Lithium Americas Corp. Defines the 3rd Largest Lithium Brine Resource in the World

Company Files Updated NI 43-101 Resource Estimate and Is Well Positioned to Advance Project to Feasibility

Targets 2012 for Mine Construction

TORONTO, ONTARIO--(Marketwire - Dec. 6, 2010) - Lithium Americas Corp. (TSX:LAC) ("Lithium Americas" or the "Company"), today announced that it has filed its updated resource estimate of its Cauchari-Olaroz lithium–potassium property in Argentina with the Canadian regulatory authorities. As announced on November 8th, the Company's resource increased by more than 60 percent from the previous estimate and the average lithium grades increased by up to 13 percent. The NI 43-101 compliant resource estimate and technical report was completed under the supervision of Dr. Mark King (Groundwater Insight Inc., Nova Scotia, Canada), as an independent Qualified Person. The report is available online in both the SEDAR Database ( and Lithium Americas' website. According to available industry data and to the best of Lithium Americas' knowledge, the in situ resource estimated to be contained in the Company's Cauchari-Olaroz project is now the third largest lithium brine deposit in the world, trailing only the Uyuni deposit in Bolivia, and the Atacama deposit in Chile, which is currently the largest producing brine resource.

The validation of the size and quality of the resource represents another significant milestone achieved by Lithium Americas since the Company began to define the Cauchari-Olaroz properties in mid-2009, and puts the Company on track to complete its Preliminary Economic Assessment ("PEA") in the first quarter of 2011. In addition to the PEA, the Company expects to complete a two-well production drilling program by December 2010, followed by the completion of a third pumping test well once pumping dynamics from the two-well program have been ascertained. The Company has successfully completed the construction of an on-site lab and pilot-scale evaporation ponds, which are currently producing lithium carbonate at laboratory scale. Large scale pilot ponds in the salar are also under construction and will be used to simulate the lithium/potassium brine evaporation process, further defining the path to commercial production.

"Our goal is to achieve large scale commercial production in the shortest, most efficient time frame possible," stated Dr. Waldo Perez, Ph.D., P. Geo., President and CEO of Lithium Americas Corp. "We have invested significant capital in programs designed to maximize our knowledge of the Cauchari-Olaroz resource. Our level of understanding of the geological and hydrological characteristics and productive potential of this resource can only be compared to the large scale lithium carbonate producers in the area. Given the momentum of our development to date, and the recognition from independent industry sources indicating that Cauchari-Olaroz is the top lithium brine project in the region, we remain confident that, subject to final feasibility, Lithium Americas will achieve its goal of initiating mine construction in 2012."

The Cauchari-Olaroz resource was estimated using accepted industry-standard methods that conform to National Instrument 43-101. Results were estimated with a block model developed using ordinary kriging techniques.

This press release uses the terms 'measured resources', 'indicated resources' and 'inferred resources' which are terms recognized and required by Canadian regulations (under National Instrument 43-101 Standards of Disclosure for Mineral Projects). Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will be converted into reserves. In addition, inferred resources have a great amount of uncertainty as to their existence, and great uncertainty as to their economic feasibility. It cannot be assumed that all or any part of the mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or prefeasibility studies, except in rare cases. Investors are cautioned not to assume that part, or all of an inferred resource can be upgraded to an indicated or measured resource or is economically mineable.
