Variography of composite Ag, of all coded veins (1–33)
showing the pair of axes with orientation at 90° and 0°,
with an approximate range of 80 meters.
In Figure 14 and Figure 15, composite Au variography
for all veins (1–33). The variography is shown in the ori-
entation at 90° and 0° with a range of 40 to 45 m. It was
evaluated in the MEDS 350° -0°- 90 plane.
Variogram Modeling
Resource Classification
For resource classification, the parameters of minimum dis-
tance from the compound to the block (DIST field) and
number of drillholes involved in delivering grades to a block
(NMUE field) were taken into account. These parameters
are evaluated and the result is recorded in the “CATEG”
name field of the block model, and will be used to classify
the resource type.
Measured Resources will take 2/3 of the range up to
40 m, Indicated Resources will take the last third of the
range (from 40 to 60 m). Finally, the areas between the
drill holes within the mineralized zone and restricted by the
solids of each vein will be considered Inferred Resources.
