McEwen Mining to Acquire Black Fox From Primero

TORONTO, Aug. 10, 2017 -- McEwen Mining Inc. (NYSE:MUX) (TSX:MUX) (“McEwen”) is pleased to announce that it has reached an agreement with Primero Mining Corp. to purchase its Black Fox Complex and associated assets and liabilities located in the world-famous gold mining camp of Timmins, Canada. The agreed purchase price is $35 million, subject to closing adjustments. Definitive documentation is expected to be completed before the end of this month.

“Buying the Black Fox Complex provides fantastic synergies with our recently acquired Timmins deposits. Our objective is to build a long-term production platform with a robust pipeline of production, development and exploration assets, all feeding into a single processing facility. This acquisition will add immediately to our gold production, but is just the beginning of a new chapter of growth for McEwen Mining,” said Rob McEwen, Chairman and Chief Owner. “Black Fox comes with a talented operating team, an underground mine producing 50-60,000 ounces of gold in 2017⁽¹⁾, a processing facility with excess capacity, two future development opportunities, and excellent exploration potential. Combined with our existing portfolio of Timmins deposits, I believe this is a logical and potent combination.”
