(Page 2) MINE ID # OR PROSPECTING ID #: m-19sn-9aa INSPECTION DATE: 1 .44 8,413 INSPECTOROS INITIALS: RK_ OBSERVATIONS The Division conducted a monthly monitoring inspection of the site on 1/4/10 and on 1/13/10 to verify the underground remediation work along the Phase V leach pad toe dam area. Present during the 1/4/10 inspection was Mr. Mark Vanoni of CC&V. Present during the 1/13/10 inspection were Tom Shepherd, John Luppo and Tim Commer. Inspected the valley leach facility Phases I thru IV the Phase IV PAD area was actively being loaded with ore at the time of the inspection. Collected the following readings from The High and Low Volume Solution Collection transducers for the pregnant ponds, Phase I, II&III and IV. Phase I High Volume solution collection transducer # 1 was recorded at33.8 #2 was at 39.2 and # 3 was at43.7. Low volume transducer # 1 was recorded at .35 and 3 2 was at.34. Piezomter for the pond was recorded at53.6, the true reading of the hydrostatic head for the pond in feet. Phase II and III High Volume solution collection transducer # 4 was recorded at42.2 # 5 was at 41.5 and # 6 was at 41.0. Low volume transducer # 1 was recorded at.17 and # 2 was at .71. Piezomter for the pond was recorded at 43.3 feet. Phase IV high volume solution collection transducer # 7 was recorded at 29.6 # 8 was at 29.1 # 9 was at 29.3 and #10 was at 29.9. Low volume solution collection transducer # 1 was recorded at 13.7 and # 2 was at 10.1 inches of hydrostatic head. Unless otherwise noted, all readings are in feet of hydrostatic head. Inspected the External Pond. It was holding partially frozen water. The following readings were collected from the Low Volume solution collection transducer for the pond. Transducer # 1 was recorded at 13.8 and # 2 was at 12.0 inches of hydrostatic head. Inspected the under drain area. AG 1.5 was dry. All lower ponds were snow packed with little or no frozen water contained. Both the south and AG-1( 4 INCH PIPE) were discharging at the time of the inspection. All the discharge from the under drain is pumped back onto the pad. On 1/13/10, with Dr. John Luppo, and Tom Shepherd present , observed the blast for the underground remediation( Thomson Shaft) for Phase V leach pad. It was agreed after the blast that the shaft will be backfilled utilizing a concrete back fill structure rather than rock back fill as was the case with the Tornado shaft backfill, where the current LOB is located. Given the critical location of the shaft, the Division concurred, that proper way to remediate this shaft. Erath moving work was continuing along the Old Arequa waste storage area that will be utilized as Phase V leach pad. Storm water drainage control was found to be in good repair.
