NEWMONT <br />GOLDCORP <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 />A portion of the Wildhorse Extension (WHEX) mine area will be backfilled as approved in TR -96. <br />Generally, the pit will be backfilled and sloped to allow stormwater drainage to the west towards <br />the Globe Hill pit. As described above. the Schist Island mine area will be backfilled to the target <br />design 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 />3.7.4 Remining Overburden Storage Areas <br />CC&V submitted TR -104 to DRMS on August 23, 2018 to permit remining and processing <br />minerals waste material. This process was approved and will continue as part of this Amendment <br />13. <br />3.8 Haul and Access Roads <br />Public roads, haul roads and light vehicle access roads are routinely used to access the Cresson <br />Project facilities. These roads are shown on various Exhibit C drawings and are described below. <br />Public travel on the CC&V private roads is prohibited during mine operation and reclamation <br />activities unless necessary and only under appropriate CC&V supervision. <br />Dust will be controlled on roads as necessary with periodic watering. Dust control measures may <br />also include magnesium chloride surfactant or other suitable dust suppressants, mixed with other <br />suitable remedies to control dust as necessary. <br />Cripple Creek & Victor Gold Mining Company <br />Cresson Project Amendment 13 <br />16 <br />Exhibit D <br />
