CRIPPLE CREEK & VICTOR GOLD MINING Co. <br />ANGLOGOLD ASHANTI (COLORADO) <br />SQUAW GULCH (VLF) WEEKLY REPORT <br />amec <br />foster <br />wheeler <br />Spent Ore: <br />Mine Operations hauled and stockpiled spent ore (SO) in the PSSA using Cat 793 haul trucks <br />and a Cat dozer for approximately a half day during the first part of the week. Spent ore <br />elevations were maintained above the drain cover fill grade by a minimum of 20 feet for 793 haul <br />truck traffic. The spent ore haul was completed on March 8th. <br />Approximately 8 feet of spent ore was excavated from the ADR2 engineered fill footprint (9439 to <br />9447 -foot elevation) and replaced with a mixture of SO and Low Volume Solution Collection Fill <br />( LVSCF) in the PSSA engineered fill area. LVSCF was hauled from the stockpile to the PSSA <br />with Cat 777 haul trucks. The fill was placed and compacted beneath the footprint of the ADR2 <br />spent ore working platform at the 9450 elevation. CQA monitoring was then conducted by New <br />Fields. <br />Ames placed SO around the high volume solution collection system (HVSCS) riser piping and <br />confirmed that they were vertical plumb by surveyed prisms atop the risers. Amec confirmed that <br />rubber tired and dozer equipment stayed clear of the riser pipes during placement. <br />Subgrade: Phase 1 and 2 subgrade preparation continued per project specifications. Subgrade <br />was approved on the PSSA toe berm. <br />Cameron Site: SLF processing continued periodically 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 />Workings UG 6010 and UG 6631 were prepared for geogrid placement. Further remediation is <br />required. <br />Confirmatory drilling occurred at the west side of the Anaconda Mine Complex and shot rock was <br />removed from the lower portion of the working. Additional remediation is required. <br />Confirmatory drilling occurred at working UG 6670. Additional remediation is required. <br />Drilling was preformed for blasting to prepare UG 6639 for geogrid placement. <br />II) Storm Water Management <br />Best Management Practices (BMPs) are being performed. <br />
