The Mafube Nooitgedacht and Wildfontein operations involves the expansion of mining operations from the existing Springboklaagte coal reserve to the Nooitgedacht and Wildfontein reserves. The Mafube Nooitgedacht and Wildfontein commenced operations in May 2018 and February 2018 respectively. The Mafube Nooitgedacht coal reserve area covers approximately 2 957.12 ha, and the Wildfontein reserve area covers approximately 887.14 ha

Due to the shallow depth of the Nooitgedacht coal reserve (9 – 49 m), opencast roll-over mining methods will be employed to extract the coal. The rollover mining method entails the process whereby the topsoil and overburden from the first cut of the opencast mine are stockpiled at the position of the last cut. As the opencast mine progresses, the overburden and topsoil from each successive cut are backfilled into the void from the previous cut, the surface is shaped to be free draining, the topsoil is analysed and treated appropriately, and the surface is revegetated. At the end of the life of the opencast mine the final void is backfilled with the overburden from the final cut of the last remaining pit.

The mined out coal will be passed through an on-site primary crusher to feed onto a conveyor belt from the Nooitgedacht operations that will convey the coal to the existing Mafube washing plant located at Mafube Colliery. Discard from the coal washing plant will report to the existing Mafube Colliery (Springboklaagte) discard facility and fines will be turned into briquettes. This existing coal discard facility was designed to cater for the Mafube Nooitgedacht project operational needs and, should there be remaining discard once the final voids have been back-filled, this will be conveyed to the existing facility at Mafube Colliery (Springboklaagte).
