Vale receives negative safety report for 3 dams, sees no impact on output

RIO DE JANEIRO/SAO PAULO - Brazilian miner Vale failed to meet safety standard levels for three dams in Minas Gerais state, the company said in a securities filing on Wednesday, adding it did not see any impact on iron ore production this year.

Three dams and three dikes have received negative stability condition declarations after regular rounds of inspections, the company said. No evacuation of personnel or nearby communities is needed, Vale said.

The structures are on level 1 of the emergency protocol, a four-level scale in which 0 is no risk and 3 is imminent risk of failure.
