If you thought Shenhua and Adani had raised hackles with their plans to develop new coal mines in controversial parts of Australia, you ain’t seen nothing yet.

In a move likely to enrage environmental campaigners, BHP Billiton quietly flagged on Wednesday that it would soon start production of coal at the Haju mine in Indonesian Borneo.

Haju will initially produce about 1 million tonnes of coal a year, which is pretty small compared to the coal mines BHP already operates in Queensland.
