Vale dam disasters trigger $2bn in fresh writedowns

Brazilian miner Vale on Wednesday said it swung to a quarterly loss as the company announced more than $2-billion in fresh writedowns related to two deadly dam bursts suffered by the company over a period of less than four years.

In late January, the collapse of a Vale tailings dam storing muddy mining waste near the town of Brumadinho killed nearly 250 people, less than four years after a deadly disaster at the company’s Samarco joint venture with BHP Group.
