Sigma Lithium Corporation (NASDAQ: SGML, TSXV: SGML) has resumed full operations at its Brazilian lithium project following a settlement with the State of Minas Gerais.
The company signed a Terms for Adjustment of Procedures (TAC) agreement, which resolves environmental disputes dating from 2013 to 2022. Under the accord, Sigma Lithium will pay up to $540,000 toward outstanding fines and allocate approximately $1 million for procedural adjustments. The company denied any wrongdoing while agreeing to widen and gravel access roads near two houses outside its licensed area.
Operations continued without disruption during a partial suspension, with sales of high-purity lithium fines—derived from reprocessed tailings and intermediate-grade products—remaining unaffected. Sigma Lithium has not commercially sold lithium materials prior to May 2023 and asserts it has not misrepresented information filed with environmental authorities since 2018.
The company now targets annual production of 240,000 tonnes of lithium oxide concentrate within 12 months, scaling to 330,000 tonnes by fiscal year 2027. Fleet upgrades are underway in collaboration with SANY, including the deployment of 75-tonne trucks and 98-tonne excavators to enhance haulage capacity.
The agreement provides legal certainty for Sigma Lithium’s operations in Minas Gerais, a key lithium-producing region in Brazil.
