What is Witwatersrand?

Meaning the ridge of white waters, Witwatersrand is where Sean and Duff head to find gold. They build the Candy Deep mine and become millionaires, and then lose it all because of their own greed. In an effort to take down a rival, they leave themselves open, and Hradsky takes them down. One of the richest finds, Witwatersrand makes and breaks many, and is the reason for the explosive growth of Johannesburg.
