts pursuant to Section 27 of the Exchange Act.

The rights of our shareholders may differ from the rights typically offered to shareholders of a U.S. corporation.

We are incorporated under English law. The rights of holders of ordinary shares and, therefore, certain of the rights of holders of ADSs, are governed by English law, including the provisions of the U.K. Companies Act 2006 (as amended) (the “Companies Act 2006”) and by our Articles of Association. These rights differ in certain respects from the rights of shareholders in typical U.S. corporations. For further information, please see Item 10.B.

We are entitled to amend the deposit agreement and to change the rights of ADS holders under the terms of such agreement, or to terminate the deposit agreement, without the prior consent of the ADS holders.

We are entitled to amend the deposit agreement and to change the rights of the ADS holders under the terms of such agreement without the prior consent of the ADS holders. We and the depositary may agree to amend the deposit agreement in any way we decide is necessary or advantageous to us. Amendments may reflect, among other things, operational changes in the ADS program, legal developments affecting ADSs or changes in the terms of our business relationship with the depositary. In the event that the terms of an amendment impose or increase any fees on a per ADS basis, charges or expenses (other than stock transfer or other taxes and other governmental charges, transfer or registration fees, the transaction fee per cancellation request (including any cancellation request made through SWIFT, facsimile transmission or any other method of communication)), applicable delivery expenses or other such fees, charges or expenses, or that would otherwise prejudice any substantial existing right of the ADS holders, such amendment will not become effective as to outstanding ADSs until the expiration of 30 days after notice of that amendment has been disseminated to the ADS holders; but no prior consent of the ADS holders is required under the deposit agreement. Furthermore, we may decide to terminate the ADS facility at any time for any reason. For example, terminations may occur when the ADSs are delisted from the stock exchange in the United States on which the ADSs are listed and we do not list the ADSs on another stock exchange in the United States, nor is there a symbol available for over-the-counter trading of the ADSs in the United States. If the ADS facility will terminate, ADS holders will receive at least 30 days’ prior notice, but no prior consent is required from them. Under the circumstances that we decide to make an amendment to the deposit agreement that is disadvantageous to ADS holders or terminate the deposit agreement, the ADS holders may choose to sell their ADSs or surrender their ADSs and become direct holders of the underlying ordinary shares, but will have no right to any compensation whatsoever.

Claims of U.S. civil liabilities may not be enforceable against us.

We are incorporated under English law. Substantially all of our assets are located outside the United States. The majority of our management and board of directors reside outside the United States. As a result, it may not be possible for investors to effect service of process within the United States upon such persons or to enforce judgments obtained in U.S. courts against them or us, including judgments predicated upon the civil liability provisions of the U.S. federal securities laws.

The United States and the United Kingdom do not currently have a treaty providing for recognition and enforcement of judgments (other than arbitration awards) in civil and commercial matters. Consequently, a final judgment for payment given by a court in the United States, whether or not predicated solely upon U.S. securities laws, would not automatically be recognized or enforceable in the United Kingdom. In addition, uncertainty exists as to whether U.K. courts would entertain original actions brought in the United Kingdom against us or our directors or senior management predicated upon the securities laws of the United States or any state in the United States. Any final and conclusive monetary judgment for a definite sum obtained against us in U.S. courts would be treated by the courts of the United Kingdom as a cause of action in itself and sued upon as a debt at common law so that no retrial of the issues would be necessary, provided that certain requirements are met. Whether these requirements are met in respect of a judgment based upon the civil liability provisions of the U.S. securities laws, including whether the award of monetary damages under such laws would constitute a penalty, is an issue for the court making such decision. If an English court gives judgment for the sum payable under a U.S. judgment, the English judgment will be enforceable by methods generally available for this purpose. These methods generally permit the English court discretion to prescribe the manner of enforcement.

Table of Contents

As a result, U.S. investors may not be able to enforce against us or our executive officers, board of directors or certain experts named herein who are residents of the United Kingdom or countries other than the United States any judgments obtained in U.S. courts in civil and commercial matters, including judgments under the U.S. federal securities laws.

Our passive foreign investment company (“PFIC”) status for any taxable year is subject to uncertainty. If we are a PFIC for any taxable year during which a U.S. investor owns our ADSs or ordinary shares, the investor will generally be subject to adverse U.S. federal income tax consequences.

In general, a non-U.S. corporation will be a PFIC for U.S. federal income tax purposes for any taxable year in which (i) 75% or more of its gross income consists of passive income, or (ii) 50% or more of the average value of its assets (generally determined on a quarterly basis) consist of assets that produce, or are held for the production of, passive income. For purposes of the above calculations, a non-U.S. corporation that directly or indirectly owns at least 25% by value of the ordinary shares of another corporation is generally treated as if it held its proportionate share of the assets of the other corporation and received directly its proportionate share of the income of the other corporation. Passive income generally includes interest, dividends, certain rents and royalties, net gains from assets that produce passive income and net gains from transactions in commodities, with an exception for certain active business commodities gains (the “Commodities Exception”). Cash is generally a passive asset for PFIC purposes. The value of a company’s goodwill and other intangible assets is active under the PFIC rules to the extent attributable to activities that produce active income.

Based on the composition of our income (including from governmental grants, which are not shown on our income statements but we treat as income for U.S. federal income tax purposes) and the estimated value of our assets (including the value of our goodwill and other intangible assets that are not shown on our balance sheet), we believe that we were not a PFIC for our taxable year ended June 30, 2026. However, our PFIC status for any taxable year is an annual factual determination that can be made only after the end of that year and depends on the composition of our income and assets and the value of our assets from time to time. Prior to our mines becoming operational, our gross income may consist primarily of government grants and consultancy and technical service fees (which we believe are likely to be treated as active income to the extent included in our income for U.S. federal income tax purposes) and interest (which is passive income). However, the treatment of the government grants as our taxable income and the classification of such income as active for purposes of the PFIC rules is not entirely clear. Moreover, the receipt of government grants and consultancy and technical service fees is non-recurring in nature, and the government grants are subject to various conditions. In addition, the amount of our gross income and the timing of its inclusion for U.S. federal income tax purposes may differ from their accounting treatment (and thus may not correspond to the amounts shown on our income statements), and the Internal Revenue Service may disagree with the timing or amount of income that we or an investor may consider as earned for any taxable year. Therefore, there can be no assurance as to the amount of any non-passive income earned by us for any taxable year. It is possible that our non-passive gross income (if any) for any taxable year will constitute 25% or less of our total gross income, in which case we will be a PFIC for such year. Once we commence earning income from sales of minerals in future taxable years, our PFIC status for any taxable year may depend upon the extent to which our income will be treated as active under the Commodities Exception, the application of which may not be entirely clear in all cases.

Furthermore, because we hold a significant amount of cash, our PFIC status for any taxable year depends in part on the value of our goodwill and other intangible assets. If the value of our goodwill and other intangible assets for any taxable year is determined by reference to our market capitalization (which has been, and may continue to be, volatile, particularly prior to the commencement of sales of minerals from our mines), the risk of us being or becoming a PFIC for any taxable year will increase if our market capitalization fluctuates or declines significantly.

If we are a PFIC for any taxable year during which a U.S. investor owns our ADSs or ordinary shares, the U.S. investor generally will be subject to adverse U.S. federal income tax consequences, including increased tax liability on disposition gains and “excess distributions,” and additional reporting requirements. This will generally continue to be the case even if we ceased to be a PFIC in a later taxable year, unless certain elections are made. See “Taxation—Material U.S. Federal Income Tax Considerations” below.

