Lithium Americas Confirms Oral Hearing Schedule for the Thacker Pass

Record of Decision Appeal

VANCOUVER, British Columbia, Oct. 07, 2022 -- Lithium Americas Corp. (TSX: LAC) (NYSE: LAC) (“Lithium Americas”

or the “Company”) provides an update on the appeal of the issuance of the Record of Decision (“ROD”) for the Thacker Pass

lithium project (“Thacker Pass” or the “Project”), located in Humboldt County, Nevada. Following the completion of briefings

on August 11, 2022, the US District Court, District of Nevada (“ Federal Court ”) has scheduled an oral hearing for January 5,

2023.

"With all state and federal permits received to begin construction, the ruling on Thacker Pass’ ROD represents the final

regulatory hurdle to move forward the largest and most advanced lithium chemicals project in the US,” said Jonathan Evans,

President and CEO. “We stand ready to develop a critical source of lithium supply, creating jobs and enabling a more

sustainable battery ecosystem in North America. As we await a ruling by the Federal Court, we are moving ahead with all

areas required to support construction, including final selection of an EPCM contractor, evaluating partnership and supply

agreements, as well as progressing our application with the US Department of Energy loan program.”

Since 2021, all four injunction requests related to the Company’s plan to begin cultural assessment required in the ROD were

denied by the Federal Court, and a subsequent motion to reconsider was also denied. In June 2022, the Nevada State

Environmental Commission unanimously upheld the Company’s approved Water Pollution Control Permit for Thacker Pass by

denying an appeal in a 5-0 ruling.

From April to July 2022, as part of the Environmental Impact Statement (“ EIS”) issued by the Bureau of Land Management

(“BLM”), analysis of the project site was successfully completed with no archeological significant areas identified at Thacker

Pass. The work, including a cultural inventory across approximately 13,000 acres, was conducted by Far Western

Anthropological Research Group, with the oversight and assistance of 11 members of the Fort McDermitt Paiute and

Shoshone Tribe (the “ Tribe”). Lithium Americas continues to work closely with the Tribe and is committed to providing

additional benefits and job training for long-term, highly skilled careers in the emerging North American battery supply chain.
