Lithium Americas Corp. Completes Acquisition of Millennial Lithium Corp.

VANCOUVER, Jan. 25, 2022 - Lithium Americas Corp. (TSX: LAC) (NYSE: LAC) ("Lithium Americas" or the "Company") and Millennial Lithium Corp. ("Millennial") are pleased to announce the completion of the previously announced plan of arrangement (the "Arrangement") whereby Lithium Americas has acquired all of the issued and outstanding shares of Millennial. Millennial owns 100% of the Pastos Grandes lithium brine project ("Pastos Grandes" or "Project") in Salta, Argentina.

Pursuant to the Arrangement, Lithium Americas has acquired 100% of the issued and outstanding shares of Millennial ("Millennial Shares") and Millennial shareholders are entitled to receive 0.1261 of a common share of Lithium Americas and $0.001 in cash in exchange for each Millennial Share held immediately prior to closing of the Arrangement. The share ratio was calculated by valuing the Lithium Americas shares at a price equal to the volume-weighted average share price of Lithium Americas for the 20 trading days ending two business days prior to closing, and by valuing the Millennial common shares at a price of C$4.70 per share. In aggregate, the Company issued approximately 13,200,000 Lithium Americas common shares under the Arrangement to former Millennial securityholders as consideration for their respective Millennial Shares and convertible securities.

As a result of the Arrangement, the Millennial Shares and warrants to purchase Millennial Shares are anticipated to be de-listed from the TSX Venture Exchange on or about January 26, 2022.

"With the completion of the acquisition, we have greatly strengthened our asset base and growth pipeline in Argentina," said Jonathan Evans, President and CEO of Lithium Americas. "While our near-term focus remains on bringing Cauchar?-Olaroz into production, the additional resources at Pastos Grandes provides the potential to support district-scale development to meet rising demand from the industry."

Pastos Grandes is an advanced stage lithium brine project located in the Salta Province, Argentina, approximately 100 kilometers from Cauchar?-Olaroz. The Project completed a feasibility study in 2019 based on a production capacity of 24,000 tonnes per annum ("tpa") of lithium carbonate and received the environmental impact assessment for construction and operations in 2020. Lithium Americas has started to integrate and expand the Project team in Salta and looks to leverage the Company's experience and learnings from development of Cauchar?-Olaroz. Over the coming months, the Company will provide details around the development plan, which will consider alternatives to improve and de-risk the 24,000 tpa production plan proposed in the 2019 feasibility study.

Greenhill & Co. Canada Ltd. acted as financial advisor to Lithium Americas, and Cassels Brock & Blackwell LLP acted as Lithium Americas' legal advisor.
