LAC Lithium Americas Corporation

Lithium Americas Corp. (TSX: LAC) (NYSE: LAC) (“Lithium Americas” or the “Company”) is pleased to announce the commencement of construction at its 100%-owned Thacker Pass lithium project (“Thacker Pass” or the “Project”) in Humboldt County, Nevada, following the receipt of notice to proceed from the Bureau of Land Management (“BLM”).

“Starting construction is a momentous milestone for Thacker Pass and one we have been working towards for over a decade,” said Jonathan Evans, President and CEO. “We are excited about the prospect of generating economic growth in Northern Nevada and playing a major role in the domestic lithium supply chain for electric vehicles.”

Thacker Pass is targeting 80,000 tonnes per annum (“tpa”) of battery-quality lithium carbonate (“Li2CO3”) production capacity in two phases of 40,000 tpa, respectively (“Phase 1” and “Phase 2”). Phase 1 production is expected to commence in the second half of 2026. The Project is expected to create 1,000 jobs during construction and 500 jobs during operations. Further information can be found in the technical report titled “Feasibility Study, National Instrument 43-101 Technical Report for the Thacker Pass Project Humboldt County, Nevada, USA” with an effective date of November 2, 2022 (the “Technical Report”), filed on SEDAR under the Company’s profile on January 31, 2023.

Construction at Thacker Pass commenced following the favorable ruling from the US District Court, District of Nevada (“Federal Court”) for the issuance of the Record of Decision (“ROD”), where the Federal Court confirmed the permitting process for Thacker Pass was conducted thoroughly and responsibly. The Federal Court declined to vacate the ROD and ordered the BLM to consider one issue under the mining law relating to the area designated for waste storage and tailings and did not impose any restrictions expected to impact the construction timeline. The Company is working closely with the BLM to complete the required follow-up and does not expect it to impact the overall construction timeline.
