The new offer, which is 13 billion reais higher than the previous one, marks a significant step forward in the negotiations.
The miners had initially offered a total of 127 billion reais ($25.0 billion) in December last year, while the Brazilian government and the affected states had requested 155 billion reais ($30.6 billion).
Last May, Brazil’s government filed a request before a federal court in Minas Gerais state asking that Vale, BHP and Samarco pay 79.6 billion reais ($15.7 billion) within 15 days.
The dam collapse at the Samarco iron ore mine near the town of Mariana in Brazil’s southeastern state of Minas Gerais caused a vast flow of mud and mining waste that buried a nearby village, killing 19 people and leaving hundreds homeless.
The new offer includes a cash payment of 82 billion reais ($15.3 billion) payable over 20 years to the federal government, the states of Minas Gerais and Espírito Santo, and municipalities, and 21 billion reais ($3.9 billion) in obligations to be fulfilled.
The amounts include a 50% contribution from BHP Brasil and Vale as secondary debtors in case Samarco cannot finance as the primary debtor.