Item 4. Information on the Company

A. History and development of the company

Guardian was incorporated as a private limited company with the legal name Golden Metal Resources Limited under the laws of England and Wales on April 22, 2021, with the company number 13351178. On March 8, 2022, Guardian re-registered as a public limited company, and on July 4, 2024, changed the company name to Guardian Metal Resources PLC. The address of Guardian’s registered office is c/o Orana Corporate LLP, 25 Eccleston Place, London SW1W 9NF, United Kingdom, and its telephone number is +(44) 20 7078 8496. The Company’s agent for service of process in the United States is Golden Metal Resources, LLC, address 3800 Howard Hughes Parkway STE 1000, Las Vegas, Nevada 89169, United States of America. The Company was formed to hold and advance the Nevada mineral exploration assets previously held by Power Metal Resources PLC.

On May 10, 2023, the Company’s ordinary shares were admitted to trading on the AIM market of the London Stock Exchange under the ticker “GMET”. On October 13, 2023, the Company also obtained a cross-listing on the U.S. OTC market to broaden its investor base. On March 24, 2026, the Company completed its IPO on NYSE American, in which it issued and sold an aggregate of 5,055,953 ADSs, representing 25,279,765 ordinary shares, at a public offering price of $13.50 per ADS, including ADSs sold pursuant to the exercise of the underwriters’ over-allotment option. Since March 2026, the Company’s ADSs have been listed on NYSE American under the symbol “GMTL”.

Since incorporation, Guardian has progressively expanded its portfolio of mineral assets in Nevada. At the time of admission to AIM in May 2023, the Company held four projects: Pilot Mountain (tungsten-copper-silver-zinc), Garfield (gold-silver-copper), Stonewall (gold-silver) and an earn-in option at Golconda (gold). In July 2023, the portfolio was expanded through the staking of mineral claims over the Kibby Basin lithium project, bringing the total to five projects by 2024. In 2025, the Company further broadened its asset base by entering into a lease-option agreement to acquire Tempiute project, increasing the portfolio to six projects. In 2026, the portfolio was expanded through the staking of mineral claims over the Cinch tungsten-silver project, Pilot North tungsten-copper-silver project and White Elephant tungsten project, bringing the total to nine projects.

In January 2025, we completed the option to purchase the historical Tempiute (also known as the Emerson) tungsten mine in Nevada, following a letter of intent signed on October 31, 2024 and a definitive agreement dated January 25, 2025. Since completion of that acquisition, we have completed an initial exploratory drilling program. Drilling is continuing at Tempiute, and the Company has set an objective for 2027 of an initial resource assessment. There can be no assurance that a resource from such early-stage drilling will be established at Tempiute. During the fiscal year ended June 30, 2026, we also advanced pre-feasibility study workstreams at our Pilot Mountain project, including resource and geotechnical drilling, baseline environmental studies and early permitting activities.

In July 2025, we raised approximately £15.6 million (approximately $21.0 million) in aggregate gross proceeds through a private placement of 25,945,000 ordinary shares and received a $6.2 million Defense Production Act Title III award from the U.S. Department of War in support of the accelerated exploration and development of the Pilot Mountain project. In March 2026, we completed our U.S. initial public offering of 5,055,953 ADSs (representing 25,279,765 ordinary shares), including ADSs sold pursuant to the underwriters’ exercise of their option to purchase additional ADSs, at a public offering price of $13.50 per ADS, for aggregate gross proceeds of approximately $68.3 million, and our ADSs were listed on the NYSE American under the symbol “GMTL”. See Item 9.A “The Offer and Listing—Offer and listing details” and Item 14.E “Material Modifications to the Rights of Security Holders and Use of Proceeds—Use of proceeds.”

In May 2026, we announced the identification of an approximately 550-acre footprint of historical tungsten-enriched mine tailings at Tempiute and the staking of 193 additional mining claims, increasing the overall Tempiute project footprint by over 375%. In June 2026, we announced the discovery of the Tremor zone, a newly identified tungsten-mineralized skarn zone at Pilot Mountain. On June 17, 2026, we acquired property and water rights from Lincoln Estates Group LLC for a purchase price of $1.3 million in cash, comprising approximately 841 acres of real property and 2,540 acre-feet per annum of water rights located less than 10 miles from Tempiute. On June 30, 2026, we announced the results of the PFS for Pilot Mountain. See Item 4.B “—Mining Properties.”

Table of Contents

On June 26, 2026, Tempiute Inc. was incorporated as an indirect wholly owned subsidiary of the Company, held through Golden Metal Resources, LLC. As part of an internal corporate reorganization, with effect from 11:59:59 p.m. (Pacific time) on June 30, 2026, BFM Resources Inc. was merged into Pilot Metals Inc., with Pilot Metals Inc. as the surviving entity, and Pilot Metals Inc. became a wholly owned subsidiary of Golden Metal Resources, LLC. In connection with the reorganization, Guardian Gold Ltd., our wholly owned subsidiary incorporated in England and Wales, changed its name to Guardian Exploration Ltd, and our interests in the Garfield, Golconda, Kibby Basin, Stonewall, Cinch, Pilot North and White Elephant projects were transferred from Golden Metal Resources, LLC to Guardian Exploration Inc., a newly incorporated Nevada corporation wholly owned by Guardian Exploration Ltd. Following the end of fiscal year 2026, on July 7, 2026, we entered into a strategic partnership with the Montana Mining Association, advanced in conjunction with Montana Technological University and the Army Research Laboratory, under which we expect to supply an initial approximately 250-400 tonnes of stockpiled legacy ore from Tempiute for trial processing in Philipsburg, Montana. On July 14, 2026, we announced exploration results across our non-core portfolio, including at the newly staked Cinch, Pilot North and White Elephant. See Item 4.B “—Mining Properties” and Item 8.B “Financial Information—Significant changes.”

On September 10, 2026, we announced that we had entered into a collaboration agreement on August 25, 2026, with Oritain Global Limited (“Oritain”), a global leader in forensic origin verification, to facilitate development of a database of origin fingerprints for tungsten, intended to support the development of provenance verification for tungsten for governments, industry and end consumers.

On September 14, 2026, we announced exploration results and related technical information from the Tremor zone and the Good Hope zone at Pilot Mountain, as described in Item 4.B “Business Overview—Exploration results subsequent to fiscal year end: Tremor zone and Good Hope zone.”

Capital expenditure

For capital expenditures (including current capital expenditures), reference is made to Note 9 to the Consolidated Financial Statements included in the Annual Report 2026.

During the fiscal year ended June 30, 2026, our capital expenditures comprised capitalized exploration and evaluation expenditures of approximately $27.9 million, all of which related to our mineral projects in Nevada, United States, including approximately $18.9 million at Pilot Mountain and approximately $9.0 million at Tempiute. These capital expenditures were financed from internal resources, being cash on hand, including the net proceeds of our July 2025 private placement and our March 2026 initial public offering and amounts received under the DoW award; we did not incur indebtedness to finance capital expenditures. No principal divestitures are currently in progress.

For the fiscal years ended June 30, 2025 and 2024, our capital expenditures comprised capitalized exploration and evaluation expenditures of approximately $8.1 million and $1.5 million, respectively, in each case relating to our mineral projects in Nevada and financed from cash on hand. On June 17, 2026, we acquired property and water rights from Lincoln Estates Group LLC for $1.3 million in cash, as described above. Our principal capital expenditures currently in progress comprise the continued advancement of Pilot Mountain toward a feasibility study and the ongoing drilling program at Tempiute, for which our board has approved budgets of approximately $28.0 million and $9.6 million, respectively, for work through June 30, 2027, all of which relate to our projects in Nevada and which we expect to fund from available cash resources. The board of directors may approve additional funding beyond the budgets based on cash availability, financing opportunities or other potential funding sources.

No significant divestments took place in the fiscal period 2023-2026.

Public takeover offers

No such offers occurred during fiscal year 2026 or have occurred in fiscal year 2027 to date.

