Gold Eagle Mining Inc. Ellison Mine Permit Number M- 1978 -342 6.0 Designated Chemical(s) and Material(s) Handling At the present time there are no designated chemicals within the Ellison Mine permit area. Because the Ellison Mine has produced both Uranium and Vanadium ore the mine falls under the DMRS designation for a Designated Mining Operation. The materials that qualify for this special consideration are limited to uranium ore, waste rock, and potential leachate from these two materials because the use of designated chemicals is not planned for the Ellison Mine operation and the mineralogy and geochemistry of the host rock and ore indicates that acid -mine drainage will not occur. Testing of mineralized rock for uranium recovery or for environmental release considerations is currently disallowed due to the DOE limitation on activities on the lease. 7.0 Facilities Evaluation At the present time the only facilities at the Ellison Mine are a metal shop building and the mine portal. Given the probation on activity by DOE; no planning for future facilities at this site has been completed. The uncertain nature of the pending DOE PEIS limits the understanding of measures that will be necessary to limit impacts from ore and waste rock piles, air quality, and surface water facilities. Information from the DOE PEIS will guide the development of facilities and the Ellison Mine Site. 8.0 Groundwater Information The Ellison Mine site is located on a terrace on the south side of Burro Canyon which bisects the northwest flank of the Dolores Anticline. Mesozoic age continental sandstone, shale and mudstone are exposed by the incision of the canyon. Geologic units dip at a shallow 2 to 5 degrees towards the northeast. Exposed formations of Mesozoic age within one mile of the Ellison Mine (from bottom up) include the Jurrassic Period - Navajo Sandstone ( -200 ft. thick), Entrada Sandstone («70 to 90 ft. thick), Wanakah Formation also know as the Summervile Formation ( -100 ft. thick), and the Morrison Formation Salt Wash Member ( -300 ft. thick) and the Morrison Formation Brushy Basin Member ( -500 ft. thick); overlying the Jurrassic Period units is Cretaceous Period —Burro Canyon Formation ( -200 ft. thick). A generalized stratigraphic section is included as Figure 2 and a geological map of the area as Figure 3. The Ellison Mine site is in a geologically stable area, with the nearest fault zone of significance lying over 2 1 /2 miles to the west along the northwestern nose of the Dolores Anticline. The regularity of the northeasterly dendritic drainage on the northeast side of the Dolores Anticline (northeast of the Ellison Mine portal) is substantial evidence of the stability of the Ellison Mine site.
