<br />Cripple Creek & Victor Gold Mining Company Exhibit D Cresson Project Amendment 13 12 <br />Table D-5: Anticipated Equipment List <br />Equipment Specifications <br />Drills Rotary/percussion with 6.75-inch hole diameter / Smaller drill pre-split <br />Rubber Tire / Track Loaders 12 to 32 yds3 bucket capacity <br />Hydraulic Shovels 32 to 40 yds3 capacity <br />Haul Trucks 85-ton and 240-ton capacity <br />Dozers Rubber Tire Dozers CAT 834 or equivalent or larger class <br /> or CAT dozers of D9, D10, and D11 class <br />Track-hoes Caterpillar or equivalent 235 or larger class <br />Water Trucks 13,000 and 20,000 capacity <br />Graders Caterpillar or equivalent 16G or larger class <br />Vehicle Maintenance Includes tire trucks, lube trucks, and service trucks <br />Miscellaneous Vehicles Crew vans and bus and various light vehicles <br /> <br />3.3 Surface Drilling and Blasting <br />Surface drilling and blasting practices are not expected to change with Amendment 13. <br />3.4 Mine Area Stability <br />Documentation of mine wall stability was provided in previous submittals for the Cresson Project and are briefly described below. No changes to mine wall stability are anticipated for this amendment. Stability analysis of other facilities are discussed later in this plan. <br />The slope stability assessment of mine areas, including geotechnical slope recommendations and inter-ramp stability, is discussed in an engineering evaluation performed by Call & Nicolas, Inc (CNI) as part of the Amendment 11 permit application. In general, mining has occurred for the last 19 years to depths of greater than approximately 800 feet and at designed slope angles without observable slope failures other than occasional bench raveling. The CNI engineering evaluation (provided in Amendment 11) also addresses mine area stability as it relates to permanent manmade structures, as discussed in Exhibit T. <br />As discussed above, the Schist Island area of the North Cresson mine area will be modified as part of this Amendment 13. The inter-ramp slope angles recommended for the Globe Hill and Schist Island mine areas, provided in Table D-6, remain applicable under this amendment.
