Ganfeng lithium's PPGS project advances in Argentina

The PPGS lithium salt lake project, a joint venture between Ganfeng International and Lithium Argentina AG (LAR), has received its environmental impact assessment report (DIA) from Argentina's Salta provincial mining and energy secretariat. The project aims to consolidate the PPG, PG, and Puna lithium salt lake projects under Millennial, with Ganfeng International holding 67% and LAR holding 33% equity. The PPGS project plans to apply for Argentina's large investment promotion regime (RIGI) in the first half of 2026.

According to technical reports, the consolidated PPGS project boasts approximately 15.07m tonnes of LCE in measured and indicated resources, making it one of the largest undeveloped brine lithium resources globally. The project is designed for an annual production capacity of 150,000 tonnes of LCE, to be built in three phases over a 30-year lifespan.

Golder's assessment estimates the average operating cost for an annual production of 150,000 tonnes of LCE at $5,027 per tonne, including $4,026 for mining and processing. For the first phase, producing 50,000 tonnes of LCE annually, the average operating cost is projected at $5,344 per tonne, with mining and processing accounting for $4,228. The project will utilize Ganfeng Lithium's direct lithium extraction and solar evaporation technologies.
