Mr. J. Paul Storrs, Area Mining Suprevisor June 17, 1977 <br />United States Department of the Interior <br />Geological Survey <br />~. <br />The Palisade seam, where it coalesces in a solid band, <br />averages 1.72 ft. thick. This is presently an unminable <br />thickness. No quality data on this thin seam is available, <br />and the bed is substantially thinner than 9 ft., so this bed <br />is not outlined on a map, It is shown on the Geologic Section <br />A.T.M.P. 103 and on the Correlation Diagram. <br />Thickness of coal seams was primarily taken from analyzed <br />core sections. The average of the Cameo was 17.42 ft., however, <br />since some splits occur, a minable thickness of 11 ft. was <br />used in reserve calculations. <br />The Anchor averaged 5.56 ft. from the analyzed cores. <br />In the accessible wagon mines, the Anchor was thicker, up q <br />to 7 ft. Since a wash plant is planned, it is felt the full <br />seam can be mined and the bony portions at the top and bottom <br />will contribute 6 inches to 12 inches of additional coal. We, <br />therefore, used a 6 ft. average. Driving the development <br />entries will determine the true minable thickness. <br />We have commenced roads and preparation of outcrop entry <br />sites on the Anchor and Cameo seams on the fee land we control <br />as per our mine plan submitted February 24, 1977. <br />We expect to continue with dispatch and look forward to <br />early granting of the preference right leases and approval of <br />the mine plan so the Anchor-Tresner coal mine unit can be <br />promptly placed in p~ition to produce coal efficiently and <br />at full capacity. ' <br />We ,are pleased to know that the data we have submitted is <br />sufficient for the initial showing for preference right leases. <br />Sincerely, <br />AGH/dh <br />Enclosures <br />cc: Gerald Tresner <br />James Dunn <br />Donald E.
