Exhibit L Reclamation Costs <br /> The operation will have a bond to cover the worst-case reclamation scenario. The worst-case <br /> reclamation scenario is based on the maximum disturbance area and greatest quantity of material that <br /> will need to be moved. <br /> Reclamation at this stage will include the removal of 10,000 CY of material from the active mining area <br /> and transferred to the London Mine 110D for processing. This cost is based on haul truck costs for an <br /> average distance of 2.7 miles. Following that transport, 20 acres of ground will need final grading, <br /> topsoiling, and revegetation. Grading is assumed to consist of converting from 1.5H:1V slopes to 2H:1V <br /> for a 50 ft depth across 500 feet for a volume of 4,630 CY. Topsoiling will be placed at a depth of four <br /> inches over 20 acres. Vegetation will be planted over all 20-acres. Vegetation monitoring will be <br /> maintained for two years. As the operation will not contain any processing area or facilities, no <br /> structures will need to be 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 /> Haul active material off to the London Mine 10,000 CY $5.50 $55,000 <br /> 110D <br /> Final grading of active mining areas. 4630 CY $1.50 $6,945 <br /> Topsoil 20 acres to a depth of 4 inches. 1 10,756 CY $1.50 $16,134 <br /> Vegetate 20 acres.Assume 50%failure rate. 20 acres $450 $9,000 <br /> Revegetation for a 50%failure rate. 10 acres $450 $4,500 <br /> Two years of vegetation monitoring.
