on the top of Ceresco Ridge, this system was modified by mining <br /> the upper benches to final limits with the first slice, and <br /> mining the lower benches in several increments. This modified <br /> slice system may also be used on top of Bartlett Mountain on the <br /> north perimeter of the pit. <br /> Due to subsidence from underground mining, unstable <br /> rock and natural weathering over the mining life of the Open Pit, <br /> it is anticipated that 800-1000 of the pit surface will have a <br /> talus slope appearance. It would be only a matter of time for <br /> any remaini_ng benches to visibly disappear due to rock weathering <br /> and sloughing. <br /> Primary drilling in ore and waste is by 45R, T4 and DM4 <br /> drills Ore and waste is loaded byl15-yard electric shovels into <br /> • a fleet of 120 -ton trucks for haulage to the Fc_r_u_-,_h_e_i7, stockpile, <br /> or dump. Various sized dozers, along with rub er-tire bulldozers <br /> are used on the dump roads and initial stripping areas. Eight, <br /> LEenj raff we ve yard loa ers are used far shovel back-up and <br /> stockpile loading. Other pit equipment includes backhoes, lcranes, <br /> graders, fuel and Mu-b-67 trucks, and small vehicles. <br /> Open Pit waste rock or waste material will be hauled <br /> from the pit to the Cirque Dump (2) or McNulty Dump (6) for <br /> disposal, or hauled for reclamation purposes to the Old Tailing <br /> Pond (A) or to the Robinson Tailing area (15, 16 , 17) . Waste <br /> rock disposal sites will be discussed in the following section. <br /> Ceresco waste material above the 12 , 000 foot bench will <br /> be hauled to the Cirque Dump until it is filled to capacity. <br /> 2-6 <br />
