🔴 Sigma Lithium Resources is trading 12.43% down today after court halted mining at Grota do Cirilo

Sigma Lithium Resources is trading 12.43% down now at $10.85 after a Brazilian federal court suspended environmental permits and ordered mining halted at Grota do Cirilo, its sole producing operation.

• The ruling followed allegations that the project affects the nearby Baú Quilombola community and failed to meet consultation requirements.
• Sigma Lithium disputes the ruling, saying operations remain active and it had not received formal legal notice while preparing its defense on September 8, 2026.
• The court action remains the clear catalyst behind the sharp decline.