B. Business overview

We are a U.S.-focused exploration- and development-stage critical minerals company with a portfolio of tungsten and polymetallic projects located in the State of Nevada. Our principal tungsten asset is the Pilot Mountain project, followed by the Tempiute project, which are both situated in historic tungsten districts with well-known occurrences of scheelite-bearing skarn mineralization that have seen prior tungsten mining activity by third parties. In addition, we hold early-stage copper, gold, silver and lithium exploration properties, which we believe provide optionality and exposure to broader critical-minerals thematic trends.

Tungsten is designated as a critical mineral in the United States and the European Union. A diversified, domestic supply of tungsten in the United States is increasingly viewed as strategically important due to concentrated global production and recent export controls in China, which accounted for approximately 84% of global output in 2024, according to industry sources. Over the past year, we have advanced our flagship Pilot Mountain project through a drilling program that returned tungsten, silver and zinc intercepts, and have continued geological, metallurgical, environmental and engineering work to support future development planning. The results of the PFS for Pilot Mountain were announced on June 30, 2026, and the project moved into the definitive feasibility stage. The PFS included the initial declaration of reserves at Pilot Mountain.

Operations

We do not currently operate producing mines and have not generated revenue from mineral production. Our activities are focused on the exploration, technical evaluation and development of our mineral properties, including the advancement of the Pilot Mountain project following completion of the PFS, and on preparing the groundwork for future permitting and development decisions. Our projects are located within established mining jurisdictions in Nevada, where mining regulations and permitting processes have historically been favorable to the sector.

Our operational activities include exploration and resource definition drilling, environmental baseline studies and engineering studies. These programs are conducted through our U.S. subsidiaries and supported by independent consultants, including qualified persons as defined under Subpart 1300 of Regulation S-K.

In addition to ongoing work at Pilot Mountain and Tempiute, we manage a portfolio of earlier-stage exploration projects, including the Garfield gold-silver-copper project, the Golconda gold project, the Kibby Basin lithium project, the Stonewall gold-silver project, the Cinch tungsten-silver project, the Pilot North tungsten-copper-silver project and the White Elephant tungsten project. Together, we believe these properties provide a pipeline of exploration opportunities across multiple commodities within Nevada, a well-established mining jurisdiction. We continue to evaluate opportunities to advance our assets, maintain regulatory compliance and meet the technical and environmental requirements associated with future project development.

Principal markets

Our strategy is to supply tungsten and other critical minerals into U.S. and allied supply chains, particularly those supporting defense, energy transition, nuclear fusion and high-technology industries. Tungsten has been designated as a critical mineral by the U.S. government due to its importance in defense applications and limited non-Chinese supply sources. Should we advance our projects to production, we expect to market products primarily to customers in the U.S.

Seasonality

Our exploration activities may be subject to seasonal constraints, including winter weather conditions in Nevada that can affect access and drilling schedules. However, Nevada’s climate generally allows year-round exploration. We do not expect seasonality to materially affect our business.

Raw materials/tungsten

Tungsten is our primary focus commodity. Tungsten is valued for its high melting point, strength and density, making it critical for defense, aerospace, nuclear and industrial applications. Global supply is dominated by China, which has historically accounted for more than 80% of production and refined supply, according to industry sources. U.S. policy emphasizes the need for domestic and allied sources of tungsten to reduce reliance on Chinese supply. We believe Pilot Mountain, our flagship project, is one of the largest known undeveloped tungsten deposits in the U.S. and positions us to potentially become a key domestic supplier.

Nevada is generally regarded as a favorable jurisdiction for mineral exploration and development. Nevada also has a long history of mineral development, with well over a century of gold and silver mining activity, and remains one of the most established mining jurisdictions in the United States. Such assessments are generally based on factors such as regulatory transparency, geological potential and permitting frameworks and should not be interpreted as assessments of, or guarantees of, permitting or regulatory outcomes for our projects.

Marketing channels

We do not currently generate revenue and have no commercial sales. Should our projects advance to production, we expect to market tungsten concentrate and any by-products to refiners, processors and industrial end-users in the United States and other jurisdictions seeking secure sources of critical minerals. We have engaged in preliminary, non-binding discussions with certain potential customers, including Global Tungsten & Powders LLC, regarding the possible future supply of tungsten concentrate; however, these discussions are at an early stage, are non-binding and may not result in any definitive agreement or commercial arrangement. There can be no assurance that any such discussions will lead to production, sales or revenue.

For our gold and copper assets, should they be developed, we would expect to sell gold doré to refiners and copper concentrate to commodity traders or smelters, consistent with industry practice. We do not expect to engage in direct consumer marketing. Our distribution strategy will therefore focus on strategic and industrial counterparties positioned within U.S. and Western supply chains.

Competitive environment

The mineral exploration and development business is highly competitive. We compete with other exploration companies for the acquisition of prospective mineral properties, technical expertise and access to capital. Many of these companies currently have greater resources than we do to be able to identify and evaluate prospective mineral projects or titles and often have greater financial resources to be able to pursue their acquisition. In addition, we also encounter competition for the hiring of key personnel whether as employees, consultants or other service providers. The mineral exploration and mining industry is currently facing a shortage of experienced mining professionals. Moreover, the demand for exploration equipment (including drilling rigs), technical consultants and assay labs is very high and such personnel and services may not be available, or if they are, at costs that are greater than expected resulting in an increase in our costs. This competition affects us by increasing the time and cost to conduct exploration activities.

The tungsten market is characterized by significant supply concentration and limited new project development. According to industry sources, China accounts for approximately 80%-85% of global primary tungsten supply, although its share is forecast to decline over the long term as ore grades fall, production costs increase and government mining quotas tighten. Chinese exports of controlled tungsten products such as APT and tungsten oxides continue to affect the market. According to industry sources, in January and February 2026, China exported approximately 1,805t of tungsten products, a 28% decrease compared to the same period in 2025.

Demand for tungsten is expected to grow broadly in line with global GDP, with the defense sector representing the fastest-growing end-use segment as military spending increases across NATO member states and other jurisdictions. Global tungsten markets are currently tight, with concentrate prices near record levels, driven by constrained Chinese supply, growing demand from defense applications and increased geopolitical uncertainty, including China’s 2025 export controls on APT, tungsten oxides, carbides and certain alloys.

We believe our Nevada tungsten projects, particularly Pilot Mountain and Tempiute, are positioned to benefit from the increasing strategic importance of non-Chinese tungsten supply, given their location in a stable jurisdiction with proximity to U.S. and Western end-markets. However, we face competition from established global producers and from new and restarted tungsten projects, including those in Kazakhstan, South Korea, Spain, the United Kingdom, Canada and Australia. Our ability to maintain a competitive position will depend on our success in advancing our projects to production, controlling costs and securing long-term offtake and customer relationships.

Customers and contracts

We are an exploration- and development-stage company and currently do not generate revenue from mineral production or sales. We have not entered into any binding offtake agreements. In June 2023, we entered into a non-binding letter of intent with Global Tungsten & Powders LLC in respect of a potential future offtake agreement for tungsten concentrate from our Pilot Mountain project, subject to the completion of technical and legal due diligence; in light of the increase in tungsten prices since the letter of intent was entered into, we expect that its commercial terms would need to be updated in connection with any definitive agreement. We may from time to time enter into additional memoranda of understanding or option agreements with strategic or industrial partners.

Suppliers

As an exploration- and development-stage company, we do not maintain in-house drilling or laboratory operations and are therefore reliant on third-party contractors and service providers to carry out our exploration programs. These contractors include drilling companies, geophysical survey providers, assay laboratories, environmental consultants and other technical specialists, all of which are widely available in Nevada and surrounding states. While we do not believe we are materially dependent on any single supplier, the success and cost-efficiency of our programs depend on the continued availability of high-quality contractors and exploration services.

