Lithium Americas Corp. (TSX:LAC) ("LAC" or the "Company") is pleased to announce that it is now in discussions with POSCO regarding the proposed commercialization of the Company's Cauchari-Olaroz lithium project in Jujuy Province, Argentina. The two parties expect to execute a Heads of Agreement ("HOA") shortly that will define the basic conditions governing a new Joint Venture Company ("JVC"). While the full terms of the parties' joint venture arrangements are still to be negotiated, POSCO is expected to contribute to the JVC the right to use its proprietary lithium extraction technologies for the production of lithium carbonate and lithium hydroxide, while LAC would contribute the right to use brine from its Cauchari-Olaroz salar properties.

POSCO's and LAC's decision to pursue a commercialization agreement is based on the successful results and collaborative efforts surrounding the operation of POSCO's innovative high efficiency lithium extraction demonstration plant (the "Demo Plant"). The Demo Plant, with an operating capacity of 200 tonnes per year of lithium carbonate equivalent ("LCE"), was inaugurated at the LAC Cauchari project site on December 19, 2014 and achieved full and continuous operating rates throughout a test period that ended in late January, 2015. During this period, over 20 tonnes of lithium phosphate was produced and subsequently exported to POSCO's facility in Pohang, Korea where it was further processed into battery grade lithium carbonate and lithium hydroxide. POSCO advised Lithium Americas that initial test results indicated that the Demo Plant achieved or exceeded all performance targets and that the lithium products processed in Pohang were of very high quality.

The lithium project team leader, Dr. Uong Chon, a Senior VP of POSCO, was recently quoted in the Korean business press as saying "the traditional process using the evaporation method required up to 18 months for lithium extraction and yielded low recovery rates, but our new extraction technology only requires 8 hours and has recovery rates of 90%."

POSCO and LAC contemplate that the proposed commercial plant will be capable of producing up to 20,000 tonnes per annum of LCE in an initial Phase 1 with plant construction scheduled to commence in late 2015. Additional details will be released upon the execution of the HOA. LAC's President and CEO, John Kanellitsas, commented: "Over the past year working closely with the POSCO team, we have witnessed first-hand the commitment and creativity of the POSCO scientists, engineers and technicians to perfect this industry transformative processing technology. Our proposed JVC will have aggressive and ambitious market share goals that will potentially make Jujuy, Argentina the world's future capital of lithium production. We are very pleased and honoured to continue to collaborate with Dr. Chon and his team to commercialize the innovative POSCO process into a profitable business."
