Mining Method
The most viable way to recover the ore body is by a well-established underground mining method called block caving. Block caving is safe, environmentally sound, and cost-effective for mining a large, deep orebody. In block caving, a large section of ore is initially undercut by drilling and blasting, causing it to collapse under its weight.
