TRAPPER MINING INC. <br />September 25, 2013 <br />Mr. Jared Ebert C <br />REEIVE® <br />Environmental Protection Specialist v <br />Colorado Division of Reclamation, Mining, and Safety <br />1313 Sherman Street, Room 215 SEP 2 1 2013 <br />Denver, CO 80203 <br />DMSION OF RECLAMATION <br />Dear Mr. Ebert: UNING AND SAFETY <br />RE: Semi - annual Geotechnical Monitoring Report — September 2013 <br />Trapper began submitting semi - annual monitoring reports to the Division, beginning March 2008 with the last <br />report sent on March 27, 2013. Trapper has been monitoring the 2006 landslide area for movement through the <br />use of a continuous monitoring system. <br />Section 3.3.3 of Trapper's permit details the initial configuration of the monitoring system. Currently, there are <br />two sites (site 7 and site 8) that are monitoring the area. A map has been attached showing the location of <br />these sites. Inclinometer, piezometer and surface displacement graphs for both sites covering the time period of <br />March 26, 2012 through September 24, 2013 are attached. During this period, site 7 has shown minimal <br />amount of movement while site 8 has recorded a small amount of movement. <br />There was a planned power outage at the office on September 15, 2013. It took 24 hours for 3DTracker (the <br />program that collects the data) to stabilized when power was restored. After 3DTracker stablilized, the GPS <br />data for sites 7 and 8 did not go back to the original displacement values. After several failed attempts to get <br />the data back to the previous values, it was decided to reset the baselines. This is shown in the two GPS <br />graphs as the values went to zero. <br />Since the last report, consultants hired by Trapper recommended that a buttress be placed below site 8 to <br />prevent or minimize any possible slope failure. The Q and R seam floor was prepped and the area was <br />buttressed up to the L seam. This did slow down the movement that was seen at this site. Trapper will <br />continue to inspect this area on a regular basis. <br />Please contact me if you have any questions. <br />Sincerely, <br />Tonia Perkins, P. E. <br />Senior Mining Engineer <br />P.O. Box 187 Craig, Colorado 81626 (970) 824 -4401 <br />
