• WATER INFORMATION EXHIBIT G <br />1. Introduction <br />Umetco Minerals Corporation (Umetco) and the U.S. Bureau of Land Management (BLM) extensively <br />monitored the ground and surface water in the project area in the 1990s and early 2000s as part of mine <br />closure and reclamation activities. Energy Fuels has conducted additional monitoring since acquiring <br />the mineral rights in fourth quarter 2006. Both the current and historic data have been compiled into <br />four tables (Tables E-1 through E-4), which are presented in Appendix E. State and federal regulatory <br />standards for various ground and surface water uses are listed at the bottom of each of these tables and <br />those analytical results that are above a standard are shaded for reference purposes. Shading indicates <br />that the water in question may not be suitable for one or more regulated uses such as domestic drinking <br />water. The laboratory reports and field information used in compiling the ground and surface water <br />quality tables are also provided in Appendix E. <br />• Much of the hydrogeologic background information presented in this exhibit was obtained from a <br />series of Umetco reports that were submitted to the State and BLM during the aforementioned closure <br />and reclamation period. Two of these reports have been included in their entirety as Appendix C. <br />Exploration activities conducted by Cotter in 1996 and by Energy Fuels in 2007 also provide insight <br />into the local geology and ground water systems. Reports describing the 1996 and 2007 drilling results <br />are provided in Appendix D. Supporting figures and maps referenced in this exhibit are included in <br />Appendix I, Maps and Figures. <br />2. General Area Discussion <br />The area where the mining will take place is known as Beaver Mesa. The regional area is characterized <br />by mesas cut by deep canyons. There are narrow benches on the mesa shoulders in some areas and <br />near-vertical, 500-foot cliffs elsewhere. Elevations within the claim group range from 7,800 feet in the <br />southwestern part to 6,800 feet near the canyon rim in the northeast part. The area is semiarid. All <br />elevations support moderate growths of juniper and piiion in rocky soils along with sage and other <br />• <br />Whirlwind Mine 07 (rev. April 08) G-1 <br />
