Collom Area Geology Pre - Feasibility Report <br />3.2 Collom Coal Geology <br />Coal seams of mining interest at Collom occur within the lower portion of the <br />Williams Fork Formation, see Figure 3.1. Approximately 77 individual coal <br />beds are currently recognized within the Colowyo property -wide geologic <br />model. Over 40 individual coal beds are recognized within the vicinity of the <br />Collom Resource Area. <br />In the CMA, approximately 28 coal seams currently exist in the proposed <br />Collom Mine Area. In descending stratigraphic order, the seam planned for <br />mining are as follows: Y25, Y15, X3, X4, Al, A3, B1, B2, B3, C3, C5, D1, D2, <br />D3, E2, F1, F2, F3, F5, F6, F7, FA, FB, G7, G8, G9, GA, and GB. The seams <br />can occur individually or merge into composite units such as the X34, D12, <br />FAB, G789 and GAB. <br />The X34 occurs within the top portions of the ridges at Collom and averages <br />approximately 9 feet thick. The X34 seam remains merged in most of the <br />Collom Resource Area but does split into respective seam components. The <br />X3 and X4 outcrop near the northern extent of proposed mining and <br />constitute a small percentage of the resource in the CMA. <br />The D1 and D2 coal beds are often merged and have a distinctive log <br />signature useful for correlation, due to a thin parting in the D1. The D12 <br />averages approximately 11 feet at Collom. The seam is burned in certain <br />parts of the Collom area, particularly along Collom Gulch and West Fork of <br />)ubb Creek. <br />The parting material between the D1 and D2 was sampled and <br />minerallogically analyzed by the Colorado School of Mines (CSM). The <br />analysis showed that this parting is a volcanic ash layer with clays composed <br />primarily of kaolinite. The results from CSM's analysis were incorporated into <br />the Appendix of the "Geological Summary of the 2004 Collom Exploration <br />August 2005 Page 6 of 38 <br />
