ORIGINAL -PUBLIC FILE <br />(Page 2j <br />MINE ID # OR PROSPECTING ID #: ti+-Ies;n-vad <br />INSPECTION DATE: 9/v7/O.S INSPECTOROS INITIALS: _~_ <br />O$SERVATION <br />The Division conducted a monitoring inspection of the site while in the area, meeting with Dr. John Lupo of <br />Golder and associates and CC&V representatives about the permanent recommendation to enhance the <br />flow around the Phase IVC area prior to the loading of ore. As reported in the last inspection, the area had <br />reported a spill due to some constriction of solution flow in the interface ditch area. At that time it was <br />concluded that the flow constriction was due to unusual compaction of the drain cover fill in the area. Even <br />with grades exceeding b%, the flow constriction was noted. The meeting was held on site, Dr. John Lupo <br />explained using the as built diagrams what would be needed to be in place as a permanent fix, so the area will <br />flow unrestricted when the ore is loaded up-gradient of the constriction area. The following were agreed upon <br />on site. <br />1 j CC&V will place 250 feet of 6 inch pipe to route solution in this area and the down gradient portion of the <br />pipe will point away from the ditch, towards the pad. The ditch will have an inlet control structure be it gravel or <br />other material to channel the flow to the pipe. <br />2) The portion of the pad that is not already loaded will have solution application pipes tied to the tertiary line <br />located approximately 35 to fifty feet away from the interface ditch area, In other words when the pad is <br />loaded in this area, the solution instead of collecting in the interface ditch area, will instead report to the <br />tertiary solution application pipes away from the ditch. Since there is only two feet of drain cover in the area, to <br />tie it in to the tertiary line should be a simple task. <br />3) No ore will be loaded in that area until the permanent fix outlined above is certified by Golder and <br />Associates and submitted to DMG and written approval is granted. <br />After the meeting the site was inspected. The area had received measurable rainfall the night before. <br />Inspected the Main, East and South Cresson area. The South Cresson area in anticipation of mining area <br />expansion, topsoil was being removed. Storm water diversion structures for the area were in good repair. <br />Inspected the Iron Clad Globe Hill areas, most of the used tires have been removed from the bon yard area. <br />Inspected the Portland pit area, top soil application is completed and seeding will commence this fall. <br />Inspected the Phase I, II, II AND IV leach pad areas and collected the following readings from the High and <br />Low Volume solution collection transducers. <br />Phase I high volume solution collection transducer # 2 was recorded at 52.7 and # 3 was at 53.7 Piezometer for <br />the pond was recorded at 52.3 feet. Low volume transducer # 1 was recorded at <br />Phase II AND III High Volume Solution Collection transducer # 4 was recorded at 38.4, # 5 was recorded at 36.2 <br />and #b was at 41.1. Piezometer for the pond was recorded at 45.2 feet. Low Volume transducer # 1 was <br />recorded at .20 and # 2 was at .44. <br />Phase IV High Volume solution collection transducer # 7 was recorded at 39.9, # 8 was ai 39.0, # 9 was at 42.0 <br />and # 10 was at 42.4. Low Volume solution collection transducer # 1 was at 14.4 and # 2 was at 12.3 inches of <br />hydrostatic head. (ALL OTHER TRANSDUCER READINGS ARE IN FEET OF HYDROSTATIC HEAD UNLESS NOTED) <br />Inspected the External pond, it was holding water from recent rain. Low volume transducer # 1 was recorded <br />of 13.4 and # 2 was at 10.9 inches of hydrostatic head. Inspected the under drain, both the four inch pipe and <br />the south under drain were discharging. All the lower ponds were dry. <br />
