HAULAGE General Hauling Conditions The 225 t hauler was selected to match the 21 m 3 diesel hydraulic shovel and 18 m 3 front end loaders in determining the number of trucks required for each operating year. Cycle times are based on estimated haulage profiles from the ultimate pit design based on material types. It is assumed that the waste dump would be within 4,000 m of the pit entrances and primary crushing facilities, located at the mill, within 8,000 m. Haul Truck Productivity Truck productivities are based on expected operating conditions, haulage profiles, and production cycle times. Cycle times were calculated using Caterpillar FPC TM commercial software. A weighted average cycle time for each year was calculated according to its final destination (waste dump or crusher). Haulage analysis assumptions are outlined in Table 6. Table 6 Assumptions Used for Cycle Time Calculations Units Value Maximum Speed on Dump and Around Shovel km/h 20.0 Maximum Speed In-pit (and Ramps) km/h 40.0 Maximum Speed on Downhill for Safety/Account for Corners km/h 20.0 Loading Time (PC1250) min 4.5 Dumping Time min 0.5 Swell Factor % 30.0 Waste Rock Density (in situ) t/m 3 2.5 Mineralized Material Density (in situ) t/m 3 3.2 All ramps were assigned a grade of 10% in the pit and on the dumps. The road grade for the road to the mill was assigned a grade of 5%. SHOVEL AND TRUCK REQUIREMENTS The haul truck requirement is initially 25 units of 225 t trucks and ramping up to a maximum of 32 units of 225 t trucks in Year 31 due to the estimated longer cycle times/increasing depth of pit. The truck requirements oscillate between the years due to the combination of the fluctuations in total material mined, the location within the pit that material in a year is being mined from (the effect of the different phases) and this impact on the estimated cycle times. The truck requirements begin to drop off in approximately Year 39 as the stripping ratio decreases. The yearly equipment requirements are shown in Table 7.
