The Mount Pleasant Operation comprises an operating open cut coal mine and associated coal processing.
On 6 September 2022, the Independent Planning Commission NSW approved the Mount Pleasant Optimisation Project. The Project’s approval will extend the mine life from 2026 to 2048 and increase mining activity at the Mount Pleasant Operation. |

Summary:
The Mount Pleasant Project is located within the Hunter Coalfield, in the northern section of the Sydney Basin.
The Mount Pleasant Project coal resource is located in the Permian Wittingham Coal Measures within the Denman Formation and Jerrys Plains Subgroup and the Archerfield Sandstone and Vane Subgroup.
Lithologies comprise mostly sandstones, siltstones and coal seams with minor conglomerates and tuffs. Coal seams amenable to open cut mining occur in eight correlated seams and include the Upper Piercefield (Warkworth) Seam to the lowermost Edderton Seam.
The target coal seams vary widely across the extent of the mine, with mineable units generally ranging from approximately 0.6 metres (m) to approximately 10 m in thickness.
Summary:
The open cuts at the Mount Pleasant Operation comprise four named open cuts (South Pit, North Pit, Warkworth South Pit and Piercefield Pit2).
Development Consent DA 92/97 (as modified) allows for the extraction of 197 Mt of ROM at a rate of up to 10.5 Mtpa and allows for mining operations to be carried out until 22 December 2026.
Mining related activities have commenced and have included:
- development of the South Pit at its south-eastern extent;
- continued construction of haul road; and
- commencement of rehabilitation of the Eastern Out of Pit Overburden Emplacement adjacent to the South Pit.
Development of the South Pit at the south-eastern extent of ML 1645 will progress to the north and west during the MOP (Mining Operations Plan ). The initial portion of the Overburden Emplacement has been constructed between the boxcuts and the eastern boundary of the lease, within the footprint approved by the Development Consent. The Overburden Emplacement is a short haul from the open cut, and will develop into a bund that assists to control the potential environmental impacts of the operation. Mining will continue to progress northwards before developing to the west throughout the remaining mine life (outside of this MOP/RMP term), in accordance with Development Consent DA 92/97.
Mining Operations
Mining at the MPO has commenced in the south-east of the deposit and will gradually develop north and west over the m ........
