Lanshen Brings Cash and Tech to Salta Lithium Project

Argentina Lithium secures a $100 million partnership with Lanshen to deploy advanced extraction technology at the Rincon West project in Salta

21 Apr 2026

The race for white gold in South America just got a massive injection of capital and chemistry. Argentina Lithium & Energy Corp. has inked a $100 million framework deal with Xi’an Lanshen New Material Technology to fast-track the Rincon West project in Salta Province. This partnership signals a shift toward Direct Lithium Extraction (DLE), a technology promised to be faster and more efficient than traditional evaporation ponds.

Lanshen is not just bringing cash to the table; it is buying a seat at the helm. The Chinese tech firm can earn a 30 percent stake in the local subsidiary by hitting specific targets. The plan moves through three distinct phases, starting with pilot testing before diving into full-scale engineering and environmental permitting.

The heavy lifting happens in the final stage, where Lanshen will deploy nearly $96 million to build a commercial facility. This turnkey plant aims to pump out 5,000 tonnes of battery-grade lithium carbonate annually. It is a bold play in a competitive region, especially with automotive giant Stellantis already holding a roughly 20 percent slice of the venture.

By replacing a preliminary memorandum from late 2025, this agreement turns vague intentions into a roadmap for production. While the deal still faces the usual hurdles of due diligence and regulatory stamps, the momentum is undeniable. Salta is quickly becoming the epicenter of the next lithium wave.

This investment underscores Argentina's growing dominance in the Lithium Triangle. As neighbors like Rio Tinto develop adjacent plots, Rincon West is no longer just a prospect on a map. It is now a fully funded laboratory for the future of battery supply chains.
