Located in central Queensland’s Bowen Basin, Cook Colliery produces hard coking, semi-soft and thermal coal products primarily for the export market. The colliery’s operating company, Cook Resource Mining Pty Ltd (CRM), is owned by Xstrata (95%) and Tokyo Boeki (5%).

In June 2006, Xstrata Coal announced the partial sale of its Cook Colliery for a cash payment of A$45.6m to Caledon Resources plc (Caledon). Caledon was granted a sub-lease to mine the Southern region and accepted responsibility for the rehabilitation of the area.

Cook Resources Mining Pty Ltd retained exclusive ownership of the Northern Region for exploration.
