Rio Tinto is considering increasing its stake in the Los Azules copper project in Argentina. The project is regarded as one of the world’s largest undeveloped copper deposits and is expected to begin production in 2030, with average annual copper cathode output estimated at approximately 204,800 mt during its first five years of operation. Rio Tinto currently holds around 17.2% of project developer McEwen Copper through its Nuton venture, while Stellantis is also among the project’s key shareholders. Market attention remains focused on major mining companies continuing to strengthen investments in high-quality global copper resources.
