CLASSIFICATION OF COAL RESOURCES IN LEASE APPLICATION AREA C-29125--Two minable <br />_ coal beds underlie the application area, as follows: <br />~~ - <br />Bed 1 (Upper Henefee seam) ranges from about S.S to over 6 feet thick is <br />~ the coal haulageway of the King Coal Nine adjoining the northern boundary <br />of the application area. An ration hole drilled in 1928 by the <br />Calumet Fuel Company in th N~1kSUi~ sec 35~ N., R. 11 iJ., located - <br />approximately 650 feet eas a lease application oundary pine <br />Gulch, reported 7 feet of coal at this horizon.. <br />Coal bed 1 is known within k-mile of the application land in Calumet <br />drill-hole 2, and in mine workings of the King Coal lease along the entire <br />northern boundary of the application area. These data points place the en- <br />tire application area within a radius of ~-mile from known coal measurements <br />of coal bed 1. Coal bed 1 falls within the coal classification standards <br />(U.S. Geological Survey Bull. 1450-B) for "measured" coal in the north half <br />of the application area, and the criteria for "indicated" coal reserves in <br />the southern half of the 120-acre lease application area. <br />Coal bed 2 measurements are known from the Barnwell No. 2 Hine, and drill- <br />hole NKC in the ~~~kNWSt sec. 32, T. 35 N., R. 11 p (figs. 1 and 3). <br />The NKC drill hole is located appzoximately 300 feet north of the north <br />- boundary line of the application area. These data points place the entire <br />application area within a ~-mile-wide belt, and within 3-4 mile of a known <br />coal measurement on coal bed 2. Coal bed 2 meets coal classification <br />standards for "measured" coal under approximately 33 acres in the northern <br />part. of the application area, and standards for "indicated" coal in the <br />balance of the application area. <br />ESTIMATED RESERVE BASE CALCULATIONS IN LEASE APPLICAT O - <br />I N AREA -For reserve <br />base estimates, coal bed 1 is considered to average 5.8 feet thick and underlie <br />the entire 120 acres of the application area at depths ranging from about 50 <br />feet below the surface in Pine Gulch to about 300 feet below the surface on the <br />divide beteeen Pine Gulch and Hay Gulch. <br />The total amount of coal underlying the application area in coal bed 1 (upper <br />?lenefee seam) is calculated at 1,252,800 tons of "measured" and "indicated" coal <br />reserves, or 657,720 tons of "measured" coal, and 595,080 tons of "indicated" <br />coal. <br />120 ac x S.$ ft x 1 800 t- on-s 1 252 800 tons <br />' ac-ft ~ ~ <br />For reserve base estimates, coal bed 2 is considered to average S feet thick <br />and underlie the entire application area at depths ranging from about 130 feet <br />below the surface in Pine Gulch to 380 feet below the surface on the divide <br />between Pine Gulch and Hay Gulch. <br />120~ac x 5 FC x 1 800 t=ns <br />- ' ac-ft 1,080,000 tons <br />The total amount of coal underlying the application area in coal bed 2 is <br />calculated at 1,080,000 tons, including 297,000 tons of "measured" coal and <br />783,000 tons of "indicated" coal reserves. <br />~ > <br />Novesaber 1993 <br />
