McEwen Mining Drills 53 g/t Gold Over 6.7 m at Grey Fox

TORONTO, Feb. 05, 2020 (GLOBE NEWSWIRE) -- McEwen Mining Inc. (NYSE: MUX) (TSX: MUX) is pleased to report additional positive drill results from the Whiskey Jack target in the Grey Fox area, part of the Black Fox Complex, located in the prolific Timmins gold district, Canada.

Sylvain Guerard, SVP Exploration commented: “New intersections at Whiskey Jack have confirmed high‑grade gold mineralization over significant true widths, including 53 g/t Au over 6.7 m. This intersection is open and offers good potential for the discovery of a new high-grade deposit, that could contribute to the growth of our existing resource at Grey Fox.”

The Whiskey Jack target is located on the northern extension of the Grey Fox mineralized system (see Figure 1), where the contact between sedimentary and volcanic units changes orientation, from a steep dip to the east to a moderate dip to the southwest. Mineralization at Whiskey Jack is known to have complex geometry, but recent drilling has better defined the important geologic controls.

Hole 19GF-1293 (see Figure 2) was drilled to assess the true width of an earlier 9.0 g/t Au over 44 m core length intersection released on December 3, 2019, which was believed to have been drilled at a low angle to the mineralized structure, and is now interpreted to have a true width of 4.9 m. Results from hole #1293 returned two sub-parallel intersections of 5.8 g/t Au over 4 m and 53 g/t Au over 6.7 m, confirming the initial interpretation and the consistency of the broad high-grade mineralization in this system (see Table 2 for detailed assays for hole #1293).
