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 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.
Mud and wastewater from burst dams at a Brazilian iron ore mine cut off drinking water and raised health and environmental concerns in cities more than 300 km downstream on Monday, amid increasingly dire search efforts in a village devastated by the mudslides.
Brazilian authorities are still struggling to determine what caused the rupture in dams at an iron ore mine and desperately working to recover the bodies of as many as 28 people believed to have been swept away in the massive mudflow and flood.
