Produces lithium concentrate from the wholly owned Grota do Cirilo mining and industrial-beneficiation operation in Minas Gerais, Brazil. Commercial operations use a stated processing model built around renewable electricity, dry stacking, water treatment, and no hazardous chemicals.
Operates the wholly owned Grota do Cirilo hard-rock lithium mining and industrial-beneficiation complex in Minas Gerais, Brazil. It produces lithium concentrate after a development, construction, commissioning, and production sequence that reached commercial operations.
The operating model combines mining with industrial beneficiation. It uses renewable electricity, dry stacking, treatment of water used in industrial operations rather than potable water, and avoids hazardous chemicals, according to the company. Further construction continues at the site.
Commercial sales of current and future production were enabled by an environmental operating license. The business is concentrated in one Brazilian asset, and the ability to sell production is tied to that license.
