DISCLAIMER FORWARD-LOOKING STATEMENTS AND INFORMATION This presentation contains "forward-looking statements" within the meaning of applicable United States securities legislation (collectively referred to as "forward-looking information" ("FLI")), and readers should read the cautionary notes related to FLI included later in this presentation. 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 Silver & Gold Inc. (the “Company” 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, Contango 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. Contango 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"). Contango 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 Contango 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 Contango reports are or will be economically or legally mineable. For more detail regarding the FS, please see Contango'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.

For additional details on the Johnson Tract Project, see NI 43-101 Technical Report titled “Updated Mineral Resource Estimate and NI 43-101 Technical Report for the Johnson Tract Project, Alaska”, dated August 25, 2022 (effective date of July 12, 2022) authored by Ray C. Brown, James N. Gray, P.Geo. and Lyn Jones, P.Eng, see: https://cdn.prod.website-files.com/5fc5d36fd44fd675102e4420/66b39f847ac30bd736ac91ad_hg-technical-report-25aug-2022_compressed.pdf.

For more detail regarding the Johnson Tract IA, please see Contango's press release dated May 6, 2025: https://www.contangoore.com/press-release/contango-announces-s-k-1300-technical-report-summary-with-robust-economics-and-one-year-payback-for-its-johnson-tract-project The information contained in, or otherwise accessible through, the links are not part of and are not incorporated by reference into this investor presentation. The technical information in this presentation related to the Kitsault Valley Project (owned by Dolly Varden Silver Corporation (“Dolly Varden”), a wholly-owned subsidiary of Contango) has been reviewed and approved by Robert van Egmond, P.Geo. VP Exploration - Canada, who is considered, by virtue of his education, experience and professional association, a qualified person under NI 43-101. Mr. van Egmond is not considered independent for purposes of NI 43-101 as he is an employee of Dolly Varden. This presentation also contains references to estimates of mineral resources (as such term is defined in NI 43-101). The estimation of mineral resources is inherently uncertain and involves subjective judgments about many relevant factors. Mineral resources that are not mineral reserves do not have demonstrated economic viability. The accuracy of any such estimates is a function of the quantity and quality of available data, and of the assumptions made and judgments used in engineering and geological interpretation (including estimated future production from Dolly Varden’s projects, if any, the anticipated amounts and grades that will be mined and the estimated level of recovery that will be realized), which may prove to be unreliable and depend, to a certain extent, upon the analysis of drilling results and statistical inferences that ultimately may prove to be inaccurate. Some of the mineral resources at the Kitsault Valley Project are categorized as indicated and some as inferred mineral resources. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Mineral resource estimates do not account for mineability, selectivity, mining loss and dilution. These mineral resource estimates include inferred mineral resources that are normally considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. There is also no certainty that these inferred mineral resources will be converted to measured and indicated categories through further drilling, or into mineral reserves, once economic considerations are applied. Certain information in this presentation is based upon, and certain information is extracted directly from, an NI 43-101 compliant technical report prepared by Dolly Varden for the Kitsault Valley Project (the “Technical Report”), a copy of which is available under its SEDAR+ profile at www.sedarplus.ca. The Technical Report includes relevant information regarding the effective date and the assumptions, parameters and methods of the mineral resource estimates cited in this presentation, as well as information regarding data verification, exploration procedures and other matters relevant to the scientific and technical disclosure contained in this presentation in respect of the Kitsault Valley Project. You are encouraged to read the Technical Report in full and any information summarized or extracted therefrom in this presentation should not be read or relied upon out of context. All such technical information in this presentation is subject to the assumptions and qualifications contained in the Technical Report. The Technical Report was not prepared in accordance with S-K 1300. A qualified person has not done sufficient work to classify the mineral resource estimates derived from the Technical Report and included in this presentation as current estimates of S-K 1300 mineral resources. The securities of Contango have not been approved or disapproved by the United States Securities and Exchange Commission, or any other securities commission or regulatory authority in the United States or any other jurisdiction, nor have any of the foregoing authorities passed upon or endorsed the merits this presentation or confirmed the accuracy or adequacy of the information contained in this presentation. Any representation to the contrary is a criminal offense. This presentation does not constitute an offer to sell or the solicitation of an offer to buy the securities of Contango. This presentation does not contain all of the information that would normally appear in a prospectus under applicable United States securities laws. Prospective investors should carefully read Contango's disclosure documents filed on Edgar, especially the risk factors contained in such filings, before making an investment decision with respect to investing in the securities of Contango.

Drill & Muck at Mine Site Load & Weigh at Mine Site Transport via Rail/Road/Barge Ore mined underground Loaded into covered/sealed containers at the mine site Small environmental footprint Containers loaded and weighed at mine site Ore containers loaded onto trucks Covered/sealed containers prevent “fugitive dust” DSO approach eliminates the need for onsite processing and tailings storage. This drastically reduces the onsite environmental footprint, reduces permitting risk and lowers upfront capital cost.

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. 21

Assumed metal prices are US$1650/oz for gold (Au), US$20/oz for silver (Ag), US$3.50/lb. copper (Cu), US$1/lb. lead (Pb), and US$1.50/lb. for zinc (Zn) 3. Gold Equivalent (“AuEq”) is based on assumed metal prices and payable metal recoveries of 97% for Au, 85% for Ag, 85% Cu, 72% Pb and 92% Zn from metallurgical test work completed in 2022. 4. AuEq equals = Au g/t + Ag g/t × 0.01 + Cu% × 1.27 + Pb% × 0.31 + Zn% × 0.59 5. An average bulk density value of 2.84 used as determined by conventional analytical methods for assay samples 6. Capping applied to assays to restrict the impact of high-grade outliers 7. Preliminary underground constrains were applied, including the elimination of isolated or scattered blocks above cut-off grade to define the “reasonable prospects of eventual economic extraction” for the Mineral Resource Estimate 8. Mineral resources as reported are undiluted 9. Mineral resource tonnages have been rounded to reflect the precision of the estimate 10. Readers are cautioned that mineral resources that are not mineral reserves do not have demonstrated economic viability Notes: Kitsalt Valley Resources (Homestake and Dolly Varden) 1 -Mineral resources are not mineral reserves, as they do not have demonstrated economic viability although, as per Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) requirements, the mineral resources reported above have been determined to have demonstrated reasonable prospects for eventual economic extraction. 2 -The mineral resources were estimated in accordance with the CIM Standards on Mineral Resources and Reserves, Definitions (2014) and Best Practices Guidelines (2019) prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council. 3 - The resources reported above are derived from the Technical Report on The Combined Kitsault Valley Project, British Columbia, Canada dated effective September 28, 2022 (“Kitsault Valley Project Technical Report”) 4 -The cut-off grade for the Homestake claim block mineral resources is 2.0 g/t AuEq, which was determined using average block grade values within the estimation domains and a Au price of $1,300 per troy ounce (“per tr oz”), a Ag price of US$20.00/tr oz and a Cu price of US$2.50/pound, and mill recoveries of 92% for Au, 88% from Ag and 87.5% for Cu and combined mining, milling, and general and administrative costs of approximately US$109/ton. 5 - The cut-off grade for the Dolly Varden claim block mineral resource is 150 g/t Ag, which was determined using a Ag price of US$20.00/tr oz, a recovery of 90% and combined mining, milling, and general and administrative costs of US$80/ton and was supported by comparison to similar projects. 6 - Differences may occur in totals due to rounding
