TORONTO, May 14, 2026 (GLOBE NEWSWIRE) -- McEwen Copper Inc. ("McEwen Copper" or the "Company") today announced that it has retained Societe Generale, to act as its sole financial advisor in connection with project debt financing of the Company's Los Azules copper project located in San Juan Province, Argentina (the "Project").

Under the mandate, Societe Generale will lead the structuring and arrangement of a senior debt package to fund the construction of the Project. Societe Generale's scope of work spans both preparatory and implementation phases and includes development of the financing strategy; coordination of lenders' technical, market, environmental and social, insurance, audit and tax due diligence; preparation of the lenders' information package; and assistance with the negotiation. The financing is expected to be assembled from a combination of export credit agency, commercial bank debt, multilateral and development finance institution facilities, and potential project bond or other capital markets instruments.

The appointment complements the Company's continuing relationship with the International Finance Corporation (IFC), a member of the World Bank Group, with whom the Company has a collaboration agreement to align the Project with IFC’s environmental, social, and governance standards in anticipation of international project financing. The Project will be developed in alignment with the Equator Principles.

"Bringing Societe Generale on board marks a significant step in advancing Los Azules toward construction," said Michael Meding, Managing Director of McEwen Copper. "Societe Generale's global project finance platform and long-standing relationships with the export credit agency, multilateral and commercial banking community make them an ideal partner to help us assemble a robust, competitively priced debt package for one of the world's largest undeveloped copper projects."

McEwen is also reactivating its gold and silver El Gallo Mine in Mexico.

The Company has a 46.3% interest in McEwen Copper, which owns the large, long-life, advanced-stage Los Azules copper development project in San Juan province, Argentina – a region that hosts some of the country’s largest copper deposits. 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. Its Feasibility Study results were announced in the press release dated October 7, 2025.

McEwen also recently purchased 27.3% of Paragon Advanced Labs Inc., a newly listed public company that is deploying PhotonAssay™ units around the world, a technology that McEwen believes is poised to become the new industry standard for assaying precious and base metals, with Paragon aiming to be one of the leading service providers.
