ZIMBABWE'S GOLD POTENTIAL
Similarly, stories about unlimited gold riches, which were thought to be the provenance of the famous Witwatersrand deposits, led to the invasion of the country by Cecil John Rhodes' British South Africa Company in 1890. Ancient miners did a great deal of exploration and mining long before the arrival of the Europeans.
