Vancouver-based Lithium Americas said on Wednesday that the US Department of Energy (DOE) has taken a 5% stake in the company, along with a separate 5% stake in its Thacker Pass lithium project joint venture with General Motors.
While the total deal value was not disclosed, Lithium Americas confirmed it has finalized an agreement with the DOE to initiate the first $435 million draw from a previously announced $2.26 billion loan to support development of the Thacker Pass site.
It will be the latest private sector investment by US President Donald Trump's administration after recent stakes in Intel and MP Materials, seeking to boost industries seen as vital to US national security.
The Thacker Pass project has long been touted by both Republicans and Democrats as a key way to boost US critical minerals production and cut reliance on China, the world's largest lithium processor.
China's influence is far greater in refining, where it processes over 75% of the world's lithium into battery-grade material.
The US produces less than 5,000 metric tons of lithium at a Nevada facility owned by Albemarle. Thacker Pass's first phase is expected to produce 40,000 metric tons of battery-quality lithium carbonate per year, enough for up to 800,000 EVs.
General Motors, which invested $625 million in the mine last year for a 38% stake, has the right to buy all of the project's lithium from its first phase and a portion from the second phase for 20 years.
