In 1975, South Africa was responsible for producing 40% of the gold ever mined. By 2010, however, China affirmed its status as the world's largest gold producer with production of 324 tonnes of gold, followed by Australia (222.8 tonnes), and South Africa with 219.8 tonnes. Today, South Africa produces only 4.2% of the world's gold.
Africa may have higher potential for undiscovered gold deposits than any place on Earth. Economic instability in many gold-bearing regions have significantly limited exploration in many countries, and the limited resources available to many of the artisanal miners means that many of the known gold occurrences are vastly underexploited.
South Africa has some of the world's largest gold deposits. While many of the precious metal gold deposits that spurred gold rushes of the past are long gone, many of the world's largest gold deposits still generate bounties of gold each year. The Witwatersrand Basin of South Africa is perhaps responsible for the biggest bulk of gold production.