From time to time, the exploration sector experiences increased demand for drilling rigs, assay turnaround and skilled labor, particularly during periods of elevated commodity prices. Such conditions may increase costs or cause delays to our planned work programs. In addition, the sourcing of certain consumables, such as fuel, explosives and geochemical reagents, may be subject to market price volatility and supply chain constraints.

We intend to mitigate these risks by maintaining relationships with multiple contractors, engaging well-established providers and planning our work programs to allow flexibility in scheduling. For our tungsten and lithium projects, we may also require specialized metallurgical and technical services and we believe Nevada offers sufficient expertise to support our exploration and future development activities.

Products

We have not commenced commercial production. Our efforts are focused on identifying and defining mineral resources of tungsten in Nevada and the subsequent development of such resources. Our Pilot Mountain and Tempiute projects are tungsten-dominant, with potential by-products of copper, silver, zinc and gallium. We also hold early-stage projects prospective for tungsten (White Elephant), tungsten-copper-silver (Pilot North), tungsten-silver (Cinch), gold-silver-copper (Garfield), gold (Golconda), lithium (Kibby Basin) and gold-silver (Stonewall).

Dependence on patents, licenses, contracts and processes

We do not rely on patents or proprietary technologies in our business. Title to our projects is held through either unpatented, placer or mill site claims administered by the BLM as well as patented claims. The unpatented, mill site and placer claims are subject to annual maintenance fees and compliance with applicable mining laws and regulations. We are also party to certain option agreements, including our earn-in right at the Golconda project and the lease-option agreement to acquire the Tempiute tungsten project, which require us to make staged payments in order to maintain our interests.

We do not currently have any binding offtake agreements in place. We have, however, entered into non-binding arrangements, including a letter of intent with Global Tungsten & Powders LLC regarding potential future sales of tungsten concentrate from Pilot Mountain. We and Global Tungsten & Powders LLC have also engaged in preliminary discussions regarding potential cooperation areas relating to future supply chain development initiatives in the United States and allied jurisdictions. These discussions are exploratory in nature, do not create any binding commitments for either party and may not result in any formal agreements. We engage in preliminary discussions regarding other offtake agreements from time to time. Any future offtake, cooperation or supply-chain arrangements would depend on, among other factors, the advancement of our projects, market conditions, technical due-diligence outcomes and the negotiation of mutually acceptable terms. We also signed a memorandum of understanding with Oxford Sigma Limited in respect of potential tungsten applications in the fusion energy industry. These arrangements do not create enforceable obligations and may not result in binding contracts. Our ability to finance and develop our projects may in the future depend on securing binding offtake agreements with refiners, processors or end-users of tungsten and other commodities, and there can be no assurance that such agreements will be entered into on commercially acceptable terms or at all.

Intellectual property

We rely on a combination of confidentiality as well as employee and third-party non-disclosure agreements, to establish and protect our intellectual property rights. As of June 30, 2026, we did not own any patents or copyrights and we have not registered or otherwise protected any trademarks. We own the domain names covering our brand “Guardian Metal Resources” and related logos and we maintain domain names, including “www.guardianmetalresources.com.”

Regulation

The exploration and development of a mining prospect are subject to regulation by a number of federal and state government authorities. Mineral exploration and development on federal lands are principally governed by the General Mining Law of 1872, as amended, which authorizes U.S. citizens and companies to locate mining claims on federal lands open to mineral entry. All of our Nevada projects, including Pilot Mountain, Tempiute, Garfield, Golconda, Kibby Basin, Stonewall, Pilot North, White Elephant and Cinch, include unpatented lode, mill site and/or placer mining claims administered by the BLM. To maintain these claims in good standing, we must comply with BLM regulations, including annual maintenance fees, performance of assessment work and submission of required filings. Tempiute, in addition to unpatented BLM mining, mill site and placer claims, includes certain patented (private) mining claims.

Under BLM regulations, low-impact activities such as surface mapping and sampling qualify as “casual use” and generally do not require prior approval, whereas mechanized exploration activities, including road construction and drilling, require either a notice-level filing or an approved PoO, depending on the level of proposed surface disturbance. Notice-level filings generally cover disturbance of up to approximately five acres; larger programs require a PoO, which is subject to review under the National Environmental Policy Act (“NEPA”), including preparation of an environmental assessment and, in some cases, an environmental impact statement.

At the state level, the NDEP regulates water use, air quality, mine reclamation and closure and management of hazardous materials. Nevada law requires operators to prepare and maintain approved reclamation plans and to post financial assurance in the form of reclamation bonds to cover closure obligations. Additional state and local permits may be required for drilling, water rights and the use or storage of explosives. Compliance with these requirements is a condition for continuing exploration and for advancing projects toward development. The failure to comply with the regulations and terms of permits and licenses may result in fines or other penalties or in revocation of a permit or license or loss of a prospect.

As a public limited company incorporated in the United Kingdom, we are also subject to the Companies Act 2006, the AIM Rules for Companies, U.K. Market Abuse Regulation (Regulation (EU) 596/2014), the U.K. City Code on Takeovers and Mergers (the “U.K. Takeover Code”) and certain provisions of the Disclosure Guidance and Transparency Rules of the U.K. Financial Conduct Authority (“DTRs”) and other applicable securities regulations including U.S. securities law requirements.

Environmental, health and safety matters

Exploration activities in Nevada are subject to federal and state environmental, health and safety requirements. These laws and regulations address, among other matters, land use and reclamation, air emissions, water use and discharge, protection of plant and wildlife, hazardous substances management, waste handling, worker health and safety and community engagement.

Our current exploration activities, which include drilling, geophysical surveys, mapping, sampling and related fieldwork, require permits and approvals that govern the scope and method of operations. These permits impose conditions intended to limit environmental impacts, manage water and waste and require reclamation of disturbed areas. If our projects advance toward development, more extensive environmental review processes may apply, including environmental assessments or environmental impact statements under the NEPA.

Internal controls

We maintain internal controls over our exploration activities and mineral resource and mineral reserve estimation processes designed to ensure that geological, sampling, analytical and technical data used in our mineral resource and mineral reserve estimates are collected, verified and reviewed in accordance with applicable industry standards and Subpart 1300 of Regulation S-K.

These controls include the Company’s oversight of the qualified persons who prepared the technical report summary, including the design and supervision of exploration programs, the implementation and review of appropriate quality control and quality assurance (QC/QA) procedures, and the review of sampling, assay and analytical results for consistency and reliability prior to their use in mineral resource estimation. As part of these controls, the Company relies on the procedures performed and documented by the qualified person, including those described in Section 9.2.3 (Assays) of the technical report summary filed as Exhibit 96.1, which addresses the auditing, verification and assessment of historical and current exploration data.

We also evaluate historical exploration data relied upon in our mineral resource estimates to assess its reliability and relevance, and we review the assumptions, methodologies and conclusions underlying the mineral resource and mineral reserve estimates prepared by the qualified persons. Mineral resource estimates are inherently uncertain and depend on interpretations of geological data, sampling results and assumptions regarding continuity and grade. Our internal controls are designed to manage these risks through review and oversight processes; however, there can be no assurance that such controls will eliminate all uncertainty associated with mineral resource and mineral reserve estimation.

Exploration plans

Our planned exploration and development activities for Pilot Mountain include continued geological mapping, drilling, metallurgical testing, environmental baseline studies and engineering work to support future technical studies and permitting activities. Following completion of the PFS, the qualified persons have recommended that the Project advance to a definitive feasibility study and front-end engineering design, and the PFS design is intended to support the filing of a mine plan of operations with the BLM.

Total cost or book value

Pilot Mountain is carried on our balance sheet at a book value of $30,881,000 as of June 30, 2026 and $16,765,000 as of June 30, 2025.

Annual maintenance costs

Annual costs to maintain our mineral rights for Pilot Mountain consist primarily of claim maintenance fees, option payments and related holding costs, which we estimate to be approximately $84,000 per year.

