I <br />0 <br />Slope grading occurred at Bench DD and on the northeastern slope of the PSSA. Materials generated were used <br />as fill at the PSSA toe berm, UG workings 6167 and U6273, and below Dump 4. <br />D8 dozers placed cut to fill near station A5 +00. <br />A Cat D6N GPS dozer was utilized for slope contouring for the Phase 1 Pond and Diversion Channel. <br />See Hwy 67 embankment fill below for additional detail on materials placed. <br />Note: An Amec field representative monitored structural fill material temperatures placed within the areas of fill <br />during all shifts. Average structural fill temperatures were above 32 °F. <br />Clay (SLF) Processing: <br />Cameron Site: Clay processing continued during this reporting period. Approximately, 235,200 tons of soil liner fill <br />material has been produced to date. <br />Squaw Gulch Clay Borrow Site: No overburden or clay mining occurred during this reporting period. <br />Underdrain System: <br />Secondary Underdrain: Approximately, 369 feet of secondary underdrain was installed in Squaw Gulch. <br />Approximate total of 2808 feet of Secondary underdrain has been completed. <br />Primary Underdrain: No work was performed on the Primary underdrain during this reporting period. <br />A total of 1280 feet of Primary underdrain has been completed. <br />Temporary Underdrain: No work was performed on the temporary underdrain during this reporting period. <br />Tree /Slash Clearing, Chipping: <br />Trees were removed along the former Highway 67 roadway near the crib wall then hauled to the area 34 stockpile. <br />B) Underground Workings <br />Exploratory excavation continues in the VLF area. <br />Confirmatory drilling was performed during this reporting period on underground working, No. No 6003, No. U6280. <br />All drill hole locations were established on a 4 -foot center isolating any voids found. Further remediation efforts will <br />be ongoing until remediated. Summary of the remediation efforts will follow 100% remediation. <br />Remediation blasting occurred at UG U6280 and shot rock was removed. <br />Cemented rockfill placement occurred in UG 6268. <br />Coarse shaft backfill was placed in UG 6087. <br />Continued structural fill backfilling occurred at UG No. 6167 and No. U6273. <br />Underground working No 6146, No. 6166, No 06275, No. 6314, No. 6315, No. 6316, and No. 6317 were excavated <br />to competent bedrock, then backfilled and compacted completing the listed working and are considered remediated. <br />Two unknown workings were located during this reporting period; UG U6318 (south of UG 6167) and UG U6332 (in <br />the ADR haul road area near station 23 +00). Both workings are located in areas where cut is required. <br />Remediation planning will follow if needed when the cut is removed. <br />Page 2 of 6 MLE2 WE I t.2.13,doc <br />
