Brazilian miner Vale has raised the emergency level at the Sul Inferior dam at its Gongo Soco mine in Barão de Cocais, in the southern state of Minas Gerais, after heavy rainfall eroded the structure’s reservoir.
"As a result of unusually heavy rain, Vale reinforced the number of field teams on standby for any eventual emergencies," Vale said in a securities filing late on Saturday, adding that the dam was raised to ‘Level 2’ watch from ‘Level 1’.
