EXHIBIT L RECLAMATION COSTS <br /> The Lockhart Pit will have a bond to cover the worst-case reclamation scenario. Prior to opening <br /> the first proposed pod. The worst-case reclamation scenario will occur at the end of mine life <br /> when the West Pod requires final reclamation. Concurrent reclamation means that the East Pod <br /> will be reclaimed and that only the last 10 acres of disturbance and final high wall need <br /> reclaiming in the West Pod. <br /> Reclamation at this stage will include backfilling and grading the final mine slopes. Final <br /> topsoiling and vegetation planting will be required on the final 10 acres of the West Pod. As the <br /> operation will not contain any processing area or facilities, no structures will need to be <br /> removed. <br /> A detailed breakdown of the reclamation cost is shown in Table L-1. <br /> Table L-1 East Pod Reclamation Bond Calculation <br /> Description Material Unit Unit Cost Cost <br /> Quantity <br /> West Pod highwall backfilling and 12,000 CY $1.50 $18,000 <br /> grading. <br /> Topsoiling and grading 12 inches deep 16,133 CY $1.50 $24,200 <br /> the disturbed area of 10 acres total. _ <br /> Discing of topsoil to a depth of 12 inches 10 acres $250 $2,500 <br /> over 10 acres. <br /> Seeding of 10 acre disturbance area. 10 acres $325 $3,250 <br /> Assume a 25%failure rate via the unit <br /> cost. <br /> Mulching and crimping of mulch over 10 10 acres $1000 $10,000 <br /> acre disturbance area <br /> Weed control management for two years.
