AOC% <br />aamed,-y <br />Earth & Environmental <br />CQA ACTIVITIES: <br />SUMMARY: <br />The CQA activities performed consisted of observing, documenting and recording the construction <br />activities of the contractor. Field observations within the northwest portion of the VLF included stripping <br />of all frozen and unsuitable materials and placement of structural fill by method spec. as outlined in the <br />Project Documents. In addition, observation of the drilling which began on February 5, 2009 to delineate <br />the extent of underground mine workings located beneath the sediment collection pond and Kitty Lane <br />and Thompson Shafts located adjacent to the sub-station. Drilling was completed by February 26, 2009. <br />Clay processing was intermittent due to mechanical problems with the clay plant located in Dump 5. Site <br />visits were conducted to observe the unprocessed clay prior to screening and the processed clay. On <br />Friday the materials processing plant located in the Arequa Process Area started production of 5-required <br />materials. <br />No work was performed on Saturday, February 28`h. Currently no work activities are planned for <br />Saturdays but Ames has indicated that Saturday will be used as a make up day in the event of delay or <br />stoppage during the current planned work periods Monday to Friday. A discussion with CC&V (Tom <br />Shepard) has approved additional hours for laboratory testing, if needed. <br />Work has started this past week on the 9775 bench located on the existing heap leach for bench widening <br />for the planned re-location of the existing solution piping. The bench is planned to be 30-feet wide. <br />I. Testing Summary <br />AMEC has continued the processing of clay and structural fill samples collected during the week. An <br />additional 11 samples were obtained from the clay processing plant at Dump 5 <br />One sample (SF-3-R) was collected for the structural fill being placed along the existing haul road <br />between the 5-point intersection and the crusher area. The fill has been placed only within the limit of the <br />haul road to adjust road grading for run-off management. Fill placement has started this past week from <br />Sta. K4+00 to K8+00; 0 to 100-feet left (Sample SF-2-R represents fill from Sta. K4+00 to K8+00). All <br />fill has been placed per method spec. as outlined in the Project Documents. AMEC has discussed with <br />Ames the removal of rock in excess of 24-inches in the fill and adjacent areas that will require removal of <br />uncontrolled materials, frozen ground and excavation and removal of sediment retention areas. These <br />items were discussed with Ames and CC&V and agreed. <br />Sheet 4 of 8 VLF Weekly Report WE 02.27.09.D
