Lumsden Canyon 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 events <br /> 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 2023. Field parameters and a sample <br /> were collected during the third quarter 2023, during the 2023 Seeps and Springs Survey on July <br /> 25, 2023. EFRI will continue to include the Rajah Spring in future annual seeps and springs <br /> surveys. Field parameters are summarized in Appendix 1, Attachment 8 and the historical <br /> analytical data are summarized in Appendix 2, Table 5. <br /> Waste Rock <br /> Approximately 290 tons of waste rock were removed during the third quarter of 2023.No ore was <br /> mined during the period. The Mine is currently in operation with rehabilitation, maintenance and <br /> monitoring activities being conducted. <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, including 2023, will <br /> be summarized in a future report in Appendix 2, Table 6. <br /> Sediment Pond <br /> The sediment pond has been monitored since its construction in November 2008 in accordance <br /> with DRMS stipulations. Although storm events and significant snow melt events have occurred, <br /> none have resulted in storm water discharge from the pond. As a result, no storm water samples <br /> have been collected from the pond to date. EFRI will continue to monitor the sediment pond for <br /> discharge and will collect samples in the event that a discharge is observed. <br /> Dolores River <br /> In accordance with BLM stipulations, the Dolores River is required to be monitored for selenium <br /> upstream and downstream from the confluence of Lumsden Creek when all of the following <br /> 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 River, <br /> and <br /> 4 <br />
