A Brazilian judge ordered Sigma Mineração SA, an operating subsidiary of Sigma Lithium Corp., to deposit 50 million reais ($9.9 million) with a court in the next 10 days to ensure it covers alleged damages linked to the company’s Grota do Cirilo lithium operation.

The emergency injunction on Sunday, part of a collective lawsuit brought by state prosecutors, requires Sigma to pay for independent technical advisers chosen by affected communities, create an optional emergency resettlement program, finance public health measures and suspend noisy nighttime operations from 10 p.m. to 6 a.m.
