CRIPPLE CREEK &VICTOR GOLD MINING Co. I® <br /> ANGLOGOLD ASHANTI (COLORADO) amec <br /> SQUAW GULCH (VLF) WEEKLY REPORT foster <br /> wheeler <br /> a layer of 12-inch minus rock, Drain Cover Fill and geofabric to complete the modified <br /> drainage area into the tertiary underdrain. <br /> A technical memo will be generated to address deviation of design with respect to the <br /> tertiary underdrain. <br /> Leak Detection: <br /> A Cat mini-excavator prepared approximately 200 LF of leak detection trench. The leak detection <br /> was completed per project plans and specifications between stations FM15+00 and FM17+00. <br /> Miscellaneous: <br /> Amec personnel continued LVSCS pump monitoring and observation. <br /> B) Underground Workings: <br /> UG #6050: Completed two layers of geogrid installation. Completed placement and compaction <br /> of two 6-inch lifts of Select Structural Fill. Remediated. <br /> UG #6004: Step 2: Completed three layer geogrid installation. Completed placement of the three <br /> 6-inch lifts of Select Structural Fill. Cat excavators prepared subgrade for Step 3 geogrid. <br /> Further remediation required. <br /> UG #6455: Continued drilling operations, 1,150LF. Further remediation required. <br /> UG #6538: Production drilling and a production blast occurred during this reporting period. <br /> Further remediation required. <br /> UG #6687: A Cat 330 excavator excavated to competent rock (+/-20'). Backfilled and <br /> compacted per project specifications. Remediated. <br /> UG #6468: A Cat 330 excavator coned working for concrete plug. Further remediation required. <br /> C) Geomembrane: <br /> Geomembrane installation within the PSSA continued this week performing deployment, <br /> seaming, repair, and QA/QC activities. Geomembrane installation was performed at the ADR <br /> pad and PSSA northwest slope. Approximately 146,644 square feet of 80mil LLDPE <br /> geomembrane was deployed. Soil Liner Fill was inspected and approved by AMEC,Ames and <br /> ECA representatives prior to geomembrane deployment. Approximately 7,568 linear feet of seam <br /> was fusion welded during deployment using one or two fusion welding machines for each day of <br /> deployment. No extrusion welding was performed during this reporting period. Destructive and <br /> non-destructive testing was completed per technical specifications. <br /> Ames continuously excavated anchor trench ahead of geomembrane installation. After <br /> geomembrane testing was completed, the anchor trench above finished panels was backfilled <br /> and compacted per project specifications. <br /> See attached figure for approved geomembrane. <br /> II) Storm Water Management <br /> Best Management Practices (BMPs) continued to be performed. <br />
