Brazilian Judge Suspends Sigma Lithium's Mine Licenses and Operations
A Brazilian judge has suspended mining operations and environmental licenses at Sigma Lithium’s Grota do Cirilo mine in Minas Gerais. The decision followed a lawsuit by the Federation of Quilombola Communities, which argued that the mine affects the Bau Quilombola Community—a protected traditional community of African descent. Judge Antonio Lucio Tulio de Oliveira Barbosa cited evidence placing the Bau territory within 8km of the mine’s impact zone, triggering legal requirements for consultation with affected communities. The court has ordered an independent georeferencing expert to determine precise distances and halted new license approvals by Minas Gerais state. Sigma Lithium maintains that its operations are outside required zones but faces fines if it continues without compliance. Grota do Cirilo is the company’s only active mine, with a production capacity of 330,000 tonnes per annum (tpa) and an ongoing expansion project expected to nearly double output.
