CIMIC Group’s contract mining company Thiess has secured a contract extension to provide mining services at BHP Mitsubishi Alliance’s (BMA) Caval Ridge coal operation in Queensland.

BMA is a 50:50 partnership between Anglo-Australian BHP Group and Japan’s Mitsubishi Corporation.

The Caval Ridge coal project is located at Bowen Basin, Central Queensland. It is a high-quality, hard coking coal mine situated in the northern section of the Bowen Basin.

Under the one-year contract extension, CIMIC Group subsidiary is expected to generate revenue of A$110m ($78.9m).

CIMIC Group CEO Juan Santamaria said: “This contract extension builds on our relationship with BMA and reinforces our commitment to work with our clients to safely position their operations for optimal efficiency, productivity and cost performance.”

The contract will see Thiess operate and maintain three 600-tonne excavator fleets.

Thiess noted that the fleets will move additional overburden for the coal operation.

CIMIC Group Executive Mining and Mineral Processing and Thiess managing director Douglas Thompson said: “We’re proud to continue our work at Caval Ridge where we have a proven track record of delivering innovative and low-cost mining solutions.

“It is a testament to the team’s continued focus on delivering a safe and productive operation for our client.”

Last month, Thiess secured a contract from commodities trader and miner Glencore to provide mining services at the Mount Owen coal mine in Australia.
