Collom Area Geology Pre - Feasibility Report <br />3.6 Structural Geology <br />The CMA is situated on the southern limb of the asymmetrical Collom <br />Syncline, see Figure 3.2. The Collom Syncline is located north of the Wilson <br />Dome. To the east, the south flank of the Collom Syncline begins dipping to <br />the west due to the influence of the Morgan Syncline. <br />Coal beds within the CMA typically dip between 3.50 to 8.50 (6% to 15% <br />averaging 9.5% to 10 %) to the northeast with typical strike of N66 0W. In <br />general, coal seams dips are greater at the southern end of the CMA than the <br />northern end. This increase in dip appears to be related to increased <br />thicknesses of paleochannel sandstones along the southern portion of the <br />CMA. <br />Two prevalent nearly vertical joint sets have been observed across the CMA. <br />The primary joint set strikes between N55 0W and N60 0W. The secondary <br />joint set strikes about N19 °E. <br />The conspicuous straight gulches intersecting the CMA have been an item of <br />debate for many years. On the surface, these gulches appear to be fault <br />controlled. However, structure contours from the geological model do not <br />show any displacement related to the gulches. Additionally, during the 2004 <br />Exploration Program holes were drilled in the centers of Collom Gulch, Little <br />Collom Gulch and West Fork of Jubb Creek. These holes did not exhibit any <br />higher frequency of fractures or weaker rock relative to other drill hole data <br />in the CMA. <br />To date, no faults have been identified within the CMA. Faults have been <br />identified north of the CMA in Morgan Gulch near the axis of the Collom <br />Syncline. Another fault occurs in Chokecherry Gulch south and west of the <br />CMA. <br />August 2005 Page 10 of 38 <br />
