Bowie Resources, LLC Bowie No. 2 Mine 2011 Annual Hydrology Report March 26, 2012 destroyed by longwall mining during 2001. DH -58 and 58a were eliminated by mining during late 2003 so they will no longer be monitored. Drill holes DH -65, DH -66, DH -67D, DH -67b1w and DH -67abv were added in conjunction with the Ironpoint Federal coal lease, with some monitoring beginning during the fall of 2000. DH -67D was damaged during 2003 so no monitoring was performed. The DH -67 holes were refurbished during 2004. DH -66 was eliminated by mining during early 2004 so it is no longer monitored. Drill holes DD- NM4X98 -27, 28 and 29 were in -mine monitoring holes which were added to the monitoring program during 2003. The three monitoring points were abandoned when the mine activity retreated from the east mains in mid 2004. TC- 01 -01, 02 and 03 were added to the monitoring program during 2003. Drill holes CWI -DH -58 and CWI -DH -60 were added to the monitoring program in 2011 with the approval of permit revision 12 to cover the area west of Terror Creek. The Applicant drilled DH 2010 -1 during 2011. Two monitoring wells were established at DH 2010 -1. One well is completed in the B -Seam and the other is completed in a water bearing zone above the B -Seam. Conclusion The results of the hydrologic monitoring conducted during the 2011 season indicate consistent chemical and physical properties when compared with the baseline values provided in the permit application. Longwall mining is the focus of all mining operations at Bowie No. 2 Mine. This mining method has not affected the local hydrology during the current year. Water quality at all monitored sites remains good overall and no chemical or physical impacts have been noted. Except as noted above, none of the field or laboratory parameter results indicate an adverse impact associated with the mining operations of the Bowie No. 2 Mine on the local hydrology. 6
