    Mining Immediately prior to mining any deposit, the land is cleared and the top soil, to a minimum of 6 inches, removed and stockpiled for later replacement when mining is completed. The surface occurrence of the ore (usually less than 100 feet) makes the deposits suitable for mining by simple opencast methods. Due to the soft, earthy nature of the ore, no drilling or blasting is generally required.
