GM and Lithium Americas to develop lithium production through $650-million investment

General Motors and Lithium Americas plan to jointly invest in the development of the Thacker Pass mine in Nevada, which the companies call “the largest known source of lithium in the US.” GM plans to use lithium carbonate from Thacker Pass in its proprietary Ultium battery cells. 

As part of the deal, GM will make a $650-million equity investment in Lithium Americas.

Lithium Americas estimates that the lithium extracted and processed from the project will be enough to equip roughly 1 million EVs per year.

“GM has secured all the battery material we need to build more than 1 million EVs annually in North America in 2025 and our future production will increasingly draw from domestic resources like the site in Nevada we’re developing with Lithium Americas,” says GM CEO Mary Barra. “Direct sourcing of critical EV raw materials and components from suppliers in North America and free-trade-agreement countries helps make our supply chain more secure, helps us manage cell costs, and creates jobs.”

“The agreement with GM is a major milestone in moving Thacker Pass toward production, while setting a foundation for the separation of our US and Argentine businesses,” said Lithium Americas President and CEO Jonathan Evans. “This relationship underscores our commitment to develop a sustainable domestic lithium supply chain for electric vehicles.”

Production at Thacker Pass is projected to begin in the second half of 2026.
