Argentina, Brazil, Chile, and Peru have signed a cooperative pact on strategic minerals, aiming to coordinate the region's lithium, copper, and rare earth deposits rather than leave them as separate national operations. The deal builds on existing cross-border treaties and arrives as the US and EU push to reduce reliance on Chinese minerals processing.
Four South American countries have signed a cooperative pact on strategic minerals, marking a formal step toward turning the continent's lithium, copper, and rare earth deposits into a coordinated asset rather than a collection of separate mining operations. The agreement involves Argentina, Brazil, Chile, and Peru.
What the pact covers
The deal builds on months of cooperation across the region. Argentina and Chile have been advancing operational protocols for cross-border copper projects under their revived 1997 Mining Integration and Complementation Treaty. That effort alone could unlock $20.7 billion in investments and boost annual copper output by 540,000 tonnes.
Brazil has built its own parallel track. On August 6, Brazil's Ministry of Mines and Energy formalized a technical cooperation agreement with the Development Bank of Latin America and the Caribbean, known as CAF, to study regional integration of critical minerals supply chains across the Mercosur bloc and Chile. Peru rounds out the quartet, with its mining industry associations taking part in discussions about shared strategies, a topic at the PERUMIN mining symposium in May.
The geopolitical stakes
The US signed supply-chain frameworks with Argentina, Chile, Paraguay, and Peru back in February as part of a broader push to cut dependency on Chinese minerals processing, since Beijing dominates refining and processing even when raw materials originate elsewhere. Nations increasingly want to source from allies rather than rivals, an approach often called "friend-shoring," and both the US and the EU have adopted policies that incentivize it.
Meanwhile, the Lithium Triangle, comprising Argentina, Bolivia, and Chile, holds more than 50% of the world's known lithium reserves, material essential for batteries in electric vehicles and grid-scale energy storage.
Risks to execution
Cross-border protocols between Argentina and Chile mean copper projects straddling the Andes could move forward at scale, and Brazil's CAF agreement adds an institutional layer that could accelerate financing for regional projects. However, execution remains the central risk with multilateral agreements in the region: Argentina's economic volatility, Brazil's shifting regulatory landscape, and Peru's history of mining protests all remain potential friction points.
