Box 191 • 100 North 3`" Street <br />Victor, Colorado 80860 <br />(719) 689-2977 - Fax (719) 689-3254 <br />Express Mail <br />RECEIVED <br />October 3, 2008 <br />Mr. Berhan Keffelew OCT 0 6 2008 <br />Senior Environmental Protection Specialist Division or mociarnation, <br />Colorado Department of Natural Resources Mining and SSf* <br />Division of Reclamation, Mining and Safety <br />Office of Mined Land Reclamation <br />1313 Sherman Street, Room 215 <br />Denver, Colorado 80203 <br />RE: Cresson Project Permit M-1980-244: Amendment No. 9 (MLE) Application <br />Additional Response to Adequacy Review -Reclamation, High Wall Stability and <br />Hydrogeochemistry <br />Dear Mr. Keffelew: <br />Cripple Creek & Victor Gold Mining Company ("CC&V") hereby provides responses to the Amendment <br />No 9 (Mine Life Extension ["MLE"]) Application additional adequacy review comments emailed from <br />Allen Sorenson, Jared Ebert and David Bird via Berhan Keffelew. These responses are designed to <br />further clarify the information contained in the Amendment No. 9 application. These responses combined <br />with the information contained in the Amendment No. 9 application and the September 19, 2008 <br />Response to Adequacy letter comprehensively address and satisfy all requirements of the Colorado Mined <br />Land Reclamation Act and Mined Land Reclamation Board Rules and Regulations. <br />Following your review and approval of these additional responses, CC&V will place a copy of this letter <br />in each of the Responses to Adequacy Review binders that we placed with other Agencies and public <br />offices. CC&V requests that you distribute copies of this letter to the five binders that were provided to <br />DRMS. <br />DRMS Question to CC&V Adequacy Response (Allen Sorenson): <br />The Division of Reclamation, Mining, and Safety (DRMS) engineering staff has reviewed the Surface <br />Mine Slope Design submitted as appendix 5 to volume IV of the AM-09 application. DRMS has also <br />reviewed otherpotions ofAM-09 where mine slope designs are described and the drawings where the <br />mine slopes are depicted. Contrary to the statements in the September 18, 2008 Applicant's response to <br />adequacy review, is discussed in considerable detail in the application that in order for the rock slopes <br />described in AM-09 to be stable, specialized blasting to create final pit walls is required. See particularly <br />section 4.1 of appendix 5 to volume IV of the AM-09 application. This specialized blasting is inefficient <br />for open pit production, so it is only employed at the final blast to create the outside extent of any of the <br />pit walls. If the Operator were to default at some interim point in the mine plan and DRMS were to <br />reclaim the mine pits under bond forfeiture, substantial amounts of specialized blasting may be required <br />
