Thiess has secured a $150 million contract extension at BHP Billiton Mitsubishi Alliance’s (BMA) Caval Ridge coal mine in the Bowen Basin, Queensland.
The CIMIC Group mining services business will mine additional overburden through until 2020 with the updated agreement.
Thiess will also continue to provide mining services for specific components of work, including the activities required for the Caval Ridge Southern Circuit.
The mining services company announced its original contract at Caval Ridge in October last year.
Thiess managing director Douglas Thompson said the contract extension was “a testament to the team’s track record of performance and focus on delivering a safe and productive operation”.
BMA approved a $US204 million investment in the Caval Ridge Southern Circuit in April 2017.
The Southern Circuit is an 11 kilometres overland conveyor system that transports coal from the Peak Downs mine to the coal handling preparation plant near the Caval Ridge mine.
CIMIC chief executive officer Michael Wright, commenting on the contract extension, said, “This award builds on our relationship with BMA and reinforces Thiess’ commitment to delivering value for our clients.”
