r � <br /> Lumsden Cannon Seep <br /> The Lumsden Canyon Seep (also referred to in earlier reports as Lumsden Canyon Spring) was <br /> monitored for field parameters and sampled in June and December of 2008. This location was <br /> monitored by Western Water & Land, Inc. during hydrologic reconnaissance required by BLM <br /> stipulations to the Plan of Operations. No further sampling or field parameter measurement <br /> events are scheduled at this time. <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 /> Rajah 49 Thornton Portal (Rajah Spring) <br /> The Rajah Spring has been sampled annually from 2009 to 2018. Field parameters and a sample <br /> were collected on June 25, 2019 during the 2019 Seeps and Springs Survey. The Annual Seeps <br /> and Springs Survey notes and photo log are included in Appendix 4. The analytical laboratory <br /> reported QC issues during the analysis of the 2019 Whirlwind samples, and the samples had to <br /> be reanalyzed. The reanalysis delayed the delivery of the data, and the analytical data were not <br /> available at the time of this report. The analytical data will be reported in the Q3 2019 report. <br /> EFRI will continue to include the Rajah Spring in future annual 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 are summarized in Appendix 2, Table 5. <br /> Waste Rock <br /> No ore was mined and no waste rock was produced in the second quarter 2018. 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 /> 3 <br />
