The world's deepest gold mine is in South Africa ...
Welcome to another day at Mponeng, the world's deepest gold mine. The Depths of the Witwatersrand. If you own any gold, there is about a 50% chance it comes from the Witwatersrand Basin in South Africa. Gold was first discovered there in 1886, and it is speculated that the discovery may have only been possible because of an asteroid impact.
