TRAPPC6 I~ININ61pC. <br />March 24, 2008 <br />Mr. Jason Musick ~~~~~~ <br />Environmental Protection Specialist <br />Colorado Division of Minerals and Geology ~fA~ ~ 7 2008 <br />1313 Sherman Street, Room 215 t7ivssioro of reclamation, <br />Denver, CO 80203 Mining and Safety <br />Dear Ms. Binns: <br />Re: Semi-annual Geotechnical Monitoring Report -March 2008, <br />Trapper is monitoring assorted benchmarks, inclinometers and piezometers that have <br />been installed to evaluate the landslide area. In accordance. with the reporting <br />requirements approved in TR-99, Trapper is submitting a monitoring report that shows <br />results to date. During much of the most recent reporting period, certain sites were not <br />accessible due to winter conditions. <br />A total of 16 sites were developed in and near the slide area. These holes were completed <br />in March, May and July of 2007 and represent a joint planning effort involving Trapper <br />and Agapito Associates Inc. (AAI). The program was approved by DRMS under two <br />separate MR's (MR-212 and MR-213). The following table identifies the actual sites and <br />any associated instrumentation. <br />Site ID # Dates Drilled (2007) Total Depth Comments/Instrumentation <br />07-GI1-CCR May 8-9 178.2 benchmark <br />07-GI2-CCR March 6-7 170.0 inclinometer <br />07-GI3-CCR Mazch 9-12 180.4 piezometer, video <br />07-GI4-CCR March 13-15 220.5 benchmark <br />07-GIS-CCR March 15-16 127.5 benchmazk <br />07-GI6-CCR Mazch 22-23 197.0 benchmark <br />07-GI7-CCR Mazch 19-21 227.0 benchmark <br />07-GI8-CCR July 23-24 175.0 none <br />07-GI9-CCR July 18-20 187.7 none <br />07-GI10-CCR July 25-27 207.0 piezometer <br />07-GX1-CCR March 2-5 120.9 benchmazk <br />07-GX2-CCR Feb 27 - Maz 1 141.0 benchmazk <br />07-GX3-CCR May 30 149.0 benchmazk <br />07-GX4-CCR May 31 -Jun 1 191.0 benchmazk <br />07-GXS-CCR May 9-10 158.0 piezometer <br />07-GX6-CCR May 14-15 179.0 inclinometer <br />07-ZI1-CCR May IS-17 138.5 inclinometer <br />07-ZI2-CCR May 17-18 168.0 piezometer (inactive) <br />07-ZI3-CCR May 21-29 188.5 none <br />P.O.
