southern cliff face when the CCP is realigned. Safeguarding this landform in its undisturbed <br /> state, excepting the wildlife crossing across the realigned CCP, both maintains the existing <br /> wildlife migration corridor/habitat along this portion of the CCP and allows this existing natural <br /> landform to function as a shield for the mine area as seen from the I-70 corridor. The WC, <br /> therefore, also preserves the overall mountain aesthetic of the I-70 corridor. <br /> The geologic units to be mined are Precambrian metamorphic bedrock, Cretaceous intrusive <br /> rocks (Kqm), and a Neogene boulder gravel (Tbg). The gravel overlies the bedrock units and is <br /> thickest along the center of the site near the CCP and thins to 0 feet along the western extent of <br /> the site. The underlying Precambrian interbedded felspar-rich(Gnmi), hornblende (Gnmh), and <br /> biotite gneiss (Gnbs) is cut by a Cretaceous intrusive porphyry. Talus (Qt) sporadically overlies <br /> the above detailed units. Figure 1 shows cross sections through the site with expected bedrock <br /> contacts. Cross section alignments are shown on Map C-2. <br /> Young Ranch Resource ' <br /> February 2020 D-3 <br />
