About Our Coal

The Giles Creek coal is a typical West Coast sub-bituminous coal with low ash, low sulphur and clean burning qualities. There are estimated reserves of 16 million tonnes of recoverable coal in the current permitted area. The extensive coal seams offer a security of supply through an established resource base with a proven, locally owned and operated company. This scope of reserves and expertise in mineral extraction ensures a security of coal supply for those customers investing in energy units which accommodate sub-bituminous coals.
