ameO <br />Earth & Environmental <br />Contouring was performed using various CAT dozers and CAT excavators. Material generated <br />as the cut progressed was pushed down the slope. <br />E) Overburden to Stockpile <br />1) VLF <br />No work performed during the week. <br />F) Cut to Fill <br />1) VLF <br />Snow from the weekend snowfall was removed from all fill areas prior to any placement. Prior <br />to structural fill placement, existing fill temperature were monitored and to be or above 37°F. <br />Ambient were monitored on an hourly basis, by an AMEC representative during fill placement. <br />Fill temperatures averaged approximately 46 °F during the period of time the ambient <br />temperature was below 32 °F. No fill material was placed on 10/28/2009 and 10/29/2009. <br />Structural fill (processed ore) was placed within the Phase IV VLF, between stations G16 +00 <br />( + / -) and G30 +00 ( + / -), approximately 75 to 150 feet left of centerline. Fill material (processed <br />ore) was excavated from the Phase IVa and Phase IVc recertification areas using a CAT 375 <br />excavator loading the material into 40 -ton articulating haul trucks. Structural fill was placed <br />using a CAT D -8 dozer in 12" loose lifts and moisture conditioned as needed using a CAT 773 <br />water truck. Compaction was achieved using a 10 -ton vibratory smooth drum compactor. <br />Nuclear density testing was performed with results averaging 95% of maximum dry density. <br />Moisture density relations were obtained in accordance with ASTM D698 -07. <br />Backfilling of the area were the 84" culvert was removed was performed using a CAT 345 <br />excavator. Material excavated during culvert removal was placed in the area and compacted <br />using a walk- behind sheep's foot compactor. Lift sizes were generally 8" to 12" and were <br />moisture conditioned using a CAT 733 water truck, when necessary. <br />Blast pattern drilling was performed in the following areas: between stations E15 +00 ( + / -) and <br />E 18 +00 ( + / -), approximately 75 to 150 feet left of centerline: between stations H 10 +00 ( + / -) <br />and H11 +50 ( + / -), approximately 0 to 75 feet right of centerline; and between stations J28 +50 <br />( + / -) and J29 +50 ( + / -), approximately 50 to 100 feet right of centerline using three track <br />mounted drill rigs. Blasting was performed in these areas Monday (10/26/2009), Tuesday <br />(10/27/2009), and Wednesday (10/28/2009). <br />G) Material Processing <br />1) South Cresson Clay Processing Area <br />Processing of Soil Liner Fill material was paused for the entire week. <br />Location <br />This Week <br />tons <br />Cumulative <br />tons <br />Comments <br />So Cresson Clay Processing <br />0 <br />112,770 <br />Squaw Gulch Processing <br />0 <br />35,816 <br />Processing in area complete. <br />Total <br />0 <br />144,678 <br />VLF Weekly Report WE 10.31.09.D.doc <br />
