The geological information contained in the RM was reviewed by a staff geologist and found to be sufficient for use by the geologists and mining engineers. Appropriate o te geological coaleserves containe maps rdonted thefor leases in determining the extent questions. The following coal o quality ss to be contained ai ned in the R2P2 package on a seam by seam basis for lbseam 0 Moisture wt % . 0 Ash wt S 0 Sulfur wt S 0 Volatile Muter wt S 0 Fixed Carbon wt S 0 Heating Value Btu/lb 0 Summary of Mineral Analysis of Ash Data and Chlorine content including, Si02, A1203, T102, Fe203, CaO, MgO, K20, Na20, S03, P:205, SrO, BaO, Mn304, undetermined, and chlorine. This information is of sufficient quality to determine the quality of the mineable reserve base. The coal seams will be mined using Longwell and convention (Room with Pillar) mining techniques with the standard equipment associated these two mining practices. Mining sequence information is contained on mine plan maps showing development on a year by year basis. The production rate is contained in the text of the R2P2 on a year by year, seam by seam basis. The estimated overall recovery factor acttotafo thbeertwwo seams to be mined (the B 8 D seams) is 42.6 percent. The acres contained by the ' (5) leases (C-023 of 103, D-047201 , C-0126669, C-8424, and C-8425) is 6441 .60. The estimated reserve bases were submitted by the company including in-place, mineable, and !'recoverable reserves. These figures were checked for accuracy by- the staff of this offiCO for all seams. Further analysis was performed for the two seams to be mined since mineable and recoverable reserves are only present in the B and D seams. The results of this analysis are as follows: The total in-place reserves were calcualted by a staff geologist at this office.
