~~~ C077ER March 31, 2003 Division of Minerals and Geology Department of Natural Resources Attn: Glenda Williams 1313 Sherman Street, Room 215 Denver, CO 80203 Subject: C-CM-25 Mine Annual Report File No. M-1977-307 Dear Ms. Williams: RECEIVE® APR 0 8 1003 Division of Minerals and GealosY The C-CM-25 Mine is located in Montrose County and operates under a 110 permit, with a permitted acreage of 7.34 acres. This mine does not have a phased reclamation plan. In February, 2003, Cotter Corporation completed final reclamation of the CM-25 Mine. The method of reclamation was agreeable to D.O.E. and Umetco Minerals Corporation, the land owners of the affected areas. The reclamation work consisted of removing the extended timbered portal area (snow shed), contouring the dump, and backfilling the portal and portal cut area, which were located on Umetco property. The mine dump was contoured by excavating a portion of the dump material back up-slope. The excavated material was then used to backfill the portal and portal cut area, and contoured to blend in with the surrounding topography. The shop and compressor buildings were removed and the concrete slabs covered with at least two feet of topsoil. Two vent holes and a power drop hole, located on D.O.E. property, were closed using waste rock and polyurethane foam. All non- essential power poles and lines associated with the incoming power line were removed. Reclamation of two pre-law sites, the La Sal Shaft and the Mill No. 2 Portal, were reclaimed by backfilling them with waste material from nearby mine dumps. The mine dumps were then contoured to better blend in with the surrounding topography. Cotter Corporation - West Slope Operations Telephone 1970) 864-7347 P.O.
