View shows Sigma Lithium Corp production at the Grota do Cirilo mine in Itinga, in Minas Gerais state, Brazil April 18, 2023. Sigma shares were down about 10% around midday in New York. Last week, Reuters reported that divorce proceedings between Sigma Chief Executive Ana Cabral-Gardner and Calvyn Gardner, her husband and former co-CEO, had triggered several lawsuits, including a dispute over some of the mineral rights where Sigma plans to build mining pits. At the time, Sigma told Reuters the dispute would not affect its expansion plans, as it said it can develop the area via a "waste sharing agreement." Gardner left his co-CEO role in January, and Sigma announced a new chief financial officer in August.

REUTERS/Washington Alves/File Photo Acquire Licensing RightsRIO DE JANEIRO, Oct 5 (Reuters) - Sigma Lithium (SGML.V) Chief Operating Officer Brian Talbot left the company at the end of last month, he told Reuters on Thursday, in the latest management shakeup at the Vancouver-based miner. Last week, Reuters reported that divorce proceedings between current Sigma Chief Executive Ana Cabral-Gardner and Calvyn Gardner, her husband and former co-CEO, had triggered several lawsuits, including a dispute over some of the mineral rights where Sigma plans to build mining pits. At the time, Sigma told Reuters the dispute would not affect its expansion plans, as it said it can develop the area via a "waste sharing agreement." Gardner left his co-CEO role in January, and Sigma announced a new chief financial officer in August.

☆ Exclusive: Brazil mineral rights dispute casts shadow on Sigma Lithium expansion

View shows Sigma Lithium Corp SGML.V production at the Grota do Cirilo mine in Itinga, in Minas Gerais state, Brazil April 18, 2023. That transaction, Gardner's lawyers argued, would grant Sigma mineral rights to valuable lithium deposits and hurt RI-X's ability to develop its own mining project. At the time of the transfer, Gardner owned 49% of RI-X and Cabral-Gardner held 51%, documents show. Sigma shares, which had been up 4% in afternoon trading on Thursday, erased gains to close more than 2% lower after Reuters reported on the court injunction. Sigma declined to comment on the New York lawsuit, and said "the divorce proceedings are a private, personal matter and have no impact on how Sigma Lithium conducts business."
