Sulfur, dry• 0.87% "Reserve Base" estima[es were calculated in accordance with General Mining Order No. 1. The "Coal Reserve Base Pfap" shows the location of drill holes which were used to calculate tonnages. A work map has been included which shows'Siow the lease was divided into sections so acreages could be obtained. The "Coal Recovery Chart - Reserve Base" shows each block along with coal thicknesses and calculated in-place tons. Ia calculating the "Reserve Base" for this lease all 2522.37 acres • were wed res:.ltinb iu 39,12J,317 cc:..,. Although more information is needed in the northern portion. of the Lease, this is the tonnage calculated using the guidelines given. Figuring "Mineable Reserve", thicknesses ranging from 5.26 to 7.80 feet were used is the calculations. These heights provide us with a seam, the quality of which, would be gOOd enough to economically mine. In some areas, if thickness was increased additional partings would be picked up greatly increasing the ash content of the mine run coal. This results in total "Mineable Reserve" of 31,260,176 tons. Due to certain factors, i.e., OSPS, subsidence, State of Colorado, etc., no detailed mine plan has been drawn up at this time. Recoverable reserves were therefore calculated by first deducting coal contained in • a 50 foot boundary strip (466,717 tons) and then using a recovery factor of 507, for [he remaining acreage. This results in a total of 15,39G,730 tons. ?lo allowance has been r..ade For coal under more than 2000 feet of cover. This will have to be determined as minim progresses.
