RECLAMATION COSTS <br />EXHIBIT L <br />The worst case reclamation costs occur when the mining is completed in Area 5 and final backfilling <br />is needed on the southern part of this area as well as topsoiling and seeding of the 10 acre facilities <br />area. Mining will commence on the northern part and progress south to keep the amount of <br />backfilling required at the end of mining to a minimum. By mining south the operation will connect <br />to the drained lake of Mining Area 3. As mining progresses to the south in Area 5, all the land <br />peninsulas will be built from the overburden ahead of the active pit. Therefore, at the end of mining, <br />backfilling and grading is limited to the lower two sides of the land peninsulas for a distance of 180 <br />feet to the north. This is an area of 1.4 acres. The detailed tasks are given below: <br />1) Backfilling the southern part of the pad area (approx 1.4 acres) for Area 5. Since the final land <br />surface is 4468' and the pit bottom is approximately 4433', the area will be filled 35' high. This is <br />79,000 cy. Material will come from a nearby pile in Area 5 left for this backfilling. <br />2) back£illing of slopes in the upper half of Area 5 lake to 3H:1 V based on 800 feet length and 578 <br />sq. ft x-section (from 2:1 to 3:1) = 17,000 cy. Material will come from a nearby pile in Area 5 left <br />for this backfilling, <br />3) topsoiling will be needed along all land areas of Area 5 as well as the final facilities area. This is a <br />total of 25.1 acres. As shown in the reclamation plan, placing 8" of soil on these areas requires <br />26,996 cy. The soil will be obtained from the two stockpiles shown on Map C-land from a <br />4) revegetation will be needed along all land areas of Area 5 as well as the final facilities area and <br />the two topsoil stockpile areas once the topsoil is removed. This is 32.1 acres. <br />15 Road Pit 10/02 45 <br />
