Lithium Americas Announce FID for Thacker Pass Phase 1 and Closes

Strategic Investment from Orion Resource Partners

(All amounts in US$ unless otherwise indicated)

VANCOUVER, British Columbia--(BUSINESS WIRE)--April 1, 2025--Lithium Americas

Corp. (TSX: LAC) (NYSE: LAC) (“Lithium Americas” or the “Company”) today announced

the closing of the previously announced $250 million investment from fund entities managed by

Orion Resource Partners LP (collectively, “Orion”), for the development and construction of

Phase 11 of the Thacker Pass lithium project in Humboldt County, Nevada (“Thacker Pass” or

the “Project”). Contemporaneously, Lithium Americas and General Motors Holdings LLC

(“GM”) (together, the Thacker Pass joint venture (“JV”) partners (“JV Partners”)) announced

the final investment decision (“FID”) for Thacker Pass Phase 1.

HIGHLIGHTS

 As part of closing, Orion has purchased senior unsecured convertible notes in the

aggregate principal amount of $195 million, has paid Lithium Americas $25 million in

exchange for payments corresponding to the minerals produced and gross revenue

generated by Thacker Pass and committed an additional $30 million in aggregate

principal amount of senior unsecured convertible notes available through a delayed draw

facility, subject to the satisfaction of certain conditions (the “Investment”).

 The Investment satisfies all remaining requirements from both the U.S. Department of

Energy (“DOE”) and GM to satisfy all remaining equity capital fundraising requirements

under the previously announced $2.26 billion loan from the DOE (the “DOE Loan”).

 With the Investment, Lithium Americas has achieved fully funded status for the

development of Phase 1 of Thacker Pass at the project and corporate level for the

duration of construction.

 The JV Partners announced FID for construction of Phase 1 of Thacker Pass. Completion

of Phase 1 of Thacker Pass is targeted for late 2027.

 Contemporaneously with FID, GM and Lithium Americas contributed $100 million and

$192 million in cash to the JV, respectively.

Jonathan Evans, Lithium Americas’ President and CEO said, “Today marks another important

milestone in our journey to bring Thacker Pass to production. With our JV Partner, GM, we

announced FID for Phase 1 alongside our other exceptional partners – the U.S. DOE and Orion.

Together, we will develop a U.S.-produced lithium supply chain to reduce American dependence

on foreign suppliers for critical minerals.”

owned by a JV between Lithium Americas (holding a 62% interest and is the manager of the

Project) and GM (holding a 38% interest). The Company is focused on advancing Thacker Pass

Phase 1 toward production, targeting nominal design capacity of 40,000 t/y of battery-quality

lithium carbonate. The Company and its engineering, procurement and construction management

contractor, Bechtel, entered into a National Construction Agreement (Project Labor Agreement)

with North America’s Building Trades Unions for construction of Thacker Pass. The three-year

construction build is expected to create nearly 2,000 direct jobs, including 1,800 skilled

contractors. Lithium Americas’ shares are listed on the Toronto Stock Exchange and New York
