Addendum to the Collom Area Geology Pre - Feasibility Report <br />• HGC cross - referenced the coal quality depths to the lithology depths and <br />added seam name designations to the quality data based on lithological <br />correlations. HGC exported the coal quality data from the database and <br />loaded into MineScape for geological modeling. <br />HGC modeled quality parameters of: total moisture, equilibrium moisture, <br />ash, Btu/1b, sulfur, ash fusion (reducing hemispherical), apparent specific <br />gravity (ASG), sodium and mercury. HGC used the coal quality modeling <br />tools in MineScape to build the coal quality model. <br />The final coal quality model exists as gridded surfaces over the full Colowyo <br />model extent using a grid cell size of 200 feet. HGC model the coal quality on <br />a dry basis. <br />n <br />U <br />• <br />September 2006 Page 12 of 25 <br />
