• Geologic maps illustrating the Sudduth Coal structure, overburden and thickness within and adjacent to Pit 1 are enclosed as Exhibits C-SA, C-6A, and C-7A, respectively, at the end of this Appendix. Coal Analyses. The quality of the Sudduth Coal Seam in the vicinity of Pit 1 has been established by U.S. Geological Survey core holes, Wyoming Fuel Company core holes, and by extensive sampling of coal shipped from the Canadian Strip Mine. Table 2 is a summary of coal analyses for the Sudduth Seam from U.S.G.S. Hole J6B, Wyoming Fuel Company Hole lA, a U.S.G.S. channel sample from the Canadian Strip Mine and representative mine run analyses taken by Consolidation Coal Company and Wyoming Fuel Company from the coal shipped. The proximate analyses listed are on the "as received" basis and include precent moisture, percent ash, percent volatile matter, percent fixed carbon, BTU per pound and the percent sulfur. • Analyses of the sulfur forms are also included to designate the percentages of pyritic, sulfate and organic sulfur in the total. Since Marcasite is a dimorph or pyrite (Fe52) and is chemically equivalent, it is included in the pyritic fraction of the total sulfur. A separate breakdown of the marcasite content can only be accomplished through petrographic examination. Because the compound is chemically equivalent to pyrite, such analysis is not considered necessary since the pyritic component as well as the total sulfur percentage is so minimal. Overburden Characteristics Hole 1, drilled by Wyoming Fuel Company was selected as the location for overburden sampling because it is approximately near the center of the lease area and it was drilled to a depth well below the bottom of the Sudduth Coal Seam.
