As stated in the attached narrative, the sealing procedure outlined is the same <br />procedures and equipment that were used with great success for sealing and reclaiming the drill <br />holes and water monitoring wells at Energy Fuels' Kerr /Marr mine located in Jackson County, <br />Colorado. The Colorado Bureau of Land Management (BLM) and the Colorado Division of <br />Reclamation Mining and Safety (DRMS) accepted and approved these procedures at the <br />Kerr /Marr (Kerr) mine. <br />Glenn Miller, geohydrologist at Pronghorn Geologic Services of Gillette, Wyoming <br />oversaw the hole /well reclamation at Kerr and Mr. Miller installed many of the holes at <br />Southfield and recorded the geohydrology. DLD Pipe Recovery Services of Grand Junction, <br />Colorado, utilizing their equipment, did the hole /well reclamation field work at Kerr. EFCI is <br />contracting with both of the above contractors to do the hole /well reclamation work at Southfield. <br />The experienced contactors will be beneficial to the Southfield sealing operation. <br />A list of open holes /wells surveyed during the recent (June -July, 2014) field <br />reconnaissance at Southfield is enclosed with this submittal as well as the respective updated <br />map, replacement pages, descriptive narrative and revision form. <br />If you have any questions or need additional information please contact me. <br />Sincerely, <br />orge V P tterson <br />Energy Fuels Coal, Inc. <br />Enclosures: Application Revision Form; <br />List of open drillholes /wells surveyed at Southfield; <br />Descriptive narrative of hole /well sealing procedure; <br />Replacement pages 4.07 -1 and 4.07 -2 to be replaced in Section 4.07.3, <br />"Permanent Sealing "; <br />Updated map, Mine Area Surface and Groundwater Hydrology, Map 12. <br />
