The gold fields of the Witwatersrand Basin in South Africa are, by a landslide, the largest single gold producing district in the world. It has produced some 2 billion ounces over a century of mining and at an average grade of 15 g/t Au with a current head grade of 6-10 g/t Au and they still have estimated reserves of some 1,161 billion ounces (36,000 tonnes). Production does not come easy though. Layers of sedimentary rock in the Witwatersrand show that is was once a shallow sea. This sea was formed approximately 3 billion years ago after the collision between the Zimbabwe and Kaapvaal cratons. Ancient river systems feeding into the basin eroded the surrounding highlands and over a period of about 260 million years, deposited layers of quartz pebble conglomerates, sandstones and shales.
The gold in the Witwatersrand Basin area was deposited in ancient river deltas, having been washed down from surrounding gold-rich greenstone belts to the north and west. Another serious problem is that of heat. In the deeper mines refrigeration of the intake air is often necessary to keep conditions tolerable and this is now becoming necessary on some platinum mines which, although shallower, have a higher geothermal gradient. Refrigeration is very energy hungry and it is currently a moot point whether ESKOM, the state power company, can supply the necessary power after its recent problems

Control of the gold mines was a significant factor in the tension between Dutch and English settlers that would result in the Second Boer War in 1899. Prior to this, Rhodes and Hammond were behind the abortive Jameson Raid, but Hatch had returned to England briefly and was not implicated. This 1895 work, written with South African mining engineer J. A. Chalmers, reveals the extent of gold reserves in the Transvaal, and the engineering skills needed to exploit them
