For these reasons, we ask that a letter be written to the DRMS (Bob Oswald of the Durango <br />office) that this in -mine drilling and re -hab work be allowed without a permit. It is also important <br />to note that Silver Star has committed to monitoring the flow, pH and TDS of the flow in the <br />Yellow Rose drift throughout the exploration program. If any increase in flow is detected, the <br />operation will conduct field parameter tests for pH, temperature, TDS and flow. If any of these <br />values is markedly different from the baseline condition, the activity will stop, a sample will be <br />sent to the lab for a full suite test and both the DRMS and the CDPHE will be consulted. <br />Cc: Bob Oswald Colorado Division of Reclamation, Mining, and Safety <br />61 1 <br />Sincerely, <br />,e,„„1:, <br />Greg Lewicki, P.E. <br />Ben Langenfeld, E.I.T <br />Greg Lewicki and Associates <br />
