results are summarized Table 3 and a set of GALENA outputs are attached with more detailed <br /> information. More information on each slope condition is provided below. <br /> Table 3—Slope Stability Analysis Results <br /> Distance from • <br /> Active Slope Status slope Lowest Failure Circle to Sufficiency <br /> Final Mining& 3HAV 3.1 8Q Yes <br /> Reclaimed <br /> 3. Conclusion <br /> The final mining and reclaimed slopes are proposed to be 3H:1V. These slopes will be mined to <br /> with no backfilling proposed. An analysis of these slopes resulted in a FOS = 3.1, which is more <br /> than sufficient to meet DRMS standards regarding slope stability using general material properties <br /> (1.5). Additionally, this circular failure scenario was contained entirely on the reclaimed slope face. <br /> Therefore, the permanent slope conditions following mine reclamation pose no risk of failure outside <br /> the property or to any nearby structures. <br /> 1210812 <br /> � .... <br /> �NA1. <br /> Ben Langenfeld, P.E. #47151 <br /> Kattenberg Pit Slope <br /> Stability 3 Lewicki 81 Associates <br /> December 2022 <br />
