Previous and current flow rates and field parameters at DP Spring are summarized in <br />Section 4. <br />PR Spring <br />The flow and field parameters were measured at PR Spring on May 24, 2011. The flow <br />at PR Spring was estimated by determining the time required to fill a 5- gallon bucket. <br />Field parameters from PR Spring were measured in the stock tank located at the spring. <br />The flow rate and field parameters at PR Spring are consistent with historical records. <br />The oxidation - reduction potential was relatively low, similar to what was observed at DP <br />Spring. <br />Previous and current flow rates and field parameters at PR Spring are summarized in <br />Section 5. Historical analytical data from PR Spring is summarized in Table 2. <br />Monitorins 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 measured for the static groundwater level and field parameters <br />and sampled on May 24, 2011. The water level, field parameters and analytical <br />constituent concentrations at Monitoring Well W -1 were similar to previous measurement <br />events. <br />Historical water levels and field parameters are summarized in Section 6. Historical <br />analytical data from Monitoring Well W -1 is summarized in Table 3. <br />Lumsden Canyon Seep <br />The Lumsden Canyon Seep (also referred to in earlier reports as Lumsden Canyon <br />Spring) was monitored for field parameters and sampled in June and December of 2008. <br />This location was monitored by Western Water & Land, Inc. during hydrologic <br />reconnaissance required by BLM stipulations to the mine permit. <br />The field parameters are summarized in Section 7 and the analytical data from the <br />Lumsden Canyon Seep samples is summarized in Table 4. No further sampling or field <br />parameter measurement events are scheduled at this time. <br />Rajah 49 Thornton Portal <br />Water was observed flowing from the Rajah 49 Thornton Portal and sampled on May 24, <br />2011. The flow rate was negligible (i.e., less than 1 gpm) and could not be measured. <br />Field parameters were measured and a sample collected for analysis. Field parameters <br />and analytical constituent concentrations at the Thornton Portal were similar to previous <br />measurement events. Field parameter measurements are included in Section 8 of this <br />report and the analytical data is summarized in Table 5. Energy Fuels will continue to <br />include the Thornton Portal in future annual seep surveys and collect samples for analysis <br />if discharge is observed. <br />Waste Rock <br />No ore was mined and no waste rock was produced in the First Quarter 2011. Because <br />the Whirlwind Mine is currently on stand -by status with only maintenance activities <br />being conducted, Energy Fuels has suspended the quarterly waste rock sample collection <br />2 <br />
