Mine excursion and planned to send their ore to the Randfontein plant. But before they could, Bernard Swanepoel and Harmony won a hostile bid for Randfontein Estates and, as a result, sterilised the Durban Deep footprint, since Swanepoel’s processing plants, only 7km away, were off-limits. After that, DRD ventured into all sorts of exotic destinations to save face, but failed dismally. Eventually, a lawyer from the small Free State town of Philippolis took the reins, sold all DRD’s underground mines, and transformed the company into the most efficient surface mining operation in the world. Neil Pretorius is probably another name that will be remembered long after all the mine dumps on the Rand have disappeared. Pretorius has extensive knowledge of the Johannesburg area, but most of all, knows how to negotiate the harsh legal battlefield that companies like West Wits often face when attempting to mine what is left of the reef. Pretorius sits on the West Wits board. West Wits has encountered fierce opposition from various quarters in the area. Quinert and his team deny allegations of blasting, dust, and noise. In fact, they have brought in new equipment, called Xcentric Rippers, to replace drilling and blasting. Joburg – a stunning goldfield “We see the area as terribly neglected, and mining can be a constructive process to assist with that,” says Quinert, adding that it is a misconception that the gold in the Witwatersrand is mined out. “If we look at it in comparison to what we have in Australia, and other areas that we have operated in, this is a stunning goldfield,” he says. More than 40% of all the world gold, ever, has been produced within the boundaries of the city of Johannesburg. Although most traditional mining companies have moved out of the area, Quinert believes there is a lot of gold left. And he is not alone: a group of geologists has just rethought the formation of the Witwatersrand goldfields, and they are convinced that the best is ye t to come. “We have gone down to 400m over most of the area; in some cases, we have opened up the surface to greater depths. But by using a shallow mining approach with conventional methods, we have delivered a JORC Resource of 3.7-million ounces at 3.6 grams per tonne. There are mines in Australia raising money with about half of that resource,” says Quinert. The two historical mines that constitute the West Wits area, Durban Roodepoort Deep and Rand Leases (called the Soweto Cluster), have produced more gold than Kalgoorie, the flagship of Australian gold mining. The old mines in South Africa kept immaculate records, and it is this data that provided most of the information necessary for West Wits to make a viable case. However, the company spent a lot of money on drilling when they brought in Australian geologists eight years ago and is still using some of that information. Those geologists were highly paid, though, and also lived Ever since West Wits started mining the Kimberley Reef, they have moved more than 1.5 million tonnes of material.
