<br />note at the bottom should read Map No. 11, Premining Topography. <br />4. CYCC is proposing to use fill material in the proposed permanent <br />ponds. There is no mention of the fill material or a materials balance <br />including the impoundments in the previous section. <br />RESPONSE: <br />To calculate the overburden quantity required to backfill the <br />portal pit at Mine 3, two steps were taken. The first step was to <br />design a post-mining topography that would be stable and secondly, <br />calculate the cubic yards of material needed to acheive the final <br />contour. <br />Cross-sections were run through the tw overburden stockpiles <br />from which the backfill material would be taken. A total quantity <br />of 986,000 cubic yards was calculated to be contained in the two <br />piles. The post-mining topography was constructed using this <br />quantity. The general plan for the topography was to begin a <br />gradual elope at the county road to the vest and carry it through to <br />the Middle Creek drainage to the east. A 6:1 (N:V) slope begins at <br />the county road and continues until it intersects a 1Z elope rising <br />from the drainage. This scheme provides for positive drainage <br />across the area and contains no steep slopes which mould be <br />susceptible to erosion. To complete the final topography, a small <br />area along the east side of the county road will be cut down to <br />remove the hump and give the area a smoother appearance. <br />-38- <br />
