Over 50% of all gold reserves are found in South Africa, with the Witwatersrand Basin remaining the largest gold resource in the world.. 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 ...
