South Africa has some of the world's deepest mines, which serve as classic examples of supported mining methods (see section 4.2). Within South Africa, eight out of the ten deepest mines in the world are located in the Witwatersrand Basin, which is famous for its gold endowment ( Frimmel, 2019, Table 1 ).
A new method of underground gold mining, being tested by AngloGold Ashanti, is filling headlines in the country, as the method has the potential to reverse the decline in South Africa's gold output.
Driefontein is located in South Africa's West Wits Line goldfield, about 60km south west of Johannesburg.

"Of course, mechanization in narrow-reef hard-rock mines is a much more challenging task but even here South Africa has done well. In 2000 South Africa's hard rock mines, mainly those in the platinum/chrome sector, were producing about 2 Mt of ore annually using mechanized methods but that figure has since increased to over 30Mt …
The total project cost has been estimated at R1.1bn, with almost R1bn of this budget having been accounted for to date. South Reef produced 62,694oz in 2010 and 80,763oz in 2011. The average recovery grade is 4.5g/t. At a gold price of R115,000/kg, the NPV is R1,189m and the IRR exceeds 50%, making the project financials very attractive.
