#aft <br />of <br />Colorado <br />Trapper Mine - Review of Semi - Annual Geotech Report <br />Talvitie, Marcia <marcia.talvitie @state.co.us> Mon, Oct 22, 2012 at 10:01 AM <br />To: Jared Ebert <jaret.ebert @state.co.us> <br />Cc: Sandy Brown <Sandy.Brown @state.co.us >, Alysha Hernandez <alysha.hernandez @state.co.us >, Mary <br />Rodriguez <mary.rodriguez @state.co.us> <br />Hello Jared, <br />have reviewed the September 2012 Semi - annual Geotechnical Monitoring Report submitted by Trapper Mining, <br />Inc. for the Trapper Mine. The document reports the data collected by three GPS and four Inclinometer / <br />Piezometer installations for the period between April and September 2012, and was submitted as required by <br />Section 3.3.3 of the permit. <br />The cover letter explains the few disruptions to the data that occurred, and addresses the Division's previous <br />question regarding piezometer readings for station 8. The results appear to indicate that the slide mass is not <br />exhibiting any tendency toward instability or movement. Monitoring stations continue to be decommissioned as <br />mining operations advance. During the time covered in this report, installations number 5 and 6 were <br />discontinued, leaving only sites 7 and 8 for the subsequent monitoring period. <br />have no comments or concerns regarding the data presented in this report. Please contact me if you have any <br />additional questions. <br />
