In this regard, <br />Cotter intends to conduct drilling efforts and, as necessary, install a well or wells in the <br />vicinity of the:ID-6 Mine. The purpose of this exercise will be twofold. First, the <br />drilling will aid in establishing whether water is actually encountered in these formations <br />and concurrently whether a true aquifer exists. Second, if water is encountered, a <br />monitoring well or wells will be installed in order that samples of the water can be <br />collected and analyzed to determine the chemical characteristics and metals content <br />within the water at that location. <br />In addition to the above drilling and monitoring efforts, Cotter's hydrology contractor <br />(Mr. Peter Kearl) will be preparing further analyses regarding [he Divisions concern <br />about local fault conditions and the inability for waters at the surface to impact <br />groundwater near the mining operation. <br />Cotter would like to schedule a meeting with appropriate members of your staff to <br />determine the location and analytical regimen to be applied to samples collected from the <br />location or locations identified. We will be contacting Mr. Russel Means of your Grand <br />Junciiorroffice to arrange the meeting. <br />If you should have any questions concerning our plans for further study, please contact <br />our Western Slope Mining Manager Mr. Glen Williams at our Nucla, Colorado office. <br />Sincerely, <br />~~i~~'r- `-- <br />Steven D.
