L~ <br />3.3.5 1.1 Seam The sequence of rocks overlying the G Seam is characterized by numerous thin, <br />• discontinuous lenses of coal and carbonaceous shale interbedded with sittstone and thin, occasion- <br />ally calcareous sandstones. The interval ranges from about 15 to 50 feet in thickness. The top of <br />this zone is marked by the H Seam. However, the minable thickness of coal occurs in isolated <br />pockets not amenable to subsurface mining. <br />' 3.3.6 J Seam Above the H Seam, the stratigraphy is typified by an increasing abundance of <br />coarser grained non-coal bearing sediments. Thick sandstones are prevalent with only occasional <br />occurrences of thin coal lenses. The J coal seam is particularly conspicuous as a thin but <br />continuous seam sandwiched between thick sandstone units. It essentially marks the contact <br />' between the Upper and Lower Williams Fork Formations. The J Seam has no mining potential. <br />Isolated occurrences of minable coal thickness of limited areal extent are found in the Deserado <br />Mine area. <br />' 3.4 Other Minerals <br />' Oil and gas exploration (seismic surveys) has been conducted in the Deserado Mine area. The <br />results of these surveys or the potential for recoverable oil and gas reserves in the Deserado Mine <br />' area are unknown. In addition, uranium prospectors have staked Gaims in the general area; <br />however, the value or potential of the uranium prospects is unknown. Blue Mountain Energy is <br />unaware of any other potential economical mineral deposits in the mine area. <br /> <br /> <br /> <br />1 <br /> <br /> <br />1 <br />,• 13 <br /> <br />
