McEwen Copper Closes ARS $42 Billion Investment by Stellantis

TORONTO, Oct. 11, 2023 (GLOBE NEWSWIRE) -- McEwen Copper Inc., a subsidiary of McEwen Mining Inc. (NYSE: MUX) (TSX: MUX), is pleased to announce the closing of an additional ARS $42 billion investment by Stellantis, one of the world’s leading automakers and mobility providers with iconic brands including Abarth, Alfa Romeo, Chrysler, Citroën, Dodge, DS Automobiles, Fiat, Jeep^®, Lancia, Maserati, Opel, Peugeot, RAM, Vauxhall, Free2Move and Leasys.

Stellantis N.V. (“Stellantis”), which in February 2023 invested ARS $30 billion, has today invested an additional ARS $42 billion in Argentina to acquire shares of McEwen Copper in a private placement of 1,900,000 common shares. The proceeds of the private placement will be used to advance development of the Los Azules copper project in San Juan, Argentina, and for general corporate purposes.

Giving effect to the pending investment by Nuton LLC, also announced today, Stellantis increases its ownership to 19.4% of McEwen Copper and McEwen Mining owns 47.7% on a fully diluted basis. The Transaction values McEwen Copper at approximately US$800 million.

In connection with the Transaction, McEwen Copper and certain of its affiliates amended the Investor Rights Agreement with Stellantis (the "Stellantis IRA”) and the Copper Cathodes and Concentrates Purchase Rights Agreement (the “CCCPRA”), further described below.

The Stellantis IRA was amended to make the Carbon Neutral Commitment by 2028 not contingent on Stellantis maintaining a certain minimum ownership percentage in McEwen Copper. McEwen Copper intends to implement this commitment independent of Stellantis’ involvement in the Los Azules project.

The CCCPRA was amended to provide for a minimum 10,000 tonne per annum copper cathode offtake, subject to certain restrictions and exclusions, and further defined ‘market price’ to be paid by Stellantis on future copper cathode purchases pursuant to the CCCPRA.

This press release shall not constitute an offer to sell or the solicitation of an offer to buy, nor shall there be any sale of these securities in any jurisdiction in which such offer, solicitation or sale would be unlawful.
