CRIPPLE CREEK & VICTOR GOLD MINING Co. <br />ANGLOGOLD ASHANTI (COLORADO) amec <br />SQUAW GULCH (VLF) WEEKLY REPORT foster <br />wheeler <br />Soil Liner Fill: <br />A Cat skidsteer, a Cat excavator with a roller attachment and Cat smooth drum rollers compacted <br />SLF surface in preparation for geomembrane deployment. <br />Cat 740 haul trucks transported SLF from the Phase 1 stockpile to stations H24+00 to H26+00. A <br />GPS equipped Cat D7 dozer and a GPS equipped Cat D6 dozer placed SLF between stations <br />H20+00 to H26+00. A Cat skidsteer placed SLF in the vicinity of station F28+00. Cat smooth <br />drum rollers compacted the fill areas. <br />Cameron SLF processing continued. <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 />Crushed Ore Fill: <br />Cat 793 haul trucks delivered Crushed Ore to station 11+00 of the ADR haul road. The Crushed <br />Ore was used to continue a 100' lift to load the PSSA to the 9550' elevation. <br />Underground Workings: <br />Confirmatory Drilling: <br />UG #6679: Sandvik 700 — 5.0 hours, 500LF. Further remediation required. <br />Remediation: <br />UG #6673: Cat dozers continued removing shot rock to prepare for geogrid subgrade. <br />Further remediation required. <br />UG #6539: A Cat excavator removed shot rock in preparation for concrete plug. <br />Additional voids were encountered. Upon further investigation, it was determined that the <br />working remediation will be geogrid instead of concrete. Began preparation for geogrid <br />subgrade. Further remediation required. <br />Underdrain System: <br />Primary Underdrain: Complete. <br />Secondary Underdrain: None. <br />Tertiary Underdrain: None. <br />Leak Detection: <br />Phase 1 leak detection complete. <br />
