Indonesia coal miner Bumi posts record profit, sees 10pc output rise

Bumi booked a net profit of $373.3 million in 2017, a 451 percent jump from the previous year, said Bumi director Dileep Srivastava.

He cited favorable coal prices and sharp control over costs as reasons for the jump and that they helped offset the impact of lower prodution volumes in 2017.

Bumi expects coal prices to increase by 5 percent this year over last year's level of $58 per tonne, Srivastava said.
