(Reuters) - Mining heavyweight BHP <BHP.AX> said on Thursday the federal court of Minas Gerais approved an agreement with Brazilian authorities that settled a 20 billion reais (£4.12 billion) lawsuit over the 2015 Samarco dam failure.
The company said it had separately agreed to pay $50 million as part of a settlement for a class action complaint filed by American depositary receipt holders over the disaster.
Samarco <SAMNE.UL> and parent companies Vale SA <VALE5.SA> and BHP had signed a deal with Brazilian authorities in June regarding the 2015 dam failure.
Brazil's worst environmental catastrophe killed 19 people. It happened when a dam designed to hold back mine waste burst, leaving a trail of destruction for hundreds of kilometres.
BHP still faces a class action in Australia over the dam failure.
Samarco said on Wednesday it expects to obtain all licenses needed to resume operations by next year.