Property description, location and ownership

Pilot Mountain is located in west-central Nevada on the eastern flank of the Pilot Mountains in Mineral County and covers a historic tungsten district that has been intermittently explored since the early 1900s. The Project area is centered at approximately 38°23’9”N, 117°52’26”W and lies approximately 19 air-kilometers east of the town of Mina, Nevada and approximately 39 kilometers by well-graded gravel road. Hawthorne, the nearest larger community, is located approximately 68 air-kilometers west-northwest of the property. The Project benefits from year-round access via U.S. Highway 95 and local gravel roads.

The Project is situated on approximately 2,259.46 hectares (approximately 22.7 km²) of unpatented lode mining claims, together with four unpatented mill site claims covering approximately 8.09 hectares located at the former Dunham Mill area, on public land administered by the BLM within Sections 7 through 9 and 15 through 18 of Township 6 North, Range 37 East, Mount Diablo Base and Meridian.

​

Table of Contents

The Project comprises four principal mineralized areas: Garnet, Good Hope, Gunmetal and Desert Scheelite, located within three kilometers of one another, together forming Pilot Mountain. In addition, four unpatented Dunham Mill site claims are situated separately from the main claim block, as shown in the map below.

The Project consists of a total of 287 unpatented claims, including mining claims and mill site claims. Of these:

All claims were located and recorded under the U.S. General Mining Law of 1872 and applicable federal and state regulations. All required annual federal claim maintenance fees and county recording fees have been paid with respect to these claims through September 1, 2027. Mineral rights associated with these unpatented mining claims confer the right to explore for, develop and mine locatable minerals on federally administered land, subject to the paramount title of the United States and compliance with applicable BLM surface management requirements and state and federal environmental regulations.

We control the Project through the BFM claims, the mill site claims, the NT claims, the Recently Located BFM Claims and the Recently Located H2O Claims, each held by either Pilot Metals Inc. or Golden Metal Resources, LLC, our wholly owned subsidiaries.

The 45 NT claims, which include the area of the current mineral resources and mineral reserves, are subject to a third-party royalty (the “Platoro Royalty”) of 2% of the gross revenues from the production and sale of minerals from those claims. There are no royalties associated with the BFM claims or the mill site claims, and there are no back-in rights. The royalty is controlled by Apex Royalties.

Permit conditions

Pilot Mountain is located on federally administered public land managed by the BLM. Under BLM regulations, low-impact activities such as geologic mapping, soil sampling and rock sampling may be conducted as casual use without specific permits. Any road or trail construction, mechanized equipment use, drilling or trenching requires filings with the BLM or county, as applicable. Exploration activities that disturb up to approximately five acres can be permitted under a notice-level filing, which may include restrictions to protect biological, historical or archaeological resources. For activities conducted on BLM land, a reclamation bond is required to cover the cost of required reclamation work. The public lands comprising the Project are administered by the BLM through the Stillwater Field Office located in Carson City, Nevada.

Disturbances exceeding five acres require a PoO approved by the BLM, together with compliance with the NEPA (through an EA or an Environmental Impact Statement) and a reclamation permit issued by the NDEP Bureau of Mining Regulation and Reclamation. This process is standard in Nevada.

We currently hold an approved Exploration Plan of Operations (the “Plan”) that incorporated two Notices of Intent for exploration activities on Pilot Mountain: the Desert Scheelite area (NVNV-106362997) and Garnet area (NVNV-106714287). This Plan provides the required permit coverage for our ongoing and planned exploration activities, and we have posted reclamation bonds with the BLM to cover disturbances associated with this work. Our exploration Plan and the associated EA was approved by the BLM on February 12, 2026.

Baseline studies supporting the exploration permitting, comprising biological resources and cultural resources studies, have been completed and support the approved exploration PoO and EA. The baseline studies needed to support mine operation permitting are being developed using data from the ongoing exploration program, with key environmental resources, including geochemistry, surface water and groundwater hydrology, geology and soils, being characterized against the geologic models. The environmental baseline reports, which will include preliminary impact analyses and environmental protection measures for each resource area, will inform the mine plan of operations to be submitted to the BLM for analysis under the NEPA. The Company submitted a mine PoO for the Pilot Mountain project to the BLM which is expected to initiate the NEPA environmental review process with respect to mine development.

Baseline environmental studies completed to date have not identified any federally listed species in the Project area. Three golden eagle nests, inactive for at least the last two years, have been identified within the Project area and, following consultation with the U.S. Fish and Wildlife Service, an application has been submitted for a general take permit in respect of potential impacts during the nesting season. The TRS anticipates that the general take permit will be issued during 2026.

Geochemical characterization of waste rock, ore-grade and tailings materials is being conducted to evaluate acid rock drainage and metals leaching potential in support of mine design, materials management and closure planning. Static testing of 187 waste rock samples classified 97% of materials as non-potentially acid generating, reflecting low sulfide content and strong neutralization capacity associated with the carbonate-rich host lithologies, and ore-grade materials were also classified overwhelmingly as non-potentially acid generating. Thin bands of sulfide-enriched ore-grade material at Desert Scheelite (currently estimated at approximately 3% of ore-grade material) and the sulfide concentrate tailings were classified as potentially acid generating and are proposed to be subject to special handling. Kinetic humidity cell testing and tailings characterization are ongoing. Based on current hydrogeologic information, a pit lake may form in the Desert Scheelite open pit during the post-closure period; a pit lake is not currently expected at Garnet.

A Class III cultural resource inventory has been completed for the entire Project area and approved by the BLM and the Nevada State Historic Preservation Office, and the U.S. Army Corps of Engineers has issued a non-jurisdictional determination in respect of surface water features within or adjacent to the Project area under the Clean Water Act. Three monitoring wells and one piezometer have been installed to support groundwater characterization and baseline water quality monitoring. If the Project advances to construction and operations, additional permits and authorizations will be required, including a mine plan of operations and record of decision from the BLM, a water pollution control permit and mining reclamation permit from the NDEP, a Class II air quality operating permit, a dam safety permit and various other federal, state and local permits and approvals.

Other than the Platoro Royalty and the permitting requirements described in this section, there are no significant encumbrances to the Project, and no violations of, or fines in respect of, applicable permits or environmental requirements have been imposed on us in connection with the Project.

Table of Contents

Permit timelines are difficult to predict as a result of the complex nature of the permits and the control of third-party regulatory agencies on the responses to applications. The financial model calculates a value of the project from the grant of the permits and there may be a considerable delay from the current date.

Accessibility, climate, local resources, infrastructure and physiography

Pilot Mountain is accessible from U.S. Highway 95 by well-graded gravel roads that lead from the highway to the property and to the town of Mina, located approximately 39 kilometers to the west. The town of Hawthorne is located approximately 89 kilometers west of the Project by road.

The Project lies within an arid region of western Nevada characterized by low precipitation and generally dry conditions. Elevations within the Project area range from approximately 1,830 to 2,290 meters above sea level. Vegetation consists of sagebrush and rabbitbrush at lower elevations and pinyon pine and juniper at higher elevations. The Project is situated along the lower eastern slope of the Pilot Mountains, with steeper terrain to the west providing greater geological exposure and alluvial fans covering the eastern and northeastern portions of the property.

Local groundwater sources are sufficient to support current exploration activities, and water for drilling and engineering test work is being sourced from an existing historical borehole on-site. To meet the process water requirements of the planned plant, a 28-kilometer water pipeline and pumping system will be constructed, with fresh water supplied from wells. An existing 120 kV NV Energy power line located south of the Project’s property boundary is expected to provide the point of interconnection for a new 16-kilometer, 120 kV single-circuit overhead transmission line that will supply power to a new 120 kV/13.8 kV substation at the Project site. The existing access road network is adequate for current exploration activities but will require improvements to support potential construction or full operations. Fuel, supplies and mining support services are available in the nearby towns of Mina, Hawthorne, Yerington and Tonopah.

