ANA <br />ame <br />Earth 8 Environmental <br />over the entire surface a minimum of four passes. Ambient temperatures were observed <br />throughout the shift. No frozen fill was placed. <br />2) LOB Conveyor Corridor/Transfer Station <br />Structural fill placement and site grading was completed for the Conveyor 2 Corridor. <br />Structural fill material was hauled from the LOB Delivery Road cut using 40-ton articulating <br />haul trucks and spread in 18" to 24" lifts (depending on rock size) using a CAT D-6 dozer. <br />Compaction was performed using a CAT 563 vibratory smooth drum roller passing over the <br />entire surface of each lift a minimum of 4-passes. This process was performed in accordance <br />with the method specification and a previously established test fill. Ambient temperatures <br />were observed during fill placement. No frozen fill was placed. <br />Site grading and minor Structural Fill was completed at Transfer Station #6 pad using one <br />CAT D-6 dozer. Compaction was performed using a CAT 563 vibratory smooth drum roller <br />passing over the entire surface of each lift a minimum of 4-passes. Ambient temperatures were <br />observed throughout the shift. No frozen fill was placed. <br />C) LOB Pad Structural Fill <br />Structural Fill from the LOB Delivery Road cut between stations 29+00 (+/-) and 23+00 (+/-) <br />was placed on the LOB Pad using articulating 40-ton haul trucks. Structural Fill was placed in <br />18" to 24" lifts (based on rock size). Field observations indicate there is greater than 30% rock <br />retained on the 1/4 -inch sieve. Moisture conditioning of the fill was performed using a CAT <br />773 water truck. Each lift was compacted with a smooth drum vibratory roller a minimum of 4- <br />passes over the entire surface as per the method compaction technique. Fill placement was <br />completed to elevation 10,055 (+/-) for the planned LOB footings. Additional structural fill <br />was placed, moisture conditioned and compacted around the perimeter of the LOB nearing <br />grade elevation of 10,060. Ambient temperatures were observed throughout the shift. No <br />frozen fill was placed. <br />D) MSE Walls <br />1) MSE Wall <br />No work performed during the week <br />E) Miscellaneous <br />No work performed during the week. <br />II) Underground Working <br />A) Drilling <br />No work performed during the week. <br />B) Mine Shaft/Stope Remediation <br />Underground working 2036, and 2040 located within the planned LOB Conveyor Transfer Station <br />#5: The shaft and slope was exposed for inspection. Work is planned to start next week as per the <br />Remediation Plan, Conveyor Pad No. 5-Shaft 2036, Dated 7 April 2009. <br />Sheet 2 of 8 <br />LOB Weekly Report WE 05.16.09.D.doc
