The NiEq value was assigned to all sample intervals to assist with the geological
interpretation of the mineralization of both the West and East Zones. The NiEq value
is based on a long range pricing index updated quarterly. At the time the resource
models were completed, the following commodity prices were used:
• nickel – US$9.40/lb
• copper – US$2.96/lb
• cobalt – US$15.80/lb
• gold – US$1,200/ troy oz
• platinum – US$1938/ troy oz
• palladium – US$816 troy oz
The equation for the NiEq value is as follows:
NiEq = ((Ni grade x Ni price x 22.04622) + (Cu grade x Cu price x 22.04622) +
(Co grade x Co price x 22.04622) + (Au grade x Au price x 0.02916) + (Pt grade x
Pt price x 0.02916) + (Pd grade x Pd price x 0.02916)) / (Ni price x 22.04622)
Recovery has been assumed to be 100% in situ on all metals, as there has been no
metallurgical recovery testing completed on the targeted material at the time the
resource model was constructed.
Sectional interpretations were digitized in Datamine Studio 3 (v. 3.19.3638.0)
software, and these interpretations were linked with tag strings and triangulated to
build three dimensional solids. Table 14.6 tabulates the solids and associated
volumes. The solids were validated in Datamine and no errors were found.
The zones of mineralization interpreted for each area were generally contiguous.
However, due to the nature of the mineralization, there are portions of the wireframe
that have grades less than 0.2% but are still within the mineralizing trend.
The non-assayed intervals were assigned void (-) value. Tetra Tech believes that
non-assayed material should not be assigned a zero value, as this does not reflect
the true value of the material.
