NEWMONT <br /> GOLDCORR <br /> discussed in previous plans. Backfill configurations and sequencing for VLF2 Phase 3 during mine <br /> operations are presented in the Valley Leach Facility 2 Phase 3 Detailed Design Report, included <br /> in Appendix 1. Backfill configurations and sequencing for other mine areas are provided in <br /> previous amendments and plans. Note that the actual amount of backfill and the timing of <br /> backfilling activities for a mine area and a particular year may change based on project economics <br /> and may vary from what is shown on these permit drawings. Backfill configurations for reclamation <br /> are shown on drawings presented in Exhibit F. <br /> Once condemnation sampling is performed and a surface mine area is deemed complete, these <br /> mine areas will become available for backfill of overburden. Overburden backfilling will occur in <br /> the Main Cresson, East Cresson and North Cresson (including the Schist Island) mine areas. The <br /> extent of backfilling in these areas is dependent on mine-sequencing and material availability. <br /> Existing OSAs may be utilized as a resource depending on changing economic circumstances <br /> (as approved by TR-104), which would create additional capacity in existing OSAs for overburden <br /> deposition. Backfill and grading activities are discussed below. <br /> Backfill and Grading Activities <br /> Backfilling will be accomplished by truck placement of the overburden material in "lifts" that vary <br /> in height, depending on the logistics of truck hauling, the geographic locations relative to the mine <br /> areas, and overburden removal scheduling. Drawing F-1 shows the post-mining topography for <br /> backfilled mine areas and is provided in Exhibit F. <br /> Backfill will be placed generally to the grades and elevations shown in Exhibit F. Backfill will be <br /> graded to provide positive surface water flow and will be blended with the surrounding topography. <br /> Newly created backfill of the Main Cresson will be graded to a 2.5H:1 V or flatter. Differing areas <br /> of 2H:1 V slopes will be oriented against the highwalls to blend the topography. A portion of the <br /> Wildhorse Extension (WHEX) mine area will be backfilled as approved in TR-96. Generally, the <br /> pit will be backfilled and sloped to allow stormwater drainage to the west towards the Globe Hill <br /> pit. As described above, the Schist Island mine area will be backfilled to the target design <br /> elevation, 10,650 ft, for VLF2 Phase 3. <br /> The main portion of WHEX and western portion of the Globe Hill mine areas will be regraded to <br /> promote free drainage of stormwater runoff from these areas at closure. Backfill will result in only <br /> a partial end-dumped backfill of the Main Cresson mine area. <br /> The backfilled North Cresson and East Cresson mine areas will be graded to be free draining for <br /> surface water. Drainage will be directed to one of several Enhanced Management Ponds (EMPs). <br /> Cripple Creek&Victor Gold Mining Company Exhibit D <br /> Cresson Project Amendment 13 <br /> 16 <br />
