The discovery of gold on the Witwatersrand in South Africa occurred between 1884 and 1886 with George Harrison's 1886 discovery on the farm Langlaagte considered as the most significant. The first large mining company, the Witwatersrand Gold Mining Company, was established in the same year [ 1 ]. The discovery of gold …

South Africa's gold mines, once the apex of global gold production, now grapple with deep-seated challenges – aging infrastructure and depths that test the limits of modern mining.

Historically, Witwatersrand-type gold deposits of South Africa ranked at the pinnacle of world gold production (Hartnady, 2009; Frimmel, 2019). In 1970, South Africa produced roughly 1000 metric ...

Mining - Prospecting, Exploration, Resources: Various techniques are used in the search for a mineral deposit, an activity called prospecting. Once a discovery has been made, the property containing a deposit, called the prospect, is explored to determine some of the more important characteristics of the deposit. Among these are its size, shape, …

The ore-body has been folded into a tight to isoclinal NE-plunging, F1 antiform, with both limbs Gold mineralization in Natal, South Africa 107 dipping -40NW. Pyrite (10-50%) is the dominant sulphide, with minor galena and sphalerite. Gold grades average 1.25 ppm over a width of I m and 120 m along strike.

Although mining has reached a very mature state, this ore province remains the biggest regional gold anomaly in the world. Most recent research on the Witwatersrand gold deposits has focused on postdepositional processes, often on a microscale, thereby constraining conditions of gold transport in the host conglomerates.

The Witwatersrand gold fields of South Africa account for more than a third of the world's total gold production since mining started there in 1886: 48,000 t Au. These gold fields dominated production throughout the twentieth century, but production peaked at 1,000 t in 1970 and has steadily declined since that time.