There is currently no operating mine, processing plant or other significant plant and equipment located at Pilot Mountain, and there is no underground development in use. Existing facilities and infrastructure at, or used in connection with, the Project comprise the drill and site access roads established across the Project, historical workings (including the historical test pit and historical disturbance at Desert Scheelite associated with the bulk sampling and limited mining activity described under “—History”), existing water supply wells and the groundwater monitoring wells and piezometer installed by us, together with an offsite core storage and processing facility in Hawthorne, Nevada. The facilities described in this section and under “—Infrastructure” below would be constructed if the Project is developed.

History

Pilot Mountain has been the subject of exploration for more than a century, resulting in an extensive body of geological, geophysical and drilling information, although only limited production has ever been recorded. Exploration began in the early 1900s following the discovery of scheelite on the east flank of the Pilot Mountains in 1916, during a regional increase in tungsten prospecting driven by high prices and new milling capacity in California. Multiple properties were developed at that time, but none recorded production.

In 1921, the United States Geological Survey inspected the district and documented the association of scheelite mineralization with the Gunmetal stock. Their work identified several mineralization styles on the property, including tactite, quartz-calcite-scheelite veins and concentrations of quartz, calcite, silver-bearing galena and scheelite. They considered the tactite style to have the greatest tonnage potential and reported scheelite grades up to 1% WO₃ in underground exposures at the Gunmetal Adit. Subsequent underground development in the 1940s did not materially advance the project and additional work encountered barren marble where tactite had been projected.

Limited production took place during the 1940s and 1950s. Internal reports by Union Carbide Corporation (“UCC”) recorded approximately 130 short tons produced through 1943 at the Garnet mine and approximately 15,378 short tons mined from Gunmetal between 1952 and 1956 after the property was reopened.

58

Table of Contents

Modern exploration began in 1968, when Hecla Mining drilled 16 percussion holes totaling approximately 1,652 meters to test porphyry copper-molybdenum targets between the Good Hope and Desert Scheelite zones and to evaluate tactite at Desert Scheelite. Duval Corporation leased the Desert Scheelite and Gunmetal areas in 1969, completing ground magnetic and induced polarization surveys, and began drilling in 1970. Duval’s early drilling targeted porphyry-style mineralization but returned only weakly mineralized quartz veins. Continued drilling in 1971 intersected copper-tungsten mineralization in sulfide-rich tactite northeast of Desert Scheelite and additional core and percussion drilling followed in 1972 and 1973.

In 1975, W.R. Grace drilled five angled drill holes totaling approximately 728 meters, confirming the width of the steeply dipping mineralization at Desert Scheelite. W.R. Grace did not exercise its option on the property. Duval continued exploration until 1977, when UCC optioned the property. UCC conducted sampling programs at the Gunmetal underground workings, reporting average grades of 0.40-0.50% WO₃ and advanced the project by completing geophysical surveys and additional drilling. Following successful drilling results in extensions of the Desert Scheelite and Middle Gunmetal/South Contact areas, UCC purchased Duval’s interest in December 1978. UCC carried out feasibility studies and a bulk sampling program of approximately 70,000 tonnes at Desert Scheelite before suspending work due to low tungsten prices.

More recent exploration was undertaken between 2011 and 2021. Black Fire Minerals Ltd. acquired an option in 2011 and drilled 15 holes designed to verify historical assay data, supporting the estimation of the first modern mineral resource in 2012. Thor Mining PLC acquired an interest in 2014, reviewed archival UCC data and, in 2017, completed nine drill holes targeting copper-silver mineralization at the Desert Scheelite and Garnet deposits.

Geological setting, mineralization and deposit

Regional geology

Pilot Mountain lies within the Walker Lane structural belt of western Nevada, a northwest-trending zone characterized by strike-slip faulting, extensional basins and associated magmatism that accommodate a significant portion of displacement between the Pacific and North American tectonic plates. Deformation within the belt is expressed through complex fault networks, localized subsidence and magmatic intrusions.

The oldest rocks in the Pilot Mountains are Permian to Jurassic in age and were deposited in back-arc basins related to remnant oceanic arcs and the initiation of the Sierra Nevada arc in the Triassic. Subsequent closure of the back-arc basin in the Jurassic resulted in compressional deformation, known as the Luning-Fencemaker thrust.

Early to Middle Jurassic orogenic movements resulted in deposition of quartzose sandstones and other clastic rocks unconformably over older sediments, with volcanic material becoming increasingly abundant upward. Numerous igneous intrusions emplaced between the Jurassic and Tertiary periods cut the layered rocks in the region, including Cretaceous granodiorite-quartz monzonite stocks and a Tertiary rhyodacite dome exposed in the Pilot Mountains. Widespread felsic to intermediate volcanic rocks of Middle to Upper Tertiary age also occur regionally. Later deformation is reflected in the northwest-trending, right-lateral faulting characteristic of the Walker Lane belt.

Property geology

The Project is underlain by a thick succession of Permian to Jurassic sedimentary and volcanic rocks intruded by Cretaceous granitic stocks, dykes and sills and locally overlain by Tertiary volcanic units. These units have been complexly deformed by thrust faulting and the combined stratigraphy exceeds 6,000 meters in thickness.

The oldest exposed unit is the Permian Mina Formation, comprising marine turbidites, chert and volcanogenic tuffaceous strata. It is prominently exposed in high cliffs south of the Desert Scheelite resource area. Overlying the Mina is the Triassic Luning Formation, the principal host to mineralization on the property. Although no complete section is preserved locally, the Luning is at least 2,300 meters thick in its type area and is subdivided into lower, middle and upper members.

59

Table of Contents

The Lower Jurassic Dunlap Formation stratigraphically overlies the Luning Formation but occurs only in fault contact inside the property boundary, where it instead unconformably overlies the Mina Formation, and is locally exposed along the southwestern edge of the property. It is approximately 1,500 meters thick in the central Pilot Mountains and comprises sandstone, siltstone, shale, conglomerate and minor bioclastic limestone and tuff.

A Cretaceous biotite quartz monzonite stock intruded these units, producing contact metamorphism that converted carbonate rocks to marble and pelitic clastics to hornfels. Calc-silicate and skarn alteration formed locally within calcareous rocks during the later stages of intrusion, with metamorphic effects extending up to 300 meters from the northern contact and mineralization confined largely within ca. 90 meters of the contact. The southern contact is concealed beneath alluvium and sheetwash deposits.

Deposit type

The Desert Scheelite, Garnet, Good Hope, Tremor and Gunmetal zones are tungsten skarns formed where quartz monzonite intrusions interacted with carbonate-bearing sedimentary rocks of the Triassic Luning Formation. Tungsten skarns within the Great Basin formed where granitoid plutons intruded carbonate-rich rocks along the North American Cordilleran magmatic arc. Host rocks include Paleozoic shelf carbonates and Triassic-Jurassic basin carbonates with interlayered volcaniclastic units. Skarn ages range from Jurassic to Cenozoic, with most forming during the Cretaceous.

Associated plutons are typically coarse-grained granitoids crystallized at depths greater than 3 kilometers. Fractionation enriched incompatible elements, including tungsten, in late-stage melts, with tungsten partitioning into magmatic fluids that metasomatized surrounding carbonate rocks. Zoned calc-silicate assemblages formed through prograde and retrograde alteration, with economic tungsten mineralization typically hosted in exoskarns where scheelite is the dominant ore mineral.

Mineralization

Skarn mineralization at Pilot Mountain occurs in two principal compositional types: pyroxene-rich skarn and garnet-rich skarn. The garnet-rich type includes both base-metal-poor and base-metal-enriched subtypes. Skarn composition is controlled by the original carbonate host rocks, while base-metal enrichment is influenced by geochemical variations among the intruding quartz monzonite stocks.

