The Mariana project is located in the Salar de Llullaillaco, in the province of Salta (Argentina), some 430 km from the provincial capital. From Salta City, it takes some 8-10 hours to reach the site, which lies 95 km from the nearest town, Tolar Grande, at 3,750 masl. Litio Minera Argentina S.A., a Ganfeng subsidiary in Argentina, is leading the project.
With an investment of around six hundred million dollars (USD 600,000,000), Ganfeng Lithium owns 100% of the share capital. It is estimated that over 1,300 direct and indirect jobs will be created during the construction phase.
In June 2021, the Mining Secretariat of the province of Salta approved the Environmental Impact Study. Solar energy will be used to power the plant in the salt flats, ensuring the project is fueled by renewable energy.
