Pozuelos-Pastos Grandes

Pozuelos-Pastos Grandes is a lithium brine project located in Salta province in northwestern Argentina, within the Lithium Triangle region. The project encompasses salt flats at high altitude where lithium-rich brines occur naturally beneath the surface. Pozuelos-Pastos Grandes is operated by Lithium Argentina in partnership with the provincial mining company JEMSE (Jujuy Energía y Minería Sociedad del Estado). The project aims to extract and process lithium brines to produce battery-grade lithium carbonate for use in electric vehicle batteries and energy storage applications. Salta province, along with neighbouring Jujuy, hosts several major lithium brine developments that collectively form a key part of Argentina's emerging lithium industry. The Pozuelos-Pastos Grandes project is situated in a region characterised by arid climate, high solar evaporation rates and favourable geology for brine concentration. Development of the project involves the construction of evaporation ponds, processing plants and associated infrastructure. The facility contributes to Argentina's position as one of the world's leading lithium-producing nations alongside Chile and Australia.
