TORONTO, May 27, 2024 (GLOBE NEWSWIRE) -- McEwen Mining Inc. (NYSE: MUX) (TSX: MUX) is pleased to provide new assay results from the Grey Fox deposit, part of our Fox Complex. The results in Table 1 demonstrate intriguing explorations targets at depth and attractive near surface gold grades with potential to be recovered utilizing lower cost open pit mining methods.

Gold at Grey Fox has been found in multiple zones, including Gibson, Whiskey-Jack, 147 and Grey Fox South (GFS). The current resource estimate for Grey Fox is 1,168,000 oz gold at a grade of 4.80 g/t Au Indicated and 236,000 oz gold at 4.35 g/t Au Inferred. An updated resource estimate will be completed in late September. Much of the drilling performed in 2023 and continuing into 2024 was focused on increasing the existing resource in addition to identifying new mineralized horizons.

Geological interpretations suggest that Grey Fox sits stratigraphically above the mineralization of the Black Fox & Froome mines. Consequently, there is potential for deeper Black Fox & Froome style mineralization directly below some of the Grey Fox zones. Historical production from these two mines is more than 1,000,000 oz gold.

Figure 1 shows the location of the Grey Fox zones relative to the Black Fox and Froome mines, on the same large property, separated by approximately 3 kilometers (1.9 miles). There has been limited drilling between Black Fox and Grey Fox, despite historical drill results that indicate similar rock types associated with the A1 Fault, the principal structure that controls the mineralization at Black Fox.
