The proposed Amendment activities will result in tree removal. Where tree removal is necessary, <br /> appropriate efforts will be made to remove only those trees and shrubs necessary to provide for an <br /> efficient and safe reclamation. Any trees removed during site construction will be made available to the <br /> employees for fire wood. Because site reclamation is well into the future, shrubs removed during site <br /> development will be hauled to an offsite facility for proper disposal. <br /> The proposed road between the Cross mine and the Caribou mine is partially on previously disturbed <br /> land.The road construction in previously undisturbed areas is predominantly fill and any topsoil <br /> removed will be reused on road embankment revegetation.The addition of the new road will provide <br /> any topsoil or vegetative cover to be salvaged. <br /> The increased permit boundary includes the Caribou hillside discussed in Technical Revision No. 7 (TR 7). <br /> The topsoil, vegetative cover, and reclamation plan are discussed in Exhibit D. <br /> 1.3 Overburden <br /> This is an underground mining operation, producing ore from various near vertical mineralized veins and <br /> deposit thickness is not applicable. Some waste rock will be produced as the new Idaho Tunnel Drift is <br /> developed. Additionally, driving a new adit at the Cross mine and other development work will generate <br /> waste rock. The amount of waste rock generated annually is estimated as 20,000 to 40,000 yards. <br /> 1.4 Waste Rock Piles <br /> There are currently three waste rock piles on the site (Map 7). One temporary waste rock pile is located <br /> adjacent to the Cross Ore Building. The second waste rock pile is also temporary and is currently located <br /> southeast of the Cross Mine warehouse. The third waste rock stockpile is located at the upper or <br /> western entrance to the Caribou Mine. This is the waste rock area proposed for future use under this <br /> amendment. The Caribou waste rock management area will be used for all waste rock generated on site <br /> after construction of the new road. It has a working stacked capacity of approximately 20,000 cubic <br /> yards. Waste rock is trucked off-site periodically for beneficial use by a permitted facility in Golden, CO. <br /> The material in the two Cross mine temporary waste rock areas will be used on-site for the new road <br /> construction. The two Cross waste rock areas will not be used for waste rock storage after construction <br /> of the new road; all waste rock will be consolidated into one waste rock area managed at the Caribou <br /> waste rock area. Waste rock is primarily composed of gneiss and quartz monzonite. <br /> 1.5 Operational Components <br /> Major components of the mining operation are listed below. <br /> Ventilation Shaft New Roadway(between Cross and Caribou Mines <br /> Ventilation Shaft and Escapeway Roadway Accessing Caribou 300 Level <br /> Cross Mine Portal Caribou Management Office Trailer <br /> Idaho Tunnel Portal Caribou Storage Container 1* <br /> Caribou 300 Level Portal Caribou Storage Container 2* <br /> 2 <br />
