Sigma Lithium Resources is trading 7.83% down in pre-market at $11.42 after a Brazilian federal court suspended environmental permits and ordered mining to halt at Grota do Cirilo, its sole producing operation.
- Reuters and Bloomberg reported the ruling, which followed allegations involving impacts on a nearby Quilombola community.
- The company disputes the decision, says operations remain active, and plans to begin its legal defense on September 8.
