<br />RECLAMATION COSTS <br />• • EXHIBIT L <br />This reclamation cost estimate is base on the current condi- <br />tions that we feel are a worst case scenario. It is based on a <br />maximum area of disturbed of no more than 48.00 acres ± at any one <br />time. This includes areas stripped, partially mined and partially <br />reclaimed. We have based this on a interim reclamation proposal on <br />the nature of the operation, where there are large piles of pit run <br />gravel stripped off the clay vein as overburden, that will be <br />processed when mining progresses into the pile location. in this <br />scenario, mid term reclamation would entail mostly cut/fill grading <br />of stockpiled materials, recoiling four areas and grading the <br />disturbed areas to ready it for revegetation. The table below <br />outlines the baseline data we used in our bond estimate calcula- <br />tion. The disturbed area is confined to clay Stages 0 thru III, <br />and gravel Stages A & B. <br />DESCRIPTION TOTALS <br />AREA NEEDING REVEGETATION 47.00 ac. <br />SEEDBED GRADING/SHAPING 43.44 ac. <br />NEEDS RHSOILING 11.64 ec.
