SHELTON, Director <br /> April 3, 1987 <br /> Mr. Jeffrey W. Todd <br /> AMAX Mineral Resources Company <br /> 1707 Cole Boulevard <br /> Golden, Colorado 80401 -3293 <br /> Re: Pre-Amendment File Review - Climax Molybdenum Company - Climax Mine - <br /> File No. M-77-493 <br /> Dear Mr. Todd: <br /> We have completed a general review of File No. M-77-493 and this letter <br /> discusses some of the various issues that should be addressed as you develop <br /> the permit amendment for the Climax Mine. We have attempted to compile a <br /> comprehensive review; however, it should be recognized that additional issues <br /> may arise as we continue our meetings during the upcoming field season. <br /> ` JZJ The Climax Mine is located along a heavily traveled tourist route and the mine <br /> is often used to exemplify the mining industry in the State of Colorado. AMAX <br /> has the opportunity to set the standard for excellent reclamation and to serve <br /> as a model for the mining industry. Additionally, the mine encompasses <br /> thousands of acres located within the Dillon Reservoir watershed, so <br /> inadequate reclamation at this site may cause long term adverse impacts that <br /> may jeopardize the usefulness of the reservoir. These are only a few reasons <br /> that justify the implementation of a well planned and "state-of-the-art" <br /> reclamation program at the Climax Mine. <br /> The existing mining and reclamation plans are based on a mine production rate <br /> of approximately 45,000 to 50,000 tons per day and the projected operation <br /> duration( is approximately 35 years. This production rate required 2,000 to <br /> 2,850 employees. On-site discussions during the September 16, 1986 inspection <br /> indicated that production rates had been reduced to approximately 6,000 tons <br /> per day during 1986. On February 27, 1987, it was announced that the Climax <br /> Mine will cease operations and that the mine work force will be reduced to 52 <br /> employees. These facts indicate that the reclamation schedules for the mine <br /> must be substantially revised. Also, as we have discussed, many of the <br /> technical aspects of the existing plan are inadequate to ensure successful <br /> reclamation. For these reasons, a permit amendment is considered appropriate. <br /> 423 Centennial Building, 1313 Sherman Street Denver, Colorado 80203-2273 Tel. (303) 866-3567 <br />
