Chemical analysis parameters utilized to evaluate roof and floor materials <br />are summarized by Table 5, Roof/ Floor Analysis Parameters. The areal <br />sampling density for evaluation of roof and floor materials was one (1) <br />core hole per 2500 feet north to south. Roof and floor samples were <br />analyzed for a total of 8 coreholes for the following seams: <br />Jack O'Lantern 6 roof and floor locations <br />Red Arrow 4 roof and floor locations <br />These 8 coreholes yielded 20 individual samples which were analyzed for <br />all or part of the parameters listed in Table 5, Roof/Floor Analysis <br />Parameters. These coreholes, sampling intervals and the type of sample <br />(roof or floor) utilized in the analyses are summarized by Table 6, List <br />of coreholes Sampled for Roof/Floor Analyses. Locations of the <br />.corresponding drillholes are shown on the Mine Area Geology Map, (Map 8), <br />and geologic logs for these holes are included in Exhibit 8, Geologic <br />Information. <br />A total of 20 Southfield roof/ floor samples were analyzed for the <br />following parameters: <br />pH <br />Electrical Conductivity <br />SAR <br />Phosphorus <br />Potassium <br />Total Sulfur. <br />Sulfur Forms <br />These analyses were distributed as follows: <br />6 Jack O'Lantern roof samples. <br />6 Jack O'Lantern floor samples <br />4 Red Arrow roof samples <br />4 Red Arrow floor samples <br />
