The Mariana project will be exclusively supplied by power provided by an off-grid solar farm, producing 120 MW from solar panels with 288 MWp of battery storage. The plan is to expand capacity to 150 MW in solar panels, and 360 MWp in battery storage, exclusively manufactured by Ganfeng.
The system is designed to respect and comply with international standards in quality, energy-saving and environmental care, and has the capacity to supply both the company’s various operational facilities and the crew camp set up for approximately 500 people.

In 2022, work began to build industrial facilities to complete the lithium chloride production process, in the town of General Güemes, located in the center of the province of Salta, in Argentina. As part of this project, the company is building its own railway station to transport brine from the site in the Llullaillaco salt flats to the industrial plant.
Concentrated brine from the Mariana project will be transported to Güemes using tank-containers as part of an initiative to give the whole process greater flexibility. The design of the Güemes facilities envisages zero liquid effluents, as well as the reuse of all currents to prepare the reagents.

Litio Minera Argentina S.A. is a privately owned Argentinean company created in 2009 as a subsidiary of Ganfeng Lithium Group Co., Ltd. In the province of Salta, it is in charge of the Mariana Project concession, located in the northwest corner of the department of Los Andes, specifically on the Salar de Llullaillaco.
