that are diluted below cutoff grade. Because drilling typically intersects the
mineralized zones at angles of 45° to 55°, a typical five-foot assay interval is only 3
to 3.5 feet of horizontal width, and dilution computed on the basis of raw assays tends
to be exaggerated. When the 20 to 30-ft OreZONE composites are compared to
composites with a ten-foot minimum width, dilution is 30% with an ore loss of 8%.
Accordingly, it is believed that sufficient geometric dilution is included for mining 20-
foot minimum mining widths. Composite dilution calculations are summarized in
Table 14.25.
