To simplify mineral reserve estimates for the mining phases and subsequent
production scheduling analyses, a modified TREO grade (MTREO) was computed to
account for variations in the performance of the physical upgrade (PUG) plant on the
ore types listed below. The PUG plant is expected to be very effective for Whitetail
ore types, but less so for Bull Hill OxCa material.
BH, Oxide:
MTREO% = TREO%
BH, OxCa:
MTREO% = TREO% – 0.25%
Whitetail, Ox & OxCa:
MTREO% = TREO% + 0.50%
