EXHIBIT L <br />RECLAMATION COSTS rr.a. 7/sa- <br />These reclamation costs are based on the current conditions at <br />the mine. We are assuming this is when it will be most costly to <br />reclaim the mine because the cost to dewater verses revegetation <br />are beginning to offset each other. Our estimate includes areas <br />stripped, partially mined and partially reclaimed, lake surface <br />area does not need reclamation but will be pumped and bank sloping. <br />Please see the attached sheets for a graphic representation of the <br />areas needing reclamation work and how the cut/fill bank sloping <br />volumes were arrived at. The de-watering costs worksheet is <br />attached so you can see the methodology I used. The table below <br />outlines the baseline data we used to do our bond estimate <br />calculation. The areas in the table are all within the mined area <br />which does not include the setbacks. In addition, the disturbed <br />area is shown on the reclamation bond map attached. <br />DESCRIPTION TOTALS <br />AREA NEEDING REVEGETATION 37.51 ac. <br />LAKE AREA 72.67 ac. <br />NEEDS REBOILING 22.17 ac.
