Lithium Americas Provides Updates on the Cauchari-Olaroz and Thacker Pass

Projects

VANCOUVER, British Columbia, Feb. 25, 2019 -- Lithium Americas Corp. (TSX: LAC; NYSE: LAC) (“Lithium Americas”,

“LAC” or the “Company”) is pleased to provide a construction update on the Cauchari-Olaroz lithium project (" Cauchari-

Olaroz") in the Province of Jujuy, Argentina. Cauchari-Olaroz is 100%-owned by Minera Exar S.A. (“ Minera Exar ”), a joint

venture company owned 62.5% by Lithium Americas and 37.5% by Jiangxi Ganfeng Lithium Co., Ltd. (“Ganfeng Lithium ”).

Although January and February are characterized as the rainy season at Cauchari-Olaroz, the site has received unusually

heavy rainfall during recent weeks. Minera Exar is pleased to report minimum disruptions to the current construction activities

and Caucharí-Olaroz remains on track to reach production in 2020.

Jon Evans, the Company’s President and COO, commented, “Heavy rainfall in January and February has not had a material

impact to our construction activities and schedule.  We note the temporary disruptions to the international paved highway in

Jujuy were quickly corrected and the dilution impact to the ponds was minor at this stage of development.”   Mr. Evans

continued, “We are very pleased with the progress at site and continue to work closely with our partner, Ganfeng Lithium, to

explore ways to further optimize the project.”

Additional construction updates are as follows:

• Evaporation ponds: Two ponds are now completed with the first pond currently being filled with brine from the production

wells. There are another four ponds under construction. Pond construction is on schedule to complete all evaporation

ponds covering 12 km2 during the first quarter of next year. Liner supply and liner installation contracts for the remaining

ponds have been awarded securing supply for the critical material.

• Production wells: Currently there are seven wells in production and three more are under construction. By the end of

April, the project is scheduled to have seven drilling rigs mobilized at site for drilling of additional production wells.

• Civil: Work associated with roads and platforms continues as planned. Contracts have been awarded for earthworks

(plant and operations camp), concrete supply, and other key items.

• Procurement: Minera Exar is in the process of reviewing proposals for long lead items and expects to finalize such

awards in due course.

The Company is also pleased to provide an update on development of its 100% owned Thacker Pass lithium project (“Thacker

Pass”) located in Nevada.  Following the release of the Preliminary Feasibility Study in August 2018, through development of a

pilot plant in Reno, Nevada, the Company is considering the production of lithium hydroxide directly from lithium sulphate to

provide added flexibility. Commissioning of the pilot plant is underway, with testing and optimization expected to commence in

the near term.

The Company continues to advance engineering work and mine plan design. The Company has also completed environmental

baseline data collection and is advancing its permitting applications.
