BHP Billiton Mitsubishi Alliance (BMA) said in a statement that “Our Queensland Coal operations achieved a significant milestone … with first production achieved at the Daunia mine, ahead of schedule. The continued ramp up of this mine and the future commissioning of Caval Ridge will underpin an expected increase in the capacity of our Queensland Coal business to 66 million mtpy by the end of the 2014 year.” The two mines are estimated to cost A$5.8 billion, on top of the A$3.4 billion it is spending to expand its Broadmeadow mine and Hay Point Coal Terminal.
