the Lennox, Wadge, Wolf Creek in the Williams Fork formation (i.e., middle <br />• Mesaverde group), plus the Pinnacle and Blacksmith in the Iles formation (i.e., <br />lower Mesaverde group). <br />Sun Coal has found in field exploration that seams other than those men- <br />tinned above may also be present in such local uniformity as to be mineable. <br />These other seams have been named rider seams. <br />The Lennox seam within the permit area, actually a rider to the Wadge <br />seam, occurring 50 feet above the Wadge, is relatively thin, lenticular, and of <br />moderately high sulfur content. Some local mining of this seam has taken place <br />in the area due to its proximity to the Wadge seam. <br />The Wadge seam is the most consistent in thickness and quality of the <br />upper group coals and is the most commercially exploited of these seams. The <br />• Wadge averages in excess of eight feet and is generally free of partings. <br />The lowermost correlatable seam in the Williams Fork formation, the Wolf <br />Creek seam, is located 150 feet below the Wadge. Uniformity of this seam is not <br />present except at depth and downdip. Outcrop deposits, while having substantial <br />thickness, are severely limited in size. The Wolf Creek seam is of commercial <br />importance, but is generally lower in quality than the Wadge because of seam <br />partings. Average seam thickness is in excess of 16 feet. <br />The uppermost seam in the Iles formation, labeled Upper Rider by Sun Coal, <br />is a rider seam associated with the Pinnacle. The Upper Rider is believed to be <br />correlatable only in the general area of the Sun Coal property. It is located <br />approximately 40 feet-above the Pinnacle, and seam thickness averages 2.5 feet. <br /> Reserves of Upper Rider seam are strictly limited to those areas under which <br />. there are economically recoverable reserves of Pinnacle seam.
