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