Please find attached the 2012 AHR where George P first <br />discusses the obstruction in detail in the text narrative. The report of the obstruction initiated the <br />DMRS investigation which included the first attempt at using the borehole camera. <br />I know of no prior indication or concern about the condition of MWNW expressed by either EFCI or <br />the DRMS until 2012. All evidence and data reported is believed accurate to the mine floor until <br />2012. Had the obstruction occurred at sometime prior to 2012, it is reasonable to assume that GP <br />would have encountered issues at the obstruction. THe exact timing of the casing damage cannot <br />be determined but all information suggestes it occurred in late 2011 or early 2012. 1 count around 18- <br />20 water level measurements (dry) to the mine floor prior to the obstruction being positively <br />identified. Unless the DRMS has information that EFCI is not aware of, we believe the data as <br />reported for MWNW is accurate and an official part of the mine hydrologic record. <br />As I mentioned, EFCI is exploring the possiblility of any additional data that may exist or be <br />available with regard to water, or the lack of water, in the mine workings. If these data are <br />determined to be useful, EFCI will submit it as soon as possible. <br />Kent Gorham <br />Gorham Energy Consultants, LLC <br />13356 Wild Basin Way <br />Broomfield CO 80020 <br />(303) 870-3787 (c) <br />(303) 465-1274 (h) <br />This message contains confidential information and is intended only for the individual(s) named.
