Witwatersrand Wikipedia

The Witwatersrand Basin is a largely underground geological formation which surfaces in the Witwatersrand. It holds the world's largest known gold reserves and has produced over 1.5 billion ounces (over 40,000 metric tons), which represents about 22% of all the gold accounted for above the surface. The basin straddles the old provinces of Transvaal and the Orange Free State, and consists of a

Geological Formation of South Africa

The Central Rand Group was rather special, however, because heavy grains of gold were periodically deposited on the river beds, along with the gravel. This created the richest gold field on Earth, containing nearly half of the planet’s gold. Later, these gold-bearing conglomerate rock layers (called reefs) would be mined with spectacular success.
