Phase IV Weekly Summary No. 34 Page 2 003-2203 material to a stockpile where a Caterpillaz 375 track hoe loaded several 777 haul trucks. The material was then hauled to the Arequa Gulch fill azea. • Ames performed SF placement and compaction activities in the northern portion of the Phase Na footprint, in the Arequa gulch azea. Caterpillaz 777 haul trucks brought SF material from the cut azea (mentioned above), while a Caterpillaz D8 placed and spread the material into loose lifts not exceeding 2 feet in thickness. Oversize material within the fill was removed by the dozer and placed in the uncontrolled areas located northeast of the fill. A Caterpillar CS563C roller provided compactive effort, while a Caterpillar water wagon provided moisture conditioning when needed or required. Ames performed blast drilling activities on Friday, September 28`s, and Saturday, September 29~', in the central portion of the Phase IVa azea. No blasting occurred during this reporting period. Rhase IVb Ames continued and completed placement of Drain Cover Fill (DCF) by September 25`s within the limits of the LOB construction azea. DCF was hauled to the LOB azea by use of Caterpillar 777 haul trucks and placed with a CAT D6M. Ames began and completed placement and compaction of SF ramps in the area of the LOB. Material was hauled by use of several Caterpillar 777 trucks, placed and spread by a Caterpillaz D8 dozer and compacted in lifts not exceeding 2 feet in loose thickness by a Caterpillar CS563 roller. • Ames began placement of Compacted Ore Fill (COF) within the limits of the LOB construction area. The material was brought in by Caterpillar 777 haul trucks, spread by Caterpillar D7 and D8 dozers into loose lifts approximately 1 foot in thickness, and compacted by a Caterpillar CS563 roller (Minimum of 8 passes). A Caterpillar water wagon provided moisture conditioning of the material when needed. Ames began and completed confirmation drilling of UG-238 and UG-251 within the limits of the Phase IVb construction area. No workings were located. Phase IVc Ames continued and completed confirmation drilling at UG-242. No workings were located. Ames did not perform any cut or fill activities within the Phase IVc azeas during this reporting period. (See Attachment A for approximate construction locations for all Phase IV azeas.)
