RECLAMATION COSTS <br />1. Gold Operation <br />EXHIBIT L <br />Most of the gold mine disturbance will be reclaimed as mining continues and reclaims behind the <br />advancing cuts. The plan allows for one cut in some stage of stripping, another in the stage of <br />extracting gravel to send to the gold plant and another in some stage of reclamation. The worst case <br />reclamation scenazio occurs at the end of mining. At the end of gold mining, 22.9 acres will need to <br />be regraded requiring the movement of 59,800 cy. All buildings from the gold operation will be <br />removed, however, power poles and some roads will remain, as shown on Map F. In addition, 23.1 <br />acres will need to be retopsoiled and revegetated. However, this is not the worst case reclamation <br />scenario for the life of the mine. If the mining continues into cuts 3,4,and 5, while the previous cuts 1 <br />and 2 aze still in some stage of regrading and reclamation, this results in a total azea of 28.6 acres to <br />be reclaimed and an approximate volume of 78,000 cubic yazds for backfilling. <br />The tasks and costs for the worst case reclamation scenario aze given below: <br />Gold Operation Worst Case Reclamation Costs and Timetable <br />Task Description Time Needed Cost <br /># months <br />1 Remove Facilities, including gold 1.5 $9400 <br /> processing plant, fuel tanks, pump <br /> and piping, shop building, misc. <br />2 Regrade 24 of 28.6 acres of site using 3.0 $31200 <br /> Cat D-8 dozer (78,000 cy @ $0.40 per <br /> cy). This includes collection ditches, <br /> certain ponds, finz cu±s, camp areas, <br /> plant azea and shop azea. <br />Alma Placer 7/03 75 <br />
