16.5.4 EXPLOSIVES
A contractor will supply, deliver and load explosives into the blastholes under the
supervision of the drill/blast foreman. The contractor will erect a plant and storage
facility on-site.
16.6 U LTIMATE P IT D ESIGN
Based on the optimization results and current geological model, Tetra Tech used Pit
Shell 26 as the guide for the ultimate pit design, the results of which are provided in
Table 16.7. Tetra Tech assumed an overall mining recovery of 95% and a waste
rock dilution of 5%. The design has 4% less mineralized material and waste
contained in the pit compared to Pit Shell 26. The pit design can be improved with
further design work. This ultimate pit was designed to check the practicality of the
final pit shell that was used in the production schedule.

Figure 16.11 illustrates the ultimate pit design. The pit can be accessed either a
west side or east side entrance. There are two distinctive bottoms for the pit that are
separated by a discountinuity in the deposit. The east side of the pit is the deepest
part and will be mined at the end of the mine life.
