DP Spring <br /> The field parameters were measured at DP Spring on March 27, 2020. The flow is measured by <br /> timing the fill rate of a five-gallon bucket. Field parameters from DP Spring are measured in the <br /> stock tank located at the spring. The field sampling form is provided in Appendix 3. <br /> Flow rates and field parameters at DP Spring are summarized in Appendix 1, Attachment 4. <br /> PR Spring <br /> The field parameters were measured at PR Spring on March 27, 2020.

The <br /> 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 /> 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 /> 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 2019. 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 the Second Quarter Report. The <br /> analytical laboratory data are provided in the Third Quarter Report. EFRI will continue to <br /> include the Rajah Spring in future annual seeps and springs surveys. <br /> 2 <br />
