Mine Life2027
Khwezela South (formerly known as Kleinkopje) consists of the Bokgoni 2A pit and the MRD (also known as Landau 3), both of which were placed on care and maintenance with effect from the first quarter of 2021.

Coal mining operations were conducted in the designated RoMP at Khwezela South MRD during the period of care and maintenance. The coal was trucked to the Isibonelo Colliery where it was blended with in-pit coal at a ratio of 1:6 and then sold to Sasol Synfuels Operations.

Summary:

Khwezela South is located in the Witbank Coalfield where five coal seams are present. These consist of, from bottom, the No 1 Seam, sequentially to the No 5 Seam at the top and are all, with the exception of the No 3 Seam, part of the resource base. A small graben with a 10m throw lies to the northeast of the Bokgoni 2A pit. No major dolerite intrusions have been encountered. The No 1 Seam averages 2.0 to 2.5 m in thickness and is generally of good quality, able to produce a steam coal of 27.40 MJ/kg at yields greater than 60%. The Number 1 Seam Roof (S1R) coal is of lower grade with lower yields and is only mined when the No 1 Seam is destined for the local power station market. In places, the seam may be too thin to mine. The P1 parting between the No 2 and No 1 Seams is between 1.5 and 4.0 m thick and consists of sandstone. The No 2 Seam is developed over almost the entire Bokgoni area, subcropping to the north of the Bokgoni Pit. The seam varies in thickness from five to eight metres, averaging six metres. The seam is subdivided into subseams, generally based on quality. The highest quality coal occurs in the middle of the seam (the S2S), with duller coal above and below it. The No 3 Seam, although of good quality, is thin (approximately 30 cm) and has not been mined; it is used as a marker horizon. The quality of the No 4 Seam is highly variable across Bokgoni, with poorer quality coal in the west where the P4L parting occurs. The thin, upper portion of the seam (the ........

Summary:

The Bokgoni Pit was placed on care and maintenance in December 2020 due to the prevailing economic conditions; as such, no Coal Reserves have been declared as a new mine plan would need to be developed by the Company in order to extract any future coal, should economic conditions improve sufficiently. The Bokgoni 2A Pit was put on care and maintenance in 2021 and no mining took place in 2022. The Khwezela South MRD (also known as Landau 3) consists of discard material from the No 2 Seam, laid down during the early stages of the facility’s construction, and an old ash dump. A poorquality top zone was formed when the discard of re-washed MRD material was deposited during the last years of operation. The MRD was built up in two stages, resulting in an old slightly better quality section, and a new poorer quality area. Seven vertically stacked horizontal layers represent the variation in raw coal qualities. An assumed bulk density of 1.5g/cm3 was used to estimate the tonnage. During 2022, 1.4Mt coal was mined from the declared RoMP. The coal was trucked to the Isibonelo Colliery where it was blended with in-pit coal at a ratio of 1:6 and then sold to Sasol Synfuels Operations.
