Cautionary Statement 29 This presentation contains certain forward-looking statements and information, including "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. The forward-looking statements and information expressed, as at the date of this presentation, McEwen Mining Inc.'s (the "Company") estimates, forecasts, projections, expectations or beliefs as to future events and results. Forward-looking statements and information are necessarily based upon a number of estimates and assumptions that, while considered reasonable by management, are inherently subject to significant business, economic and competitive uncertainties, risks and contingencies, and there can be no assurance that such statements and information will prove to be accurate. Therefore, actual results and future events could differ materially from those anticipated in such statements and information. Risks and uncertainties that could cause results or future events to differ materially from current expectations expressed or implied by the forward-looking statements and information include, but are not limited to, factors associated with fluctuations in the market price of precious metals, mining industry risks, political, economic, social and security risks associated with foreign operations, the ability of the corporation to receive or receive in a timely manner permits or other approvals required in connection with operations, risks associated with the construction of mining operations and commencement of production and the projected costs thereof, risks related to litigation, the state of the capital markets, environmental risks and hazards, uncertainty as to calculation of mineral resources and reserves, risk of delisting from a public exchange, and other risks. The Company's dividend policy will be reviewed periodically by the Board of Directors and is subject to change based on certain factors such as the capital needs of the Company and its future operating results. Readers should not place undue reliance on forward-looking statements or information included herein, which speak only as of the date hereof. The Company undertakes no obligation to reissue or update forward-looking statements or information as a result of new information or events after the date hereof except as may be required by law. See McEwen Mining's Annual Report on Form 10-K for the fiscal year ended December 31, 2018 and Quarterly Report on Form 10-Q for the quarter ended March 31, 2019 and other filings with the Securities and Exchange Commission, under the caption "Risk Factors", for additional information on risks, uncertainties and other factors relating to the forward-looking statements and information regarding the Company. All forward-looking statements and information made in this presentation are qualified by this cautionary statement. Unless otherwise stated, all currency information quoted in this presentation is in U.S. dollars. The technical contents of this presentation have been reviewed and approved by Chris Stewart, P.Eng., President & COO, the exploration technical contents of this presentation have been reviewed and approved by Sylvain Guerard, P. Geo., SVP Exploration and the reserves and resources contents of the presentation have been reviewed and approved by Luke Willis, P. Geo., Director of Resource Modelling, each of whom is a Qualified Person as defined by Canadian Securities Administrators National Instrument 43-101 "Standards of Disclosure for Mineral Projects". Risk adverse? Forget about buying our shares. Past performance is unreliable in predicting the future. Unexpected events can happen and can change forecasts.

Cautionary Statement (cont’d) 30 McEwen Mining Inc. is required to prepare reports under the Securities Exchange Act of 1934 and the Canadian Securities Administrators’ National Instrument 43-101 “Standards of Disclosure for Mineral Projects” (“NI 43-101”), under the Canadian securities laws because we are listed on the Toronto Stock Exchange (“TSX”) and subject to Canadian securities laws. Standards under NI 43-101 are materially different than the standards generally permitted in reports filed with the United States (“U.S.”) Securities and Exchange Commission (“SEC”). Definitions of terms under NI 43-101 differ materially from the definitions of those and related terms in Industry Guide 7 (“Industry Guide 7”) promulgated by the SEC. Under U.S. standards, mineralization may not be classified as a “Reserve” unless a determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. Under Industry Guide 7 standards, a “Final” or “Bankable” feasibility study or other report is required to report reserves, the three-year historical average precious metals prices are used in any reserve or cash flow analysis to designate reserves and the primary environmental analysis or report must be filed with the appropriate government authority. One consequence of these differences is that “reserves” calculated in accordance with Canadian standards may not be “Reserves” under Industry Guide 7 standards. U.S. investors should be aware that the McEwen Mining properties with reserves as defined by Industry Guide 7 are the Black Fox mine, the Gold Bar project and the San Jose mine. All other properties do not have “Reserves” as defined by Industry Guide 7 and Investors are cautioned not to assume that any part or all the disclosed mineralized material will be confirmed or converted into Industry Guide 7 compliant “Reserves”.

Canadian Mining Journal: Time for a Mining Rant. By Rob McEwen 37 It’s time for a mining rant! Our most important audience, our shareowners, need to be given more respect. We, the management of the mining industry, have allowed the securities regulators, stock exchanges, lawyers, accountants and governments to confuse, abuse and excessively tax us and in turn our shareowners. We produce financial statements, information circulars and other impenetrable documents that I am certain very few shareowners read due to the massive size and mind numbing narrative of these documents. Think back to a time when you can remember a prospectus that had a one-page summary, or a one-page discussion of risk factors. Let me tell you, it was a very long time ago! Our shareowners have a right to understand every document that we give them. It should be clear, concise, in plain language and that can be quickly comprehended. For that matter, management also needs to understand the materials we are sending our shareowners, which frequently doesn’t appear to be the case. For example, do you understand fully the 16-page letter of representations and warranties that your auditor drafts and demands that you sign before giving you an unqualified audit opinion on your annual financials? Do you think your shareowners have a chance in hell of following all the notes to your financials that might run 25-50 pages long? Why have we let our financials reports become so obtuse? We need to take back the ground we have lost to these pencil pushers and insist on getting value for the great and growing expense that accounting has become. Internal auditors, external auditors, tax auditors and consulting auditors have become a common feature and a plague. Have you ever looked at the size of the Securities Acts that dictate the behaviour of public company management? These documents have grown tremendously in size and scope. They have been drafted by a myriad of lawyers with the stated objective of protecting the public, but the unstated objective appears to be business development for the legal community. The beadyeyed lawyers who work for a few years at the security regulators, long enough to author a new regulation that they become an expert in and then return to their law firm in order to advise clients, public companies, on their brilliant bit of confusion. There are so many security rules and regulations that no one in the world has the mental capacity or capability to know and understand all these rules. As a result, our regulators have inadvertently created an environment that is the opposite of what they say they are doing. The multitude of rules has produced a playground for the criminally inspired and inclined, because there is no common knowledge of all the rules. As a result, the thieves are free to steal with virtual impunity and the crimes keep growing in size. Think of Madoff, Enron, Northern Telecom, BreX and the many other thefts of shareowners’ wealth. How many more rules, regulations and defrauding of the public has to occur before we scream stop this nonsense? We should be pushing for much, much fewer securities regulations so that everyone has a chance to know all the rules and would be able can spot and stop a criminal instantly! Let’s use Moses as a good example and give everyone the 10 commandments of securities law. Many of us have used the unfortunate phrase “a mining friendly jurisdiction” to describe the location of our property, but experience has demonstrated that this statement is at best a short-lived fantasy! We need to aggressively demand stronger protections for our shareowners’ capital from theavarice and capricious nature of governments! Get battle ready! It’s time to go on the offensive! Let’s show our shareowners’ that we are serious about protecting their capital!
