tailings/clay layer and the other will be at bedrock.The enclosed well design sketches explain the details <br /> of these installations. <br /> The wells will be labelled as follows: <br /> Well 1 Deep (1B) <br /> Well 1 Shallow(1A) <br /> Well 2 Deep(2B) <br /> Well 2 Shallow(2A) <br /> Well 3 Deep(3B) <br /> Well 3 Shallow(3A) <br /> Monitoring and Sampling Procedures <br /> Samples from each well will be taken immediately after installation and then 2 more samples will be <br /> taken one month after each previous sample.After the 3rd monthly sample, additional samples will be <br /> taken at 6 month intervals,which is the same schedule in the approved permit. Each of these samples <br /> will be sent to the laboratory for the full groundwater suite of analyses that are being used to test all the <br /> previous groundwater samples taken in 2012 and 2013 from inside the mine. <br /> In addition,these wells will be sampled at the same times as above for field parameters of temperature, <br /> pH, conductivity and water level.After the 3rd monthly sample is taken,future field testing will take <br /> place quarterly.The results of these tests and their evaluation will be incorporated in the DRMS Annual <br /> Report.As part of the evaluation,water chemistry from the deep and shallow wells will be compared to <br /> surface water in Sneffels and atlas Creeks,the Seep and the underground mine waters.Also, sample test <br /> data from any sediment pond discharges will be evaluated in the Annual Report. <br /> Revenue Mine TR-03 Appendix 15 Page 2 <br />
