RECLAMATION COST ESTIMATE <br />The following Reclamation Cost estimate is based on the <br />assumption that there will be no more than 9.16 acres ± disturbance <br />at any one time. The mine working face will be 400 feet long by 20 <br />feet high and that when it comes time to resoil the area, an aver- <br />age of 8 inches of soil would be spread over the disturbed area. <br />At that time we will have to respread 9,852 cubic yards of topsoil <br />and move 1,852 cy of cut\fill sloping. There will be 50 feet of <br />backfilling and shaping on the exterior slopes needing 926 cubic <br />yards. The table below outlines the various areas of disturbance <br />at the time explained above. A D8N is used to do the shaping and <br />resoiling in this calculation and the mobilization haul distance is <br />9.25 miles. The revegetation cost figure used includes fertilizer, <br />grass seed, labor and drilling costs. <br />STAGE <br />NEEDING REBOILING <br />REVEGETATION AREA <br />REBOIL @ 1 0° <br />GUT/FILL SLOPING <br />BACKFILL SLOPING <br />TOTAL SOIL DEPTH <br />9.16 8 <br />9.99 <br />9,852 CUBIC YARDS <br />1,852 CUBIC YARDS <br />926 CUBIC YARDS <br />EST/MATED UNIT COSTS FOR RECLAMAT/ON ITEMS. <br />Unit Cost <br />1.
