Swiss Mining Giant Glencore Bets on Argentine Copper With Alumbrera Restart Targeted for 2028

Swiss mining giant Glencore is reinforcing its commitment to Argentina’s copper industry with plans to reactivate the Alumbrera project by 2028, positioning the country as a key future supplier of strategic minerals for the global energy transition.

The move reflects growing international interest in Argentina’s mining potential, particularly in copper, a metal considered essential for electric vehicles, renewable energy infrastructure and global electrification.

Alumbrera, one of Argentina’s most emblematic mining projects, had ceased operations years ago following the depletion of reserves and changing market conditions. Its planned return now signals renewed confidence in both copper prices and the country’s long-term resource potential.

For Glencore, the strategy aligns with a broader global shift among major mining companies toward critical minerals linked to decarbonization and industrial transformation. Copper demand is expected to surge over the next decade as governments and industries accelerate investments in clean energy technologies.

Argentina is increasingly emerging as a strategic destination within that landscape. The country combines significant geological potential with growing interest from international investors seeking diversified sources of supply outside traditional mining hubs.

The development also strengthens the role of provinces such as Catamarca and San Juan within South America’s mining ecosystem. Large-scale projects are expected to generate employment, infrastructure development and export growth while attracting additional exploration activity.

For Europe, Argentina’s copper sector is becoming increasingly relevant as the continent seeks secure access to critical raw materials. Diversifying supply chains away from concentrated producers has become a strategic priority amid geopolitical tensions and growing industrial demand.

At the same time, mining expansion in Argentina continues to face challenges linked to infrastructure, regulation, environmental standards and community relations. Sustainability and social license remain critical factors for the viability of future projects.

The Alumbrera restart is part of a wider transformation underway in the mining industry, where Latin America is gaining strategic importance in the global competition for resources needed for electrification and energy security.

Glencore’s renewed bet on Alumbrera underscores Argentina’s growing role in the global copper market and highlights how critical minerals are reshaping investment flows between Europe and Latin America.
