The Brazilian government expects to reach an agreement by Friday with Samarco Mineração to settle a 20 billion-real (US$4.9 billion) lawsuit for damages in the deadly dam disaster which burst in inland Minas Gerais creating a tsunami of mud and waste that killed 17 people and reached the Atlantic ocean.
A Brazilian federal court has ordered BHP Billiton and Vale to set aside US$ 491.5 million, with the possibility of billions more, has frozen the mining giants' assets in the country, and ordered it to carry out extensive environmental and social work in the region hit by a dam burst at its joint venture.
Brazil's deadly mining disaster could cost Vale SA at least US$443 million, but it is too early to put a price tag on what it expects to be a long clean-up from the pollution spilled when the toxic dam burst.
Australian mining giant BHP says mud spilled by the devastating collapse of a dam at a Brazilian mine is not toxic. On Thursday the UN said the dam burst at the Samarco mine unleashed a flood equivalent to 20,000 Olympic swimming pools of toxic mud.
A BHP Billiton and Vale joint venture in Brazil is facing its first civil lawsuit over the dam collapse at its iron ore mine on November 5 that buried a town and contaminated the region's main river.
Brazilian President Dilma Rousseff has slapped preliminary fines worth 250 million Reais ($94 million) against a BHP Billiton-Value owned mine in Minas Gerais state where two dams burst, killing at least seven people.
