Some blasting parameters are shown in Table 4. Drillhole liners are to be used in wet holes where practical. The selected explosive supplier is to erect a plant and storage facility on site. Under the supervision of the drill/blast foreman, the supplier will be contracted to supply, deliver, and load explosives into the blastholes. The drill/blast foreman will also oversee the blasting crew who will prime, stem, and tie-in blastholes.

The shovel requirements include four 21 m 3 shovels for both waste and mineralized material types from Year 1 to Year 14. From Year 15 to Year 28, the shovel requirements range between three and four. From Year 29 to Prophecy Platinum Corp, 6 1193460500-REP-R0001-00 Wellgreen Project Preliminary Economic Assessment, Yukon, Canada
Year 39, the number of shovels required is three. In the final three years of the schedule, the shovel requirement decreases to two. The shovel size has been matched with 225 t haul trucks to provide a swing cycle of 35 s and total truck load time of 4.0 min in six passes for waste material and 3.4 min in five passes for mineralized material. Suitable number of loading passes typically falls within the range of three to seven. Shovel base productivities were calculated using the sample parameters in Table 5.

The base productivity was used under normal ideal loading conditions. Maximum productivities for both mineralized and waste materials for the shovel and loader were reduced to 90% due to truck availability.
