Mining of each area will take place in the following steps: <br /> 1. Removal and stockpiling of topsoil and overburden. <br /> 2. Mining of placer gold-bearing gravel to bedrock. Dewatering of the active area, if <br /> needed,will pump water into a temporary settling basin adjacent to the active pit. <br /> 3. Transition toward the next area by removal and stockpiling of topsoil and overburden. <br /> 4. Begin backfilling of the previous area and begin reclamation. <br /> 5. Active mining can begin in the next area as topsoil and overburden are removed. <br /> Repetition of the above outlined general area mining procedure allows mining and reclamation to <br /> occur concurrently effectively minimizing disturbed ground on-site and the size of the <br /> reclamation bond. Furthermore, by directly replacing overburden from the future mining area to <br /> the recent and finished mining area, overburden on-site is conserved via a short distance of <br /> transport and limited exposure to the elements. <br /> The processing building will remain after reclamation as a horse barn for the residents of the site, <br /> in conjunction with the approved residential land use of this area. <br /> Three components of a portable gravel processing plant(crushing, screening, and washing)will <br /> be located somewhere in the gold mining area. Due to the plants portable nature, they may be <br /> located at various locations within the gravel pit area. Approximately 8-9 acres will be used for <br /> plants as well as stockpile areas. These areas are in addition to the stockpiles designated for the <br /> fixed gold plant described above. <br /> Used asphalt pavement and concrete rubble may be stockpiled on-site to be used in future <br /> crushing and stockpiling for use as a recycled material in new construction. Occasionally, soil <br /> that is determined to be free of debris and is inert may be brought on-site and stockpiled for use <br /> during reclamation. <br /> Mine access will be via Colorado State Highway 9—Main Street accessed from U.S. Highway <br /> 285 to the south or from Breckenridge along Hwy 9 to the north. <br /> The maximum disturbance is discussed in Exhibit L. The expected mining life is discussed <br /> below. <br /> Alma Placer Mine trek+ »Ar And Asuxwtm YIAX <br /> December 2017 D-5 �� <br />
