Located in Central Queensland’s Bowen Basin, Caval Ridge is the largest greenfield metallurgical coal-mining complex in Australia. The complex produces hard export metallurgical coal for use as coke in steel mills in China, India, and elsewhere.
Owned by the BHP Billiton Mitsubishi Alliance (BMA), the mine's initial production capacity was expected to be 5.5 million metric tons per year.
Bechtel partnered with the joint venture on the design and construction of its project, including a metallurgical coal mine, a handling and preparation plant, and other facilities.
Metallurgical coal from Caval Ridge, and the joint venture's other properties (including Daunia), is exported via the Hay Point terminal. Bechtel collaborated with the BMA to build Daunia and expand Hay Point, the latter of which is roughly 150 miles (about 240 kilometers) northeast of Caval Ridge, just south of Mackay.
