• boundary was as projected but the north boundary was not intercepted. <br />in recent months additional drill hole records have been made <br />available to EFCI for the area north of the current lease boundary. <br />Information from these records and fran the abandoned Radiant Mine <br />Ca:iplex to the north indicated the possible existence of a narrow <br />"corridor" of 4 1/2 to 6 foot coal extending from 2 North into the <br />Radiant Mine Complex. This area to the northeast of 2 North will be <br />included i.ri the upoaning Permit Revision. <br />Extensive channel sampling and prep plant analyses show the Red Arrow <br />reserves opened by the 2 North advance to be relatively low in sulfur <br />content (1.3 - 1.4 lbs SOz/mmBTUI. Although these reserves are not a <br />conQliance product as defined by the 1.2 lbs SOy/moB'1V, they allow <br />more Red Arrow tonnage to be blended with Jack O'Iantern reserves <br />thereby extending compliance mine life. <br />Development of production panels to the west of 2 North submain <br />will allow continued Red Arrow production conducive to blending with <br />the Jack O'Iantern during the time period between the approved Mine <br />Permit Renewal and the approved Revised Mine Permit Application. <br />lIINE DEVE[OPMENT <br />Since the acquisition of the mine property in 1985 the croal production <br />fr+an the Southfield Mine has been subject to the SOZ restrictions of <br />• 1.2 lbs SOZ/mmBTU. Before the 1987 drilling, the sulfur content of <br />the Red Arrow Seam averaged 0.9~ sulfur resulting in a 1.1 - 1.6 lb <br />SOz/mmBTU calculation. To maintain a maximum of 1.2 lbs soz/mmBTU, <br />the blending ratio of Red Arrow to Jack O'Iantern was 1:3. After <br />1987, development into the 2 North area allowed a 1:2 blending ratio <br />of Red Arrow to Jack O'Iantern coal. <br />In 1989, anew contract with the Ideal Cement Plant near Florence, OD <br />was initiated to receive coal having sulfur characteristics similar <br />to the Red Arrow Seam. This contract plus the laer than average <br />sulfur values being produced fran 2 North allowed the Red Arrow to <br />Jack O'Iantern blerdi.rg ratio to exceed 2:3 and even approach 1:1. <br />Beginning in 1990 a second continuous miner will be available for <br />additional Red Arrow production. This machine is scheduled to proceed <br />to permitted reserves in either 2 North or 1 South. As the approval <br />of the Revised Permit may well take until after mid-1990, the second <br />Red Arrow ~`-+;*+P will proceed to the higher sulfur reserves of 1 <br />South where 9oz .values often exceed 2.0.
