Pastos Grandes

Location Argentina’s Lithium Triangle in Salta Province, approximately 100 km south of Caucharí-Olaroz
Ownership 100% Lithium Argentina
Resource Lithium brine from the Pastos Grandes Salar
Stage Feasibility stage, permitted, and advancing a $30-million development plan.  
Operation Exploring opportunities to produce lithium chloride (up to 6%) from ponds with potential complementary extraction technologies and chemical processing off-site in northern Argentina
Offtake Uncommitted
Acquisition Acquired from Millennial Lithium in early 2022 to further develop the growth pipeline in Argentina. Additional mining concessions (LAC Norte and Sur) were acquired later in 2022.

April 2023: Lithium Resources Update Pastos Grandes Project

Sal de la Puna Project

Location Argentina’s Lithium Triangle in Salta Province, approximately 100 km south of Caucharí-Olaroz and less than 1 km east of the Pastos Grandes project
Ownership A joint venture between Lithium Argentina (65% interest) and Ganfeng (35%)
Resource Lithium brine from the Pastos Grandes Salar
Stage Pre-feasibility. A three-dimensional groundwater flow and transport model was initiated in 2022 to evaluate mineral reserves, and Lithium Argentina is now updating this model to consider the development of Sal de la Puna and Pastos Grandes.  
Operation Development advancing in line with Pastos Grandes
Offtake Uncommitted
Acquisition Lithium Argentina acquired Sal de la Puna in April 2023 with the all-share acquisition of Arena Minerals, for total consideration of US$227 million (including LAC’s existing 19.9% interest)

The strategic acquisitions in the Pastos Grandes Basin are complementary to our overall portfolio. Given the close proximity of the two projects, we are exploring the possibility of joint development and integration of the basin as well as the use of DLE technology, which would result in a more optimal and sustainable well field design and pumping plan. This consolidation of the Pastos Grandes Basin in a timely and cost-effective manner provides Lithium Argentina with a strong growth pipeline to complement our existing operation at Cauchari-Olaroz.
