Evaluation of CR82 with North Area Mines Slope Stability <br /> There are two locations where the road is close to the pit excavation, as seen_ on Map C-Ia. The <br /> slope stability of the north mine excavations was evaluated in a Study done by Call and <br /> Nicholas, Inc. in November of 2015 for Amendment 11 titled"Geotechnical Slope <br /> Recommendations for the North Area Underground Mining Areas". This Study performed <br /> detailed evaluations of various critical slopes using extensive data, drilling, rock type analysis <br /> and modeling, etc. The Study is included in Appendix 5 of Volume III in Amendment 11. Call <br /> and Nicholas (CNI) have performed numerous studies of slopes at the mine beginning in 2005. <br /> All knowledge from the previous studies, field tests, observations, lab tests and drilling, RQD <br /> analysis, etc. were incorporated into the November 2015 Study. <br /> The Report Certification is given below. <br /> 2 <br />
