• The primary crusher is followed by a conveyor to a splitter box and double deck vibratory screens. The splitter box and screens provides separation to direct properly sized ore directly to the load out bin and oversize ore to the secondary crushers for further crushing. The secondary crushers crush the ore to nominal 3/4 to 7/8 inches in size. Dust is controlled by water sprays and the enclosed transfer points of the primary crusher and screening facility. In addition, the primary crushing facility is equipped with a foam application system that can be utilized to assist with dust suppressant efforts during adverse weather conditions. The secondary crushing facility includes the ability to house four cone crushers in an enclosed structure. However, under the current production rate of about 25 million tons of ore material through the crushing circuit, only three of the four secondary crushing units have been installed and implemented. Dust is controlled through water sprays and the enclosure and the conveyance system to and from the secondary crusher and at the drop points in each of the secondary crushing units. The secondary crusher product is then conveyed to the loadout bin ("LOB") for hauling to the VLF. • A lime silo is located after the secondary crushers. Lime is applied to the ore passing near the base of the silo using an enclosed variable speed rotary lime feeder. The lime addition rates are governed by the crushed ore conveyor belt scale to maintain a target amount of lime per ton of ore that is crushed and placed on the VLF. 5.6.2 Crushed Ore Conveyor to VLF After crushing and lime addition, the ore is delivered by conveyor to the LOB. The ore is conveyed to the LOB where it is loaded onto haul trucks for delivery to the VLF. The conveying and hauling will occur in essentially the same manner as discussed in Amendment No. 8. The LOB will be relocated from the current location to a higher location adjacent to the VLF to facilitate life of mine stacking of ore on the VLF (this was approved as part of Amendment No. 8, but is not scheduled to be implemented until approximately 2009). 5.7 Overburden Handling and Control Rock without recoverable gold, but which must be removed to access the gold-bearing ore, is called overburden. Overburden will be loaded from the mine areas for transport to • one of two overburden storage areas or to an active backfilling area.
