TORONTO, ONTARIO–(Marketwired – April 7, 2015) – McEwen Mining Inc. (NYSE:MUX)(TSX:MUX) is extremely disappointed to report an armed robbery occurred today at our El Gallo 1 mine in Sinaloa, Mexico. An estimated 900 kilograms of gold-bearing concentrate containing approximately 7,000 ounces of gold were stolen from the refinery. The crime is being vigorously investigated by the Mexican authorities.

The Company maintains insurance against these types of incidents and is working closely with its insurance carrier to determine the extent of available coverage. However, the Company's policy will not be sufficient to cover the entire expected loss.

No employees were seriously injured and there was no material damage to any of the Company's facilities. Mining and processing activities have not been impacted and continue uninterrupted.
