Formerly owned by Wesfarmers Resources, the Curragh Coal Mine (now operated by Coronado Curragh Pty Ltd) is located in Queensland’s Bowen Basin, 30km north of Blackwater. The main product from the mine is metallurgical (coking) coal for export.

Wesfarmers identified a need to refurbish the run of mine (ROM) coal handling facility at Curragh, in order to accommodate increased production and potential future expansion requirements. They subsequently embarked upon a major upgrade of this essential infrastructure, to enable increased reliability and capacity, and extend the life of the facility.
