Rio Tinto Eyes Bigger Stake in Los Azules Copper Project

Key Developments

Mining giant Rio Tinto is evaluating an increase to its 17.2% stake in McEwen Copper’s Los Azules project in Argentina. Los Azules ranks among the world's ten largest undeveloped copper projects, signaling a strategic move to secure future supply.

Market Context

The consideration comes as global miners race to acquire large-scale copper assets to meet surging demand driven by data centers and the clean energy transition. Rio Tinto's technical team is assessing the project's economic potential while testing its proprietary Nuton leaching technology on-site to optimize copper recovery.

Financial Implications

The Los Azules project holds an estimated after-tax net present value of $2.9 billion. McEwen Copper is seeking approximately $4 billion in initial capital for development, with first production targeted for 2030. A larger investment from Rio Tinto would be a significant step toward financing the project.

Summary and Outlook

Securing a larger share of Los Azules would significantly strengthen Rio Tinto’s copper pipeline in a highly competitive market. Industry stakeholders are closely watching the ongoing discussions, as the outcome will influence the project's development timeline and Rio’s long-term production profile.
