THOMPSON PROPERTIES P.O. BOX 3 GRANBY, CO 80446 (970) 8873710 August 1, 2008 Mr. Tony Waldron Division of Reclamation, Mining & Safety Minerals Section RECEIVED 1313 Sherman Street Suite 215 Denver, Colorado 80203-2273 AUG 0 6 2008 Division of Reclamation, Dear Mr. Waldron: Mining and Safety Re Thompson Resource aka Horn Gravel Pit Permit No. M-1983-102, 2008 Annual Report Our files indicate that the anniversary date for this permit is August 2, 2008. This pit HAS NOT been granted a Temporary Cessation and it HAS operated more than 180 days this year. The Financial Warranty for this operation is $111,500.00, the permitted area is 70.12 ac.± and has a single Reclamation Phase. As required in Rule 1. 6 the MINE PERMIT SIGN is at the entrance to the pit and the boundary has been outlined with posts to delineate the Permit Boundary. Groundwater monitoring results are attached for the 3 monitoring wells installed in June 2007. This data is needed to establish a trend in ground water elevations for the site. It seems to fluctuate during the year based on the amount of irriga- tion that takes place on up gradient properties. Additional data is needed to complete a cycle and we do not plan to start mining in the next year in the new area, so additional data will be available prior to that time. From this we can show a trend that will let us establish the final floor elevation. The annual report requirements in the MLRB Rules and Regula- tions, and the annual review letter are addressed in the follow- ing report. Please refer to the 2008 ANNUAL REPORT MAP submitted with this text for the locations of the areas discussed. (1) Mining continued on area previously disturbed on the west side of the mine.
