Mine Life1 years (as of Jan 1, 2022)
The Khanyisa Complex comprises the historical Khanyisa mining area (mined out), the Catwalk and the Triangle areas, all of which have been consolidated into one mining complex.

Initiatives are being pursued to extend the life of mine of Khanyisa Complex beyond FY23.

Summary:

The Elandspruit, Khanyisa, Vanggatfontein and Moabsvelden Collieries are located within the Witbank Coalfield. The northern extent of the Coalfield is defined by the limit of coal-bearing sediments of the Vryheid Formation which abut against pre-Karoo basement rocks of the Transvaal Sequence, the Waterberg Group and Bushveld Complex. The southern limit of the central sector of the Coalfield is marked by a series of Bushveld Complex inliers known as the Smithfield Ridge while in the east and west sectors, the boundary between the Witbank Coalfield and the Highveld Coalfield to the south is somewhat arbitrary. The five major coal seams of the coalfield are contained within a stratigraphic interval averaging approximately 70m in thickness. The seams are numbered, from the base upwards and include the No. 1 Coal Seam, the No. 2 Coal Seam (split into the No. 2 Lower Coal Seam and No. 2 Upper Coal Seam), the No. 3 Coal Seam, the No. 4 Coal Seam (split into the No. 4 Lower Coal Seam and No. 4 Upper Coal Seam) and the uppermost No. 5 Coal Seam. Five principal seams are developed at Khanyisa, namely the No. 1, No. 2, No. 3 and the No. 4 Lower and No. 4 Upper Coal Seams. The No. 5 Coal Seam is not present at all. The No. 1 Coal Seam is not considered economic as it is either very thin (~1 m thick) or not developed. Similarly, the No. 3 Coal Seam is also not considered economic as it is on average only around 0.3 m in thickness. No. 1 Coal Seam The No. 1 Coal Seam occurs directly o ........


Mining Methods

  • Pillar & roof
  • Strip mining (roll-over)
  • Truck & Shovel / Loader


Summary:

The Khanyisa Complex comprises the Triangle resource area and the Catwalk resource area.

From a reserve perspective, the peripherals of the mined-out areas and the boundary pillar remain on Triangle 2 of Khanyisa (Triangle 1 is considered mined out), and Catwalk is in the process of being backfilled. The opencast methodology remains as a standard rollover methodology. From a resource perspective, the peripherals in both Triangle 1 and Triangle 2 are still included as there is the option to gain 50m of the current 100m Transnet pipeline servitude.

Coal Reserves for the Khanyisa Complex were based on the proven opencast strip mining strategies, and operations were executed as such throughout FY22. Reserves remaining as at the effective date of this report are at Triangle 2 only, including the boundary pillar of 9m that was approved by both Mining Right holders and will be mined with the neighbouring mine.

Fixed infrastructure is utilised with all major mining activities contracted out, together with the crushing and screening plants. Additional mining contractor infrastructure exists to provide for the full service.

A total of 0.83mt ROM was extracted from the Triangle sections during FY22, with a net loss of 0.28mt realised. 0.03mt was taken out of the Catwalk pillar area and mining has reached the limits of what is economically extractable. All peripheral coal in offsets not accessible in both Triangle 2 and Triangle 1 were removed ........
