EXHIBIT L RECLAMATION COSTS <br /> This reclamation cost estimate in based on the assumption that <br /> there will be no more than 40 . 00 acres ± needing resoiling and <br /> revegetation at any-one-time. No dewatering is needed since the <br /> underwater slopes are created as mining progresses by placing <br /> excess sand along the mined slopes or the working face could be <br /> done using a push in method. The following information portrays a <br /> time period consistent with what is shown on the Mining Plan map <br /> where Lake Robert and the north end of Lake Marjorie are reclaimed. <br /> The southern end of Lake Marjorie is used as a processing and <br /> stockpile area (8 . 0 ac) , and sand storage area. In the west area <br /> the West Lake has been partially stripped and mined. The north end <br /> is a Concrete Plant Site area. The East lake is actively being <br /> mined from north to south and has a 3 . 0 acres recycle area. The <br /> area around the lake and the recycle area would need reclamation <br /> and there is a 575 foot long working face that would need partial <br /> grading. The Asphalt Plant site area in Lake Marjorie and the <br /> Concrete Plant area on the north end of the West area would need no <br /> work as they will remain when mining ends . <br /> In this scenario, some material is still being mined in the <br /> existing pit area. The areas needing to be resoiled and seeded are <br /> the processing plant area and sand stockpile in Lake Marjorie; the <br /> stripped area on the north and south end of the West lake and the <br /> lake shores; and in the East Lake, the lake shores and stripped <br /> area. The roads, parking areas, Concrete and Asphalt Plant areas <br /> will need no work. The method used to revegetate the lake perimeter <br /> will remain as currently permitted. This is an attempt to set the <br /> bond so there is flexibility to operate without reevaluating the <br /> bond yearly. <br /> According to our scenario, we will have to respread 6 inches of <br /> topsoil on 40 . 0 acres or 32, 367 cubic yards of soil and revegetate <br /> 40 . 00 ac.±. The working face grading will need to move 57, 505 yds <br /> (575 ft @ 91 yd/lft) . Table L-1 - Bond Estimate, shows the total <br /> areas and volumes needed to complete .reclamation using these <br /> numbers . Our cost estimate is based on using a Cat 140M blade for <br /> seed bed preparation & ripping, a Cat 631B scraper for resoiling <br /> and a Cad D8T for cut/fill sloping, but the actual equipment used <br /> by the permittee may differ. The revegetation cost figure includes <br /> grass seed, mulch, chemical fertilizer (ammonium nitrate & <br /> superphosphate) drilling costs and mulch crimping. <br /> ESTIMATED UNIT COSTS FOR RECLAMATION ITEMS: <br /> Unit Cost <br /> 1 .
