CRIPPLE CREEK & VICTOR GOLD MINING Co. <br />ANGLOGOLD ASHANTI (COLORADO) am! <br />SQUAW GULCH (VLF) WEEKLY REPORT foster <br />wheeler <br />Subgrade: <br />Phase 1 areas dozed to finished grade were compacted per project plans and specifications. <br />See attached figure for approved subgrade. <br />Soil Liner Fill: <br />A Cat smooth drum roller, a Cat excavator and a water truck conditioned and compacted SLF <br />prior to geomembrane deployment. <br />Cat 777 haul trucks transported processed SLF from the Cameron area to a temporary stockpile <br />at station 48+00 of the ADR haul road. Cameron SLF processing continued. <br />Cat 777 haul trucks transported SLF to the ADR haul road between stations 16+00 to 22+00. Cat <br />dozers placed SLF between stations 14+00 to 22+00. A Cat smooth drum roller compacted the <br />SLF surface. <br />Cat dozers placed SLF below stations D0+00 to D8+00 and F12+00 to F20+00. A Cat smooth <br />drum roller compacted the SLF surface below stations F16+00 to F20+00. <br />A Cat dozer placed SLF between stations FM8+00 to FM16+00 and HM10+00 to HM16+00. <br />All of the above Soil Liner Fill material was placed, graded, and compacted per the project plans <br />and specifications. Moisture content, density testing and depth verification were performed per <br />project specification prior to surface acceptance and geomembrane installation. <br />See attached figure for approved SLF. <br />Drain Cover Fill: <br />Cat 740 haul trucks transported DCF from the stockpile to Phase 1. Low ground pressure Cat <br />dozers placed DCF on approved geomembrane in Phase 1. <br />See attached figure for approved DCF. <br />Underdrain System: <br />Primary Underdrain: Complete. <br />Secondary Underdrain: None. <br />Tertiary Underdrain: None. <br />Leak Detection: <br />A Cat excavator prepared leak detection trench between stations FM6+00 to FM8+00. A Cat <br />skidsteer assisted with construction and backfill of approximately 200LF of leak detection. All <br />work was completed per project plans and specifications. <br />Miscellaneous: <br />Amec personnel continued LVSCS pump monitoring and observation. <br />DRMS corrective action draft response to PSSA pond slope stability for Projects and ERD review. <br />
