Sigma Lithium reported on Friday that its chief operating officer, Brian Talbot, left the company at the end of last month, confirming a Reuters report, which sent the company’s shares tumbling on Thursday.
Talbot became COO last year, overseeing operations at the Sigma Grotta do Cerillo mine, an example of the growing potential of Brazil’s lithium sector. The former mining company CEO announced his resignation in July and his last day at the company was on September 29.
His departure marks at least the third change in Sigma’s top management in 2023, amid a legal battle between the husband and wife who ran the company together until the beginning of this year.
Sigma said Talbot resigned for health reasons.
Marcelo Paiva, co-chairman of the mining company’s board, said in a statement that the company “agreed to respect Mr. Talbot’s decision regarding the timing of his resignation announcement.”
Talbot told Reuters that Paiva’s comments were “factually incorrect.” “There was no request to hide the fact of my resignation from investors in July,” he said.
The former operations manager said he was “surprised” that Sigma revealed his personal information, adding: “My health is excellent now and I am focused on the future.”
Talbot said he now works for his own company, R-Tek.
Sigma said it has promoted mining directors Reynaldo Brandao, processing Keith Prentice and geology and regional corporate relations Eran Zhan to “associate general manager”.
The mining company added that these executives had been in charge of Sigma’s local operations in Brazil for about four months.
Last week, Reuters reported that the divorce proceedings between Sigma’s CEO, Ana Cabral Gardner, and Calvin Gardner, her husband and former co-CEO, have sparked several legal proceedings, including a dispute over some mineral rights that Sigma plans to build. Mines.
Sigma told Reuters at the time that the dispute would not affect its expansion plans, as it said it could develop the area through a “waste-sharing agreement.” It also said efforts to attract a buyer for Sigma, which is seeking a takeover, had not been affected.
Gardner left him office as co-CEO in January, and Sigma announced a new CFO in August.
