NexMetals Mining Corp.

This Annual Report on Form 10-K (this “Report”) for NexMetals Mining Corp. (the “Company” or “NEXM”) contains“forward-looking information” and “forward-looking statements” within the meaning of applicable Canadian and U.S. securities laws. Forward-looking information and forward-looking statements in this Report include, but are not limited to, those relating to: the estimated timing and anticipated costs for the Company’s exploration and development activities at the Selebi Mines and Selkirk Mine for the period to June 30, 2026, including surface and underground drilling programmes, capital expenditures, metallurgical and economic study work, and operating costs; the Company’s plans to expand the Mineral Resource at the Selebi Mines through resource expansion drilling and underground development, and to complete updated Mineral Resource Estimates and a Preliminary Economic Assessment in 2026; the Company’s intended metallurgical flowsheet and processing pathway, including the expectation that an on-site smelter or hydrometallurgical facility may not be required and that the Company intends to construct a new concentrator facility at the Selebi Mines; the Company’s plans to advance an updated MRE and metallurgical test work at the Selkirk Mine; the expectation that negative operating cash flows will continue and that additional financing will be required to continue development of the Company’s material projects; the expectation that the proceeds from the November 2025 Financing will be sufficient to fund planned activities and administrative costs into the fourth quarter of 2026; and the Company’s belief that it is well positioned in 2026 to accelerate resource growth and advance both projects toward future economic assessments. In some cases, you can identify forward-looking information by terminology such as “may,” “will,” “should,” “expects,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “potential,” “continue” or the negative of these terms or other comparable terminology. In addition, any statements that refer to expectations, intentions, projections or other characterizations of future events or circumstances contain forward-looking information. Statements containing forward-looking information are not historical facts but instead represent management’s expectations, estimates and projections regarding future events or circumstances.

Forward-looking statements and forward-looking information are not guarantees of future performance and are based upon a number of estimates and assumptions of management at the date the statements are made. Such factors and assumptions may include, but are not limited to: the existing Selebi Mines MRE and the Selkirk MRE, and the assumptions regarding tonnages, grades, recoveries, and metal prices underlying those estimates, remain valid and reliable for purposes of the Company’s exploration planning; that approximately 30,000 metres of drilling at Selebi Main will generate sufficient geological data to support an updated MRE; the Company will be able to generate clean, high-grade separate copper and nickel-cobalt concentrates from blended Selebi Main and Selebi North material that meet industry-standard smelter acceptance criteria; the proceeds from the November 2025 Financing will be sufficient to fund planned activities and administrative costs into the fourth quarter of 2026; the Company will be able to raise additional financing on acceptable terms to continue development beyond the current funding horizon; the Company’s interpretation of what constitutes a “compliant economic study” under the Botswana Mines and Minerals Act will be accepted by regulators; Section 42 and Section 43 applications will be submitted by 31 December 2026; the Selkirk APA study phase (as extended to 17 August 2026) will be complied with, and the Company’s mining licences will remain in good standing; there will be no material changes to the Company’s current operational plans, workforce, contractor arrangements, or input costs (including fuel, power, and labour costs in Botswana); metal prices, exchange rates, and economic conditions will remain consistent with those prevailing at the date of this Report or, in the case of long-term price assumptions used in CuEq calculations, as disclosed herein.

Forward-looking statements and forward-looking information involve known and unknown risks, uncertainties and other factors that may cause our actual results, levels of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by the forward-looking statements. These risks and other factors include, without limitation, the following risk factors, which should be read in conjunction with the more detailed discussion under*“Risk Factors”*in Part I, Item 1A of this Report: drilling results may not confirm the anticipated continuity, grade, or thickness of mineralization; Mineral Resource Estimates may require material downward revision; operational risks (including equipment failures, contractor underperformance, weather, and supply chain disruptions) could delay programmes and increase costs; the Company may be unable to establish Mineral Reserves; the PEA may not demonstrate economic viability given the preliminary nature of the estimates and the significant expenses required to develop the Mines; metallurgical recoveries achieved in laboratory testing may not be reproducible at commercial scale; concentrates may not meet smelter acceptance criteria at larger production volumes; further economic evaluation may demonstrate that a hydrometallurgical facility or smelter is in fact required, materially increasing capital requirements; construction of a new processing facility may be subject to permitting delays, cost overruns, or infrastructure limitations; additional financing may not be available or may not be available on favourable terms; unfavourable economic conditions or investor sentiment may impair the Company’s ability to obtain financing; changes to the operational plan may require expenditures in excess of current working capital, shortening the anticipated funding horizon; the Company’s interpretation of a “compliant economic study” under the Botswana Mines and Minerals Act may not be accepted by regulators; the Company may be unable to obtain or retain necessary permits and licences; the Selkirk APA study phase extension may not be further extended if required; changes to taxation or environmental laws could increase costs or preclude economic development; the Company is exposed to political, economic, and currency risks inherent in operating in Botswana; metal prices and exchange rates may differ materially from those assumed, which could render the Company’s projects uneconomical and cause actual costs and economics to differ materially from those projected; and the other risk factors stated in the Company’s other public filings available on SEDAR+ at www.sedarplus.ca and on EDGAR at www.sec.gov. Readers are cautioned that this list of risk factors should not be construed as exhaustive.

