• <br /> • <br /> SSR <br /> MINING <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:1V. <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 2.5H:1V slope criterion for all backfill materials. New backfill slopes <br /> will be graded at an overall 2.5H:1V for reclaimed areas. If future plans indicate a steeper slope <br /> is more beneficial for habitat creation in some areas, a revision will be submitted to the Division <br /> of Reclamation, Mining and Safety 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 <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 2.2 discusses <br /> that at least 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 2.4. <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 2.5H:1V 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 eastern portion of the Globe Hill mine area. The final configuration <br /> of the area will remain as presented in MLE2 approved under Amendment 10. The South Cresson <br /> mine area will be backfilled as presented in TR142. <br /> • Cripple Creek&Victor Gold Mining Company Exhibit E <br /> Cresson Project Amendment 14 <br /> 12 <br />
