1 <br />1 <br />1 <br />1 <br />Historical field parameters are summarized in Appendix 1, Attachment 7 and the historical <br />analytical data from the Lumsden Canyon Seep samples are summarized in Appendix 2, Table 4. <br />Raiah 49 Thornton Portal (Raiah Suring) <br />The Rajah Spring has been sampled annually from 2009 to 2015. Field parameters and a sample <br />were collected on August 5, 2015 during the 2015 Seeps and Springs Survey. The Annual Seeps <br />and Springs Survey notes and photo log are included in Appendix 4. The analytical laboratory <br />data is provided in Appendix 5. EFRI will continue to include the Rajah Spring in future annual <br />seeps and springs surveys. <br />The estimated flow rate and measured field parameters are included in Appendix 1, Attachment <br />8 of this report, and the analytical data is summarized in Appendix 2, Table 5. <br />Waste Rock <br />' No ore was mined and no waste rock was produced in the third quarter 2015. The Mine is <br />currently in temporary cessation status with only maintenance and monitoring activities being <br />conducted. EFRI has suspended the quarterly waste rock sample collection until such time that <br />' mining operations resume and waste rock removal from the Mine recommences. <br />Production rates of ore and waste rock are summarized in Appendix 1, Attachments 9 and 10, <br />respectively. Analytical data from previously collected waste rock samples are summarized in <br />Appendix 2, Table 6. <br />Sediment Pond <br />The sediment pond has been monitored since its construction in November 2008 in accordance <br />' with the Colorado Division of Reclamation, Mining, and Safety stipulations. Although storm <br />events and significant snow melt events have occurred, none have resulted in stormwater <br />discharge from the pond. As a result, no stormwater samples have been collected from the pond <br />' to date. EFRI will continue to monitor the sediment pond for discharge and will collect samples <br />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 be <br />' monitored for selenium upstream and downstream from the confluence of Lumsden Creek when <br />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 Dolores <br />River, and <br />' 3) Selenium levels have been in exceedance of the CDPS permit effluent limits in the past <br />two years. <br />3 <br />
