Sigma Lithium (NASDAQ: SGML) has begun negotiating a Terms for Adjustment of Procedures (TAC) Agreement with the Minas Gerais State Government after the regional environmental body SUPRAM Jequitinhonha issued fines totaling approximately US$540,000 for environmental issues dating from 2013 to 2022. The company states it denies wrongdoing, including claims of misrepresentation of environmental information since 2018, alleged pre-2023 commercial sales, and alleged impacts on two houses outside its licensed area.
