Mineral reserves contained within each phase were estimated using the tonnage
factors stored in the block model, ranging between 11.01 and 17.79 ft
3
/ton (i.e.,
densities of 2.91 and 1.80 tonnes/m
3
, respectively) and averaging 14.52 ft
3
/ton (2.21
tonnes/m
3
) within the ultimate pit limits. No additional dilution or ore loss factors were
applied outside of the provisions already made within the block model.
Table 16.2 summarizes the proven plus probable mineral reserves contained within
each of the mining phases above a 1.50% MTREO cutoff. The sum of the mineral
reserves by phase agrees with the total proven and probable mineral reserve
estimates presented in Section 15.

16.4 Mine Production Schedule
A mine production schedule was developed to feed about 179,000 stpy (500 stpd) of
upgraded mineral reserves (crushing/screening plus PUG beneficiation) to the hydro-
metallurgical plant through the first nine years of operation, after which the plant
would be expanded to accept nearly 216,000 stpy (600 stpd) of feed. The Hydromet
plant would operate 24 hours per day, 360 days per year.
