ORIGINAL-PUBLIC FILE <br />(Page 2) <br />MINE ID # OR PROSPECTING ID #: nn_I9Rn-sae <br />INSPECTION DATE: ~/~9/ns INSPECTOROS INITIALS: -8J~ <br />OBSERVATION <br />The Division conducted a monthly monitoring inspection of the site on <br />8/29/05. The area had received measurable precipitation the last few days, <br />which were evident with the very small ponded water, noted through out the <br />permit area. The inspection began at the Phase IV leach pad expansion area, <br />where the operator explained what they had done to make sure the low volume <br />solution collection pipes were operating as designed. Due to being buried <br />with ore as approved in the design, the small PVC pipes were being <br />compacted due to the weight of the ore. CC&V plans to replace these small <br />pipes with steel or other durable pipes. The temporary fix appears to be <br />working well and there was no exceedance of the two feet hydrostatic head <br />because if the slight constraint of fluid flow at any time during the <br />operation. The numbers recorded in the operation logbook were below the two <br />foot limit. Continued the inspection to Iron Clad old mill tailings area <br />where CC&V had undertaken the reclamation of the old mill tailings. As <br />reported in the earlier inspection, topsoil had been replaced and seeding <br />is to commence in the fall. There was no drainage problem noted. DMG plans <br />to recommend CC&V for reclamation award for completing the task at the <br />Division's request earlier than required. Storm water management structures <br />in the area were found to be in good repair. Inspected the West and Main <br />Cresson areas, they were both active at the time of the Inspection. East <br />Cresson backfill was also continuing. First lift is completed and the <br />second lift backfill has started. Inspected the Portland pit area. As <br />reported in earlier inspection reports, the pit has been backfilled and top <br />soil was being placed along the North Facing Slopes at the time of the <br />inspection. <br />Inspected the Phase I, II, III AND IV High and Low Volume Solution <br />collection areas and recorded the following readings from transducers. <br />Phase I High Volume solution Collection Transducer # 1 read out gauge was <br />still not functioning, as noted in the earlier inspection reports, it will <br />be replaced once the pump repair is needed # 2 was at 52.5 and #3 was at <br />53.5. Low volume # 1 was recorded at .20 and # 2 was at.26.Piezometer for <br />the pond was measured at 52.3 feet. Phase IIAND III High Volume solution <br />collection transducer #4 was recorded at 38.4 #5 was at 36.5 and # 6 was at <br />41.5. Low volume solution collection transducer # 1 was at .15 and # 2 was <br />at.48. Phase IV high volume solution collection transducer # 7 was recorded <br />at 46.5 # 8 was at 45.3 # 9 was at 47.5 and # 10 was at 47.5.Low volume <br />solution collection transducer # 1 was recorded at 18.5 and #2 was at 3.1 <br />inches of hydrostatic head. Inspected the External pond, it was holding <br />some water, readings from the Low volume solution collection transducer # 1 <br />was at 13.0 sand # 2 was at .8.9 inches of hydrostatic head. <br />Inspected the under drain area, all the lower ponds were holding a very <br />small amount of water from the recent rain fall the area received, the past <br />few days. The south and four inches pipes were discharging at measurable <br />flow, more than what was noted in the last inspection report, reflecting <br />
