Summary of Quarterly Hydrological Monitoring <br />Monitoring Activities <br />This report summarizes the quarterly monitoring activities at Energy Fuels Resources <br />Corporation's ( "Energy Fuels ") Whirlwind Mine (the "Mine "), as required by Attachment B of <br />the Bureau of Land Management's (the `BLM's ") Decision Record, Finding of No Significant <br />Impact, and Final Environmental Assessment for the Whirlwind Mine Uranium Mining Project <br />(the "EA "). The following field monitoring activities were performed during the third quarter <br />2013 (July through September 2013) at the Mine: <br />• Quarterly water level measurements and field parameters were taken at DP Spring, PR <br />Spring and at MW -1 on August 14, 2013. However, due to recent employee turnover, the <br />field notes containing the required measurements were lost. <br />Whirlwind Mine Treatment Plant <br />During periods when the treatment plant is in operation, mine water from the Mine is pumped to <br />the surface, stored in a water tank, treated and discharged to the middle tributary of Lumsden <br />Creek. Discharge of treated water from the Mine is allowed in accordance with Colorado <br />Discharge Permit System permit number CO- 0047562. <br />Energy Fuels has suspended use of the Mine water treatment plant until such time that mining <br />operations resume. No water has been pumped from the Mine since December 2009, and Mine <br />water has been allowed to accumulate in the Mine workings. Refer to Appendix 1, Attachment 1 <br />of this report for a summary of mine water treatment. <br />Whirlwind Mine and Packrat Mine <br />The inflow within the Mine decline cannot be measured directly because it occurs over <br />approximately 100 feet from the entrance of the decline and within the drifts. The water collects <br />in the mine sump, and is subsequently pumped into the untreated water tank on the surface when <br />the mine is operating. Currently inflow is calculated based on the approximate elevation level of <br />accumulated mine water, and the void volume of the workings. <br />Access to the Mine decline was restricted during the second quarter of 2012. As a result, flow <br />rate and field parameter measurements were also put on hold until such time that the Mine is <br />reopened. Historical flow rates and field parameters from the Mine decline water are included in <br />Appendix 1, Attachment 2. Analytical data from the previous samples collected from the Mine <br />are summarized in Appendix 2, Table 1. <br />Characterization of mine water in the Packrat Mine could not be conducted because the mine is <br />not yet accessible. Appendix 1, Attachment 3 of this report is reserved for field data collected <br />from the Packrat Mine at such time that it becomes accessible and is monitored. <br />1 <br />
