the Ames surveyor. Excavation of the area was performed and it was found to be a shallow surface working. The native material was found to be consistent and no signs of a significant working were found. The working was backfilled with structural fill in 18" to 24" lifts using various CAT dozers. Each lift was moisture conditioned using a tandem axle water truck (when necessary) and compacted using a 10 -ton vibratory smooth drum compactor, passing over the entire fill surface at least 4 times (method compaction technique was applicable). Underground Working #4020 was investigated using a Hitachi 350 excavator and observation was performed by an AMEC field representative. The previously logged location was staked by the Ames surveyor. Signs of a shaft or stope were encountered in the area during the excavation Confirmatory drilling will be performed for this working when a drill is available. Underground Working #4021 was investigated using a Hitachi 350 excavator and observation was performed by an AMEC field representative. The previously logged location was staked by the Ames surveyor.

Underground Working #4023 was investigated using a Hitachi 350 excavator and observation was performed by an AMEC field representative. The previously logged location was staked by the Ames surveyor. Excavation of the area was performed and it was found to be a shallow surface working. The native material below the surface depression was found to be consistent and no signs of a significant working were found. Backfilling of the working will be performed at a later date. The area was bermed off for safety. Underground Working #4024 was investigated using a Hitachi 350 excavator and observation was performed by an AMEC field representative. The previously logged location was staked by the Ames surveyor. Signs of a shaft or stope were encountered in the area during the excavation. Confirmatory drilling will be performed for this working when a drill is available. Underground Working #4025 was investigated using a Hitachi 350 excavator and observation was performed by an AMEC field representative. The previously logged location was staked by the Ames surveyor. Signs of a shaft or stope were encountered in the area during the excavation. Confirmatory drilling will be performed for this working when a drill is available. Underground Working #4026 was investigated using a Hitachi 350 excavator and observation was performed by an AMEC field representative. The previously logged location was staked by MEW Weekly Report WE 01.14.2012
