SnapshotThe Ashton longwall mine produces a semi-soft coking coal. Ashton Coal Project includes the decommissioned North-east Open Cut, an underground coal mine, a Coal Handling and Preparation Plant (CHPP), and a rail siding.

Production resumed at Ashton in January 2024 after the water inflow in late June 2023 was fully addressed.

On September 25, 2024, the Federal Government has approved the mine life extension of three New South Wales coal mines, allowing them to continue operations for decades to come. Three NSW coal mines extended to 2050.

One of the mines affected by the decision is Ashton Coal Operations’ Ravensworth underground mine.

Summary:

The project area is located within the Hunter Coalfields of the Sydney Basin and includes coal resources and reserves that occur within the Foybrook Formation. This formation is part of the Vane Subgroup of the Whittingham Coal Measures and is the basal coal bearing sequence of the Singleton Supergroup.

The surface geology of the Ashton coal leases is dominated by outcrops of the Jerry’s Plains and Vane Subgroups which form the Whittingham Coal Measures. The main rock types of this subgroup include sandstone, siltstone and conglomerate, which occur with subordinate coal and tuffaceous claystone.

The Ashton area is located on the Camberwell Anticline which has a north north-west to north-west orientation and plunges to the north-west. The Camberwell Anticline is asymmetric with a moderately dipping (9° to 18° degrees) eastern limb which is situated in ML1529 and a gently dipping (6° to 9°) western limb which is situated in the remainder of the area. The western limb at Ashton contains the seams that are equivalent to those in the Auckland area at HVO. The Ashton area contains all coal seams from the Bayswater Seam to the Hebden seam which in stratigraphic descending order are:
- Bayswater;
- Lemington;
- Pikes Gully;
- Arties;
- Liddell;
- Barrett; and,
- Hebden.

The coal seams at Ashton exhibit the same degree of seam splitting, seam thickness. The Barrett Seam outcrops on the Camberwell Anticline. The stratigraphically higher coal seams above the Barrett Seam crop out sequentially from east to west throughout the Ashton area.
