• on Drawings C-5 and F-l. The backfill will be truck dumped in lifts of varying <br />heights depending on the location of haul roads in that portion of the mine area. <br />The backfilled material will be placed at an approximate 2H:1 V slope and is not <br />expected to approach the elevation of the natural ground surface, but encompasses <br />significantly more of the mine area than the previously approved backfill under <br />Amendment No. 8. This backfill area will not be regraded or receive soil <br />placement and revegetation. <br />No backfill will be placed in the southern portion of Main Cresson Mine area (the <br />South Cresson portion) or in the Globe Hill portion of the North Cresson Mine <br />area. The final configuration of these areas will remain as defined by the mining <br />operation. Growth medium will be redistributed in the unbackfilled bottom <br />portions of the mine to a depth of approximately six inches or less depending on <br />accessibility and availability of material. <br />The Schist Island portion of the North Cresson Mine area will be backfilled to <br />promote free drainage to the surrounding ground surface, to cover highwalls that <br />remain followin mining activities and to blend with the SGOSA. As such, the <br />information provided above related to reclamation of SGOSA includes the <br />backfilled North Cresson Mine area. <br />• The East Cresson Mine area is expected to be backfilled to promote free drainage <br />to the surrounding natural ground surface as previously approved for Amendment <br />No. 8. This backfilling will include the WHEX portion of the East Cresson to be <br />mined as part of the MLE. Backfilling will be accomplished by end-dumping the <br />material in "lifts" that range in height, depending on the logistics of truck hauling, <br />the geographic locations relative to the mines, and overburden removal <br />scheduling. It is anticipated that this area will be backfilled to an elevation and <br />shape that will promote free drainage to the surrounding surface and graded to <br />blend with the surrounding topography including the reclaimed topography of the <br />ECOSA. Growth medium will be used to cover the overburden placed as backfill. <br />Section 11.2 discusses that approximately six inches of growth medium is <br />expected to be available to cover the reclamation areas. Other material containing <br />fines will be used if stockpiled growth medium is not available. The growth <br />medium will be sampled to determine the need for amendments. Vegetation will <br />be established according to the revegetation procedures presented in Section 11.3. <br />Cripple Creek & Victor Gold Mining Company <br />Cresson Project Mine Life Extension <br />11-13 <br />•
