CIMIC Group’s global mining services provider, Thiess, has been awarded a contract extension by BHP Mitsubishi Alliance (BMA) to provide mining services at the Caval Ridge coal mine in Queensland, Australia.

The 12-month contract extension will generate revenue of A$110 million ($79 million) to Thiess, CIMIC said.

Under the contract variation, Thiess will continue to operate and maintain three 600 t excavator fleets to move additional overburden for the Caval Ridge operation, an open-pit coal mine with a 10 Mt/y throughput capacity.

Back in 2018, Thiess and BMA signed a contract variation that saw the contract miner move additional overburden through 2020 as per the terms of the contract.

CIMIC Group Chief Executive Officer, 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.”

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.”

The contract extension will commence in December 2020.

Last week, CIMIC confirmed that it was close to bringing in a new equity investor for its Thiess contract mining business.