Given these uncertainties, you should not place undue reliance on these forward-looking statements and forward-looking information. Also, forward-looking statements and forward-looking information represent our management’s beliefs and assumptions only as of the date hereof. You should read this Report and the documents that we have filed as exhibits to this Report completely and with the understanding that our actual future results may be materially different from what we expect.

Except as required by law, we assume no obligation to update these forward-looking statements and forward looking information publicly, or to update the reasons actual results could differ materially from those anticipated in these forward-looking statements, even if new information becomes available in the future. Given these risks and uncertainties, readers are cautioned not to place undue reliance on such forward-looking statements.

CAUTIONARY NOTE TO U.S. RESIDENTS CONCERNING DISCLOSURE OF MINERAL RESOURCES

On October 31, 2018, the U.S. Securities and Exchange Commission (the “SEC”) adopted the Modernization of Property Disclosures for Mining Registrants (the “New Rule”), introducing significant changes to the existing mining disclosure framework to better align it with international industry and regulatory practice, including NI 43-101. The New Rule was codified as 17 CFR Subpart 220.1300 and 229.601(b)(96) (collectively, “S-K 1300”) and replaced SEC Industry Guide 7. The New Rule became effective as of February 25, 2019, and issuers are required to comply with the New Rule as of the annual report for their first fiscal year beginning on or after January 1, 2021, and earlier in certain circumstances.

All mineral estimates constituting mining operations that are material to our business or financial condition included in this Report, and in the documents incorporated by reference herein, have been prepared in accordance with S-K 1300 and are supported by initial assessments prepared in accordance with the requirements of S-K 1300. S-K 1300 provides for the disclosure of: (i) “Inferred Mineral Resources”, which investors should understand have the lowest level of geological confidence of all mineral resources and thus may not be considered when assessing the economic viability of a mining project and may not be converted to a Mineral Reserve; (ii) “Indicated Mineral Resources,” which investors should understand have a lower level of confidence than that of a “Measured Mineral Resource” and thus may be converted only to a “Probable Mineral Reserve”; and (iii) “Measured Mineral Resources,” which investors should understand have sufficient geological certainty to be converted to a “Proven Mineral Reserve” or to a “Probable Mineral Reserve”. Investors are cautioned not to assume that all or any part of Measured Mineral Resources or Indicated Mineral Resources will ever be converted into Mineral Reserves as defined by S-K 1300. Investors are cautioned not to assume that all or any part of an Inferred Mineral Resource exists or is economically or legally mineable, or that an Inferred Mineral Resource will ever be upgraded to a higher category.

CAUTIONARY NOTE REGARDING EXPLORATION STAGE COMPANIES

We are an exploration stage issuer and do not currently have any known mineral reserves and cannot expect to have known mineral reserves unless and until an appropriate technical and economic study is completed for the Mines (as defined below) that shows “Proven Mineral Reserves” or “Probable Mineral Reserves” as defined by Regulation S-K 1300. We currently do not have any “Proven Mineral Reserves” or “Probable Mineral Reserves”. There can be no assurance that the Mines or any of our other properties contains or will contain any such SEC-compliant “Proven Mineral Reserves” or “Probable Mineral Reserves” or that, even if such reserves are found, the quantities of any such reserves warrant continued operations or that we will be successful in economically recovering them.
