General Motors is investing $625 million in the Thacker Pass lithium mine in Nevada through a joint venture with Lithium Americas, aiming to strengthen its electric vehicle supply chain. This investment replaces a previous agreement and follows an initial $320 million investment. GM plans to purchase up to 100% of production during the mine’s first phase for 20 years and 38% for another 20 years in the second phase. The mine, touted as North America’s largest lithium deposit, is expected to start production by late 2027, targeting 40,000 tons of battery-grade lithium carbonate annually.
