TORONTO, July 25, 2018 (GLOBE NEWSWIRE) — McEwen Mining Inc. (NYSE:MUX) (TSX:MUX) reports additional encouraging exploration results from its ongoing $15 million exploration program at the Black Fox Complex near Timmins, Ontario, Canada.

McEwen’s 2018 exploration goals are to grow known deposits and make new discoveries to contribute to near-term gold production. During Q2 a total of 129,000 ft (39,300 meters (m)) of surface exploration drilling was completed at Black Fox Complex, for a year-to-date total of 220,000 ft (66,900 m).

“Our drilling continues to deliver very encouraging results, particularly from the three project areas highlighted in this release: Stock East, Froome and Gibson. Continued drilling success reinforces our view about the strong exploration potential of both the Black Fox and Stock properties,” stated Sylvain Guerard, Senior Vice-President Exploration.

Three of our exploration targets are covered in this release: Stock East, Froome and Gibson. Underground delineation drilling intercepts from Black Fox are also included, along with a revised Black Fox Mine resource estimate, which eliminates the Inferred resource category and increases the Indicated ounces and grade.

Stock East

The Stock Mine property covers a 4 mile (6.5 km) section of the Destor-Porcupine fault, and produced 137,000 gold ounces at a grade of 5.5 g/t between 1989 and 2005. Our winter drilling program was designed to follow-up on historical intersections and geophysical targets; it returned better than expected results at the Stock East target and prompted an expanded 66,000 ft (20,000 m) drilling program beginning in early June. Three drill rigs are currently active and will infill the Stock East target, test the depth extension of the Stock Mine below 500 m, and attempt to join mineralization at Stock East with the historical Stock Mine over a 2,000 m long trend (see Figure 1).

Stock East has a strike length of approximately 500 m and extends vertically from surface to a depth of at least 450 m. Its proximity to our mill facility makes Stock’s potential for an open-pittable deposit a particularly attractive target.

Froome

The Froome deposit is located 2,800 ft (850 m) to the West of the Black Fox open pit. It was discovered in 2014 and has a current Indicated resource of 159,000 gold ounces at a grade of 5.26 g/t.
Drilling at Froome during Q2 has identified a mineralized structure in the footwall, approximately 150 m North of the Main Froome Deposit (see Figure 2). The gold-bearing trend hosts clusters of positive drill intersections at Froome Northwest, North and Southeast that may lead to the definition of additional zones of mineralization proximal to the Froome Deposit. In addition, new drill intersections below the Froome Deposit suggest some incremental resource expansion potential. The potential to develop underground access to the Froome Deposit through mineralization in the footwall could provide a major enhancement to the project’s economics and will be evaluated once drilling to better define the zones is complete.
Footwall drilling highlights include the following intersections:
19.42 g/t gold over 2.5 m, including 52.7 g/t gold over 0.83 m at the Footwall NW area;
7.97 g/t gold over 5.99 m at the Footwall North area; and
7.91 g/t gold over 3.12 m, including 13.9 g/t gold over 1.56 m at the Footwall SE area.
Drilling down-dip of the Froome Deposit encountered 4.04 g/t gold over 7 m, suggesting the mineralization continues at depth. Drilling at Froome will continue in Q3 to follow up on these results.

Gibson

The Gibson exploration target area is adjacent the Grey Fox Deposit, where Indicated resources of 465,000 gold ounces at a grade of 6.64 g/t, and Inferred resources of 100,000 gold ounces at 6.83 g/t are currently defined.
The present dimensions of the Gibson Zone mineralization are approximately 100 m in length along strike and 400 m depth from near surface. Additional drilling is underway to better define the extent and orientation of the mineralization.
Hole 18GF-1079 returned 3.11 g/t gold over 34 m (core length), including 10.81 g/t gold over 6 m, from a new style of breccia mineralization identified at the Gibson area. This new intersection suggests the potential for extension of the mineralization to a 500 m depth below surface. Drilling will continue in Q3 to further assess the potential depth extension.
