Exhibit 99.1

Gold & Silver Production<br>Plus Huge Copper Option<br>Corporate Presentation<br>January 2025
Cautionary Statement<br>This presentation and the information included herein do not constitute an offer to buy or the<br>solicitation of an offer to subscribe for or to buy any of the securities described herein, nor<br>shall there be any sale of these securities in any jurisdiction in which such offer, solicitation<br>or sale would be unlawful prior to registration or qualification under the securities laws of any<br>such jurisdiction.<br>This presentation contains certain forward-looking statements and information, including<br>"forward-looking statements" within the meaning of the Private Securities Litigation Reform<br>Act of 1995 ("Forward-looking Statements"). The Forward-looking Statements are intended<br>to be subject to the safe harbor provided by Section 27a of the Securities Act of 1933,<br>Section 21e of the Securities Exchange Act of 1934 and Private Securities Litigation Reform<br>Act of 1995. The Forward-looking Statements express, as at the date of this presentation,<br>McEwen Mining Inc. (the "Company") estimates, forecasts, projections, expectations or<br>beliefs as to future events and results. Forward-looking Statements are necessarily based<br>upon a number of estimates and assumptions that, while considered reasonable by<br>management, are inherently subject to significant business, economic and competitive<br>uncertainties, risks and contingencies. There can be no assurance that such statements and<br>information will prove to be accurate. Therefore, actual results and future events could differ<br>materially from those anticipated in such statements and information. Risks and<br>uncertainties that could cause results or future events to differ materially from current<br>expectations expressed or implied by the Forward-looking Statements include, but are not<br>limited to, factors associated with fluctuations in the market price of precious metals, mining<br>industry risks, political, economic, social and security risks associated with foreign<br>operations, the ability of the corporation to receive or receive in a timely manner permits or<br>other approvals required in connection with operations, risks associated with the<br>construction of mining operations and commencement of production and the projected costs<br>thereof, risks related to litigation, the state of the capital markets, environmental risks and<br>hazards, uncertainty as to calculation of mineral resources and reserves, risk of delisting<br>from a public exchange, and other risks. Readers should not place undue reliance on<br>Forward-looking Statements, which speak only as of the date hereof. The Company<br>undertakes no obligation to reissue or update Forward-looking Statements as a result of new<br>information or events after the date hereof, except as required by law. See McEwen Mining's<br>Annual Report on Form 10-K/A for the fiscal year ended December 31, 2023, the Quarterly<br>Report on Form 10-Q for the quarters ended March 31, 2024, and other filings with the<br>Securities and Exchange Commission (the “SEC”), under the caption "Risk Factors", for<br>additional information on risks, uncertainties and other factors relating to the Forward-looking Statements. All Forward-looking Statements made in this presentation are qualified<br>by this cautionary statement. Unless otherwise stated, all currency information quoted in this<br>presentation is in U.S. dollars.<br>The technical contents of this presentation, including reserves, have been reviewed and<br>approved by William Shaver, COO; the exploration technical contents of this presentation<br>including resources content have been reviewed and approved by Luke Willis, P. Geo.,<br>Director of Resource Modelling; all are Qualified Persons as defined by Canadian Securities<br>Administrators National Instrument 43-101 "Standards of Disclosure for Mineral Projects".<br>Securities and Exchange Commission (“SEC”).We are subject to the reporting requirements<br>of the Securities and Exchange Act of 1934, as amended (the “Exchange Act”) and<br>applicable Canadian securities laws, and as a result, we have reported our mineral reserves<br>and mineral resources according to two different standards. U.S. reporting requirements are<br>governed by Item 1300 of Regulation S-K (“S-K 1300”), as issued by the U.S. Securities and<br>Exchange Commission (“SEC”). Canadian reporting requirements for disclosure of mineral<br>properties are governed by National Instrument 43-101 Standards of Disclosure for Mineral<br>Projects (“NI 43-101”), as adopted from the definitions provided by the Canadian Institute of<br>Mining, Metallurgy and Petroleum. Both sets of reporting standards have similar goals in<br>terms of conveying an appropriate level of confidence in the disclosures being reported, but<br>the standards embody slightly different approaches and definitions. All disclosure of mineral<br>resources and mineral reserves in this report are reported in accordance with S-K 1300.<br>Investors should be aware that the estimation of measured resources and indicated<br>resources involve greater uncertainty as to their existence and economic feasibility than the<br>estimation of proven and probable reserves, and therefore investors are cautioned not to<br>assume that all or any part of measured or indicated resources will ever be converted into<br>S-K 1300 compliant reserves. The estimation of inferred resources involves far greater<br>uncertainty as to their existence and economic viability than the estimation of other<br>categories of resources. It is generally assumed that the majority of Inferred resources will<br>be later upgraded to the Indicated or Measured categories with further exploration. Investors<br>are cautioned not to assume that all or any part of inferred resources exist, or that they can<br>be mined legally or economically.

