An in-depth internal report examining the causes of Vale SA’s deadly Brumadinho tailings dam disaster last year contained "no new facts, nor surprises," the company’s general counsel said on Friday.
Late on Thursday, Vale released the report, which said the company had information as far back as 2003 pointing to the fragility of the B1 dam in Minas Gerais, which burst in January 2019 and killed at least 270 people.
But steps taken to deal with the problem and heighten the dam’s security were limited and ineffective, according to the report by a committee led by former Brazilian Supreme Court Justice Ellen Gracie.
