The Pozuelos-Pastos Grandes project, also known as PPG, represents the union of the Pastos Grandes and Pozuelos projects. It encompasses the Salar de Pastos Grandes and Salar de Pozuelos basins, 13 km south-southwest of the city of Santa Rosa de los Pastos Grandes, 56 km southwest of the city of San Antonio de los Cobres, and 154 km northwest of the provincial capital city of Salta. At 3,785 masl, it spreads across over 8,664 hectares of the Salar de Pastos Grandes.
The idea is to employ proven technology for processing, such as brine extraction, solar evaporation and conventional lithium brine processing. The useful life of Pastos Grandes is 25 years, with a start-up period of three years and expected output levels of up to 25,000 tons per year. Pastos Grandes is expected to start producing in 2024. Lithea Inc., a subsidiary of Ganfeng Lithium in Argentina, has been working on the project since the end of 2022, after it was acquired from Lítica Resources.
The project has its own crew camp and the plan is to expand both capacity and operational facilities.
