Chinese investment in Argentina’s lithium sector continues to expand, highlighted by China Union Holdings’ recent $175 million acquisition of Argentum Lithium, a subsidiary of Canadian Lithium Chile, which controls significant stakes in the Arizaro salar in Salta. This deal forms part of broader Chinese capital commitments nearing $3.4 billion across seven lithium projects in Northwest Argentina, positioning China as a dominant player securing long-term supply for battery and electric vehicle industries.
China Union Holdings agreed to purchase 100% of Argentum Lithium, which controls key lithium mining rights in the Arizaro salar, one of Argentina’s largest lithium salt flats. Arizaro’s annual production capacity is estimated at 25,000 tons of battery-grade lithium carbonate, supported by resource studies and prefeasibility evaluations. The $175 million transaction comprises a 92.5% payment at closing, a $5 million deposit guarantee, and a retained escrow of 7.5% for 18 months to cover potential contingencies. Preceding conditions mandate Argentum to increase its stake in ARLI S.A., the controlling entity of the salar’s mining rights, to 80%. Failure to close within 180 days or meet contractual terms triggers penalties up to $17.5 million, underscoring deal complexity. Lithium Chile’s CEO, Steve Cochrane, framed the deal as an opportunity to realize value in Argentina while refocusing resources on Chile.
China’s growing dominance in Argentina’s lithium sector aligns with investments by firms like Ganfeng Lithium and Zijin Mining, targeting projects in Jujuy, Salta, and Catamarca. Major Chinese ventures include Tibet Summit Resources’ $2.2 billion investment in Salar Arizaro and Salar Diablillos and Tsingshan Holding’s $890 million commitment for the Salar Centenario-Ratones project and processing plant. Collectively, Chinese-backed projects aim to produce over 170,000 tons annually within the next few years.
Argentina, part of the global “Lithium Triangle” alongside Chile and Bolivia, holds roughly 20 million tons of lithium resources. The lithium mining industry there benefits from lower extraction costs due to salar brine deposits. However, Chinese firms reportedly pursue majority control over mining assets, supported by preferential financing from Chinese state banks and leveraging strategic political relationships. This extensive presence enables China to secure a dominant role in the global lithium supply chain amid accelerating demand for electric vehicle batteries.
