<br />2 <br />from strata that can be found at depth beneath the proposed lease area. <br />Two Federal oil and gas leases exist on the applied for area, C-37363 and <br />C-41356. There has been no drilling to date on these leases. <br />Alluvium and colluvium, and other saleable mineral deposits can be found on <br />the applied for lands in minor amounts. These deposits are probably not <br />economic, but would not be disturbed by underground mining. <br />Low grade uranium deposits occur in the general area, however, no mining <br />claims have been located in the lease tract for uranium or any other <br />locatable mineral. <br />Coal Quality and Reserves <br />The D seam underground mineable coal is ranked as high volatile C <br />bituminous using the "Parr Formula" or horder line between subbituminous A <br />and volatile C bituminous using ASTM Standard D-3R8-77. Proximate analyses <br />range as follows: <br />Moisture (wt %) 6.76 - 16.29 <br />Ash (wt %) 6.74 - 19.97 <br />Sulfur (wt %) 0.29 - 0.61 <br />Volatile Matter (wt %) 29.76 - 36.23 <br />Fixed Carbon (wt %) 39.64 - 49.13 <br />Heating Value (Btu/lb) 9,170 - 11,060 <br />The reserve figures were both supplied by Western Fuels-Utah, Inc. and <br />calculated by the staff of this office. The total in-place reserve figure <br />was calculated by a staff geologist; mineable and recoverable reserves were <br />calculated by a staff mining engineer. The BLM estimates agreed very <br />closely with the company supplied estimates; therefore, we recommend that <br />the company's reserve figures he used. It should he noted that the <br />addition of half a lot does not affect the mineable and recoverable reserve <br />estimates, due to the fact that the area contains no mineable coal because <br />of the split present. Also note that Western Fuels-Utah, Inc. pays <br />royalties on processed clean coal and not on coal recovered; therefore, the <br />important tonnage figure is the clean coal figure.
