Table 14.10 - Procedure for Optimized Grade-Zone Compositing
1.
The average orientation of the drill hole was compared to the generalized trend plane to
compute the length of drill hole required to achieve the minimum true width perpendicular to
the plane.
2.
The Studio 3 COMPSE process was used to compute composites with at least the minimum
true width (from Step 1) that were also above the cutoff grade.
3.
An OREFLAG was set to one (1) to identify composite intervals above cutoff.
4.
The drill holes were composited again, using down-hole compositing that was set for a
nominal 10-foot (3.05 meter), true-width composite within OREFLAG intervals of the same
type. In this process, composites start and stop at OREFLAG boundaries, and the
composite length is adjusted to include the entire interval defined by the OREFLAG zone,
while maintaining a nominal 10-foot-wide, true-width composite length.
