Newmont Mining Corporation a�• <br /> Cripple Creek&Victor Gold Mine ■ <br /> Squaw Gulch VLF CQA <br /> NewFields Job No.475.0106.006 <br /> Week Ending Saturday,July 09,2016 <br /> 1.0 EARTHWORKS <br /> 1.1 Underground Working Remediation <br /> Confirmatory drilling was performed to a depth of 50-feet at the upper Anaconda Mine <br /> Complex. NewFields personnel observed drilling activities and noted any voids that were <br /> encountered. Further remediation is required. <br /> 1.2 Structural Fill <br /> Structural Fill placement continued within the Squaw Gulch VLF Phase 1 footprint. NewFields <br /> personnel inspected fill material and observed placement and compaction procedures to <br /> ensure that they were in accordance with the project technical specifications. Ambient <br /> temperatures remained above 32 degrees Fahrenheit throughout the shift. The following <br /> structural fill construction activities occurred during the shift: <br /> Bench construction along the Phase 110,050 foot contour <br /> Compaction was achieved using a smooth drum roller <br /> 1.3 Subgrade <br /> Subgrade was prepared for SLF placement in the Squaw Gulch area between the 9850 and 9950 <br /> benches. Figure 1 shows the subgrade acceptance areas. <br /> 1.4 Leak Detection Trench <br /> Approximately 125 feet of leak detection trench were constructed along the High Grade Mill <br /> slope in accordance with the project technical specifications. <br /> 1.5 Soil Liner Fill (SLF) <br /> Soil Liner Fill processing continued at the Dump 1 processing plant. Approximately 175,209 dry <br /> tons of material has been processed as of Saturday,July 8, 2016. <br /> Soil Liner Fill (SLF) placement was performed in the areas shown on Figure 2. Subgrade was <br /> approved and moisture conditioned (when required) prior to SLF placement. SLF material was <br /> hauled to the Phase 1 VLF from local stockpiles using CAT 740 haul trucks. The material was <br /> then spread by low ground pressure CAT dozers equipped with GPS. Moisture conditioning of <br /> SLF material was performed in place using a tandem-axel water truck, and compaction was <br /> achieved using a 10-ton vibratory smooth drum compactor. Moisture content verification, <br /> nuclear density testing, and depth verification were performed, with results meeting the <br /> required project technical specifications, prior to accepting the surface for geomembrane <br /> installation. All test locations were surveyed by Ames. <br /> Page 2 <br />
