ORIGINAL -PUBLIC FILE <br />(Page 2) <br />MINE ID # OR PROSPECTING ID #: nn-i 9s~n_~ae <br />INSPECTION DATE: ~/~(1/ns INSPECTOROS INITIALS: _B~ <br />OBSERVATIONS <br />The Division conducted a bi-monthly monitoring inspection of the site on 1- <br />20-05. Inspected the Phase IV leach pad area. More ore has been deployed in <br />the Phase IVB and C areas since the last inspection. CC&V also plans to <br />load the pregnant solution collection areas with additional ore as approved <br />in Amendment # 8, with full access to the caissons and transducers. Pad was <br />being leached at the time of the inspection. while in the area, collected <br />the following readings from the Phase IV high and low volume pregnant <br />solution collection system transducers.. <br />High volume solution collection 'transducer # 7 was recorded at 34.7 #8 was <br />at 33.8 #9 was at 34.9 and # 10 was at 35.1. Low volume solution collection <br />transducer # 1 was at 17.2 and #2 was at 13.9 inches of hydrostatic head. <br />(all other readings are in feet of hydrostatic head) <br />Inspected the main Cresson mine pit high walls were stable. All the storm <br />water management structures for the area appeared to be in good repair. <br />Inspected the Phase I, II AND III leach pad areas. Storm water management <br />structures around the area had undergone some recent maintenance, and were <br />found in good repair. While in the area, collected the following readings <br />from the High and Low volume pregnant solution collection transducers. <br />Phase I High Volume solution collection transducer read out for # 1 was <br />still not functioning. Operator plans to change the read out meter once <br />they pull and replace the pumps, # 2 was at 51.5 and # 3 was at 49.7.Low <br />volume solution collection transducer # 1 was recorded at .25 and # 2 was <br />at .57. Piezometer for the pond was at 49.7 feet. Phase II High Volume <br />solution collection transducer # 4 was recorded at 37.0 # 5 was at 34.5 and <br /># 6 was at 38.6.Low volume solution collection transducer # 1 was at .14 <br />and # 2 was at .56. Piezometer for the pond was at 38.8 feet (all other <br />readings are in feet of hydrostatic head) <br />Inspected the external pond, it was holding some water which appeared to be <br />partially frozen. While in the area collected the following readings from <br />the low volume solution collection transducers. # 1 was at 11.1 and # 2 was <br />at 12.7 inches of hydrostatic head. <br />Inspected the under drain area, the two lowest ponds were holding a very <br />small amount of partially frozen water. Both the south under drain and 4 <br />inches pipes were discharging. First quarter sample from the under drain <br />will be collected on 2/10/05 <br />
