49 End Notes Note 1: 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 as required by the Canadian Securities Administrations, 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. Note 2: The feasibility of mining at our El Gallo Complex (El Gallo 1 and El Gallo 2) has not been established in accordance with SEC Guide 7 (or NI 43-101). 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. 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 completing the commissioning of an expansion of El Gallo Phase 1. There are significant risks and uncertainty associated expanding production without a feasibility or pre-feasibility study. The El Gallo 1 production expansion has not been explored, developed or analyzed in sufficient detail to complete an independent feasibility or pre-feasibility study. Note 3: 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.

53 Mineral resources, which are not mineral reserves, do not have demonstrated economic viability. The foregoing reports are available under the Corporation's profile on SEDAR (www.sedar.com). Inferred resources are too speculative geologically to have economic considerations applied to them. The cumulative resource and reserve figures set forth above are comprised of the following: Note 4: For the current resources and reserves for San José see the March 13, 2014 press release entitled “McEwen Mining Announces Updated Reserve & Resource Estimate at the San Jose Mine in Argentina.” For the current technical report on the San José Mine see: "Technical Report on San José Silver-Gold Mine, Santa Cruz, Argentina" dated August 15, 2013 with an effective date of December 31 2012, prepared by Eugene Puritch, P.Eng., David Burga, P.Geo., Alfred Hayden, P.Eng., James L. Pearson, P.Eng., and Fred H. Brown, P.Geo., all of whom are qualified persons and all of whom are independent of McEwen Mining, each as defined by NI 43-101 Note 5: There is no current feasibility study on the El Gallo 2 project. The Corporation is currently evaluating historical figures in contemplation of being able to produce an updated economic model. The figures presented for El Gallo 2 are historical in nature and therefore cannot be relied upon and are presented for information purposes only. These figures are disclosed in the: "El Gallo Complex Phase II project, NI 43-101 Technical Report Feasibility Study, Mocorito Municipality, Sinaloa, Mexico" with an effective date of September 10, 2012, prepared by M3 Engineering along with a team of associates (the "Phase II Report"). The authors of the Phase 2 Report, Stan Timler - M3 Engineering, Mike Hester - Independent Mining Consultants (Reserves), Dawn Garcia - SRK Consulting (Environmental), Richard Kehmeier and Brian Hartman - Pincock Allen & Holt (El Gallo Deposit Resource), John Read - McEwen Mining consultant (Palmarito Insitu, Historic Waste Dumps and Historic tailings Resource), are each qualified persons and all of whom but John Read are independent of McEwen Mining, such as defined by NI 43-101. Note 6: The Corporation is conducting studies which are expected, but cannot be guaranteed, to reduce the historical projected cost of the El Gallo 2 project. Ongoing work on the El Gallo 2 project are based on internal estimates by the corporation which although are considered reasonable by the corporation do not constitute a preliminary economic assessment, feasibility or pre-feasibility study. There are significant risks and uncertainty associated expanding or commencing production without a feasibility or pre-feasibility study. The proposed El Gallo 2 mine has not been explored, developed or analyzed in sufficient detail to complete a current 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 2 project.

56 Cautionary Note Regarding NON-GAAP Measures In this presentation, we have provided information prepared or calculated according to U.S. GAAP, as well as provided some non-U.S. GAAP ("non-GAAP") performance measures. Because the non-GAAP performance measures do not have any standardized meaning prescribed by U.S. GAAP, they may not be comparable to similar measures presented by other companies. (1) Total Cash Costs and All-in Sustaining Costs (AISC) Total cash costs consist of mining, processing, on-site general and administrative costs, community and permitting costs related to current explorations, royalty costs, refining and treatment charges (for both doré and concentrate products), sales costs, export taxes and operational stripping costs. All-in sustaining cash costs consist of total cash costs (as described above), plus environmental rehabilitation costs, mine site exploration and development costs, and sustaining capital expenditures. In order to arrive at our consolidated all-in sustaining costs, we also include corporate general and administrative expenses. Depreciation is excluded from both total cash costs and all-in sustaining cash costs. Total cash cost and all-in sustaining cash cost per ounce are calculated on a co-product basis by dividing the respective proportionate share of the total cash costs and all-in sustaining cash costs for the period attributable to each metal by the ounces of each respective metal sold. We use and report these measures to provide additional information regarding operational efficiencies both on a consolidated and an individual mine basis, and believe these measures provide investors and analysts with useful information about our underlying costs of operations. A reconciliation to the nearest U.S. GAAP measure is provided in McEwen Mining's Quarterly Report on Form 10-Q for the quarter ended September 30, 2014. (2) Adjusted net income (loss) Adjusted net income (loss) excludes the following items from net income (loss): impairment charges, net of tax; foreign currency gains and losses, including the impact of the devaluation Argentine peso relative to the U.S. dollar; other non-recurring items, if applicable. We use and report this measure because we believe it provides investors and analysts with a useful measure of the underlying operating performance of our core mining business. A reconciliation to the nearest U.S. GAAP measure is provided in McEwen Mining's Quarterly Report on Form 10-Q for the quarter ended September 30, 2014. (3) Earnings from mining operations Earnings from mining operations consists of gold and silver revenues from our El Gallo 1 mine and our 49% attributable share from the San José mine, and deducts Production Costs Applicable to Sales. It also includes depreciation and amortization expense incurred at the mining operations, but does not include amortization expense related to the fair value increments on historical business acquisitions (fair value paid in excess of the carrying value of the underlying assets and liabilities assumed on the date of acquisition). We use and report this measure because we believe it provides investors and analysts with a useful measure of the underlying earnings from our mining operations. A reconciliation to the nearest U.S. GAAP measure is provided in McEwen Mining's Quarterly Report on Form 10-Q for the quarter ended September 30, 2014.
