The Antamina and Usu Pallares orebodies have proven to be consistently well mineralized and predictable, both in terms of grade and metal zoning over large areas, however short distance variability is quite high as is typical in most skarn deposits. Very little of the skarn lithology comprising the deposits is unmineralized.

Grade control in hard-rock open pit mining is the process of determining the destination for the mined material. Numerical studies are undertaken to show how grade control can be improved, that is, less ore sent to the waste dump and less waste sent to the mill. The improvements in four aspects of grade control are proposed: (1) the grade ...
