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.

Is Chalcopyrite toxic? Chalcopyrite itself is not toxic, but like many sulfide minerals, it can produce sulfuric acid when exposed to air and water. This acid can be harmful to the environment if not properly managed during mining and processing operations. Does all chalcopyrite have iridescent colors? No, not all chalcopyrite exhibits iridescence.
