77 End Notes The Company has included non-GAAP performance measures, cash costs, and all-in sustaining cost per gold ounce, throughout this document on a historic and estimated forward looking basis. In the mining industry, these are common performance measures but do not have any standardized meaning. The Company believes that, in addition to conventional measures prepared in accordance with GAAP, the Company and certain investors use this information to evaluate the Company’s performance and ability to generate cash flow. Accordingly, it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. The Company uses a conversion ratio of 52:1 when converting silver oz to gold equivalent oz. The non-GAAP performance measures are based on metrics proposed by the World Gold Council. Given these metrics are not final, there may be future changes to the metrics. Such information relating to the San José Mine is provided to us by Minera Santa Cruz S.A. who is responsible for and has supplied to the Company all reported results from the San José Mine. The technical information pertaining to the San José Mine contained herein is, with few exceptions as noted, based entirely on information provided to the Company by Minera Santa Cruz S.A. ("MSC"). The Company's joint venture partner, a subsidiary of Hochschild Mining plc, and its affiliates other than MSC do not accept responsibility for the use of project data or the adequacy or accuracy of this information. As the Company is not the operator of the San José Mine, there can be no assurance that production information reported to the Company by MSC is accurate, the Company has not independently verified such information and readers are therefore cautioned regarding the extent to which they should rely upon such information. The Company has also made estimates of potential future cash flow from MSC based on a sustained silver price of $22/oz and gold price of $1,434/oz as well as assumptions over operating costs, capital expenditures, production levels, taxes, and other factors which are beyond our control since we are not the operator of the San José Mine. Non-GAAP Disclosure

78 End Notes Guidance to US Investors: McEwen Mining prepares its resource estimates in accordance with standards of the Canadian Institute of Mining, Metallurgy and Petroleum referred to in Canadian National Instrument 43-101 (NI 43-101). These standards are different from the standards generally permitted in reports filed with the SEC. Under NI 43-101, McEwen Mining reports measured, indicated and inferred resources, measurements which are generally not permitted in filings made with the SEC. The estimation of measured resources and indicated resources involve greater uncertainty as to their existence and economic feasibility than the estimation of proven and probable reserves. U.S. investors are cautioned not to assume that any part of measured or indicated resources will ever be converted into economically mineable reserves. The estimation of inferred resources involves far greater uncertainty as to their existence and economic viability than the estimation of other categories of resources. El Gallo Project, Mexico: The feasibility of mining at our El Gallo Complex and Gold Bar Project, has not been established in accordance with SEC Guide 7, and we have no proven or probable reserves on those properties as defined by U.S. law. A "reserve," as defined by regulation of the SEC, is that part of a mineral deposit which could be economically and legally extracted or produced at the time of the reserve determination. A reserve requires a feasibility study demonstrating with reasonable certainty that the deposit can be economically extracted and produced. There are no assurances that we will be able to prove that there are reserves at the El Gallo Complex and Gold Bar Project. The forward looking information contained in this presentation such as estimated timelines to production, production levels, capital expenditure requirements, and operating costs have been estimated without the benefit of a feasibility study so there can be no assurance over the accuracy of those estimates or that commercial production will be achieved. As at the date of this presentation, McEwen Mining is evaluating an expansion of El Gallo Phase 1. There are significant risks and uncertainty associated expanding production without a feasibility or pre-feasibility study. The proposed El Gallo 1 production expansion has not been explored, developed or analyzed in sufficient detail to complete an independent feasibility or pre-feasibility study and may ultimately be determined to lack one or more geological, engineering, legal, operating, economic, social, environmental, and other relevant factors reasonably required to serve as the basis for a final decision to complete the development of all or part of the El Gallo 1 expansion. San José Mine, Argentina: Minera Santa Cruz S.A., the owner of the San José mine, is responsible for and has supplied to the Company all reported results from the San José mine. McEwen Mining's joint venture partner, a subsidiary of Hochschild Mining plc, and its affiliates other than MSC do not accept responsibility for the use of project data or the adequacy or accuracy of this release. As the Company is not the operator of the San José mine, there can be no assurance that production information reported to the Company by MSC is accurate, the Company has not independently verified such information and readers are therefore cautioned regarding the extent to which they should rely upon such information.
