Cripple Creek & Victor Gold Mining Company <br />Squaw Gulch VLF Phase 1 <br />(9,550-foot Elevation Bench to Geomembrane Panel P1635) <br />Final Report <br />Quality Assurance Monitoring & Test Results <br />January 2016 <br />Project No.: 74201125N0 Page 15 <br /> Grain Size Distribution <br />Amec Foster Wheeler analyzed the grain size distribution (gradation) of SF, SSF, leak <br />detection fill (LDF), UF, SLF, and DCF. The results of the gradation analyses are <br />presented in Appendix H.1 and summarized in Tables 5 through 10. <br />Amec Foster Wheeler performed nine CQA gradations of SF. The actual testing <br />frequency (approximately one test per 7,639 cubic yards) exceeded the minimum <br />specified testing frequency of one test per 50,000 cubic yards. The SF CQA gradation <br />results met the project technical specifications; the results are presented in <br />Appendix H.1 and summarized in Table 5. <br />Amec Foster Wheeler performed one CQA gradation of SSF. The actual testing <br />frequency (approximately one test per 205 cubic yards) exceeded the minimum <br />specified testing frequency of one test per 50,000 cubic yards. The SSF CQA gradation <br />results met the project technical specifications; the results are presented in <br />Appendix H.1 and summarized in Table 6. <br />Amec Foster Wheeler performed one CQA gradation of LDF. The actual testing <br />frequency (approximately one test per 120 cubic yards) exceeded the minimum <br />specified testing frequency of one test per 10,000 cubic yards. The engineer approved <br />Ames’ request to use LVSCF in lieu of LDF, however the sample was still called LDF. <br />The LDF CQA gradation results met the project technical specifications; the results are <br />presented in Appendix H.1 and summarized in Table 7. <br />Amec Foster Wheeler performed one CQA gradation of UF. The actual testing frequency <br />(approximately one test per 817 cubic yards) exceeded the minimum specified testing <br />frequency of one test per 5,000 cubic yards. The UF CQA gradation results met the <br />project technical specifications; the results are presented in Appendix H.1 and <br />summarized in Table 8. <br />Amec Foster Wheeler performed 34 CQA gradations of SLF. The actual testing <br />frequency (approximately one test per 3,483 cubic yards) exceeded the minimum <br />specified testing frequency of one test per 4,000 cubic yards. The SLF CQA gradation <br />results met the project technical specifications; the results are presented in <br />Appendix H.1 and summarized in Table 9. <br />Amec Foster Wheeler performed 12 CQA gradations of DCF. The actual testing <br />frequency (approximately one test per 19,734 cubic yards) exceeded the minimum <br />specified testing frequency of one test per 20,000 cubic yards. The DCF CQA gradation <br />results met the project technical specifications; the results are presented in <br />Appendix H.1 and summarized in Table 10.
