RESPONSE: We do not believe it possible to answer this question in the <br />form put. The issue is much more complicated than this formulation of <br />the question implies. <br />How the information regazding the cause of the landslide pertains to current and future <br />mining and reclamation operations at the Trapper Mine. <br />RESPONSE: Because of the complexity of analyzing and delineating the <br />cause and physical effect of the landslide, as suggested in our responses <br />to the above, compounded by the difficult economic issues associated <br />with the answer to this question, we do not believe we will be able to <br />comment on the issues raised by your question for at least twelve to <br />eighteen months. As stated above, however, Trapper intends to comply <br />fully with its reclamation obligations regarding the area affected by the <br />landslide. <br />2. The printouts of dewatering well data provided to Division personnel during the October 10- <br />12, 2006 Division inspection plot information from the date each well was drilled through the <br />date of the landslide. Unfortunately, given the horizontal scale of these charts, the data points <br />plot too close together to accurately discern water level behavior at discrete collection dates. <br />Please resubmit these charts with dewatering well data over the period from just October <br />2005 to October 2006. <br />RESPONSE: Trapper will provide this information to you no later than <br />December 8, 2006. <br />3. Please enlazge the information provided on the "Geotechnical Monitoring Dewatering Wells" <br />map for the dewatering wells in the G-dip and G-strike mining azeas. The font size used for <br />the dewatering well labels on the map was so small as to make the label illegible. Please also <br />provide information pertaining to the depth and screened interval for each well. <br />RESPONSE: Trapper will provide this information to you no later than <br />December 8, 2006. <br />4. Dewatering wells DW 2, DW 23, DW 24, DW 26, DW 27, DW 28, G1, and GP1 test were <br />identified on the water level data plots provided to the Division during the October 10-12, <br />2006 Division inspection. We are, however, unable to locate these particulaz wells on the <br />"Geotechnical Monitoring Dewatering Wells" map. Please resubmit this map with these <br />wells located on this map. If any of these wells have been mined through or abandoned, <br />please provide a description of the disposition of those wells. <br />RESPONSE: Trapper will provide this information to you no later than <br />December 8, 2006. <br />During October 10-12, 2006 Division inspection, John Tinucci of Agapito Associates, who <br />attended the inspection, stated to Division personnel that he had been conducting geologic <br />monitoring at the Trapper Mine. Please discuss the type of monitoring that was Mr. Tinucci <br />was conducting, the reason(s) for this monitoring, the duration of the monitoring, the <br />4 <br />
