The Governor Mine contains $3-$4 billion dollars in Gold Reserves that have never been mined. High Gold reserves were found underground that equaled 5 ounces of gold per ton of dirt in certain locations. There is the potential for much more than $4 Billion in Gold below the 1000' level.
The Governor Mine was shut down because President Roosevelt ordered all gold miners to work at iron mines to make weapons in World War II. In the 1980's an untapped adjacent ore body that has greater gold reserves was discovered. This primary ore body has not been mined.
