NEWMONT <br />GOLDCORP <br />Surface Mine Backfill Areas <br />Backfilling is anticipated to occur to the ground surface or higher in two mine areas: the North <br />Cresson mine area and the East Cresson mine area. The backfill information presented in this <br />discussion is based upon information available at the time of submittal of this document and actual <br />backfilling may vary according to economic and mining conditions, and other factors. Backfilled <br />areas will be reclaimed in much the same manner as the OSAs. Slopes on the backfill adjacent <br />to the surrounding undisturbed terrain will be graded to an overall slope of approximately 2.5H:1 V. <br />Discrete slopes may vary in steepness within this overall slope to generate irregular landforms for <br />wildlife habitat. Drawing F-1 and the financial warranty calculations have been conservatively <br />developed based on an overall 2.5HAV slope criterion for all backfill materials. Portions of the <br />Main Cresson backfill will need to be reclaimed at an approximate slope equivalent to the angle <br />of repose due to placement constraints; therefore perimeter fencing around the mine area will be <br />installed to barricade access to the steeper slopes. <br />Benches with varying widths, spacing, and grades may be developed along the slopes to control <br />erosion, facilitate access for reclamation, or provide sites for tree and shrub plantings. <br />Growth medium will be used to cover the overburden placed as backfill. Section 1.3.2 discusses <br />that roughly six inches of growth medium is expected to be available to cover the areas for <br />reclamation. The growth medium may be sampled to determine the need for additional soil <br />amendments. Vegetation will be established according to the revegetation procedures presented <br />in Section 1.3.3. <br />Portions of Main Cresson mine area are expected to be partially backfilled as shown on Drawings <br />C-4 and F-1. The backfill will be trucked and dumped in lifts of varying heights depending on the <br />location of haul roads in that portion of the mine area. The backfilled material will be placed at an <br />approximate 2HAV slope and is not expected to approach the elevation of the natural ground <br />surface. Where practicable and safe, this backfill will be graded and reclaimed. As stated above, <br />perimeter fencing around the mine areas will be installed to barricade access to these steeper <br />slopes. <br />No backfill will be placed in the northern portion of the South Cresson mine area or in the eastern <br />portion of the Globe Hill mine area. The final configuration of these areas will remain as presented <br />in MLE2 -Amendment 10. <br />The Schist Island and western portion of the Globe Hill mine areas will be backfilled to promote <br />free drainage of stormwater to the surrounding ground surface and to blend with the SGOSA, as <br />described in the SGOSA discussion above. <br />Cripple Creek & Victor Gold Mining Company Exhibit E <br />Cresson Project Amendment 13 <br />11 <br />
