• 13.13 Climate <br />Climatic data, including evaporation, mean annual precipitation, temperature and average <br />wind direction, are provided in Section 4.10 of the Project Description. <br />13.14 Geochemical Data and Analysis <br />Information addressing the geochemical evaluation of the materials to be mined as part of <br />the MLE operations is provided above in Section 4.5 of this Project Description and in <br />Appendix 1, Volume II. The geochemical evaluation was conducted on rock samples <br />from drilling throughout the Cresson Project and from blast hole data, and is considered <br />representative of the materials to be mined or stockpiled or backfilled. The geochemical <br />evaluation also included an analysis of the reasonable sources, probable fate, and <br />transport mechanisms of metal and acid-producing minerals that may be mobilized <br />during operations and reclamation. <br />Acid base accounting was conducted for the entire rockmass that will be mined from now <br />until the completion of the proposed MLE. The methodology used was to identify for <br />each 50' x 50' x 35' block of material that will be mined the expected total sulfur and <br />total carbon concentrations, based on a total of 30,758 LECO furnace analyses. A total of <br />42 long-term accelerated weathering tests of samples of the rockmass in and adjacent to <br />the diatreme were completed using the ASTM Test Method D5744-96, Standard Test <br />Method for Accelerated Weathering of Solid Materials Using a Modified Humidity Cell. <br />The results of the analysis indicate that no deleterious change in the average regional <br />ground water quality from the District will occur due to current or proposed mining. <br />13.15 Construction Schedule Information <br />The Phase 5 VLF is the only new facility proposed as part of the MLE which will contain <br />or use designated chemicals. The existing VLF and ADR facilities will continue to <br />contain or use designated chemicals with no new construction planned for these facilities. <br />The anticipated construction schedule for the Phase 5 VLF is discussed in Sections 5.4 <br />and 6.3 of this Project Description and in Appendix 8, Volumes V through VI. <br />Construction of Phase 5 of the VLF is anticipated be begin in 2009 and will take <br />approximately 3 construction seasons to complete. Utilities within the Phase 5 new liner <br />footprint will be relocated in 2009, followed by preparation of the subgrade. The SLF is <br />expected to be constructed in 2010. The liner is expected to be placed in 2011. The actual <br />construction schedule will depend on various factors, with weather conditions during the <br />construction season being an important consideration. <br />• Cripple Creek & Victor Gold Mining Company <br />Cresson Project Mine Life Extension <br />13-10
