McEwen Mining Reports Q2 2019 Production Results

TORONTO, July 17, 2019 - McEwen Mining Inc. (NYSE: MUX) (TSX: MUX) reports consolidated production for Q2 2019 of 36,216 gold ounces and 850,525 silver ounces, or 45,881 gold equivalent ounces⁽¹⁾ (“GEOs”) using the average gold:silver price ratio during Q2 of 88:1. Our San José and El Gallo mines, which accounted for 62% our total gold and silver production in Q2, exceeded our targets. Our other two operations, the Gold Bar and Black Fox mines, performed better than in Q1, but below our forecast. Looking ahead, our production guidance for the year 2019 has been reduced by 6% for gold and is unchanged for silver. On a gold equivalent basis, silver is forecast to represent 20% of our 2019 consolidated production of 190,000 GEOs.

Rob McEwen, Chairman and Chief Owner commented: “The big events in Q2 were achieving commercial production at Gold Bar in late May and the high-grade exploration results from the Black Fox properties. Production results in the quarter were mixed. San José and El Gallo, which accounted for 62% of our Q2 production, performed well this quarter. At Gold Bar and Black Fox, we have had our head down and were pushing hard all quarter long. While both mines delivered better production in Q2 than in Q1, we didn’t achieve our forecast numbers. As a result, we have reduced our 2019 production guidance for gold by 6%.”

Gold Bar Mine, Nevada (100%)

Commercial production was achieved at Gold Bar on May 23, 2019. Gold Bar produced 7,940 gold ounces in Q2. The ramp-up to full production is progressing but the delays in Q1 adversely impacted our gold production in Q2 and our forecast for 2019.

In essence, less ore was placed onto the heap leach pad than planned, which in turn has delayed the application of solution to the ore, and subsequently the recovery of gold. Gold production is increasing, and we expect much better performance in the second half of 2019. Ore grade and tonnage are reconciling positively to our block model, and the gold recovery curves are tracking well compared to our budget.

Our revised plan is to produce 15,000 gold ounces in Q3 and 17,000 gold ounces in Q4. Guidance for 2019 has been reduced from 50,000 to 42,000 gold ounces as a result of the slower than expected ramp-up.

Our 2019 exploration budget for the Gold Bar property is $5 million. Drilling started mid-May with an initial focus on Gold Bar South in order to provide data necessary to advance economic studies and permitting. Our objective is to incorporate Gold Bar South into the mine plan this year and have permitting in place so that development could begin in late 2020. Starting in July, drilling will be testing the deep potential of the property for Carlin-type gold deposits.

Black Fox Mine, Timmins, Canada (100%)

Black Fox produced 9,420 gold ounces in Q2. Production was adversely affected by water infiltration into the mine due to an unusually heavy spring run-off. In order to protect the main infrastructure of the underground operation, the western part of the mine was allowed to flood temporarily. This action reduced production by limiting access to some areas where Q2 production was planned. As a result, production guidance for 2019 has been reduced from 50,000 to 45,000 gold ounces.

Our 2019 exploration budget for the Black Fox Complex is $18 million and includes surface and underground drilling. Drilling started in April and there are currently 10 surface drill rigs and one dedicated underground drill rig actively exploring on the Black Fox and Stock properties.

On May 23, 2019 we released very positive gold drill results from the Black Fox Mine and promising intersections in the Grey Fox Area. We followed up with more high-grade drill result from Grey Fox 147NE Target on July 10, 2019, see news release: https://www.mcewenmining.com/investor-relations/press-releases/press-release-details/2019/McEwen-Mining-Exploration-Drives-a-Potential-New-Source-of-Production/

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

The San José mine is on-track to achieve our full year guidance for 2019 of 49,000 gold ounces and 3,225,000 silver ounces. Our attributable production from San José in Q2 was 13,518 gold ounces and 848,268 silver ounces, for a total of 23,158 GEOs.

El Gallo Project, Sinaloa, Mexico (100%)

Based on the improved leaching performance from process plant modifications completed in Q2, we are increasing our full year guidance for 2019 at El Gallo to 16,000 gold ounces from residual leaching. El Gallo produced 5,340 gold ounces in Q2.

Fenix Project

Work on the Fenix Project feasibility study and permitting is progressing. We expect the permit to be approved and the feasibility study to be completed in Q3 2019.

Second Quarter Financial Results

Operating costs for the quarter ended June 30, 2019 will be released with our 10-Q Quarterly Financial Statements at the end of July.
