EXHIBIT L <br />RECLAMAT ION COSTS <br />Financial warranty will be provided under CRS 1973, Section 34-32- <br />117(3)(a}(VTI), one of the self-insurance statutes. <br />Mining occurs from the north to south on the eastern half of the property and <br />occurs from the south to north on the western half of the property. ~ <br />. Reclamation costs are set on the <br />assumption that the ~ergest-a~ex3~e€disturbed area ~sEwiH~ex3sE increases for several <br />yeazs and then remains reasonably constant during the remaining life of the mine wi8-be <br />~eFeeAEetl-evE. As the pits advance, the mined areas are backfilled, graded, topsoiled <br />and seeded. Using these assumptions, maximum disturbance areas for these two pkeses <br />areas aze calculated as follows: <br />Area <br />Pit Disturbance <br />3 East''/z <br />3 West '/z <br />SUBTOTAL <br />Ancillary Disturbance <br />SUBTOTAL <br />Number of Acres +/- <br />Slope Floor Revegetation <br />36:33 5.9 <br />X63 12.4 <br />4334 18.3 <br />~61I8 3.3 <br />8~ 8.6 <br />3~b 11.9 <br />4736 9.2 <br />399 21.0 <br />64.E 30.2 <br />TOTAL DISTURBANCE <br />98.5 98.5 <br />.Since backfill will be continuous with the mining <br />operation es~; approximately . <br />341,400 cubic yazds of backfill will be required to return <br />the land contours to slopes capable of being traversed by farm machinery with no slopes <br />steeper than 2:1. Soils and spoils respreading, as well as all vegetation procedures, will <br />be required on _ <br />98.5 +/- acres. <br />Our estimate of costs for the various reclamation items are as follows: <br />50 Revised: Dec. 2003 <br />Total <br />4~-3A 9.2 <br />34•A9 21.0 <br />64s'i9 30.2 <br />68.3 68.3 <br /> <br />
