2.9 Exhibit I: Soils Information <br /> The mine's facility and tailings storage will be developed at the toe of Greenhorn Mountain, in the <br /> vicinity of the historic Copper King Mine. According to the NRCS web survey (Appendix H), soils in the <br /> area of interest include Bronell gravelly sandy loam, Cathedral-Rock outcrop, Coaldale very gravelly <br /> sandy loam, Louviers-Travessilla complex and Sedillo cobbly sandy loam. With the exception of <br /> Cathedral,the soils are well drained sandy loam with moderately high to high water transmissivity on or <br /> near mountain slopes or terraces. The Cathedral soil is the unweathered mountain bedrock. The NRCS <br /> map unit description is provided in Exhibit H. <br /> Development will be primarily on Bronell and Louviers-Travessilla complex soils. These soil groups are <br /> suitable for reclamation activities. During development, Zephyr will salvage an average of four to six <br /> inches of suitable plant growth medium. The salvaged soil will be stockpiled for use during final <br /> reclamation. The actual depth of salvaged soil will vary as geotechnical studies in the area indicate <br /> elluvium soils overlay sandstone and shale. The shallowest soil depths are on the upper slopes and <br /> deepest at the toe of the slope. <br /> 56 <br />
