Box 191 <br />2755 State Highway 67 <br />Victor, Colorado 80860 <br />Attention: Mr. Ron Roberts <br />RE: ROCK DRAIN NEAR THE PHASE IVB SUMP <br />Dear Ron: <br />A.SSOC1c1feS <br />Our Ref: 003-2203 <br />Golder Associates Inc. has prepared this letter for the Cripple Creek & Victor Gold Mining Company <br />(CC&V) documenting the construction of a rock drain within the Phase Nb PSSA sump. <br />On October 19, 2002 Ames Construction, Inc. (Ames) was directed to install a rock drain near the <br />Phase IVb PSSA sump to drain an intermittent seep. Ames excavated a 3' wide by 2' deep by 40' <br />long subgrade trench along the 2H:1V slope just above the PSSA sump area. The trench was <br />connected to a 14' deep by 4' squaze sump (see Figure 1, attached). The ffench and sump were <br />backfilled with Underdrain Fill (UF). The trench and sump were then covered with approximately 1' <br />of compacted Structural Fill (SF). <br />Golder observed construction of the rock drain. Ames excavated the ffench and sump, and placed OF <br />and SF in accordance to the Certifying Engineers' requirements. <br />Golder appreciates the opportunity to provide ongoing CQA services for the Cresson Project. Please <br />contact the undersigned with any questions. <br />Sincerely, <br />GOLDER ASSOCIATES INC. <br />--~~ <br />ohn F.
