Item 7.01 Regulation FD Disclosure.
On August 7, 2026, NexMetals Mining Corp. (the “Company”) issued a news release announcing that it has filed an independent National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) technical report supporting the 2026 Mineral Resource Estimate for its Selkirk Project in Botswana (the “Technical Report”). A copy of this press release is attached as Exhibit 99.1 hereto and a copy of the Technical Report is attached as Exhibit 99.2 hereto. Exhibits 99.1 and 99.2 are incorporated herein by reference. The Company undertakes no obligation to update, supplement or amend the materials attached hereto as Exhibit 99.1. The Technical Report has been filed in Canada under the Company’s profile on SEDAR+ at sedarplus.ca and is being furnished on this Current Report on Form 8-K. The Company plans to file a related Regulation S-K 1300 compliant technical report on a Current Report on Form 8-K as soon as reasonably practicable.
Cautionary Statements to Investors on Reserves and Resources
The news release and technical report furnished herewith use the terms “mineral resources”, “indicated mineral resources” and “inferred mineral resources” as such terms are defined under NI 43-101. NI 43-101 is a rule developed by the Canadian Securities Administrators, which establishes standards for all public disclosure a Canadian issuer makes of scientific and technical information concerning mineral projects.
On October 31, 2018, the SEC adopted new mining disclosure rules (“S-K 1300”) that are more closely aligned with current industry and global regulatory practices and standards, including NI 43-101, with which we comply because we are also a “reporting issuer” under Canadian securities laws. While S-K 1300 is more closely aligned with NI 43-101 than the prior mining disclosure rules of the Securities and Exchange Commission, there are some differences. Accordingly, there is no assurance any mineral resources that the Company may report as “indicated mineral resources” and “inferred mineral resources” under NI 43-101 will be the same as the reserve or resource estimates prepared under S-K 1300. Investors should not assume that any part or all of indicated mineral resources or inferred mineral resources will ever be converted into a higher category of mineral resources or into mineral reserves. Mineralization described using these terms has a greater amount of uncertainty as to their existence and feasibility than mineralization that has been characterized as reserves. Accordingly, investors are cautioned not to assume that any “indicated mineral resources”, or “inferred mineral resources” on the Company’s projects are or will be economically or legally mineable. Further, “inferred resources” have a greater amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Therefore, investors are also cautioned not to assume that all or any part of the inferred resources exist. In accordance with Canadian rules, estimates of “inferred mineral resources” cannot form the basis of feasibility or other economic studies, except in limited circumstances where permitted under NI 43-101.
The information in this Current Report on Form 8-K (including Exhibits 99.1 and 99.2 attached hereto) is being furnished and shall not be deemed to be filed for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise be subject to the liabilities of that section, nor shall it be deemed to be incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, whether made before or after the date hereof and regardless of any general incorporation language in such filing.

Exhibit 99.1
NexMetals Files NI 43-101 Technical Report for
2026 Selkirk Mineral Resource Estimate
Vancouver, British Columbia, August 7, 2026 – NexMetals Mining Corp. (TSXV: NEXM) (Nasdaq: NEXM) (the “Company” or “NEXM”) is pleased to announce that it has filed an independent National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) technical report supporting the 2026 Mineral Resource Estimate (the “2026 MRE”) for its Selkirk Project in Botswana, originally announced on June 24, 2026. Selkirk is a past-producing copper-nickel-platinum group elements (“PGEs”) project located approximately 75 kilometres northeast of the Company’s flagship Selebi Project.
The 2026 MRE outlines an Indicated Mineral Resource of 78.2 million tonnes grading 0.66% copper equivalent (“CuEq”), containing approximately 1.1 billion pounds of copper equivalent, together with an Inferred Mineral Resource of 15.1 million tonnes grading 0.60% CuEq, containing approximately 200 million pounds of copper equivalent. The 2026 MRE increases the Selkirk Project’s CuEq metal inventory by approximately 70% and reflects a significant conversion of Mineral Resources from the Inferred to Indicated category following a successful re-assaying and twin drilling campaign.
The technical report, entitled “NI 43-101 Technical Report – June 2026 Mineral Resource Estimate Selkirk Nickel-Copper-PGE Project, Botswana”, was prepared by The MSA Group (Pty) Ltd. (“MSA”) with an effective date of June 22, 2026. The technical report has been filed under the Company’s profile on SEDAR+ at www.sedarplus.ca, furnished under the Company’s profile on EDGAR at www.sec.gov and is also available on the Company’s website. The Company plans to file a related Regulation S-K 1300 compliant technical report on a Current Report on Form 8-K on EDGAR as soon as reasonably practicable. There are no material differences between the technical report and the Mineral Resource Estimate previously disclosed.

Notes:
| 1. | All tabulated data have been rounded and as a result minor computational errors may occur. |
| 2. | Mineral Resources, which are not Mineral Reserves, have no demonstrated economic viability. There is no guarantee that that all or any part of the Mineral Resource will be converted into a Mineral Reserve. The estimate of Mineral Resources may be materially affected by geology, environment, permitting, legal title, taxation, socio-political, marketing, or other relevant issues. |

