mining conditions, and other factors, over the life of the Cresson Project. These <br />backfilled areas will be reclaimed in much the same manner as the OSAs. Slopes on the <br />backfill adjacent to the surrounding undisturbed terrain will be graded to an overall slope <br />of approximately 2.5H:1V. Discrete slopes may vary in steepness within this overall <br />slope to generate irregular landforms for wildlife habitate. Drawing F -1 and the financial <br />warranty calculations have been conservatively developed based on an overall 2.5H:1V <br />slope criterion for all backfill materials. Portions of the Main Cresson backfill will need <br />to be graded and reclaimed at an approximate 2H:1V slope due to placement constraints. <br />Benches with varying widths, spacing, and grades may be developed along the slopes to <br />control erosion, facilitate access for reclamation, or provide sites for tree and shrub <br />plantings. <br />Growth medium will be used to cover the overburden placed as backfill. Section 12.2 <br />discusses that about six inches of growth medium is expected to be available to cover the <br />areas for reclamation. The growth medium may be sampled to determine the need for <br />additional soil amendments. Vegetation will be established according to the revegetation <br />procedures presented in Section 12.3. <br />Portions of Main Cresson Mine area are expected to be partially backfilled as shown on <br />Drawings C -4, C -5 and F -1. The backfill will be truck dumped in lifts of varying heights <br />depending on the location of haul roads in that portion of the mine area. The backfilled <br />material will be placed at an approximate 2H:1V slope and is not expected to approach <br />close to the elevation of the natural ground surface. Where practical and safe to do so, <br />this backfill will be graded and reclaimed. Portions of the Main Cresson Mine area <br />backfill will be graded and reclaimed at an approximate 2H:1V slope due to placement <br />constraints. <br />No backfill will be placed in the northern portion of the South Cresson portion of Main <br />Cresson Mine area or in the eastern portion of the Globe Hill portion of the North <br />Cresson Mine area. The final configuration of these areas will remain as defined by <br />Cresson Project development. Growth medium will be redistributed on flat benches and <br />to a limited extent on the un- backfilled bottom portions of the mine areas to a depth of <br />approximately six inches or less depending on accessibility. <br />Cripple Creek & Victor Gold Mining Company <br />Cresson Project Mine Life Extension 2 <br />12 -13 <br />
