DIVISION OF MINERALS AND GEOLOGY <br />Department of Natural Resources <br />1313 Sherman St., Room 215 <br />Denver, Colorado 80203 <br />Phone: (303) 866 -3567 <br />FAX: (303) 832 -8106 <br />July 7, 1999 <br />Mr. Roger Day <br />AmerAlia, Inc. <br />P.O. Box 1330 <br />Rifle, CO 81650 <br />RE: Reclamation Costs, Rock School Lease Experimental Nahcolite Mine Project, <br />File No. M -99 -051 <br />Dear Mr. Day: <br />Please find enclosed the preliminary reclamation cost estimate for the Rock School Lease Project. The cost <br />estimate is the basis for the amount of bond that will be required for permit issuance. Certain components <br />of the estimate will be updated once AmerAlia provides responses to the adequacy issues listed in the <br />Division's letter dated June 18, 1999. For example, costs will be included for the disposal of pond liners <br />and residues based on AmerAlia's responses. Costs for tree planting will also be included as appropriate. <br />One of the most significant reclamation costs included in the estimate is for demolition of surface structures. <br />Unit costs for building demolition are based on building volume, and the Division's estimate is based on <br />assumed heights for the buildings. If AmerAlia provides the actual heights proposed for each building, the <br />cost estimate may be refined. <br />If you have any questions, please contact me. <br />Sincerely, <br />Allen C.
