(NYSE/TSX: MUX) (“McEwen” or the “Company”) is pleased to announce that the extension of its Environmental Impact Assessment (Manifestación de Impacto Ambiental) for the El Gallo Mine has been granted by the Mexican government. This approval is a critical step that will allow McEwen to begin Phase 1 Mill Construction. The Company is targeting mid-2026 for construction start, and mid-2027 for its first gold pour. McEwen has purchased the ball mill, which is onsite at the mine. The Company has also started work on Phase 2, which will involve production from the project’s in-situ silver deposits. This could extend the life of El Gallo well beyond the initial 10 years contemplated under Phase 1.

Production will come from reprocessing the material from the historical leach pad. Remaining capital costs to complete construction are estimated at $25 million. Since the material to be processed was previously mined, no significant development or exploration costs are anticipated, enhancing free cash flow.Get the latest headlines, breaking news and columns.By signing up you consent to receive the above newsletter from Postmedia Network Inc.A welcome email is on its way.

Resources were calculated using a silver price of $28.50 per ounce and a gold price between $950 and $1,500 per ounce. This estimate is historical in nature; a qualified person has not done sufficient work to classify the historical estimate as current mineral resources and should therefore not be relied on or considered as current. The Company will be updating the resource estimates for El Gallo in 2026, based on the currently known resource areas.About McEwenMcEwen shares trade on both the NYSE and TSX under the ticker MUX.McEwen provides its shareholders with exposure to a growing base of gold and silver production in addition to a very large copper development project, all in the Americas.
