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.
