Thungela Resources Limited holds 90% of the thermal coal operations in South Africa with the remaining 10% held collectively by an employee partnership plan and a community partnership plan.
Anglo American plc announces the completion of the demerger of its thermal coal operations in South Africa. Thungela Resources Limited will start trading today through a primary listing on the Johannesburg Stock Exchange under the abbreviated name “Thungela” (Alpha code "TGA”), and a standard listing on the London Stock Exchange (ticker symbol “TGA”).
Summary:
Area of the Greenside Colliery is underlain by rocks of the Karoo Supergroup comprising sedimentary rocks of the Carboniferous Dwyka Group and the Vryheid Formation of the Permian Ecca Group. The diamictites of the Dwyka Group were deposited in a grounded glacial setting and the mudrocks, coals and sandstones of the Vryheid Formation were deposited in a delta plain depositional environment. The coarse grained diamictites of the Dwyka Group, which are positioned well below surface in the study area, are unlikely to contain fossils and in any case will not be exposed by the development. The overlying rocks of the Vryheid Formation of the Ecca Group are renowned for their wealth of plant fossils of the famous Gondwanan Glossopterus flora which has been described from Permian-aged rocks. This flora is the source of the coal which is mined from the Vryheid Formation in South Africa. Within the Vryheid Formation there are occurrences of well-preserved elements Glossopteris flora comprising wood and/or leaves.
Summary:
Greenside Colliery targets the extraction of the No. 4 seam to produce coal for supply into the export and domestic markets. The mine uses mechanised bord and pillar mining to exploit the coal. The shallowness of the No. 4 seam enables a high extraction rate and thus increased productivity.

Summary:
The colliery currently operates three coal processing plants, one to wash raw, primary mined coal (No. 4 seam plant), one to primary wash discard material from the mineral residue deposits (No. 5 seam plant) and a plant that treats the ultrafine material from the No. 4 seam plant. The No. 4 seam plant is fed with material mined from the five underground mining areas. This plant produces a primary export product and a lower quality 4,800 kcal/kg product. Product qualities are changed from time to time dependent on market demand. The mineral residue deposit reclamation produces a product for consumption in the domestic market.
No.4 seam Plant.
The ROM coal is conveyed via 4A conveyor to surface. The plant has 4 surface conical ROM stockpiles:
- 4A, 4S1, 4S2, and 4S3 with underground withdrawal conveyors and Nick Shaft stockpile with 2 surface reclaim conveyors fed by front end loaders.
Coal from 4A conveyor is fed to a flopper that diverts coal to the 4A s ........
