EXHIBIT L <br />Reclamation Cost Estimate <br />In order to calculate maximum potential reclamation liability to the State, we have selected a <br />point in time where the mining disturbance could be at its maximum. At this time, the interior <br />mining face will be at its greatest length. There will be shoreline (exterior wall) under <br />reclamation in Phases 1 through 5. Please refer to Exhibit D for a listing of disturbed areas that <br />total 37 acres. This estimate will follow the same order as the listing in Exhibit D. <br /> Unit Cost Cost <br />Aspect Reclamation Operation Quantity Units ($) ($ <br />A.
