• j <br /> June 1997 Monthly Report <br /> Page 3 <br /> Planned activity for July is the completion of contact <br /> grouting, valve closure, pipe grouting, demobilization with <br /> permanent portal closure and reclamation. <br /> Progress pictures of the bulkhead are included with this <br /> report. <br /> Longfellow - Koehler Mine Waste Project <br /> No on-site remediation work was done at this site in June. By <br /> month-end, snow-cover across the site was starting to clear. <br /> Site monitoring samples were taken on June 2, 1997 but results <br /> had not been received by the date of this report. They will <br /> be submitted with the July report. <br /> Bio-mass feasibility bench testing continued throughout the <br /> month. No results from the bench testing have been received <br /> although discharge water from the test columns has been sent <br /> out for analysis. <br /> Planned activity for July consists of additional site <br /> monitoring and collection of additional water from the Koehler <br /> and Longfellow portals for continuation of the bio-mass bench <br /> tests. <br /> Progress pictures of the site taken in June are included with <br /> this report. <br /> London Mine Portals - Waste Dumps <br /> This is a "B List" project. Therefore, no work, permitting or <br /> arrangement for access is planned until it becomes evident <br /> that the work plan for this project requires implementation. <br /> Pride of the West Tailings <br /> This project was active throughout the month of June. A total <br /> of 23, 892 cubic yards were excavated and hauled to the on-site <br /> tailings pond (18,467 cubic yards) or to Sunnyside's Tailings <br /> Pond No. 4 (5425 cubic yards) . A total of 107. 5 tons of <br /> alkaline material (quick-lime kiln dust) was received to add <br /> to the excavated tailings upon placement in the on-site <br /> tailings pond and Tailings Pond #4 . <br /> A geotechnical firm (Western Technologies) was retained to <br /> perform a stability analysis and slope recommendations for the <br /> embankments to be left upon project completion. This study <br /> was undertaken because of site conditions discovered after <br /> mobilization. A recommendation report is expected in July. <br /> Site progress pictures are included with this report. <br />
