With the price of gold reaching $2,000 per ounce exploration has become potentially more profitable. Mineral Mountain Resources (yellow) has claims on approximately 7500 acres. F3 Gold (red) has almost 2500 claims. The Rapid Creek watershed west of Rapid City in the Black Hills is approximately 198,000 acres. And about 47,000 acres of that watershed have been claimed by gold companies. In other words, almost a quarter of the watershed – 73 square miles – has the potential to be involved in further exploration and mining operations.
