Variograms are computed using Sage2001
variogram software in the trend-flattened
coordinate space. Plan view is equivalent to a
longitudinal section oriented parallel to the trend
of mineralized zones. “Vertical” variograms are
oriented perpendicular to the trend.
(A.Noble, 2014)
The OreZONE variograms in Figure 14.12 measure the continuity of the
OreZONEflag, which is a zero/one (0,1) indicator variable that is used to define Low-
Grade (0) and High-Grade (1) zones for the resource block model. Variograms are
well defined, indicating continuity of 2250 feet in the primary axis (X’), 945 feet in the
secondary axis (Y’), and only 240 feet in the tertiary axis (Z’-perpendicular to the
trend). It should be noted that the actual direction of the primary axis varies
according to the rotations in Table 14.14, thus the primary axis in the Zone M1 High-
Grade OreZONE rakes 30° down to the southwest along the unfolded trend plane,
but is vertical in the West and Whitetail Domains.
