Brazil mining regulator halts part of Sigma Lithium's Grota do Cirilo mine over 'imminent risk'
Valor Econômico·BR·2 days ago
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.
