Item 2.02 Results of Operations and Financial Condition.

On August 13, 2025, Contango ORE, Inc. (the “Company”) issued a press release announcing its financial results for the quarter ended June 30, 2025. A copy of the press release is attached as Exhibit 99.1 hereto and is incorporated herein by reference.

The information included herein and in Exhibit 99.1 shall not be deemed “filed” for purposes of Section 18 of the Exchange Act, or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act.

Item 7.01 Regulation FD Disclosure.

On August 13, 2025, the Company made available a new corporate presentation. A copy of this presentation is furnished as Exhibit 99.2 to this Current Report on Form 8-K and is available on the Company’s website at www.contangoore.com.

The Company’s presentation furnished as Exhibit 99.2 to this Current Report contains non-GAAP financial measures. Generally, a non-GAAP financial measure is a numerical measure of a company’s performance, financial position, or cash flows that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with United States generally accepted accounting principles, or GAAP. Reconciliations of these non-GAAP financial measures are not included in the furnished presentation due to the inherent difficulty and impracticality of quantifying certain amounts that would be required to calculate the most directly comparable GAAP financial measures. In addition, certain of the non-GAAP financial measures have been prepared by Kinross Gold Corporation, the Company’s partner in, and the manager of, Peak Gold, LLC, a joint venture company in which the Company currently holds a 30% interest, and are based on International Financial Reporting Standards (IFRS) accounting standards and detailed information to which the Company has not had access to at this time. As a result, the Company is unable to quantify certain amounts that would be required to be included in the most directly comparable GAAP financial measure without unreasonable efforts.

The information included herein and in Exhibit 99.2 shall not be deemed “filed” for purposes of Section 18 of the Exchange Act, or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act.

Cautionary Note Regarding Forward-Looking Statements

Many of the statements included or incorporated in this Current Report on Form 8-K and the furnished exhibit constitute “forward-looking statements.” In particular, they include statements relating to future actions, strategies, future operating and financial performance, ability to realize the anticipated benefits of various transactions and the Company’s future financial results. These forward-looking statements are based on current expectations and projections about future events. Readers are cautioned that forward-looking statements are not guarantees of future operating and financial performance or results and involve substantial risks and uncertainties that cannot be predicted or quantified, and, consequently, the actual performance of the Company may differ materially from that expressed or implied by such forward-looking statements. Such risks and uncertainties include, but are not limited to, factors described from time to time in the Company’s Annual Report on Form 10-K and Quarterly Reports on Form 10-Q filed with the Securities and Exchange Commission (including the sections entitled “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” contained therein).

NEWS RELEASE

CONTANGO ORE, INC.

Contango Announces Record High $23.0 Million in Income from Operations and $15.9 Million in Net Income for the Quarter Ended June 30, 2025

FAIRBANKS, AK -- (August 13, 2025) -- Contango ORE, Inc. (“Contango” or the “Company”) (NYSE American: CTGO) announced today that it filed with the Securities and Exchange Commission its Form 10-Q for the quarter ended June 30, 2025 (“Q2-2025”) compared with the quarter ended June 30, 2024 (“Q2-2024”).

Rick Van Nieuwenhuyse, President and CEO of the Company, stated, “Production during the second quarter of 2025 continued to exceed quarterly guidance with record high net income of $15.9 million. During the quarter 17,764 ounces of gold was sold with cash costs of $1,416 per ounce of gold sold and all-in-sustaining costs (“AISC”) of $1,548 of gold sold, well below the 2025 target of $1,625 per ounce. The third campaign of 2025 is scheduled to commence on August 14, 2025 with Contango’s share of production expected to be 15,000 ounces of gold. On a 100% basis, the third campaign is expected to process 250,000 tons and an average gold grade of approximately 0.23 ounces per ton (~7 grams per ton).”

Statement of Operations for Q2-2025 compared to Q2-2024:

The Company reported total income for operations of $23.0 million (“M”) in Q2-2025 compared to a loss from operations of $3.1 M for Q2-2024. For Q2-2025, the Company reported net income of $15.9 M or $1.26 per issued share and $1.24 per fully-diluted share. This compares to a net loss of $18.5 M for Q2-2024 or a loss of $1.90 per issued and fully-diluted share. In Q2-2025, Contango sold 17,764 ounces of gold with cash costs on a by-product basis, per ounce (“Cash Costs”) of $1,416 and all-in-sustaining costs per ounce (“AISC”) of $1,548.

