TORONTO, July 16, 2020 (GLOBE NEWSWIRE) — McEwen Mining Inc. (NYSE: MUX) (TSX: MUX) reports consolidated production for Q2 2020 was 15,700 gold ounces and 359,400 silver ounces, or 19,200 gold equivalent ounces⁽¹⁾(“GEOs”), at the average gold:silver price ratio for the quarter of 104:1. Production was significantly impacted by temporary mine suspensions at all four of our operations as a result steps taken to stop the spread of COVID-19, along with operational issues at several mines. 

Consolidated Production Summary

Black Fox Mine, Timmins, Canada (100%)

In Q2, Black Fox produced 2,200 GEOs. Mining was temporarily suspended at Black Fox from March 26^th to April 13^th due to health and safety concerns resulting from the COVID-19 pandemic. A progressive return to work was completed by the end of April. For the remainder of the quarter production was lower due to lower than expected grade and development work completed for establishing a greater number of mining areas in order to improve operational flexibility.

Development of the access to the Froome deposit is on track, having advanced 30% of the way to the orebody. The plan is to reach the orebody in Q2 2021, complete the necessary development and start production from Froome in Q4 2021.

At the Black Fox Mine, a total of 44,800 feet (13,650 m) of underground diamond drilling was completed between April 13^th and June 30^th, with 70% devoted to closely spaced definition drilling of gold mineralization within or adjacent to upcoming mining blocks (see Figure 1). Exploration is continuing on the upper west flank of the mine. During H1, this area has delivered some impressive high grade results. For details please refer to our news release dated June 17th, 2020 – Click here).

High-grade intercepts were generated from these ore definition holes, including:

• 42.2 g/t Au over 2.0 m from hole 660-F953-13
• 42.4 g/t Au over 2.5 m from hole 260-B242-07A
• 20.9 g/t Au over 4.8 m from hole 260-B249-09

San José Mine, Santa Cruz, Argentina (49%⁽²⁾)

In Q2, San José produced 5,500 gold ounces and 358,700 silver ounces, for a total of 9,000 GEOs. Mining was temporarily suspended from March 20^th due to a nationwide mandatory quarantine imposed in Argentina to combat the spread of COVID-19. Although the mine was able to restart operations in late April, the operations remain below capacity due to government imposed travel restrictions that continue to pose significant challenges in mobilizing personnel to the site.

Gold Bar Mine, Nevada (100%)

In Q2, Gold Bar produced 6,100 GEOs. Mining was halted on April 1^st due to concerns about the COVID-19 pandemic, and production ramp up started on May 4^th. Throughout May and June the mine only operated on day shift as work progressed for the updated resource model, new mine plan and addressing engineering design deficiencies. Full operations on day and night shift are scheduled to start in August.

Pit optimizations are ongoing and detailed mine planning is underway. Completion of a new resource estimate, mine plan and 2020 forecast are being finalized in Q3. A new reserve estimate is expected towards the year’s end.

Drilling on Gold Bar South is testing for extensions of the deposit. Drilling on the south extension encountered significant mineralization, indicating the potential to extend the existing resource to the south (see Figure 2), including:

• Two holes drilled 100 ft (30 m) from the latest mineralized drill fence returned: 1.2 g/t Au over 125 ft (Hole GBS079) and 0.9 g/t Au over 150 ft including 4.0 g/t Au over 10 ft (Hole GBS080); and
   
• Partial results from drilling completed 100 ft (30 m) further to the south returned 1.5 g/t Au over 70 feet (Hole GBS113).

El Gallo Project, Sinaloa, Mexico (100%)

In Q2, El Gallo produced 1,900 GEOs from residual leaching of the heap leach pad. COVID-19 is an ongoing challenge in Sinaloa. We are saddened to report that some employees and contractors at the mine and regional office have contracted the virus. One of our employees, who seemed to be recovering well in hospital, passed away suddenly due to complications. We are supporting all the families in this difficult time and extend our sincere condolences on the loss of our valued team member. No severe symptoms have been reported among the other confirmed or suspected cases.
