DP Spring The field parameters were measured at DP Spring on June 4, 2013. The flow is measured by timing the fill rate of a five- gallon bucket. Field parameters from DP Spring were measured in the stock tank located at the spring. The field parameters at DP Spring are consistent with historical records. Flow rates and field parameters at DP Spring are summarized in Appendix 1, Attachment 4. PR Spring The field parameters were measured at PR Spring on June 4, 2013. The flow is measured by timing the fill rate of a five- gallon bucket. Field parameters from PR Spring were measured in the stock tank located at the spring. The field parameters at PR Spring are consistent with historical records. Flow rates and field parameters at PR Spring are summarized in Appendix 1, Attachment 5. Results from the annual sampling event, along with the historical analytical data from PR Spring are summarized in Appendix 2, Table 2. Monitoring Well W -1 Monitoring Well W -1 was installed on October 12, 2008 for the purpose of characterizing and monitoring groundwater quality downgradient of the waste rock storage area. Monitoring Well W -1 was measured for the static groundwater level on June 17, 2013. The water level at Monitoring Well MW -1 is consistent with previous measurements. Water levels and field parameters are summarized in Appendix 1, Attachment 6. Results from the annual sampling event, along with the historical analytical data from Monitoring Well MW -1 are summarized in Appendix 2, Table 3. Lumsden Canyon Seep The Lumsden Canyon Seep (also referred to in earlier reports as Lumsden Canyon Spring) was monitored for field parameters and sampled in June and December of 2008. This location was monitored by Western Water & Land, Inc. during hydrologic reconnaissance required by BLM stipulations to the Plan of Operations. No further sampling or field parameter measurement events are scheduled at this time. The field parameters are summarized in Appendix 1, Attachment 7 and the analytical data from the Lumsden Canyon Seep samples are summarized in Appendix 2, Table 4. Rajah 49 Thornton Portal (Raiah Spring) During the Survey, water was observed flowing from the Rajah 49 Thornton Portal (Rajah Spring). The Rajah Spring has been sampled in 2009, 2010, 2011, 2012, and 2013. Field parameters and a sample were collected on June 17, 2013. The estimated flow rate and measured field parameters are included in Appendix 1, Attachment 8 of this report and the analytical data is summarized in Appendix 2, Table 5. Energy Fuels will continue to include the Rajah Spring in future annual seep surveys and collect samples for analysis if discharge is observed. The field notes and photo log from the Survey are included as Appendix 3 of this report. K
