Newmont Mining Corporation ■■ <br /> Cripple Creek&Victor Gold Mine ■ <br /> VLF2 Phase 2 CQA <br /> NewFields Job No.475.0106.032 <br /> Week Ending Saturday,June 8,2019 <br /> 1.0 EARTHWORKS <br /> 1.1 Underground Working Remediation <br /> No activity during this reporting period <br /> 1.2 Structural Fill <br /> Structural fill placement continued within the VLF2 Phase 2 footprint. NewFields personnel <br /> inspected fill material and observed placement and compaction procedures to ensure that they <br /> were in accordance with the project technical specifications. Ambient and fill material <br /> temperatures were monitored and recorded during fill placement to ensure that no frozen <br /> material was placed or compacted in the area. The following structural fill construction <br /> activities occurred during the shift: <br /> Slope rough grading (cut to fill) in areas at bench stations: <br /> o K23+00 to K30+00 <br /> o Haul Road 54+00 to 60+00 <br /> Articulating haul trucks were used to haul oversized and unsuitable material away to an <br /> area of waste <br /> Compaction of structural fill was achieved using a vibratory sheepsfoot compactor <br /> 1.3 Subgrade <br /> No additional areas of Subgrade were accepted during the reporting period. Figure 2 shows the <br /> current areas of accepted subgrade. <br /> 1.4 Soil Liner Fill <br /> SLF placement was performed in the areas shown on Figure 3. Subgrade was approved and <br /> moisture conditioned and compacted (when required) prior to SLF placement. SLF material was <br /> hauled to the Phase 2 VLF from the Dump 1 stockpile using articulating haul trucks. The <br /> material was then spread with low ground pressure CAT dozers equipped with GPS. Moisture <br /> conditioning of SLF material was performed in place using a water truck, and compaction was <br /> achieved using a 19-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. <br /> SLF processing continued at the Dump 1 processing plant. <br /> Page 2 <br />
