Brazilian iron ore miner Vale SA told prosecutors in the state of Minas Gerais that a dam is at risk of rupturing at its Gongo Soco mine, about 40 miles from where its Brumadinho dam collapsed, killing more than 230 people.
According to a document published on Thursday, prosecutors said Vale is predicting the dam in the city of Barao de Cocais may collapse next week if the current rate of movement in the embankment of the mine pit close to the dam is maintained.
