Newmont Mining Corporation <br /> Cripple Creek and Victor Gold Mining Company ` " <br /> 2016 Annual Arequa Gulch and Squaw Gulch Valley Leach Facilities Inspection ■ <br /> NewFields Project 475.0160.001 <br /> April 11,2017 <br /> has been filled with ore and the first two lifts above the ADR 2 platform have been placed, <br /> reaching an elevation of 9650' above sea level. NewFields analyzed the side slopes of the 2016 <br /> flyover SG-VLF surface, and found the ore slopes between the benches ranged between <br /> 1.4H:1V and 1.5H:1V. The design angle of repose for the ore was 1.4H:1V so actual slope are <br /> consistent with design. <br /> Additionally, to show the development and construction of the SG-VLF over the previous 5 <br /> years, NewFields created Figure 6. <br /> 2.3. Squaw Gulch Valley Leach Facility Underdrain Records <br /> CC&V provided NewFields with flow and water quality records for the SG-VLF underdrain, and <br /> NewFields reviewed them as part of the annual inspection program. For this inspection <br /> program, the review focused on the underdrain flow rates and measured WAD cyanide <br /> concentrations since these parameters will be elevated if leakage is occurring in the SG-VLF <br /> containment system. The data records reviewed for the SGUD were from November 2015 <br /> through November 2016. The underdrain was dry during this period of record. <br /> 3. CONCLUSION <br /> After completing the annual physical site inspection, analyzing the flyover topography, <br /> reviewing crack monitoring data supplied by CC&V geotechnical department and underdrain <br /> records, the AG-VLF and SG-VLF continues to perform as designed. <br /> If you have any questions or require additional information, please contact the undersigned at <br /> your earliest convenience. <br /> Sincerely, <br /> NewFields Mining Design &Technical Services Reviewed by: <br /> O` NFy�TF <br /> Jay N.Janney-Moore, P.E.
