TRAPPER MININD INC. <br />September 23, 2008 <br />Mr. Jason Musick <br />Environmental Protection Specialist <br />Division of Reclamation, Mining and Safety <br />1313 Sherman, St., Room 215 <br />Denver, CO 80203 <br />RE: Semi-annual Geotechnical Monitoring Report <br />Dear Jason: <br />RECEIVED <br />SEP 2 9 2008 <br />Division of Recla?nation, <br />Mining and Safety <br />The following information is submitted in response to comments from your July 29, 2008 <br />letter related to Trapper's Semi-annual Geotechnical Monitoring Report (GMR). <br />DRMS Comment 1) - Table 3.3-3 includes proposed lengths (in feet) for the three <br />inclinometers and four piezometers installed. These lengths differ from those reported <br />in the GMR (some are longer; some are shorter). Please provide an explanation of the <br />variations in length of instrumentation between Table 3.3-3 and the GMR. Table 3.3-3 <br />was derived based on estimates of depths to penetrate or monitor certain zones of <br />strata. The depths were not the critical parameter, rather the zones of interest were. A <br />description is provided below: <br />Site G12-CCR - This inclinometer site was projected to penetrate the Q floor. Q seam <br />exists for the interval 145.8-157.6. The actual depth of 170 feet extends approximately <br />12 feet below the Q floor. Sites GX6-CCR and Z11-CCR vary from the estimated <br />lengths for the same reason. These holes were drilled at varying lengths through the Q <br />seam floor as intended <br />Site G13-CCR - This piezometer site was designed to monitor three zones, namely the <br />zone above the ML seam (106 feet), the zone above the MM seam (126 feet) and the Q <br />seam (163 feet). The total length of the three piezometer cables is 395 feet which <br />matches fairly closely with the 390 feet in Table 3.3-3. Lengths for sites GX5-CCR (346 <br />total feet) and Z12-CCR (396 total feet) varied for the same reason <br />Site G110-CCR - This piezometer site was originally designed to monitor only one zone <br />but the decision was made by Agapito to monitor the same three zones as in site GI3. <br />The fact that there were 3 monitoring zones added additional piezometer length. <br />Monitoring installation was supervised by Agapito Associates and was placed in the <br />desired zones. <br />P.O.
