Contango Silver & Gold Inc.

Item 7.01 Regulation FD Disclosure. On September 22, 2026, Contango Silver & Gold Inc. (the “Company” or “Contango”) 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 (“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, as amended (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 8.01 Other Events. On September 22, 2026, Contango announced that it had completed its Technical Report Summary, with an effective date of September 11, 2026 (the “TRS”), on the Kitsault Valley Project (the “Project”) in accordance with the mining property disclosure rules specified in subpart 1300 of Regulation S-K. A copy of the TRS is filed as Exhibit 96.1 to this Current Report on Form 8-K and is incorporated herein by reference. A copy of the related press release is filed as Exhibit 99.1 to this Current Report on Form 8-K. The foregoing description of the TRS does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the TRS attached hereto as Exhibit 96.1. Cautionary Note Regarding Mineral Resources Mineral resources are not mineral reserves and do not have demonstrated economic viability. No measured mineral resources or mineral reserves are reported for the Project. The estimate is intended to support continued evaluation of potential underground extraction and does not establish a mine development decision. Indicated mineral resources have a lower level of confidence than measured mineral resources, and inferred mineral resources have a lower level of confidence than indicated mineral resources; inferred mineral resources cannot be assumed to be converted to indicated or measured mineral resources or to mineral reserves, and actual upgrading depends on future drilling, sampling, metallurgical, engineering, environmental, permitting and economic results and is not assured. The mineral resource estimate is subject to material uncertainties including local geological and grade continuity, high-grade sample influence, historical data and mined-out geometry, density variability, metallurgical response and product quality, mining dimensions and ground conditions, access and infrastructure requirements, water and waste management, permitting, and commodity-price and operating-cost assumptions. 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). This Current Report on Form 8-K and the exhibits thereto contain forward-looking information and forward-looking statements within the meaning of applicable U.S. and Canadian securities laws (“
