(Page 2) MINE ID # OR PROSPECTING ID # M-1994-113 INSPECTION DATE 5/19/04 INSPECTOR'S INITIALS RCO OBSERVATIONS This inspection was performed by the Division in response to the operator's request for an inspection to discuss upcoming changes, and as part of its monitoring of Construction Materials 112c permits. The operator's representative named on page one was present during the inspection. The site has not been actively excavated in a couple years, though stockpiled material continues to be removed regularly. The highwall is maintained in a graded and stable condition, and the cut above the haul road is maintained. Stripped topsoil has been stockpiled in several protected locations in the permit, the oldest piles have been adequately vegetated. There appears to be an adequate amount of topsoil to respread over the disturbed areas. Not all portions of the affected area have been disturbed. Several wooded slopes still remain undisturbed, with disturbance limited to the active excavation area, pit floor, processing and stockpile area, topsoil stockpile areas, and access roads. This helps keep the bond low, limits instability and minimizes need for maintenance. Two of the areas still undisturbed are the small wetland in the northern end of the permit, and an adjacent area covered by aspen trees. These lie immediately east of the existing haul road. Much of the haul road was built upon the hydroelectric penstock that crosses the permitted area. That specific section of the haul road alongside the wetland was built upon the weaker fiberglass portion of the penstock. Damage to the penstock was found several years goo, and it was repaired, but haul traffic was severely curtailed. The operator began exploring the option of rerouting that part of the haul road, specificallvto the area of the wetland. It was for purposes of discussing this chanoe that the operator contacted this office for an inspection. hundred feet long. The bond amount was reviewed and is felt to be adequate for now, since there has been no further disturbance since it was last recalculated. As part of the technical revision, this office will pertorm a thorough bond recalculation. No further items were observed during the inspection. Responses to this inspection report should be directed to the Division of Minerals and Geology, 701 Camino del Rio, Room 125, Durango, Colorado 81301, Attn: Bob Oswald; phone no.970-247-5193.

STREET PO Box 797 CITY/STATE/ZIP Telluride, CO 81435 cc: Harry Posey, DMG ^ CE ^ BL ^ FS ^ HW ^ HMWMD (CH) ^ SE ^ WOCD (CH) ^ OTHER The main excavation area daylights on the west to a deep creek. The edge of the floor is bermed, though the outslope itself is naturally loose and sloughing. The operator does not push material off the edge. The pit floor will be deepened considerably, as indicated by the visible boundary markers far down the slope. Though there is a berm at the top of the slope, there is a potential for rolling material moving down the slope. The operator should continue to maintain the silt fence that was installed there in past years.
