       RIO DE JANEIRO, Oct 5 (Reuters) - Sigma Lithium
 SGML.V  SGML.O  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. 
    Talbot became COO last year, overseeing operations at
Sigma's flagship Grota do Cirilo mine. His exit from Sigma, the
poster child for Brazil's budding lithium sector, comes amid a
legal battle between the husband-and-wife pair who ran the
company together until earlier this year.
    Talbot said he presented his resignation to Sigma in late
July and his last day at the company was Friday, Sept. 29. He
did not give a reason for his exit. 
    Sigma did not immediately reply to a request for comment.
    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." It also said that efforts to attract
a buyer for Sigma, which is looking for a buyout, were not
affected. 
    Gardner left his co-CEO role in January, and Sigma announced
a new chief financial officer in August.
