Characterization of mine water in the Packrat Mine could not be conducted because the <br />mine is not yet accessible. Section 3 of the Hydrological Report is reserved for field data <br />collected from the Packrat Mine at such time that is becomes accessible and is monitored. <br />DP Spring <br />The flow and field parameters were measured at DP Spring on June 2, 2010. The flow <br />was estimated by determining the time required to fill a 5-gallon bucket. Field <br />parameters from DP Spring were measured in the stock tank located at the spring. The <br />flow rate and field parameters at DP Spring are consistent with historical records. <br />However, it has been noted that the dissolved oxygen levels at DP Spring have been <br />slightly elevated over previous quarters since the Fourth Quarter 2009 measurement <br />event. <br />Previous and current flow rates and field parameters at DP Spring are summarized in <br />Section 4 of the Hydrological Report. <br />PR Spring <br />The flow and field parameters were measured and a sample was collected for analysis at <br />PR Spring on June 2, 2010. The flow at PR Spring was estimated by determining the <br />time required to fill a 5-gallon bucket. The flow rate was similar to that last observed in <br />December 2009 and about half that measured in previous sampling events in 2008 and <br />2009. During the sampling event, it was noted that large patches of vegetation, similar to <br />moss, were floating in the stock tank. The lid to the spring collection box (located <br />upstream of the stock tank) was removed and similar material was observed in the box, <br />partially blocking the discharge pipe to the stock tank. Excess water in the box is <br />directed to an overflow pipe that discharges on the ground adjacent to the stock tank. It is <br />suspected that the partial blockage is the cause of the lower flow rate observed during the <br />last two quarters. Energy Fuels plans to remove the material from the box and take flow <br />measurements after the flow has stabilized during the next quarterly measurement event. <br />Field parameters from PR Spring were measured in the stock tank located at the spring. <br />Field parameters were consistent with previous measurements with the exception of <br />dissolved oxygen which was lower than measured during previous events, 2.27 mg/L <br />down from an average of 8.86 mg/L. The lower dissolved oxygen levels may be related <br />to the observed vegetative material, discussed above. <br />Previous and current flow rates and field parameters at PR Spring are summarized in <br />Section 5 of the Hydrological Report. Analytical data from PR Spring is summarized in <br />Table 2. The analytical data report for the collected sample is included in Appendix A. <br />Monitoring Well W-1 <br />Monitoring Well W-1 was installed on October 12, 2008 for the purpose of characterizing <br />and monitoring groundwater quality downgradient of the waste rock storage area. <br />Monitoring Well W-1 was sampled on June 7, 2010. Baseline characterization sampling <br />was completed in the First Quarter 2010 and the June 7 sampling event is the first annual <br />sample collected from the well. The water level, field parameters and analytical data <br />from Monitoring Well W-1 were similar in chemistry and water quality to previous <br />sampling events. <br />2
