The project, which is located in the Upper Hunter Valley coal corridor, has the potential to become a major underground coking coal mine producing up to 8Mtpa of run-of-mine coal for more than 20 years.

The target seams are likely to produce soft coking coal, semi-soft coking coal, PCI and export thermal coal.

The Environmental Assessment Requirements for the project have been issued by the NSW Department of Planning & Environment.

The Environmental Impact Statement and Development Application for the project are being prepared.

Mining Lease Applications for the underground mining area have been submitted, the company said.
