I <br />Mike Boulay <br />MCM: Comment noted. <br />Rule 2.04.6 Geology Description <br />5. There is a typographical error on page 2.04 -11. In the first paragraph the <br />reference to 30 CR 783 should be changed to read 30 CFR 783. <br />MCM: Please see revised page 2.04 -11. <br />6. On page 2.04 -13 there is a typographical error. In the second sentence of the <br />first paragraph "dept of the coal seam" should be changed to "depth of the <br />coal seam ". <br />MCM: Please see revised page 2.04 -13. <br />October 16, 2012 <br />7. Many of the important geologic maps were not updated to reflect the lease <br />modification and expansion of the permit area proposed with PR -2. Please <br />revise and update figures 2.1 -5, 2.1 -6, 2.1 -7, 2.1 -8, and 2.1 -9 with the <br />additional required information for the permit expansion area. Also, on <br />Figure 2.1 -8 of the PR -02 submittal, please add the topographic contours <br />and the mine plan sequence for comparison purposes so that the <br />overburden thickness relative to proposed underground workings can be <br />accurately determined. <br />MCM: Please see newly digitized Figure 2.1 -8 showing the topographic contours and <br />the mine plan sequence. Figure 2.1 -7 has been digitized. Figure 2.1 -5 shows <br />the thickness of the total mineable cameo seam. Figure 2.1 -6 shows the <br />thickness of the upper cameo seam. Figure 2.1 -9 has been revised and shows <br />structure contour map on base of lower and total cameo seam. Please note, all <br />new digitized figures are based on more current geologic information and <br />therefore may be slightly different than the current permit maps. <br />8. Table 2.1 -3 Surface Drilling Results needs to be updated with all pertinent <br />drill hole information for the McClane Canyon Mine. For example, there are <br />drill holes shown on Figure 2.1 -3 Cameo Seam Outcrop & Drill hole Index Map <br />that are not in Table 2.1 -3. <br />MCM: Please see revised Table 2.1 -3. <br />9. Figure 2.5 -1, Surface Geology needs to be updated with additional required <br />information for the permit expansion area. In accordance with 2.04.6 (3)(a)(ii) <br />please provide a geologic map with geologic cross sections of the <br />proposed permit area, including coal crop lines and the strike and dip of <br />
