A grade-tonnage model is established according to the analysis of 72 porphyry copper deposits recorded in "The Mineral Resources Data Base of China". Based on the analysis of frequency histogram, the cumulative frequency distributing graph and the theoretical model with double logarithmic coordinates of copper deposits, the typical mathematical characteristics of grade-tonnage model of porphyry copper deposits are clarified.
