Grade and tonnage model of Placer Au-PGE

In order to conform to other deposit models herein, deposit volume and grades have been converted to metric tons and grams per metric ton using 2.0 metric tons per cubic meter--the average density of wet sand and gravel. Gold grade is correlated with tonnage (r = -0.35) and with silver grade (r = 0.66, n = 16). See figs. 196, 197. Figure 196.