Desert Scheelite

Desert Scheelite is a base-metal-enriched tungsten skarn developed within lower Luning Formation carbonates and interbedded biotite hornfels. The skarn extends approximately 650 meters along the contact of the Desert Scheelite quartz monzonite stock and persists at least 300 meters down-dip. It dips steeply north and contains two mineralized zones on the footwall and hanging-wall sides. Garnets are dominantly grossular-andradite solid solutions with Fe-rich andradite rims. Mineralization consists of abundant scheelite with pyrite, chalcopyrite and sphalerite, locally exceeding 20% in unoxidized samples. Mineralization is oriented sub-vertically and includes three higher-grade tungsten zones within skarn or marble hosts, which may reflect favorable structural and lithological controls. Ankerite, siderite, pyroxene and quartz are also present, with iron carbonates and quartz locally replacing garnet.

Garnet deposit

Both garnet skarns and pyroxene skarns occur at the Garnet deposit. Garnet skarns are interbedded with marble and early-stage pyroxene skarn. Mineralization occurs as high-grade scheelite in pyroxene-quartz-garnet skarn and as disseminated scheelite in rims of zoned garnets set in calcareous matrix. At depth, pyroxene skarns include (1) a dark-green subtype with brown garnet veinlets developed from dolomitic limestone host rocks, typically low-grade or barren in scheelite with possible molybdenite; and (2) a scheelite-rich subtype characterized by quartz and fibrous amphibole replacing coarse tremolite and diopside, occurring as beds up to 60 cm thick and enclosing barren dark-brown garnet porphyroblasts.

Gunmetal zone

Gunmetal contains low-sulfide garnet skarn exhibiting both vertical replacement and stratiform replacement of upper Luning carbonates. Garnets fall within the grossular-andradite solid solution, with Fe-rich rims. Pyroxene and quartz are principal accessory minerals. Scheelite grades vary between beds and with distance from the intrusive contact, with higher grades nearer marble and lower grades near quartz monzonite. Thin, higher-grade skarn horizons occur locally within thicker barren hornfels.

Good Hope zone

Good Hope consists of skarn-altered Luning Formation exposed in a window beneath younger basalt outcrops, between multiple northwest-trending dextral Walker Lane faults. Skarn outcrops strike east-west, dip moderately to the north and are juxtaposed against quartz monzonite to the south. Mineralization contains more sulfides than at Garnet and Gunmetal, including common copper oxides where the skarn is weathered at surface.

Exploration

Since acquiring Pilot Mountain in 2021, we have advanced exploration through data review, updated geological modeling and targeted field programs designed to validate historical information and evaluate extensions of known mineralization. The work completed to date includes rock-chip sampling, geological mapping, geophysical surveying and core and reverse circulation drilling. These activities have also supported preliminary metallurgical and geotechnical considerations for future technical studies. Initial hydrological or geotechnical investigations have commenced and are ongoing on the Pilot Mountain deposits.

Rock chip sampling and geological mapping

In 2024, 21 rock-chip samples were collected and mapping activities were conducted across the Project, with samples analyzed for whole-rock and multi-element geochemistry. Samples of quartz monzonite were analyzed for geochemical fingerprinting to help identify causative intrusions and to assess whether multiple stocks are present. Results were similar across the quartz monzonite samples, suggesting that they belong to the same pluton but represent different levels within the broader porphyry/skarn system.

In 2025, a larger mapping and sampling campaign was conducted, focused on the area south of Desert Scheelite that had previously seen only limited work. Mapping defined large zones of quartz-sericite-pyrite (“QSP”) alteration associated with quartz monzonite dikes intruding the Mina Formation, together with an increase in quartz veining, and 189 rock-chip samples were analyzed for multi-element geochemistry. Samples of quartz-molybdenite-pyrite veins and molybdenite fracture coatings were also collected for Re-Os dating of molybdenite, returning Late Cretaceous ages of approximately 88.5 Ma and 86 Ma and constraining the quartz monzonite intrusion adjacent to Desert Scheelite to Cretaceous in age. In addition, a suite of 17 drill core samples was selected for thin sectioning and petrographic analysis, confirming a skarn assemblage dominated by garnet and pyroxene with varying degrees of retrograde alteration, with scheelite commonly associated with sulfide minerals including pyrite, chalcopyrite and sphalerite.

In December 2025, detailed mapping of the Garnet area was conducted to support the geologic model of the deposit for resource estimation, and in early 2026 limited mapping was conducted in the west Desert Scheelite and Good Hope areas to improve understanding of the structural architecture of the Project area and controls on mineralization and to generate exploration targets. In early 2026, a Quaternary fault study was also commissioned to determine the extent to which mapped Quaternary faults cross the Project area, in order to assist with the siting of facilities. The study determined that the original USGS-mapped locations of certain faults were mis-located due to a data projection issue, and no evidence of Quaternary fault rupture was identified for the Bettles-Well fault.

Geophysical surveys

In June 2023, while operating under the name Golden Metal Resources PLC, we completed a high-resolution induced polarization survey across Pilot Mountain. The program covered the Desert Scheelite deposit and the adjacent quartz monzonite intrusion and delineated three significant chargeability anomalies interpreted as potential disseminated sulfide mineralization. These anomalies provided early evidence of potential porphyry-style systems and guided subsequent exploration priorities. Ground magnetic surveying completed in 2024 assisted in mapping concealed intrusive bodies and alteration patterns.

In 2025, we completed a three-dimensional induced polarization survey that extended coverage southward from the 2023 survey area. Integration of the two surveys confirmed the presence of chargeability anomalies associated with porphyry-style alteration and mineralization. The geophysical work remains early-stage relative to drilling and metallurgical studies, but the results may assist in refining exploration targets and evaluating potential resource expansion opportunities.

Drilling

Between 2024 and 2026, we drilled a total of 189 holes across the Project for a cumulative total of 22,459 meters, comprising 157 diamond core holes and 32 reverse circulation (“RC”) holes. Drilling comprised 81 holes at the Desert Scheelite deposit, 78 holes at the Garnet deposit, 29 holes on various exploration and condemnation targets and one hole targeting Porphyry South. Drill-hole collar locations were surveyed by contracted professional land surveyors and downhole deviation surveys were completed using gyroscopic tools. The drilling totals are summarized in the table below.

Guardian Drilling in 2024-2026

​

Drilling was performed by Diamondback Drilling using Boart Longyear LF Super 90 rigs. Crews applied barium-based grease with organic compounds during coring. Short drilling runs of one to two feet were used in shallow intervals to manage broken ground and mechanical methods, such as mallet tapping, use of a metal stake and barrel shaking, were used to remove core from the barrel where needed. Core boxes were labeled with hole identification, box number and depth intervals, and wood blocks were placed at the end of each run documenting footage, run length and recovered length. Core was washed with water and a plastic brush prior to boxing. Core recovery improved at depth as drilling encountered more competent rock. All RC drilling was performed by Alloy Drilling using an RC1500 rig with a face-sampling hammer to minimize potential downhole contamination, with samples collected at five-foot intervals and field duplicate samples taken every 100 feet.

The 2024-2026 drilling programs increased geological confidence in the Desert Scheelite and Garnet deposits and identified new exploration opportunities, most significantly the newly identified Tremor zone east of Desert Scheelite, where drilling intersected mineralization along a concealed quartz monzonite contact beneath post-mineral volcanic and alluvial cover. The discovery demonstrates the potential for blind mineralized systems elsewhere on the Project and represents a high-priority target for future exploration, together with the Gunmetal and Good Hope zones.

