Specific Mineral Search (SMS) analyses were performed on each of the submitted polished sections.
Particle Mineral Analysis (PMA) is a two-dimensional mapping analysis aimed at resolving liberation and
locking characteristics of a generic set of particles. A pre-defined number of particles are mapped at a
point spacing selected in order to spatially resolve and describe mineral textures and associations.
Specific Mineral Search is a modified particle mapping routine aimed at resolving liberation and locking
characteristics of a set of particles, specifically a phase that reports as a low-grade constituent. The
results of the QEMSCAN analyses are presented in Appendix G.
2.2.1. Sample Receipt and Description
A ground sample of the overall master composite with an average K80 of 100 µm was submitted for
mineralogy. The sample was screened to form three size fractions; +75, -75/+25, and -25 µm. A portion of
each fraction was submitted for Cu, Ni, S and WRA analyses for data validation. Polished epoxy grain
mounts were prepared for each size fraction and were submitted for analyses using QEMSCAN
technology. These results are further discussed in the assay reconciliation portion of this section.
2.2.2. Analytical Quality Control
Analytical quality control is conducted by comparing the chemical analysis determined mineralogically by
QEMSCAN with the chemical analyses obtained from standard assaying techniques.
Key QEMSCAN elemental assays, calculated from the mineral composition have been regressed with the
chemical assays and this is presented in Figure 1. The overall correlation, as measured by R-squared
criteria, was 0.99 and is considered acceptable.
