14.11 OreZONE Block Model
The OreZONE block model was created using nearest-neighbor assignment (NN) to
assign the OreZONE from composites to blocks without regard to oxidation type. The
OreZONE search ellipses were developed based on variogram ranges for the
OreZONE flag parameter. Parameters for the NN assignment are summarized in
Table 14.16. A typical plan map through the OreZONE block model is shown in
Figure 14.17.
