CRIPPLE CREEK & VICTOR GOLD MINING Co. <br />ANGLOGOLD ASHANTI (COLORADO) amec <br />SQUAW GULCH (VLF) WEEKLY REPORT foster <br />wheeler <br />Material hauled from the Surge area was placed and compacted as structural fill per project <br />specification between Bench L stations L4 +00 to L11 +00 in Phase 1 and upslope of Bench N <br />stations N0 +00 to N14 +00 in Phase 2. A Cat 330C excavator with a hammer attachment broke <br />oversize material to meet project specifications for structural fill. <br />Spent Ore: <br />Mine Operations hauled and stockpiled spent ore in the PSSA using Cat 793 haul trucks and a <br />Cat dozer. Spent ore elevations were maintained above the drain cover fill grade by at least 20 <br />feet for 793 haul traffic. <br />Ames placed spent ore around the high volume solution collection system (HVSCS) riser piping <br />above the moscoe moss screen section. Amec confirmed that rubber tired and dozer equipment <br />stayed clear of the riser pipes during placement and that lift surfaces were scarified prior to <br />placement of subsequent lifts. <br />HVSCS 24" vertical steel risers were extended in 40' sections. The HVSCS piping was welded <br />into place and included level indicator piping. Adjustments were made by Ames surveyors to <br />ensure proper installation. The pipes were wrapped with geomembrane before burial. <br />Subgrade: Phase 1 and 2 rough subgrade preparation occurred. The area between A -Bench <br />and C -Bench was compacted per project specifications with a Cat smooth drum roller. No <br />additional subgrade was approved during this reporting period. <br />Cameron Site: SLF processing continued at the Cameron Site <br />Underdrain System: <br />Primary Underdrain: Complete. <br />Secondary Underdrain: No work was performed during this reporting period. <br />Tertiary Underdrain: No work was performed during this reporting period. <br />Leak Detection: No work was performed during this reporting period. <br />B) Underground Workings: <br />Confirmatory drilling occurred at the Anaconda Mine Complex. Additional remediation is <br />required. <br />Confirmatory boreholes were grouted at underground workings #6460. <br />Underground workings #6460 was coned with Cat 330 and 312 excavators in preparation for <br />concrete plugs. No concrete plug placement occurred during this reporting period. <br />Production drilling and blasting followed by slope grading occurred within the limits of the <br />Anaconda Mine Complex for subsequent geogrid placement. <br />II) Storm Water Management <br />Best Management Practices (BMPs) are being performed. <br />
