Brazilian iron ore miner Vale (NYSE: VALE) has published the results of an independent report into the Córrego do Feijão mine’s tailings dam collapse that killed 270 people last year, which reveals the company knew about the facility’s fragile condition since 2003.
According to the document, prepared by a committee formed by Vale last year, concerns about how unstable the main B1 dam was were raised at various points over the course of 16 years, but the miner failed to appropriately deal with them.
Last month, state prosecutors charged Fabio Schvartsman, the chief executive at the time of the burst, and 15 other people with homicide. Schvartsman left his position at the company in March 2019.
They also charged Vale and its German contractor, TUV SUD, with environmental crimes, as the burst unleashed an avalanche of muddy mining waste that polluted the nearby town of Brumadinho, water streams and agricultural land.
The independent committee, led by former Federal Supreme Court minister Ellen Gracie, concluded the tailings storage facility’s rupture was triggered by structural instability caused by liquefaction.
