GRADE AND TONNAGE MODEL OF PORPHYRY Cu
By Donald A. Singer, Dan L. Mosier, and Dennis P. Cox
COMMENTS All porphyry copper deposits with available grades and tonnages were included in these plots in order to provide a model for cases where it is not possible to use the gold-rich or molybdenum-rich models. Parts of the porphyry copper deposits which could be considered skarn wereincluded in these data. Gold grade is correlated with tonnage (r = -0.49, n = 81) and with molybdenum grade (r = -0.45, n = 55). See figs. 51-53.