During the fiscal year ended June 30, 2026, we completed 91 core drill holes totaling approximately 11,457 meters and 49 RC drill holes totaling approximately 7,927 meters, collected 4,214 core samples and 1,944 RC samples, and obtained a total of approximately 6,158 assays in respect of those samples, in addition to zero rock-chip samples collected and assayed during the period. These sample totals do not include the blanks, certified reference materials (“CRMs”) or duplicates.

Sample preparation, analysis and security

Sampling data for the Desert Scheelite deposit are derived from drilling completed in the 1970s and by Black Fire (2011-2012), Thor (2017) and us (2024-2026). For the 2024-2026 core drilling, core was transported daily by our staff from the drill site to the core facility in Hawthorne, Nevada, where it was washed, reassembled, meter-marked, logged and photographed wet, dry and under UV light. Sample intervals were based on geological boundaries and ranged from 0.1 to 1.5 meters. Pre-numbered sample tags were stapled into the core boxes, core was cut lengthwise with half-core sampled and the remaining half returned to the boxes. Quarter-core duplicates were collected from the sampled half when required. Samples were bagged with inside and outside bar-coded tags, placed into supersacks, stored in a locked Quonset hut and delivered by our personnel to ALS with full chain-of-custody documentation. Density measurements were collected approximately every 10 meters using wax-coated immersion methods.

ALS prepared and analyzed samples using four-acid digestion (ME-ICP61) with over-limit analyses (OG46, OG62) and pressed-pellet XRF for tungsten values exceeding 450 ppm W (ME-XRF15c). ALS is ISO/IEC 17025 and ISO 9001 accredited. American Assay Laboratories, also ISO/IEC 17025:2017 accredited, completed check analyses for some historical programs. A portion of the Garnet samples was analyzed by MSALABS, an independent commercial geochemical laboratory accredited to ISO/IEC 17025 and ISO 9001, using four-acid digestion with ICP-AES (ICP-230) and, for tungsten values exceeding 450 ppm W, fused-disk XRF (WRX4W). Analytical methods for the 1970s drilling included atomic absorption and colorimetric tungsten determinations, although supporting documentation is limited.

Our 2024-2026 QA/QC program included certified reference materials, blanks and field, coarse and pulp duplicates. RESPEC reviewed CRM and duplicate performance using statistical evaluation, scatterplots, regression analysis and relative percent difference analyses. CRM results showed a modest but persistent negative bias for tungsten (-3% to -15%), good agreement for copper and zinc and higher variability for silver. Blank sample performance was generally acceptable, with isolated failures attributable to localized contamination events rather than persistent contamination. Duplicate samples showed good reproducibility for tungsten, copper and zinc, with silver showing a modest negative bias.

Mineral processing and metallurgical testing

Metallurgical test work programs have been carried out at different laboratories between 2012 and 2026, and this work has identified froth flotation as the preferred processing technology for the beneficiation of the contained tungsten mineralization. The metallurgical test work and recovery methods are summarized in the technical report summary by Samuel, the qualified person responsible for mineral processing and metallurgical testing.

Several metallurgical test work programs have been completed on samples of mineralization from the Project. The work dates to 2012, when Black Fire contracted Amdel Laboratories Perth (“Amdel”) to perform initial mineralogical characterization and metallurgical test work, overseen by Coffey Mining. Test work was also performed in 2013 at the Guangzhou Research Institute of Non-Ferrous Metals (“GZRINM”) to expand on the mineralogy and metallurgical test work, and the last major test program before the current program was performed in 2019 at the Guangdong Institute of Resources Comprehensive Utilization (“GIRCU”).

The 2012 Amdel test work identified scheelite as the target tungsten-bearing mineral, occurring as inclusions or composites with garnet, quartz, calcite and various silicate gangue, with WO₃ grades across samples from different deposits ranging from 0.3% to 0.4% and accessory sulfides including pyrite, chalcopyrite and sphalerite. Gravity separation using two-stage tabling achieved an upgrade ratio of approximately 27:1 with 72.5% tungsten stage recovery to 1.7% of the feed mass, and rougher flotation test work achieved tungsten recoveries of up to 90.7%, although concentrate grades were limited by calcium gangue carryover. Overall tungsten recoveries were 63% to 65% with WO₃ concentrate grades of approximately 65%.

The 2013 GZRINM test work developed two exploratory flotation flowsheets, one also utilizing high-intensity magnetic separation, capable of producing tungsten concentrate at grades and recoveries above 60%, and confirmed scheelite as the dominant tungsten mineral, with liberation of greater than 93% at the tested grind sizes.

The 2019 GIRCU test work carried out mineralogical characterization and evaluated heavy medium separation, gravity separation, magnetic separation and flotation, again selecting flotation as the preferred flowsheet. The final 2019 flowsheet achieved a tungsten recovery of 76% with a WO₃ concentrate grade of approximately 68%.

Base Met Labs was contracted in 2025-2026 to perform the latest test work campaign, focused on optimizing the flotation flowsheet on samples selected to represent the current mineral resource. Base Met Labs received approximately 1,080 kg of sample from 14 geological drill holes and three metallurgical drill holes from the Desert Scheelite deposit, and the program analyzed two composite and nine variability samples, with six additional spatially representative samples used for comminution testing. The main oxide composite achieved a tungsten recovery of 78.5% with a concentrate grade of 62% WO₃ in a locked-cycle flotation test. At the conclusion of the metallurgical program, an estimated recovery of 78.5% for a concentrate grade greater than 50% WO₃ was recommended for use in the Project’s financial model. Test work is ongoing on certain variability samples and on samples from the Garnet deposit.

Mineral resource estimates

The Desert Scheelite and Garnet mineral resource estimates were prepared by RESPEC in accordance with the SEC Modernized Property Disclosure Requirements for Mining Registrants under Subpart 1300 of Regulation S-K. The effective date of the estimates is May 26, 2026. RESPEC is independent of the Company and its subsidiaries. The material assumptions and criteria underlying the mineral resource estimates are summarized below and are set out in Section 11 of the technical report summary filed as Exhibit 96.1 to this Annual Report on Form 20-F.

Mineral resources are reported at a cut-off grade of 0.04% WO₃, which reflects assumptions for open-pit mining, conventional milling and flotation, metallurgical recoveries and operating costs typical for Nevada. The pit-shell optimization applied a mining cost of $3.50/t, processing cost of $23.00/t, general and administrative cost of $5.17/t processed, a WO₃ price of $115,000/t, a silver price of $38.00/oz, a zinc price of $2,700/t, a 75% WO₃ recovery and an 84% WO₃ payability, as well as recoveries of 60% for each of silver, copper and zinc. Silver and zinc are reported within the mineral resources as by-product metals using the WO₃ cut-off grade; no independent cut-off grades were applied to these metals and copper is not separately reported within the mineral resources.

Mineral resources have been classified as indicated and inferred in accordance with S-K 1300 definitions. Indicated resources are primarily informed by our modern angled drilling. Areas underlain by more widely spaced drilling or informed largely by historical drill holes have been classified as inferred. Approximately 84% of the Desert Scheelite mineral resources (inclusive of mineral reserves) by total tonnage (approximately 86% by contained WO₃) have been classified as indicated. Mineral resources are not mineral reserves and do not have demonstrated economic viability.

At the Garnet deposit, our geologic model defines flat-lying skarn horizons and interpreted fault offsets that constrain the distribution of scheelite mineralization. RESPEC interpreted a tungsten mineral domain and a separate silver-zinc domain, and estimated tungsten trioxide, silver, copper and zinc using ordinary kriging, inverse distance and nearest neighbor methods, with the kriged results reported below. The Garnet mineral resources were evaluated assuming potential open-pit extraction and processing by standard flotation and milling techniques and are reported at a 0.04% WO₃ cut-off grade. Silver and zinc are included within the reported resources using the WO₃ cut-off grade and are treated as by-products contingent upon economic extraction of WO₃.
