Waste Rock <br />No ore was mined and no waste rock was produced in the second quarter 2013. The <br />Mine is currently in temporary cessation status with only maintenance and monitoring <br />activities being conducted. Energy Fuels has suspended the quarterly waste rock sample <br />collection until such time that mining operations resume and waste rock removal from the <br />mine commences. <br />Production rates of ore and waste rock are summarized in Appendix 1, Attachments 9 and <br />10, respectively. Analytical data from previously collected waste rock samples are <br />summarized in Appendix 2, Table 6. <br />Sediment Pond <br />The sediment pond has been monitored since its construction in November 2008 in <br />accordance with the Colorado Division of Reclamation, Mining, and Safety stipulations. <br />Although storm events and significant snow melt events have occurred, none have <br />resulted in stormwater discharge from the pond. As a result, no stormwater samples have <br />been collected from the pond to date. Energy Fuels will continue to monitor the sediment <br />pond for discharge and will collect samples in the event that a discharge is observed. <br />Dolores River <br />In accordance with BLM stipulations to the mine permit, the Dolores River is required to <br />be monitored for selenium upstream and downstream from the confluence of Lumsden <br />Creek when all of the following conditions are met: <br />1) The Mine treatment plant is discharging treated water, <br />2) There is continuous flow from the middle tributary of Lumsden Creek to the <br />Dolores River, and <br />3) Selenium levels have been in exceedance of the CDPS permit effluent limits in <br />the past two years. <br />Because water treatment of mine water has been suspended, it was unnecessary to <br />monitor Lumsden Creek for discharge to the Dolores River in the second quarter 2013. <br />Energy Fuels will commence monitoring the Dolores River for discharge from Lumsden <br />Creek and take samples, as necessary, at such time that treatment and discharge of mine <br />water resumes. <br />Hydrological Monitoring Summary <br />Refer to Appendix 2, Table 7 for the hydrological compliance monitoring summary and <br />status for the Mine. <br />3 <br />
