The sand and gravel being mined is modelled as cohesionless. Therefore, the driving property <br /> of slope stability will be the friction angle of the material (45°). <br /> In the Reclaimed Condition, the mining slope is backsloped to 3H:1V, depending on location. <br /> Given that the slope angle is lower than the friction angle it is expected that the lowest Factor of <br /> Safety failure slope will be greater than unity. The GALENA model results of the Bishop's <br /> Method of Slices shows the location and extent of the failure circle. <br /> Table GS-2 lists the analysis conducted and their respective factors of safety. <br /> GALENA data tables and analysis result figures are attached as Appendix GS-1. <br /> Pit Number One GS-2 Lcwicki&Associatcs <br /> April 2025 <br />
