Thiess says its mining services contract with BHP Mitsubishi Alliance (BMA) for the Caval Ridge operations in Queensland, Australia, has been extended for potentially another five years.

The contract, which starts on December 1, 2022, for a potential term of up to five years, has revenue to Thiess valued up to A$600 million ($389 million), it said.

Under this contract, Thiess will continue to provide mining services at the Caval Ridge mine, operating and maintaining mining equipment to move overburden to support BMA’s production requirements.

Thiess Executive Chair and CEO, Michael Wright, said: “Thiess has been providing mining solutions to BMA at Caval Ridge since December 2017. Importantly, our team continues to have a clear commitment and focus on fostering diversity and respectful workplaces, with almost 30% of the workforce being female and 10% being Indigenous.

“We continue to seek opportunities to bring under-represented groups into the mining industry, and delivering sustainable mining solutions for our clients and stakeholders.”

Thiess Executive General Manager Australia East, Cluny Randell, said: “We’re very proud to build on our safe and strong performance at Caval Ridge, and extend our deep working relationship with BMA. We will continue to drive long-term economic value by creating local jobs and regional supply opportunities, and supporting the communities where we operate.”

Caval Ridge is one of nine metallurgical coal mines in Queensland’s Bowen Basin. It is a part of BMA, the 50:50 joint venture between BHP and Mitsubishi Development.
