Thiess, a subsidiary of the CIMIC Group, has secured a six-year contract with MACH Energy for mining services at the Mount Pleasant Operation in New South Wales. 

This new contract award builds on Thiess’ current engagement, extending it through to the end of 2031 and includes an expanded scope of work. 

Under the new agreement, Thiess will continue to provide full mining services at the Mount Pleasant Operation, including mine planning and engineering, drilling and blasting, loading and hauling, run-of-mine rehandling, asset management and maintenance as well as progressive rehabilitation to support the mine’s expansion. 

“We are very pleased to continue our collaboration with MACH Energy, which began at the commencement of the mine. Since 2017, our high-performing team has consistently achieved production targets and delivered strong safety outcomes, driving productivity and cost-effectiveness, and upholding our commitments to the local community and sustainability. 

“Aligned with our client’s objectives, we are focused on driving further productivity gains through an expanded fleet, enhanced infrastructure and innovative technology,” Thiess Group Executive Chair and CEO Michael Wright said. 

“Thiess has been an active member of the Hunter Valley community since the Thiess Brothers first began operations in NSW in 1944. We continue to support the local economy, providing employment opportunities and delivering high-quality mining solutions for our clients. 

“This contract recognises the dedication of our largely local workforce, and reflects the region’s commitment to balancing its mining heritage and sustainable development,” Thiess Group Executive – Australia East Rae O’Brien said. 

As Mount Pleasant Operations continue to grow, Thiess will expand its services while maintaining existing operations, with a strong focus on people as well as technology and sustainable mining practices to increase production. 

The Mount Pleasant Operations is a greenfield open cut coal mine located about 2.5 kilometres from Muswellbrook in the Upper Hunter Valley region of New South Wales, with an estimated474 million tonnes of coal reserves to be mined.
