Under the extension, Thiess will continue to provide overburden removal and haulage, mining and run of mine rehandling services, equipment maintenance and pit dewatering.
Located in the metallurgical coal-rich Bowen Basin, Thiess has a long record of service at the Curragh mine, having operated at the project since 2004.
Michael Wright, CEO of Thiess parent company CIMIC Group, 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' ongoing ability of creating lasting value for its clients."
Douglas Thompson, executive, mining and mineral processing at CIMIC Group and managing director of Thiess, commented: "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. We look forward to continuing this strong record of delivery with the Curragh team."
In addition to this contract, Thiess will continue delivery of its existing scope of works, including the operation and maintenance of the client-owned 1,400t electric rope shovel and ultra-class trucking fleet.
CIMIC Group companies Sedgman and UGL also provide various operations and maintenance contracts at the Curragh mine.
