amec,__�l <br />1) Miscellaneous <br />A CAT D -8 dozer and a Hitachi 350 excavator were used to construct access and pole locations <br />preparing relocate the power line within the Mill Site footprint. <br />II) Underground Mine Workings <br />A) Discovery <br />No new Underground Workings were encountered during the week. <br />B) Drilling <br />Confirmatory drilling was performed at Underground Working #4001. A drill pattern was set out by <br />an AMEC field representative. Thirty -eight holes were drilled encountering six voids. An <br />approximate total of 1,900 lineal feet was drilled. As -built survey of the drill holes was performed <br />by Ames. <br />Confirmatory drilling was performed at Underground Working #4007. A drill pattern was set out by <br />an AMEC field representative. Fifty -four holes were drilled encountering twelve voids. An <br />approximate total of 2,700 lineal feet was drilled. As -built survey of the drill holes was performed <br />by Ames. <br />Confirmatory drilling was performed at Underground Working #4068. A drill pattern was set out by <br />an AMEC field representative. Twenty -nine holes were drilled encountering no voids. An <br />approximate total of 1,450 lineal feet was drilled. As -built survey of the drill holes was performed <br />by Ames. <br />Grouting of missed (non -void) confirmatory drill holes was performed at Underground Workings <br />#4007 and #4068. A grout pump and laborers were used to place bentonite grout into the "miss" <br />drill holes. <br />Q Remediation <br />Remediation of Underground Working #4016 continued as the fill progressed in the area. A CAT <br />345 excavator was used to place small lifts of overburden fill into the working and bucket tamp the <br />material. This was performed due the working being too narrow for the CAT 563 vibratory smooth <br />drum compactor to be used for compaction. Remediation will continue as the overburden fill <br />placement progresses in the area. <br />Investigation and remediation of Underground Working #4067 was performed using a CAT 330 <br />excavator to remove the timbers and rail that could possibly be an old narrow gauge rail bridge. <br />The timbers and any unsuitable materials were removed and hauled to a stockpile designated by <br />CC &V. <br />D) Structures <br />No work performed during the week. <br />III) Geosynthetics <br />A) Geomembrane Installation <br />No work performed during the week. <br />B) Anchor Trench <br />No work performed during the week. <br />MEW Weekly Report WE 03.10.2012 <br />
