CIMIC Group’s contract mining company Thiess has received a contract extension valued at A$1.3bn ($893m) to provide mining services at Coronado Global Resources’ Curragh mine in Queensland, Australia.

Under the terms of the six-year contract, Thiess will continue to provide overburden removal and haulage, mining and run of mine (RoM) re-handling services, equipment maintenance and pit dewatering services at the mine.

The Curragh mine is located in the metallurgical coal-rich Bowen Basin. Thiess has been offering services at the mine since 2004.

CIMIC Group CEO Michael Wright said: “Thiess has a consistent record of exceeding our client’s expectations at the mine, through a focus on operational excellence and innovation, and an unrelenting commitment to safety culture and outcomes at Curragh.

“This contract extension reflects Thiess’ on-going ability of creating lasting value for its clients.”

Thiess will continue to deliver its existing scope of works, which include the operation and maintenance of the client-owned 1400t electric rope shovel and trucking fleet.

CIMIC Group Mining and Mineral Processing executive and Thiess managing director Douglas Thompson said: “We are delighted to be continuing our partnership with Coronado Resources . Thiess has operated at Curragh for more than 15 years.

“Over that time, we’ve developed a deep understanding of the site and its operations, helping to deliver optimal efficiency, productivity and cost performance.”

Sedgman and UGL , which are CIMIC Group business units, provide various operations and maintenance contracts at the Curragh mine site.

In March, Thiess secured a contract valued at A$1.7bn ($1.2bn) for the Debswana Diamond Company’s Jwaneng Mine Cut 9 project located in Botswana.

Last November, the company won a contract to install autonomous haulage system (AHS) technology at Fortescue Metals Group’s Christmas Creek iron ore operations in the Pilbara region of Western Australia.
