Apart from gold mining, there are many other minerals being produced, for some of which South Africa is the leading producer and holder of reserves. The Green Paper also has a chapter on small-scale mining which is intended to encourage the small and medium sized operator, to the benefit of employment and the overall economy.
M M ining in South Africa has been a contentious issue since 15-year-old Erasmus Stephanus Jacobs discovered South Africa's first diamond, the Eureka, in Hopetown in 1867. It kickstarted what historians call the Mineral Revolution, which made few European opportunists wealthy beyond measure, and saw hundreds of thousands of men leaving their homes to become fulltime mineworkers.
About 244,000 metric tons of gold has been discovered to date (187,000 metric tons historically produced plus current underground reserves of 57,000 metric tons).
