McEwen Mining Gold Bar Accident Update

TORONTO, May 16, 2019 - McEwen Mining Inc. (NYSE: MUX) (TSX: MUX) provides an update on the fatal accident involving a contractor's employee that occurred on Monday, May 13, 2019 at the Gold Bar Mine in Nevada.

The formal investigation by local authorities is not complete, but preliminary analysis by McEwen Mining Inc. suggests that the truck driver, Mr. Dean V. Pilcher, may have suffered a medical emergency while operating the haul truck prior to losing control, running up an embankment and overturning. Mr. Pilcher was found within minutes by another truck driver who immediately called for assistance. The section of haul road immediately around the accident site remains closed to allow for the investigation. Mine operations such as crushing and stacking on the heap leach pad resumed on Tuesday, drawing on available stockpiles of ore, and we expect that mining activities will restart today. The Gold Bar team continues to ramp-up operations to achieve our goal of commercial production during Q2.

We convey our deep sympathy to Mr. Pilcher’s family, friends and colleagues for their sudden and tragic loss. Grief counselling and support is being offered to all employees and contractors at the mine.
