Sigma Lithium wins court ruling, resumes Grota do Cirilo operations in Minas Gerais

Brazil's TRF-6 provisionally reinstated Sigma Lithium's environmental licenses for the Grota do Cirilo project, allowing operations to resume. The ruling reverses a prior suspension, removing a key operational overhang for the company. This is a company-specific legal development with limited macro impact, though it may affect lithium supply expectations.
