Sigma Lithium Resumes Operations Following Brazilian Federal Court Ruling

Sigma Lithium Corporation (NASDAQ:SGML) resumed its mining-industrial operations after Senior Federal Judge Mônica Sifuentes of Brazil’s Federal Court of Appeals granted an emergency motion reinstating the company’s environmental licenses. The landmark decision overturned a local federal court ruling, enabling the company to reaffirm its production guidance of 330,000 tonnes of lithium oxide concentrate annually by year-end 2027. Sigma Lithium operates as one of the largest industrial-mineral producers of lithium oxide concentrate.

Judge Sifuentes stated that a prolonged stoppage would inflict significant, lasting negative economic harm on Vale do Jequitinhonha, one of the less economically advantaged regions in Minas Gerais. Sigma Lithium noted that its existing Mine 1 South Pit operations and Cleantech Industrial Plant capacity support the 2027 target without needing added infrastructure. Following technological upgrades completed in early 2025, including a fines reprocessing circuit, the plant demonstrated daily output exceeding 950 tonnes, with several operational days surpassing 1,000 tonnes.
