In accordance with PA 08_0203, mining operations are permissible until 31 December 2021. Mining operations including rehabilitation activities at the DCM are expected to continue during this period. ROM coal production at the DCM ceased in October 2018. Approximately 300kt of ROM coal is remaining in the Weismantel pit and this remaining coal is intended to be extracted between 2020 to 2021. The MOP includes the production schedule for the next two years. |

Duralie Coal Pty Ltd (DCPL), a wholly owned subsidiary of Yancoal Australia Limited (YAL), is the owner and operator of the DCM.
Summary:
The coal resource at the DCM is located within the Permian aged Gloucester Basin in NSW. The DCM is located in the southern closure of the main synclinal structure of the Gloucester Basin and is associated with the coal bearing strata of the Dewrang Group. The Dewrang Group comprises three main stratigraphic units, namely: Mammy Johnsons Formation; Weismantels Formation; and Duralie Road Formation.
The coal seams mined at the DCM include:
• the Weismantel Seams;
• the Clareval Seams; and
• the Cheerup Seams.
The underlying basement rocks are principally volcanics of Early Permian (i.e. Alum Mountain Volcanics) and Carboniferous age that were folded during formation of the Gloucester Basin. The Early Permian and Carboniferous volcanic rocks are typically erosion resistant and form the more prominent ridges to the east and west of the DCM.
Summary:
Duralie Coal Mine consists of an open-cut, truck and excavator mine producing run of mine (ROM) coal, which is railed to the Stratford Mining Complex (SMC) and processed at the SMC Coal Handling and Processing Plant (CHPP).
No mining activities were conducted in the 2019/2020 reporting period. Mining in the Clareval pit was completed during September 2017. Mining of ROM coal within the Weismantel pit ceased in October 2018. Clearing in advance of mining has now been completed up to the approved disturbance limit in both Weismantel and Clareval. Approximately 400kt of ROM coal is remaining in the Weismantel pit and is intended to be extracted between 2020 to 2021.
During the reporting period DCPL complied with the approved operating hours. Mining operations are permitted 7 days per week, however no mining was undertaken during 2019/20. During the reporting period PAF rehandle and rehabilitation works were undertaken on day shift during Monday to Friday with no weekend work. Rehabilitation activities occurred during Q4 2019 and Q1 2020. PAF rehandle operations occurred during May and June 2020.

Summary:
COAL HANDLING AND BENEFICATION.
ROM coal is initially handled at the Duralie Coal Handling Plant (CHP). Rock greater than 140 mm is removed from ROM coal using a rotary breaker at the CHP. The separated rock is conveyed to a rejects bin from which it is loaded out and trucked to be buried on site as potentially acid forming (PAF) waste. The ROM coal is then transferred via conveyor to a train loadout bin and railed to the SMC via a shuttle train.
The SMC Coal Handling and Processing Plant (CHPP) produces a coking coal and a range of thermal coal products for export.
Reject fractions from the ROM coal are generated at the SMC and deposited along with processing waste fractions produced from the washing of SMC coals. The Stratford Mine utilises a co- disposal method that combines the coarse rejects with the intermediate sized materials and tailings.
ROM Coal Processing On Site.
ROM coal is processed through a rotary breaker at the Duralie CHP ........
