Waste rock pile <br />b. Ore stockpile <br />c. Soil excavation and stockpile areas <br />d. Surface drainage control structures <br />e. Fuel and oil storage areas <br />f. Shop /dry and maintenance shops <br />g. Roads and associated pads <br />h. Utilities <br />i. Ventilations shafts <br />a. Waste Rock Pile <br />The proposed waste area will be located on the western most slope of the <br />permitted area on top of the previously reclaimed mine waste area. The slope <br />here is quite steep so it will be terraced into two narrow benches, one above the <br />other (see Exhibit C labeled "waste rock pile "). Currently there is little to no <br />topsoil here so there will be no need to strip this area before dumping begins. As <br />stopes become mined -out, as much waste rock as possible will be gobbed in the <br />mined -out stopes. Thus, it is expected that the surface storage area will be <br />sufficient for all future mining operations and there will be no need for expansion <br />of the waste rock pile. The pile will be stacked to a height that will not impede <br />grading of 2:1 during reclamation. <br />Berms and ditches will be constructed around the waste rock pile to divert <br />stormwater away from the waste pile. A runoff basin will be constructed <br />downhill and adjacent to the waste rock pile to catch any surface runoff coming <br />off the piles (see Appendix II for a complete description of the Drainage Design <br />Plan). <br />C -4 <br />
