Three main directions
of anisotropy, Indicator Vario-
gram Model, 0.2 g/t Au, HAZ-Hi.
The directions are N30W (
top
),
N60E (
middle
), and vertical
(
bottom
). Note that the relative
nugget plus the first structure
represent over 93 % of the total
variance, which means that the
range at which kriging will be
effective is much smaller than the
range of the variogram model
