ENERGY FUELS RESOURCES <br />CORPORATION <br />To: Bruce Fowler September 21, 2007 <br />Grand Junction Field Office, BLM <br />2815 H Road <br />Grand Junction, Colorado 81506 <br />Re: Completion of Reclamation for Prospecting NOI <br />Whirlwind Claims, Mesa County, Colorado <br />Mr. Fowler: <br />Energy Fuels Resources Corporation (EFRC) has completed the drilling and reclamation of the <br />fourteen (14} holes described in the NOI submitted to you May 16, 2007, which is Colorado <br />DRMS permit number P-2007-019. The holes were plugged in accordance with the stipulations <br />you specified in your July 13, 20071etter. Surface reclamation was completed September 6, <br />2007. Seeding was also completed on that date. The tags from the seed mixture used are <br />attached. Seed was broadcast at a rate greater than 201bs/acre. <br />Abandonment Report <br />A. The fourteen holes were plugged by baclcfilling with cuttings through the portion of the <br />Salt Wash Member of the Morrison Formation that was penetrated. A plug of bentonite <br />pellets was installed to isolate the small amount of perched groundwater in the lower <br />sandstone of the Brushy Basin Member of the Morrison and prevent it from migrating <br />down the hole into the Salt Wash sandstones, which are dry. More cuttings were placed <br />in the holes, then a second bentonite plug was placed at the base on the Burro Canyon <br />Formation to prevent any potential groundwater in that sandstone from descending the <br />hole. Cuttings were placed above the second bentonite layer to near surface, then <br />plugged with at least 5 feet of concrete. A diagram of each hole is attached as Appendix <br />A. <br />B. Only small amounts of ground water were encountered in the holes. The potential for <br />perched water tables exist a# the base of the Burro Canyon Formation and in some <br />lenticular sandstones in the Brushy Basin. A nearby ground water test hole was drilled <br />by Umetco in 2000, for which BLM has the data. It shows the ore-bearing sandstone of <br />the Salt Wash to be dry. This is true of the entire area as can be seen in the numerous <br />mines down dip in the Salt Wash. <br />These exploration holes were drilled using compressed air for cuttings removal. If wet <br />zones are encountered, the large volume and high pressure of the drilling air tends to dry <br />limited inflow. Damp zones on the wall of the hole will catch the dry cuttings from the <br />E.ner~~p Pixels l~eso~irces C:c~r~araticm 31525 Road 9() P.O. L3ox li8$ <br />Nurla.
