<br /> <br />CONCLUSIONS <br />Based on the Held examination of the Deer Creek Quarry, including visual evaluation, <br />hand held stereo photos, joint orientation assessment, geologic mapping, and the <br />cataloging of potential failure modes in different areas of the quarry, an interim stability <br />evaluation indicates that the quarry is essentially stable. No mass failures are evident or <br />expected. However, the lower soil slope adjacent to the lower access road is deformed <br />and if the slope continues to move, will result in a small volume slump on to the road. <br />Ravelling of the rocks, which will naturally take place in any rock exposure, will continue, <br />but will be controlled by the existing safety benches. No potential rock mass failures were <br />identified or should be expected. <br />This quarry is currently stable with no obvious or expected major slope failures. Future <br />stability is considered excellent as long as good, safe mining practices are adhered to and <br />the existing equilibrium is not changed by natural forces such as an increase in <br />hydrostatic pressure, erosion, or earthquake. <br />8 <br />
