Australia-based West Wits Mining has become a gold producer after achieving the first production of ore from the Witwatersrand Basin gold project in South Africa. The project is located in the West Witwatersrand Basin goldfield. The mineral resource estimate (MRE) of the gold deposit is 4.28m ounces (oz) @ 4.58g/t Au.

THIS Gold in 2000volume is organized around a classification of hypogene gold deposits that emphasizes their tectonic setting and relative time of formation compared to their host rocks and other gold deposit types (e.g., Sawkins, 1972, 1990; Groves et al., 1998; Kerrich et al., 2000).The temporal division of orogenic gold deposits into Archean, Proterozoic, …

The assumption is made, therefore, that the silver contents found in Witwatersrand gold particles are not those inherited from primary gold sources and provide, at best, limited information on the types of mineralization which existed in the provenance terrane of the sediments.On a regional scale, the fineness values of the gold particles ...

In the discussion about conglomerate-hosted gold deposits, the controversy has mainly centred on whether the gold deposits of the Mesoarchaean Witwatersrand Basin were formed by (a) hydrothermal ...

Since their discovery in 1886, the Witwatersrand deposits have yielded more than 40,000 tons of gold (enough to fill this hall to a depth of 2 meters). This gold-bearing rock is a conglomerate containing rounded gray quartz pebbles in a matrix of sand, mica, and metallic sulfide minerals (including pyrite, or fool's gold).

The Witwatersrand Supergroup contains more uranium than gold and the Witwatersrand gold mines are in fact also uranium mines. Uranium was originally mined as a by-product of the gold mining industry in Gauteng and the West Rand (Von Backström, 1976).

The annual decline of Witwatersrand production has averaged 20 t of gold per year since 1994; at this rate, Witwatersrand gold mining will end in mid-2022. The forty-year production decline is attributed here to exploration failure as there has been no new goldfield discovered since Evander in 1951. A lesson from many of the world's great ...

In 1886, gold was discovered in the Witwatersrand Basin, and since then half of all the gold that has been mined in the world has been derived from this and nearby sources. Scientists predict that the gold deposits in Witwatersrand formed nearly 3 billion years ago, when elemental gold formed compounds with sulfur that were washed down …

The world's greatest deposit of gold is hosted by the Archaean Witwatersrand sedimentary basin, situated in the central portion of the Kaapvaal Craton of South Africa.

the discovery of new gold deposits. The objectives of this paper are to provide an update on gold deposit models, and what new approaches and techniques can now be used to discover gold deposits. Gold occurs in a wide range of deposit types and settings. Exploration is mainly preoccupied with defining the footprints of known gold

posed to explain the Witwatersrand gold deposits, ranging from syn-sedimentary placer to epigenetic magmatic or metamorphic origins. More than 50 years ago the question of the Witwatersrand gold genesis was coined 'the most debated issue in economic geology' (Davidson 1965), and looking at the huge amount of literature on this topic since

hosted gold deposits, as erosional relics of a potentially much larger primary source of gold1,6. Gold in the Witwatersrand is enriched to mineable concentrations in thin quartz pebble beds ('reefs') that commonly extend over kilometers.

the Witwatersrand gold could have formed only during the Archaean, after the emergence of continental life but before the rise of oxygen in the Earth's atmosphere.
