MANAGEMENT <br />On behalf of McClane Canyon Mining, LLC, enclosed is an application for a technical revision to <br />eliminate alluvial well GW -3 from the mine's hydrologic monitoring program. GW -3 was <br />installed to monitoring future Munger Canyon Mine disturbances. Since the Munger Canyon <br />Mine will achieve phase III bond release this year, monitoring well GW -3 should be reclaimed <br />and removed for the McClane Canyon Mine monitoring program. Additionally, GW -9 serves as <br />McClane Canyon Mine's down gradient monitoring well. <br />Please feel free to contact me if you have any questions. <br />Sincerely, <br />J. E. Stip <br />J. E.
