amecs <br />October 12, 2008 <br />Mr. Marc Tidquist <br />Cripple Creek & Victor Gold Mining Company <br />Post Office Box 191 <br />100 North Third Street <br />Victor, Colorado 80860 <br />Re: Proposed Phase II Berm Power Poles <br />Dear Marc: <br />Project 842011250 <br /> <br />AMEC Earth & Environmental (AMEC) has prepared this letter report for the Cripple Creek & <br />Victor Gold Mining Company (CC&V) providing an assessment of the proposed power poles to <br />be located on the Phase II toe berm. According to the information provided, approximately three <br />power poles will be located along the slope of the toe berm. Each pole will be installed in holes <br />augered approximately 8 feet below the ground surface. <br />According to the American National Standards Institute [ANSI] 05.1 (1992), standard wooden <br />power poles will only impart approximately 2,000 lbs of horizontal pressure under load (static <br />and live load) to the surrounding ground. This load is several orders of magnitude less than the <br />current applied loading on the berm, and will not have any affect on the stability or performance <br />of the Phase II toe berm. The Phase 11 toe berm is designed to withstand significantly more <br />loading than can be imparted by the three proposed power poles. <br />AMEC appreciates this opportunity to assist CC&V on this project. Please contact me if you <br />have any questions or comments at (303) 433 - 0262. <br />Sincerely, <br />AMEC Earth & Environmental, Inc. <br /> <br />John F.
