Sublevel Caving can be used in orebodies with very different properties and is an easy method to mechanize. This method is normally used in massive, steeply-dipping orebodies with considerable strike length, and usually has a high amount of dilution and low recoveries. Thus Sublevel Caving is usually used to mine low-grade, low-value orebodies.
