General Motors Holdings has agreed to form a joint venture with Lithium Americas for developing the latter’s Thacker Pass lithium project in Humboldt County, Nevada.

Canadian miner Lithium Americas said on Wednesday General Motors will contribute $625 million to their new joint venture for developing the Thacker Pass project in Nevada. U.S. automakers are ramping up their output of EVs and hybrids and aiming to reduce their reliance on China for battery-related materials in a competitive market.

For its 62% ownership of Thacker Pass, Lithium Americas will contribute $387 million to the JV and act as manager of the project.
