Chile Lithium Dispute Tied to Cold War-Era Nukes – by Tom Azzopardi (Mining.com – April 6, 2026)

Key Takeaways

• Eramet and ENAMI are litigating over Chile’s Salares Altoandinos lithium rights
• Project could supply lithium for ~1.5 million electric vehicles annually
• Development hinges on a Cold War‑era licence for nuclear‑grade lithium
• $3 billion investment with Rio Tinto may be postponed by legal fight
• Delay threatens Chile’s president’s growth agenda and global lithium supply

Pulse Analysis

Chile sits on roughly a quarter of the world’s lithium reserves, and the Salares Altoandinos deposit is poised to become a cornerstone of the country’s export strategy. With an estimated capacity to fuel 1.5 million electric vehicles per year, the $3 billion joint venture between state miner ENAMI and Rio Tinto promises to reshape the global battery supply chain. The project also aligns with President José Antonio Kast’s broader economic plan to diversify revenue beyond copper and attract high‑value manufacturing.

The legal battle stems from Chile’s 1970s legislation that classified lithium as a strategic material for nuclear weapons, requiring a special licence that has never been issued. Eramet acquired the mining rights in 2023 hoping to use its land position to negotiate a stake, but without the licence it cannot proceed. ENAMI argues the rights belong to the state, while Eramet seeks compensation or a partnership, pushing the dispute into the courts. This clash underscores how legacy policies can create uncertainty for investors in fast‑moving sectors like electric‑vehicle batteries.

If the court delays or blocks development, the ripple effects could be significant. Automakers may face tighter lithium supplies, prompting higher prices or a shift to alternative sources. For Chile, postponement would dent a flagship project meant to boost fiscal revenues and create skilled jobs, potentially slowing the nation’s transition to a green‑energy hub. Conversely, a resolution that clarifies licensing could unlock rapid expansion, reinforcing Chile’s role as a pivotal player in the global clean‑tech supply chain.
