Collom Area Geology Pre - Feasibility Report <br />7.0 Correlation, Geological Database and Geological Modeling <br />7.1 Seam Correlation <br />Upon the conclusion of the 2004 Exploration Program, the Collom Exploration <br />Team correlated the newly acquired drill hole data with respect to existing <br />seam correlations. This was a significant body of work because few of the <br />pre- existing drill holes in the CMA penetrated seams below the "GABC" <br />series. Therefore, correlation of the seams below the °GABC" required more <br />effort than the seams above. <br />The Collom Exploration team prepared cross - sections using the geophysical <br />logs of all available drill holes to guide the correlation. Changes to <br />correlations were noted on drill hole printouts and then updated in the drill <br />hole database. <br />The Collom Exploration Team tied the seam correlations from the Collom <br />Area on the west side of Wilson Creek to the Colowyo mine area on the east <br />side of Wilson Creek. The Collom exploration team also tied the correlations <br />to additional drilling data located west of the CMA. <br />Most of the pre -2004 drill hole data did not contain any lithological data other <br />than coal and undifferentiated stone. Therefore, during the correlation <br />process, the Collom Exploration team reviewed the geophysical logs of the <br />older data and logged primary sand bodies, depths of weathering and burned <br />zones of all the drill hole data west of Wilson Creek. These items were also <br />noted on drill hole printouts and added to the drill hole database. <br />As part of the correlation process, the Collom Exploration Team reviewed the <br />extent of each seam with respect to burn limits. Using the results of the <br />2004 drill data and aerial images, the Collom Exploration team updated the <br />burn lines extents for each seam. These extents were then transferred to <br />August 2005 Page 25 of 38 <br />
