Get PriceMany base metal (Cu, Zn, Pb) and the majority of precious metal (Au, Ag, Pt, Pd) deposits show occasional or frequent high sample values. These values are considered to be erratic and are designated as nugget value. Some of the estimators of exploration and mining companies prefer to introduce a cutting factor, i.e., an arbitrary upper limit marker value in the ore reserve estimation. Any
