This was a partial inspection of the Elk Creek and Sanborn Creek Mines conducted by Jim Stark of CDMG. The inspection was conducted on 22 June 2006. Tom Anderson of Oxbow accompanied me on the inspection. The mine was actively producing coal at the time of the inspection and the coal stockpile was full. The weather was warm and sunny and the ground was dry. On 20 July 2006 the Division approved Minor Revision 81, which approved the construction of a warehouse expansion and concrete pad and Minor Revision 82, which approved the realignment of a light-use road to several gob vent boreholes (approved in Technical Revision 54) on USFS lands. Roads: -The mine access road is a paved road. The road is well maintained and in good condition. -The east yard haul road was stable and well maintained at the time of the inspection. There were no rutting or erosional problems noted on the road. - The road to the Elk Creek portals and facilities area was stable and well maintained at the time of the inspection. No erosional problems were noted on the road. The operator was watering the road at the time of the inspection. -The haul road to the West Valley Fill was stable and well maintained at the time of the inspection. No erosional problems were noted on the road. - The back entrance to the mine from Highway 133 was stable at the time of the inspection. This road is primarily used to access the Sanborn Creek gob vent boreholes and the mine when a train is blocking the main entrance. Hydrologic Balance: - Pond B contained water approximately five feet below the emergency spillway at the time of the inspection but was not discharging (discharge is through a gated valve below the water level).

The emergency spillway was stable at the time of the inspection. - Pond D contained water approximately one foot below the discharge pipe and was not discharging at the time of the inspection.
