• Reclamation Costs Exhibit L <br />is <br />• <br />The worst case bond scenario will occur at the end of mine life. The road on the perimeter used for <br />access to the pit will remain in place in order to allow access after the site has been reclaimed. There <br />are no foundations or other structures which will be required to be removed with the reclamation <br />process. At this point, the wetland shelf elevations adjusted to match the equilibrium lake surface <br />elevation, the pit pump pulled, and topsoiling and seeding will need to be completed. Additionally the <br />staging area would have to be reclaimed. All areas above the static water table and outside of the <br />wetland footprint will have to be ripped, retopsoiled, harrowed and graded, and finally seeded. <br />A breakdown of all costs associated can be seen in the table below: <br />Table L-1 <br />Task # Description Time (days) Cost <br />1 Dewatering of pit (882.99 acre-fl $58/acre-ft) 80 $51,213 <br />2 Construct wetland shelf in Phase 4 (294,224 CY $0.65/CY) 5 $191,246 <br /> <br />5 Spread topsoil on wetland shelf using a D-8 w/universal blade. 19.37 acres <br />12 inches average thickness (31,250 CY $0.35/CY) <br />5 <br />$10,938 <br /> <br />6 Rip to a depth of 2.0 feet all areas to be topsoiled prior to topsoiling.
