Approximate projected acreage, anticipated recoverable tons, duration of mining, and WRL <br /> acreages are shown in Table 1 for each phase. To calculate anticipated recovered tons, a mining <br /> rate of one-million tons per year was used for Pre-mining/Opening and Phase 1 approximations. <br /> While for Phases 2—5, including bedrock and gravel mining, a rate of 2.5-million mined tons <br /> per year was used to approximate the duration of mining. <br /> 6.4.4(e)(i) <br /> See Table 1. Mining Phase Dimensions. <br /> 6.4.4(e)(ii) <br /> See Table 1. Mining Phase Dimensions. <br /> 6.4.4(f)(i) <br /> Metamorphic rock blasting and mining will reach a depth of approximately 7,850-foot elevation. <br /> This is below the pre-mine ground surface (Maps C-7 and F-1). Mining depths with respect to <br /> the highest ridge point are included on Table 2. Mining Depths. The highest pre-mining ground <br /> surface elevation will be approximately 8,500 feet and the final post mine elevation is 7,850 feet. <br /> The thickness of the deposit is beyond what will be mined under this permit. The gravel overlies <br /> the bedrock units and is 350 feet thick along the center of the site near the CCP and thins to 0 <br /> feet along the western extent of the site (Figure 1). <br /> Young Ranch Resource <br /> December 2021 D-12 Lewicki & Associates <br />
