Owner MACH Energy had sought approval to extend the life of the operations until December 2048 and deepen part of the open cut mining area, allowing for the extraction of about 444 million tonnes of run-of-mine (ROM) coal over the life of the mine.
The project would also increase the existing approved extraction rates from 10.5 to 21mt per annum of ROM coal. |

Summary:
The Mount Pleasant Operation coal resource is located in the Permian Wittingham Coal measures of the Singleton Supergroup. Lithologies comprise mostly sandstones, siltstones and coal measures 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 (PPK Environment & Infrastructure, 1997).
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 ........
