July 1997 Monthly Report <br /> Page 2 <br /> Surface Mill Tailings at Eureka <br /> Activity at this site in July included site neutralization <br /> with limestone, minor site grading, erosion protection for a <br /> portion of the Eureka Creek bank, site planting of grass, <br /> shrubs and trees, and the removal of trash from the site. <br /> Sunnyside considers this project complete according to the <br /> work plan and an inspection was requested in July to determine <br /> if DMG and WQCD concur with this assessment. <br /> - Gold Prince - Mill Tailings <br /> Mobilization for this project was started in late July. Snow <br /> was removed from the portal and preparations made to begin <br /> installation of the portal seal. Sediment controls were <br /> installed in preparation for project implementation in August. <br /> Planned activity at this site for August includes installation <br /> of the portal seal and begin consolidation of the mine waste <br /> and tailings on the site according to the work plan. <br /> Site monitoring samples were taken in July. <br /> - Ransom Tunnel <br /> Sunnyside completed this project in July. Activity consisted <br /> of completion of contact grouting, valve closure, diversion <br /> pipe grouting, portal backfilling and closure, reclamation of <br /> portal excavation by contouring to blend with surrounding <br /> contours and slopes, site-cleanup and equipment <br /> demobilization. <br /> Bulkhead concrete test cylinder compressive strength results <br /> (28 day +) averaged 6040 psi over 4 samples. This exceeds the <br /> 3000 psi design strength. <br /> Sunnyside considers this remediation project complete <br /> according to the work plan and has requested an inspection to <br /> determine if DMG and WQCD concur. <br /> - Longfellow - Koehler Mine Waste Project <br /> No on-site remediation work was done at this site in July. <br /> Results from June site monitoring samples are submitted with <br /> this report. Additional site monitoring samples were taken in <br /> July but results were not received by the date of this report. <br /> They will be included with the August report. <br /> Additional water was collected from the Longfellow and Koehler <br /> portal drainages for continuation of the bio-mass feasibility <br /> bench tests. <br />