Statement of Cash Flows for the Six Months Ended June 30, 2025 compared to June 30, 2024:

Net cash provided from operating activities was $36.9 M for the six months ended June 30, 2025 (“YTD-2025”), a significant improvement compared to net cash used of $6.9 M for the six months ended June 30, 2024 (“YTD-2024”). The increase in net cash provided by operating activities was primarily driven by gold production at the Manh Choh project and the receipt of $54.0 M in cash distributions from the Peak Gold JV. Cash used in investing activities was $159,870 for YTD-2025 compared to $27.2 M in YTD-2024, which related to cash invested in the Peak Gold JV to fund Contango’s share of Manh Choh development costs in 2024. Cash used in financing activities were $20.5 M for YTD-2025, which primarily related to principal repayments of $22.0 M on its credit facility. This compares to cash inflows of $42.7 M in YTD-2024, primarily related to debt

drawdowns of $30.0 M on its credit facility and an equity raise of $14.2 M. The Company’s unrestricted cash position as of June 30, 2025 was $36.5 M compared to $20.1 M as of December 31, 2024.

During Q2-2025 and subsequent to period end, the Company has the following updates:

FORWARD-LOOKING STATEMENTS

This press release contains forward-looking statements regarding Contango that are intended to be covered by the safe harbor for “forward-looking statements” provided by the Private Securities Litigation Reform Act of 1995, based on Contango’s current expectations and includes statements regarding future results of operations, quality and nature of the asset base, the assumptions upon which estimates are based and other expectations, beliefs, plans, objectives, assumptions, strategies or statements about future events or performance (often, but not always, using words such as “expects”, “projects”, “anticipates”, “plans”, “estimates”, “potential”, “possible”, “probable”, or “intends”, or stating that certain actions, events or results “may”, “will”, “should”, or “could” be taken, occur or be achieved).

These risks include, but are not limited to: the risks of the exploration and the mining industry (for example, operational risks in exploring for and developing mineral reserves; risks and uncertainties involving geology; the speculative nature of the mining industry; the uncertainty of estimates and projections relating to future production, costs and expenses; the volatility of natural resources prices, including prices of gold and associated minerals; the existence and extent of commercially exploitable minerals in properties acquired by Contango or the Peak Gold JV; ability to realize the anticipated benefits of the Peak Gold JV; potential delays or changes in plans with respect to exploration or development projects or capital expenditures; the interpretation of exploration results and the estimation of mineral resources; the loss of key employees or consultants; health, safety and environmental risks and risks related to weather and other natural disasters); uncertainties as to the availability and cost of financing; Contango’s inability to retain or maintain its relative ownership interest in the Peak Gold JV; inability to realize expected value from acquisitions; inability of our management team to execute its plans to meet its goals; the extent of disruptions caused by an outbreak of disease, such as the COVID-19 pandemic; and the possibility that government policies may change, political developments may occur or governmental approvals may be delayed or withheld, including as a result of presidential and congressional elections in the U.S. or the inability to obtain mining permits. Additional information on these and other factors which could affect Contango’s exploration program or financial results are included

in Contango’s other reports on file with the U.S. Securities and Exchange Commission. Investors are cautioned that any forward-looking statements are not guarantees of future performance and actual results or developments may differ materially from the projections in the forward-looking statements.

FORWARD LOOKING STATEMENTS The Feasibility Study (“FS”) referenced herein that relates to Peak Gold, LLC (“Peak Gold”), was prepared by Kinross Gold Corporation (“Kinross”), which controls the Manager of Peak Gold and holds 70% of its outstanding membership interests, in accordance with Canadian National Instrument 43-101 (NI 43-101). Contango Ore, Inc. (“CORE” or “Contango”) owns the remaining 30% membership interest in Peak Gold, and must rely on Kinross and its affiliates for the FS and related information. Further, CORE is not subject to regulation by Canadian regulatory authorities and no Canadian regulatory authority has reviewed the FS or passed upon its accuracy or compliance with NI 43-101. The terms “mineral resource”, “measured mineral resource”, “indicated mineral resource” and “inferred mineral resource” as used in the resource estimate, the FS and this presentation are Canadian mining terms as defined in accordance with NI 43-101. In the United States, mining disclosure is reported under sub-part 1300 of Regulation S-K (“S-K 1300”). Under S-K 1300, the U.S. Securities and Exchange Commission (“SEC”) recognizes estimates of “Measured Mineral Resources”, “Indicated Mineral Resources” and “Inferred Mineral Resources”. In addition, the definitions of “Proven Mineral Reserves” and “Probable Mineral Reserves” are substantially similar to international standards. Under S-K 1300, an SEC registrant with material mining operations must disclose specified information in its SEC filings concerning mineral resources, in addition to mineral reserves, which have been determined on one or more of its properties. Such mineral resources and reserves are supported by a technical report summary (the “S-K 1300 Report”), which is dated and signed by a qualified person or persons, and identifies and summarizes the information reviewed and conclusions reached by each qualified person about the SEC registrant’s mineral resources or mineral reserves determined to be on each material property. CORE prepared an S-K 1300 Report, dated May 12, 2023, based on the FS, that presented mineral resource estimates and mineral reserve estimates for the Manh Choh project as of December 31, 2022 (the "Manh Choh S-K 1300 Report"). CORE prepared an additional S-K 1300 Report, dated May 26, 2023, based on historical and recent drill hole assay information, that presented mineral resource estimates for the Lucky Shot project as of May 26, 2023 (the "Lucky Shot S-K 1300 Report"). Investors are cautioned that while the S-K 1300 definitions are “substantially similar” to the NI 43-101 definitions, there are differences between the two. Accordingly, there is no assurance any mineral reserve or mineral resource estimates that Peak Gold may report as “probable mineral reserves”, “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” under NI 43-101 would be the same had CORE prepared the mineral reserve or mineral resource estimates under S-K 1300. Further, U.S. investors are also cautioned that while the SEC recognizes “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” under S-K 1300, investors should not assume that any part or all of the mineralization in these categories will ever be converted into a higher category of mineral resources or into mineral reserves. Mineralization that has been characterized as resources has a greater degree of uncertainty as to its existence and feasibility than mineralization that has been characterized as reserves. Accordingly, investors are cautioned not to assume that any measured mineral resources, indicated mineral resources or inferred mineral resources that CORE reports are or will be economically or legally mineable. For more detail regarding the FS, please see CORE's press release dated May 26, 2023: https://www.contangoore.com/press-release/contango-ore-announces-completion-of-s-k-1300-technical-report-summary-for-its-manh-choh-project-in-alaska.

