The Witwatersrand plateau consists of a 5000-to-7000-metre-thick (3.1–4.3 mi) layer of mainly sedimentary rocks laid down over a period of about 260 million years, starting approximately 2.97 billion years ago. The entire series of rocks, known as the "Witwatersrand Supergroup," consists of very hard erosion resistant quartzites, banded ironstones and some marine lava deposits, interspersed with softer, more easily eroded tillites, mudstones and conglomerates. The oldest rocks (laid down 2.97 billion years

Witwatersrand Basin (RSA) The history: By far the most gold that has been mined in South Africa (98%) has come come from the Witwatersrand goldfields. The name "Witwatersrand" is Afrikaans (originating out of Dutch, French and German) for "White Waters Ridge". (mining operations at 3600 m and exploration core-drilling up to 4600m). Peak
Within a year of gold findings, the area had some 7 000 people with 3 000 living in Johannesburg. By 1895, just nine years after the Langlaagte find, Johannesburg was home to some 102 000 people. To date the Witwatersrand Basin, the largest gold resource in the world, has produced more than two billion ounces of gold.
