McEwen Inc. Reports Best Drill Hole to Date at Windfall Deposit, Advancing Gold Bar Mine Complex Toward Production

McEwen Inc. (NYSE: MUX) (TSX: MUX) announced new drill results from the Gold Bar Mine Complex in Nevada's Eureka Mining District, highlighted by the best hole drilled by the company to date at the Windfall deposit. The results returned 5.55 grams per tonne gold over 44.2 meters, including 48.38 grams per ton gold over 4.6 meters of oxide mineralization. Recent and historical results demonstrate strong grade continuity over long intervals and indicate that higher-grade mineralization remains open at depth.

The company plans drilling to test deeper extensions in March as Windfall, Lookout Mountain and Unity Ridge advance toward production. These developments support McEwen's strategy to double gold production by 2030. The company's gold and silver mines are located in prolific mineral-rich regions including the Cortez Trend in Nevada, USA, the Timmins district of Ontario, Canada and the Deseado Massif in Santa Cruz province, Argentina. McEwen is also considering reactivating a gold and silver mine in Mexico.

McEwen has a 46.4% interest in McEwen Copper, which owns the large, long-life, advanced-stage Los Azules copper development project in San Juan province, Argentina. According to the last financing for McEwen Copper, the implied value of McEwen's ownership interest is US$456 million. The Los Azules copper project is designed to be one of the world's first regenerative copper mines and carbon neutral by 2038.
