0 D2B2 <br />The D2132 borehole was completed in December 2005 in the vicinity of the Hubbard Fan. Water <br />transfer started during early 2006. The bottom 39' of the 338' borehole is uncased. The B seam <br />coal roof was encountered at 6046' elevation. After initial water transfer, initial water level was <br />encountered at 6053' elevation, or 7' above the coal. Subsequent measurements encountered an <br />apparent dry borehole obstruction at the 6070.7' elevation or 24' above the coal. The obstruction <br />has not precluded water transfer, but has limited the ability to lower the sounder past the <br />obstruction. During 2008, the sounder encountered more favorable conditions and a water level <br />appeared at the 6064' elevation. During 2008 the underground pumps ran very little. On October <br />12, 2008 the 13 West gate road was sealed, the Hubbard fan dismantled, the shaft sealed with <br />earthen materials and the western mining district sealed off. Pumping of water to D2B2 was also <br />concluded. <br />Water Level (Elevation Ft.) <br />Date D2B D2B2 <br />• <br />January 14, 2005 6044.0 - <br />January 19, 2005 6044.0 - <br />February 22, 2005 6044.6 - <br />March 31, 2005 6043.6 - <br />May 3, 2005 6044.0 - <br />June 15, 2005 6044.5 - <br />Jul 11, 2005 6043.6 - <br />August 24, 2005 6044.6 - <br />October, 17, 2005 6045.0 - <br />April 19, 2006 - 6053 <br />May 25, 2006 6047 - <br />June 7, 2006 - 6066.7 <br />July 26, 2006 6047 6070.7 <br />October 17, 2006 6045 - <br />December 27, 2006 6047 6070.7 <br />May 23, 2007 6047 Indeterminate <br />June 19, 2007 6049 Indeterminate <br />August 16, 2007 6049 Indeterminate <br />June 18, 2008 6052.5 6063 <br />September 11, 2008 6064 <br />October 15, 2008 6051 <br />The data suggests that minor changes to B seam water level have occurred likely not only from <br />mine water transfers but natural sources as well.

Once a year, samples of water are taken of water transferred to D213 and D2132 and summarized <br />below. The access to the pumps leading to D2B2 were sealed before samples were taken. There <br />were no unique conditions in the mine that would suggest the samples, had they been available, <br />14
