Appin Mine consists of the merged Appin and Tower (now Appin Colliery - West) Collieries.
Appin Mine underground longwall mining operations have transitioned wholly to the Appin Area 9 (AA9) and Appin Area 7 (AA7) mining domains following completion of longwall mining activities at West Cliff (Appin North Colliery) in early 2016. Mining operations in AA9 were completed in FY23.
In FY 2023, South32 invested in Illawarra Metallurgical Coal’s transition to a more efficient single longwall configuration at Appin from FY25, and additional ventilation capacity to enable mining in Appin’s Area 7 until at least 2039. |

Summary:
Illawarra Coal's assets are located in the southern portion of the Sydney Basin within the Southern Coalfield.
The full sequence of Triassic to Permian sedimentary units are present within the Illawarra Coal's areas, including the Permian Shoalhaven Group, Illawarra Coal Measures and the overlying Triassic Narrabeen Group and Hawkesbury Sandstone.
Bulli Coal is the uppermost coal unit in the Illawarra Coal Measures. It is extensively worked in the northern portions of the Southern Coalfield. The Bulli Seam is the main economic coal seam for the Bulli Seam Operation - Appin mine and West Cliff Colliery (now Appin North). It averages approximately 2.6 m thick across Appin, gaining a maximum thickness of approximately 4.1 m. The Bulli Seam thins to approximately 1.4 m in the south eastern part of West Cliff (now Appin North) and also south west of Appin. Overall, the coal thickness for the Bulli Seam is generally consistent across Bulli Seam Operation in the mined out areas and planned areas of longwall mining;
The structure over the Illawarra operation area is relatively well defined based on the geological data available. Seam dips over the area are generally low (1° to 3°).
The faults have been identified by 3D seismic, 2D seismic, underground mapping, underground drilling, de-gassing intra-seam holes and, to a lesser extent, interpreted from floor contours generated from drill-hole data. The faults are predominately extension norm ........

Summary:
Appin Mine underground longwall mining operations transitioned wholly to AA7 and AA9 following completion of longwall mining activities at Appin North (West Cliff Area 5) in early 2016. In FY23 AA9 operations were completed, and operations have transitioned wholly to AA7. Appin Mine extracts coal from the Bulli Seam within the Southern Coalfield.
Appin Mine underground longwall mining operations are accessed from three surface locations: Appin North, Appin West and Appin East.
Longwall (LW) 709 commenced on 22 February 2022 and as of the end of the reporting period had retreated approximately 2034 m with an estimated completion in September 2023.
Extraction of LW905 commenced on 25 September 2022 and was completed on 28 February 2023.
Ore and Product Stockpiles
No coal is stockpiled at Appin West, as ROM coal is transported underground to Appin East or the West Cliff Coal Preparation Plant (WCCPP). The Appin West coal storage bins are currently under care and maintenance.
Appin East has a total raw coal stockpiling capacity of up to 50,000 tonnes. The stockpile is recovered with front-end loaders and transferred directly into the coal haulage trucks for transport by road to either the WCCPP or Dendrobium Coal Preparation Plan (DCPP).
Appin North operates six primary coal stockpiles for both clean coal and raw coal.
