LAC Lithium Americas Corporation

Lithium Americas Corp. (TSX: LAC) (NYSE: LAC) (“Lithium Americas” or the “Company”) is pleased to report that the Caucharí-Olaroz project (“Caucharí-Olaroz” or the “Project”) in Jujuy, Argentina has produced its first lower than battery-quality lithium carbonate as part of commissioning. Additional purification processing equipment necessary to achieve battery-quality lithium carbonate is expected to be completed in the second half of 2023, as planned.

“The initial production achieved as part of commissioning is an exciting step as Caucharí-Olaroz continues to advance toward first production of battery-quality lithium carbonate,” said Jonathan Evans, Lithium Americas’ President and CEO. “Our dedicated and skilled teams continue to work diligently to progress this transformative project.”

More information on anticipated production will be provided later this quarter. During the ramp-up stage to production capacity of 40,000 tonnes per annum, the Company expects Caucharí-Olaroz to operate substantially below designed capacity and to produce lithium carbonate below battery-quality specifications.
