Attention All Contrarian Investors, Big Profits Are Possible – Time to Alter Your Portfolio Mix

TORONTO, Sept. 05, 2018 - McEwen Mining Inc. (NYSE: MUX) (TSX: MUX) would like to remind you of our quickly approaching Investor Day which is being held this Thursday, September 6^th from 12 pm to 2 pm EDT. We are inviting all precious metals analysts, market letter writers, shareholders and contrarian investors to attend this event in person or participate in the global live webcast. We have made a lot of progress this year and we want to share all the details with you.

We are inviting you to come and learn how:

• Exciting new drill intercepts at Black Fox have encountered high grades of up to 20 ounces per ton of gold;
• We have been building our gold resources at Black Fox and Gold Bar;
• Our newest mine, Gold Bar is progressing quickly to production;
• We plan to extend the mine life in Mexico by 12 years without onerous financing needs;
• Los Azules, a large copper project and our biggest possible value creator, is being transformed from a remote, limited access exploration project to having year-round access and moving quickly towards permitting.

Our Chairman and Chief Owner, Rob McEwen, has just increased the cost base of his investment in the Company by $25 million to $160 million. Come find out why.

It will likely be a big surprise to most investors to learn that many gold stocks have delivered far superior returns to the broad market indices. Since the start of 2016 to present, while the Dow Jones Industrials and S&P 500 have increased by 52% and 45%, respectively, the share price of McEwen Mining has increased by 76% and yet it is trading at 21% of its 2011 high of $9.15.

If you haven’t considered an investment in precious metals for quite a while, you should now. Why? Because there hasn’t been a better time in many years. The downside risk is much lower than the broad market and the potential for large capital gains is considerable. Consider these two facts: commodity prices are cyclical; and today the value of commodities relative to equities is at the lowest point in 48 years.

Join us this Thursday Sept. 6^th to learn why precious metals are the next place to invest and why you should consider having McEwen Mining in your portfolio. The event will be held at Vantage Venues, (previously St. Andrew’s Conference Centre) at 150 King St. West, Toronto, 27th floor, Caledonia Room, from 12:00 pm to 2:00 in the afternoon.

To reserve a seat, please RSVP to cd@mcewenmining.com or info@mcewenmining.com, or call our office at telephone 647-258-0395 or toll free 866-441-0690.