Mineral Resource Data and Quality Control
The historical sampling data was collected by the previous owner and operator, Tati Nickel Mining Company (“TNMC”), which included Ni and Cu assays and selective Pd, Pd and Au assays. The historical data was verified through completion of eleven twin diamond drillholes and approximately 6,000 samples taken for assay from the remaining TNMC core by NEXM. Resampling included intervals previously sampled by TNMC, as well as some extension sampling, and included a full suite of elements including Ni, Cu, Co, Pt, Pd, Au and Ag. Statistical checks completed by MSA revealed no material bias between the historical and recent sample assays.
Data from drillholes completed prior to TNMC, as well as TNMC underground drilling and channel sampling, was not verifiable and was not included in the 2026 MRE. A total of 216 diamond drillholes were used to estimate the 2026 MRE, including the TNMC drillholes, NEXM’s twin drilling and an infill drillhole completed by NEXM.
The TNMC assays were completed at the TNMC Phoenix Laboratory. At the time of preparation and analysis, TNMC owned both the Phoenix Mine and Selkirk, and the laboratory was not independent of the operator. From 2011, the Phoenix Mine Laboratory held accreditation with the South African National Accreditation System (SANAS), and with the International Organization for Standardization/International Electrotechnical Commission (ISO/IEC) 17025 for chemical analyses. Ni and Cu were analysed by XRF and Pt, Pd and Au by 50 g lead collection fire assay. Relative Density measurements were obtained by water immersion method.
The Company’s drill core was logged, photographed and marked for sampling in nominal lengths of one metre. The core samples were cut in half longitudinally using a rotating diamond saw. The bagged core samples were given a unique sample reference number, bagged and despatched to ALS Laboratories Ltd. (“ALS”) in Johannesburg, South Africa for analysis (SANAS Accredited Testing Laboratory, No. T0387). Samples were analysed for Ni, Cu, and Co using a peroxide fusion preparation and inductively coupled plasma atomic emission spectrometry (ICP-AES) finish (ME-ICP81). Analyses for Pt, Pd, and Au were by fire assay (30 g nominal sample weight) with an ICP-AES finish (PGMICP23), also by ALS. A suite of 48 elements, including Ag, was analysed using a 4-acid digest and ICP-AES finish (ME-ICP61). Specific gravity measurements were also completed by ALS.

NEXM’s drilling and resampling was subjected to a comprehensive programme of quality assurance and quality control by the Company, independent of the laboratories’ own QA/QC measures, including certified reference materials (5%), blank samples (5%), coarse duplicate samples (5%) and pulp duplicate samples (5%). The Qualified Person (“QP”), Mr. J.C. Witley (BSc Hons, MSc (Eng.)), is satisfied that the assay results are of sufficient accuracy and precision for use in Mineral Resource estimation.
Mineral Resource Estimate
The 2026 MRE was completed by The MSA Group in Johannesburg, South Africa.
The 2026 MRE was estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Best Practice Guidelines and is reported in accordance with the 2014 CIM Definition Standards, which have been incorporated by reference into NI 43-101.
The Selkirk Mineral Resource is contained within the Selkirk Meta Gabbro, which is a massive roughly sub-vertical body plunging at a moderate dip to the south-southwest approximately 300 to 450 m wide and has been intersected by drilling from surface to over 500 m deep. Sulphide mineralisation consists primarily of disseminated pyrrhotite and chalcopyrite and veins and pods of massive sulphide. The Selkirk Meta Gabbro has been intruded by several phases of later dykes which are barren.
Estimation comprised modelling of the Selkirk metagabbro, dykes and a surface representing the base of oxidation, followed by the construction of an implicit probability mineralised shell within the metagabbro including drillhole sample intervals greater than an NSR value of US$20. A three-dimensional block model with parent cells of 20 mX by 20mY by 10mRL and appropriate sub-celling was used to estimate metal grades and density by ordinary kriging. Volumes representing mined voids and oxidised material were removed and dykes were assigned grades of zero. NSR was then calculated for each block model cell using the estimated grades, metal prices, recoveries, off-site costs and payabilities. The Mineral Resource model was classified into the Indicated and Inferred categories, taking into account data quality, geological modelling uncertainty, drillhole spacing and kriging outputs. The majority of the Indicated Mineral Resource is informed by drillholes closer than 60 m apart up to maximum spacing of 75 m.
The Mineral Resource was reported using a NSR based optimised pit-shell. Using concentrate costs of US$20/tonne, G&A of US$1.35 per tonne and royalites of 3% for base metals and 5% for precious metals, blocks that occur within the pit-shell with estimated NSR above US$25/tonne satisfy cut-off grade criteria and, together with the optimised pit shell, the QP considers that reasonable prospects for eventual economic extraction (RPEEE) for the Mineral Resource have been demonstrated.
Qualified Persons
Mr. J.C. Witley (BSc Hons, MSc (Eng.)) is a geologist with more than 35 years’ experience in base and precious metals exploration and mining as well as Mineral Resource evaluation and reporting. He is Head of Mineral Resources for The MSA Group (an independent consulting company), is registered as Pr.Sci.Nat. with the South African Council for Natural Scientific Professions (SACNASP) and is a Fellow of the Geological Society of South Africa (GSSA). Mr. Witley has the appropriate relevant qualifications and experience to be considered a “Qualified Person” for the style and type of mineralisation and activity being undertaken as defined in NI 43-101 and is considered independent of NEXM pursuant to NI 43-101. Mr. Witley has reviewed and approved the technical and scientific information within this news release pertaining to the 2026 MRE.
Verification included a site visit by the QP to inspect historical mineralized core, observe existing infrastructure, including the Selkirk underground ramp and remains of massive sulphide stockpiles at surface, and inspect several surface drillhole collar locations (both historical and recent). The mineralisation in five of the twin holes was inspected by the QP. In addition, a selection of samples collected by NEXM have been verified against independently accessed assay certificates, and a random selection of historical database results have been compared against digital records.
