TRAPPER MINING INC. <br />March 24, 2016 <br />Ms. Tabetha N. Lynch <br />Environmental Protection Specialist RECEIVED <br />Colorado Division of Reclamation, Mining, and Safety <br />1313 Sherman Street, Room 215 <br />Denver, CO 80203 MAR 2 9 2016 <br />Dear Ms. Lynch: DIVISION OF RECLAMATION <br />MINING & SAFETY <br />RE: Semi-annual Geotechnical Monitoring Report — March 2016 <br />Trapper Mining Inc. (TMI) began submitting semi-annual monitoring reports to the Division, beginning March <br />2008 with the last report completed on September 28, 2015. TMI has been monitoring the 2006 landslide area <br />for movement through the use of a continuous monitoring system. <br />Section 3.3.3 of TMI's permit details the initial configuration of the monitoring system. Currently, there are three <br />sites (site 8, site 10 and site 11) that are monitoring the area. A map has been attached showing the location of <br />these sites. <br />Displacement graphs for all three sites covering the time period of September 24, 2015 through March 24, 2016 <br />are attached. The monitoring software does not allow the option of picking particular dates to graph. There are <br />a few spikes in the graphs. The system has a filter that is supposed to remove these spikes but some corrupted <br />data still passed through. All sites have shown minimal amount of movement. <br />An inclinometer graph for site 8 has been attached. This graph has shown minimal amount of movement. <br />TMI's Permit Revision 7 (PR7) has been approved. TMI submitted a Technical Revision 115 (TR -115) <br />requesting to remove the slope monitoring requirements from the permit. This revision is currently in the public <br />review process. TMI is working on submitting a new ground control plan that will do away with the slope <br />monitoring plan that is currently in TMI's ground control plan. <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 />
