6.4.4(a) <br /> The majority of this site, including Phase 1 and Phase 2, will be mined using drill and blast <br /> techniques. In general, each new mining phase will be mined by first excavating vegetation and <br /> 0-24 inches of decomposed plant material and sandy loam with front-end loaders, excavators, <br /> and bulldozers from the first horizontal bench. <br /> After forest litter and sandy loam surface horizons are removed, the underlying metamorphic <br /> bedrock and previously exposed cliff faces will be drilled and blasted to a specified rough sized <br /> product(an average size of 3-foot minus), transported to the onsite processing area, processed, <br /> and sorted. Each subsequent bench will be stripped just in time to create the new working bench. <br /> The initial processing area will be created by filling the drainage southeast and adjacent to the <br /> mine site entrance south of the CCP. Fill will be composed of initial stripped material from the <br /> start of Phase 1 mining. The processing area will include a crushing and screening plant, material <br /> stockpiling, fuel tanks, truck scales, main office, and related structures. At the crushing and <br /> screening plant, various sizes of product will be created and sorted into separate stockpiles. <br /> Mining will occur in three or five phases dependent on the final post-mine land use (Table D-1). <br /> Phases will begin with initial mining and the creation of the site processing area as Phase 1, <br /> followed by mining Phase 2 to elevation 7850' —the west extent of the quarry and development <br /> of the potential road cut, and mining Phase 3 to elevation 7850' —the east extent of the site <br /> which further develops the Phase 1 area. If a reservoir is chosen for the post-mine land use, <br /> Phase 4 will mine the floor of Phase 2 down to 7535' elevation. Phase 5 will mine the floor of <br /> Phase 3 down to 7515' elevation in the reservoir post-mine land use option. Map C-2 shows the <br /> initial mining plan with projected phasing to the 7850' level and Maps F-1 and F-2 feature the <br /> Reclamation plan. <br /> Young Ranch Resource X Grey 1arnkki and Avv iatm PLLC <br /> February 2020 D-4 <br />
