Sigma Lithium was awarded its environmental operating license (LO) to operate its wholly owned Grota do Cirilo project, the largest hard-rock lithium project in the Americas, and to produce Battery Grade Sustainable Lithium Concentrate (Green Lithium)

The LO enables the company to sell all Green Lithium product from current and future production, including any stockpiled product. After a successful SUPPRI inspection in February 2023, LO certificate number 4078 was issued, thus concluding the licensing process and approving Sigma Lithium to commence commercial operations at its Phase 1 Mine and Greentech Plant.

The company is also pleased to report that commissioning of the Phase 1 dense medium separation (DMS) circuit of its Greentech Plant remains on schedule with initial production expected to commence in April 2023. This follows the successful completion of crushing circuit commissioning of the Greentech Plant as announced on February 13, 2023.

Sigma Lithium has appointed DRA Global Limited (DRA) to work alongside Promon Engenharia Ltda. (Promon) on the design and construction of the Phase 2 & 3 expansion of the Greentech Plant, which is expected to be fully funded internally through cash flow generation.
