An Australian inquiry into a blast that seriously injured five workers found that the miner repeatedly produced more methane gas than it could remove and had exposed workers to excessive risk.

Vale was obliged to halt the mine after the workers rejected its initial offer.

The company has a growth initiative in place at each of its core copper operations comprising four operating mines.

Mine in Northern Labrador has started the production at its Reid Brook deposit.

The gold miner also expects to release an updated feasibility study for Wasamac by late July.

Vale is considering the use of remote-controlled trains near the Xingu dam for the flow of its production.

It would take around 60 days for Vale to implement the solution, according to a person familiar with the plan.

A split would be just one way for Centerra to resolve issues with Kyrgyzstan’s government, which also owns 26% of the company.
