• 5.5 Loading and Hauling <br />After blasting and assaying, ore and overburden are designated in the field by the ore- <br />grade control (mine) geologists. The blasted rock is loaded into haul trucks using either <br />rubber tired, front-end loaders or track mounted hydraulic shovels. The ore will be hauled <br />to the existing crusher facility or directly to the VLF as run-of-mine material. The <br />crushing facilities are discussed in detail in Section 5.6 below. <br />Overburden material is hauled from the mines to one of two storage areas (the SGOSA or <br />the ECOSA) or hauled as backfill into one of the surface mine areas of Main Cresson, <br />East Cresson, or North Cresson Mines. Backfilling will occur in areas where mining <br />activities allow, usually following the completion of the mining activities. Overburden <br />placement is discussed in detail in Section 5.7 below. Backfill of mine areas is discussed <br />in Section 5.7.4. <br />Subgrade preparation for the Phase 5 VLF or other facilities could also encounter <br />overburden and underground mine development rock that must be moved to achieve <br />grade and appropriate foundation conditions. In addition, overburden placed in the <br />SGOSA in areas of the North Cresson will be relocated to allow mining of the Schist <br />• Island and remining of the Globe Hill portion of the North Cresson. This material will be <br />loaded and hauled in a similar manner to ore and overburden. If ore-grade material is so <br />encountered, it will be hauled to the crusher or placed directly on the VLF. All non-ore <br />materials will be hauled to one of the overburden storage areas or backfilled. <br />5.6 Crushing and Conveying <br />5.6.1 Crushing Facility <br />The existing crushing circuit located adjacent to the VLF will be operated as <br />currently approved in Amendment No. 8. Production rates from the crusher <br />complex are currently permitted up to a capacity of 25 million tons per year. On <br />average, 23 million tons of ore per year are processed through the primary and <br />secondary crushers. The remaining ore is placed on the VLF as run-of-mine ore. <br />The ore from the mine areas is hauled directly to the dump pocket of the primary <br />gyratory crusher or temporarily placed in a nearby ore stockpile. A loader is used <br />to maintain the crusher dump pocket area and to feed the dump pocket from the <br />temporary stockpile when necessary. The truck dump pocket is enclosed on all <br />sides and is equipped with a water spray system for dust control. <br />• Cripple Creek & Victor Gold Mining Company <br />Cresson Project Mine Life Extension <br />5-13
