Deposit Type

  • Sedimentary


Summary:

Coal resources associated with the Project Boundary occur within the early Permian age Maules Creek Formation of the Maules Creek Sub-basin. The Maules Creek Formation contains 15 named coal seam groups with the coal measures generally dipping towards the south-east at 1-7 degrees.

The basement of the Maules Creek Sub-basin is formed by the Boggabri Volcanics. The rhyolitic volcanics are overlain by the Leard Formation, a thin unit comprised of black claystone and rare, thin coal seams. The Maules Creek Formation is up to 800 m thick within Aston’s mining authorities and sits conformably on the Leard Formation.

Within CL 375, the Maules Creek Formation contains 15 named coal seam groups, which exhibit splitting towards the north-east. This seam splitting has resulted in the recognition of up to 39 individual seam plies resulting in complex geological modelling. The identified coal measures generally dip towards the south- east with a flattening of dip occurring in the far south-eastern corner of CL 375 (coal lease).

Dips range from 1 to 7 degrees but are within the range of comfortable open cut mining operations. Dip direction is generally consistent across the deposit.

Coal will be extracted from all 15 defined seams, via open cut methods down to the Templemore seam. All seam groups situated stratigraphically below the Braymont Seam lap onto the basement volcanics. The depth of weathering across the modelled area varies from 6 m t ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

Maules Creek Coal Mine (MCCM) is an open cut coal mine with an approved maximum ROM coal production rate of 13 Mtpa to December 2034. Pre-mining clearance activities including ecological, archaeological and soil analysis were undertaken in line with the relevant approvals and management plans.

Topsoil was reclaimed from the area to be mined and stockpiled for later use on rehabilitation areas. Overburden is blasted prior to being removed by loader and / or excavator and trucks before proceeding with coal extraction.