NON-GAAP Measures<br>In this presentation, we have provided information prepared or calculated according to<br>U.S. GAAP, as well as provided some non-U.S. GAAP ("non-GAAP") performance<br>measures. Because the non-GAAP performance measures do not have any<br>standardized meaning prescribed by U.S. GAAP, they may not be comparable to<br>similar measures presented by other companies.<br>Total Cash Costs per GEO, and All-in Sustaining Costs (“AISC”) per GEO. Total cash costs consist of mining, processing, on-site general and administrative<br>costs, community and permitting costs related to current explorations, royalty costs,<br>refining and treatment charges (for both doré and concentrate products), sales costs,<br>export taxes and operational stripping costs. All-in sustaining cash costs consist of<br>total cash costs (as described above), plus environmental rehabilitation costs,<br>amortization of the asset retirement costs related to operating sites, sustaining<br>exploration and development costs, and sustaining capital expenditures. In order to<br>arrive at our consolidated all-in sustaining costs, we also include corporate general and<br>administrative expenses. Depreciation is excluded from both total cash costs and all-in<br>sustaining cash costs. For both total cash costs and all-in sustaining costs we include<br>our attributable share of total cash costs from operations where we hold less than a<br>100% economic share in the production, such as MSC, where we hold a 49% interest.<br>Total cash cost and all-in sustaining cash cost per GEO sold are calculated on a co- product basis by dividing the respective proportionate share of the total cash costs and<br>all-in sustaining cash costs for the period attributable to each metal by the ounces of<br>each respective metal sold. We use and report these measures to provide additional<br>information regarding operational efficiencies both on a consolidated and an individual<br>mine basis, and believe that these measures provide investors and analysts with<br>useful information about our underlying costs of operations. A reconciliation to the<br>nearest U.S. GAAP measure is provided in McEwen Mining's Annual Report on Form<br>10-K/A for the year ended December 31, 2023.<br>Earnings from Mining Operations<br>The term Earnings from Mining Operations used in this presentation is a non-GAAP<br>financial measure. We use and report this measure because we believe it provides<br>investors and analysts with a useful measure of the underlying earnings from our<br>mining operations. We define Earnings from Mining Operations as Gold and Silver<br>Revenues from our El Gallo Mine, Black Fox Mine, and our 49% attributable share of<br>the San José Mine's Net Sales, less their respective Production Costs Applicable to<br>Sales. To the extent that Production Costs Applicable to Sales may include<br>depreciation and amortization expense related to the fair value increments on historical<br>business acquisitions (fair value paid in excess of the carrying value of the underlying<br>assets and liabilities assumed on the date of acquisition), we deduct this expense in<br>order to arrive at Production Costs Applicable to Sales that only include depreciation<br>and amortization expense incurred at the mine-site level. The San José Mine Net<br>Sales and Production Costs Applicable to Sales are presented, on a 100% basis, in<br>Note 5 of McEwen Mining's Annual Report on Form 10-K/A for the year ended<br>December 31, 2023.<br>Cash, Investments and Precious Metals<br>The term cash, investments and precious metals used in this presentation is a<br>non-GAAP financial measure. We report this measure to better understand our liquidity<br>in each reporting period. Cash, investments and precious metals is calculated as the<br>sum of cash, investments and ounces of doré held in inventory, valued at the London<br>P.M. Fix spot price at the corresponding period. A reconciliation to the most directly<br>comparable U.S. GAAP measure, Sales of Gold and Silver, is provided in McEwen<br>Mining's Annual Report on Form 10-K/A for the year ended December 31, 2023.<br>MUX: Cautionary Note Regarding
