• Permit Revision. A copy of this Revised Mine Permit boundary are <br />included with this package as Exhibit 4. <br />Considering the high sulfur history of the Red Arrow Seam at <br />Southfield (see Table 1) production from the 2 North submain has been <br />a pleasant windfall in extending the remaining low sulfur reserves of <br />the Jack O'Lantern Seam. Continued coal prai~iction fran the area <br />outlined in this Technical Revision will allow the Southfield Mine to <br />maintain a high Red Arrow to Jack O'Lantern blending ratio, and <br />continued supply of ca~q~liance coal to their customers. <br />The above referenced mine development, referred to herein as the 2 <br />North submain has defined reserves and is conducting panel development <br />to the limits of sulfur and permit constraints. Prior to the approval <br />of a revised penait bo~adary, additional reserves are required to <br />maintain coal blending productivity. All mining will be done by <br />r+ooc~and-pillar methods utilising continuous mining machines. <br />TABLE 1: RID ARROW QUALITY (WASHID ) <br />ARITHMETIC AVERAiGFS <br />Mine Area No. of Sales" lbs Soy/icrtiBTU <br />• Mains 13 1.72 <br />1 North 8 1.63 <br />1 South 17 1.77 <br />2 North 14 1.52 <br />" Includes charnel samples and cores (having +90~ recovery) <br />within the planned mining area. <br />PROPOSID BOUNCI4RY CHANGE IiDCATION <br />The proposed boundary change area of 46.8 acres situates in the SE 1/4 <br />of Section 24, in T. 20 S., R. 70 W, of the 6th P.M.
