On September 24, 2025, the International Finance Corporation (IFC) and McEwen Copper Inc., a subsidiary of McEwen Inc., signed a collaboration agreement to align the Los Azules copper project with IFC’s ESG performance standards. The agreement will support the project’s pursuit of future debt and equity financing and de‑risk the investment for international lenders.
Los Azules, located in San Juan province, Argentina, has already secured an Environmental Impact Declaration and is scheduled to complete its feasibility study in October 2025. The project’s preliminary economic assessment estimates a $2.7 billion after‑tax NPV at a discount rate of 8 % and a 27‑year mine life, with 10.9 billion pounds of indicated copper at 0.40 % and 26.7 billion pounds of inferred copper at 0.31 %.
Company executives highlighted the strategic importance of the partnership. Rob McEwen, Chairman and Chief Owner, said the collaboration “will help us align with top‑tier sustainability standards while paving the way for IFC as a potential lead lender and equity partner, driving value for shareholders.” Michael Meding, VP & General Manager of McEwen Copper, added that embedding IFC’s performance standards will bolster the project’s appeal to global investors and support Argentina’s mining sector.