NON-GAAP RECONCILIATION DISCLAIMER This presentation contains forward looking estimates of all-in sustaining cost (“AISC”), resources, free cash flow and EBITDA, which are financial measures not determined in accordance with United States generally accepted accounting principles (“GAAP”). We cannot provide a reconciliation of estimated AISC, resources and EBITDA to estimated costs of goods sold, assets and net income, which are the GAAP financial measures most directly comparable to such non-GAAP measures, without unreasonable efforts due to the inherent difficulty and impracticality of quantifying certain amounts that would be required to calculate projected AISC, resources and EBITDA. In addition, the estimates of AISC, resources and EBITDA have been prepared by Kinross and are based on IFRS accounting standards and detailed information that the Company does not have access to at this time. These amounts that would require unreasonable effort to quantify could be significant, such that the amount of projected GAAP cost of goods sold, assets and net income would vary substantially from the amount of projected AISC, resources and EBITDA. 27 FORWARD DISCLOSURE SPECIFIC TO HIGHGOLD TRANSACTION This corporate presentation contains forward-looking statements and certain “forward-looking information” (within the meaning of Canadian securities legislation) regarding Contango, production estimates on the Manh Choh Project, expectations with respect to the development of the Johnson Tract Project, Contango’s growth plans and the continued cooperation of Contango with CIRI, that are intended to be covered by the safe harbor for “forward-looking statements” provided by the Private Securities Litigation Reform Act of 1995, based on Contango’s current expectations or assumptions as to the outcome and timing of such future events and includes statements regarding future results of operations, quality and nature of the asset base, the assumptions upon which estimates are based and other expectations, beliefs, plans, objectives, assumptions, strategies or statements about future events or performance (often, but not always, using words such as “expects”, “believes”, “targets”, “approximately”, “projects”, “anticipates”, “plans”, “estimates”, “potential”, “possible”, “probable”, or “intends”, or stating that certain actions, events or results “may”, “will”, “should”, or “could” be taken, occur or be achieved). Forward-looking statements are based on current expectations, estimates and projections that involve a number of risks and uncertainties, which could cause actual results to differ materially from those, reflected in the statements. These risks include, but are not limited to: risks inherent to the exploration and mining industry (for example, operational risks in exploring for and, developing mineral reserves; risks and uncertainties involving geology; the speculative nature of the mining industry; the uncertainty of estimates and projections relating to future production, costs and expenses; the volatility of natural resources prices, including prices of gold and associated minerals; the existence and extent of commercially exploitable minerals in properties acquired by Contango or the Peak Gold JV; ability to realize the anticipated benefits of the Peak Gold JV and the Johnson Tract Project; potential delays or changes in plans with respect to exploration or development projects or capital expenditures; the interpretation of exploration results and the estimation of mineral resources; the loss of key employees or consultants; health, safety and environmental risks and risks related to weather and other natural disasters); uncertainties as to the availability and cost of financing; Contango’s inability to retain or maintain its relative ownership interest in the Peak Gold JV; inability to realize expected value from acquisitions; inability of our management team to execute its plans to meet its goals; the extent of disruptions caused by an outbreak of disease, such as the COVID-19 pandemic; and the possibility that government policies may change, political developments may occur or governmental approvals may be delayed or withheld, including as a result of presidential and congressional elections in the U.S. or the inability to obtain mining permits. Additional information on these and other factors which could affect Contango’s exploration program or financial results are included in Contango’s other reports on file with the U.S. Securities and Exchange Commission. Investors are cautioned that any forward-looking statements are not guarantees of future performance and actual results or developments may differ materially from the projections in the forward-looking statements. Forward-looking statements are based on the estimates and opinions of management at the time the statements are made. Contango does not assume any obligation to update forward-looking statements should circumstances or management’s estimates or opinions change.
