A global inquiry into how mining companies store billions of tonnes of waste in huge dams, launched after a collapse in Brazil killed hundreds, shows about a tenth of the structures have had stability issues, investors said on Thursday. The research was led by the Church of England (CoE) and fund managers after the collapse of a Vale dam in January unleashed an avalanche of mining waste on the Brazilian town of Brumadinho, killing an estimated 300 people. The investor review, which found at least 166 dams have had stability issues in the past, relied on companies’ disclosures about their dams holding mining waste, known as tailings.
