Approximately 100 km along a highway from Caucharí-Olaroz
Total Measured and Indicated Resource of 4.12 million tonnes LCE
The Pastos Grandes project covers over 12,619 hectares
Feasibility Study completed by Millennial Lithium in 2019 for 24,000 tpa LCE
Located in Salta, Argentina, the Pastos Grandes lithium project currently covers over 12,619 hectares of the Salar de Pastos Grandes. Prior to being acquired by Lithium Americas in December 2021, previous owner Millennial Lithium invested over C$40 million to explore and develop the project, leading to a Feasibility Study in 2019.
Exploration and development work included 22 exploration/monitoring wells, 4 pumping test production wells, pilot ponds, a pilot plant as well as a year-round camp supported by a hybrid solar power system.
An Environmental Impact Assessment-Exploitation for construction and operation of a 24,000 tonne per year battery-quality lithium carbonate production facility was approved in June 2020, and a Declaracion de Impacto Ambiental (DIA) from the Environmental and Mining Authority in Salta Province, Argentina was issued.
