5. Reclamation Cost Estimate <br />Reclamation cost is calculated based on the worst case reclamation scenario. Usually the worst <br />case reclamation is at the end of mine life. However, in the case of this operation a comparison <br />of the costs of both the end of mine life and the current pit conditions is necessary due to the <br />current pit conditions. Costs for each reclamation scenario have been calculated for comparison. <br />The costs for the end of mine life are in the End of Mine Life Reclamation Cost Table. End of <br />mine life reclamation would consist of large scale pit dewatering, pit slope backfilling, <br />topsoiling, and revegatation. <br />End of Mine Life Reclamation Cost Table <br />Item Description Cost <br />1 Dewaterin of entire it 118.88 acre-ft $58/acre-ft $ 6,895.01 <br /> <br />2 Backfilling slopes of phase 4 (31-1:1 V to 10' below water line, then 2H:1 V) 74,485 CY <br />$1.10/CY <br />$ 81,933.50 <br />3 To soilin slopes to a depth of 8" in phase 4 45,281 CT $1.10/CY $ 49,809.34 <br />9 Backfill sediment and $1,397 CY $1.10/CY $ 1,536.70 <br />5 Seeding wetland vegetation 25.7 acres $1100/acre $ 28,270.00 <br />6 Seeding d land vegetation 7.0 acres $800/acre $ 5,600.00 <br /> <br />7 Lake discharege drainage ditch and river bank armoring (Seed: 0.1 acres @ $1500/acre, <br />Grouting: 6.75 CY @ $150/CY, Rock: 6.75 @ $12/CY, and Grading: $500) <br />$ 1,683.50 <br />Subtotal $ 175,728.05 <br />I DRIVIS overhead (21% of cost $ 36,902.89 <br />Total $ 212,630.94 <br />Tri County Technical Revision Sept 07 10
