Characterization of mine water in the Packrat Mine could not be conducted, because the mine is <br /> not yet accessible. Appendix 1, Attachment 3 of this report is reserved for field data collected <br /> from the Packrat Mine at such time that it becomes accessible and is monitored. <br /> DP Spring <br /> During the first quarter of 2021, EFRI Field Personnel attempted to access the Mine. Due to the <br /> county road conditions, the Mine was inaccessible during the quarter, and therefore, the quarterly <br /> water level/flow measurements and field parameters from the monitoring well, DP Spring and <br /> PR Spring could not be collected. <br /> Historic flow rates and field parameters at DP Spring are summarized in Appendix 1, <br /> Attachment 4. <br /> PR Spring <br /> During the first quarter of 2021, EFRI Field Personnel attempted to access the Mine. Due to the <br /> county road conditions, the Mine was inaccessible during the quarter, and therefore, the quarterly <br /> water level/flow measurements and field parameters from the monitoring well, DP Spring and <br /> PR Spring could not be collected. <br /> Historic flow rates and field parameters at PR Spring are summarized in Appendix 1, Attachment <br /> 5. The historical analytical data from PR Spring are summarized in Appendix 2, Table 2. <br /> Monitoring Well W-1 <br /> Monitoring Well W-1 was installed on October 12, 2008 for the purpose of characterizing and <br /> monitoring groundwater quality downgradient of the waste rock storage area. <br /> During the first quarter of 2021, EFRI Field Personnel attempted to access the Mine. Due to the <br /> county road conditions, the Mine was inaccessible during the quarter, and therefore, the quarterly <br /> water level/flow measurements and field parameters from the monitoring well, DP Spring and <br /> PR Spring could not be collected. <br /> The historical analytical data from Monitoring Well W-1 are summarized in Appendix 2, Table <br /> 3. <br /> 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 <br /> events are scheduled at this time. <br /> 2 <br />
