RIO DE JANEIRO, May 11 (Reuters) - Brazilian labor inspectors have fined Sigma Lithium SGML.V for depositing waste in a pile that they had shut down because it posed a "grave and imminent" risk to workers and the local community, the inspectors told Reuters in a statement.

Three of Sigma's waste piles had been shut down last December, but during a Thursday visit to a town near Sigma's work site in Minas Gerais state, inspectors found that trucks were still depositing waste on to one of them.

Sigma did not immediately reply to a request for comment.
