The Whirlwind Mine water <br />treatment plant is located at 30100 5/10 Road, Gateway, Colorado 81522. Discharge of <br />treated water from the Whirlwind Mine is allowed in accordance with Colorado <br />Discharge Permit System (CDPS) permit number CO-0047562. <br />On November 24, 2008 the Whirlwind Mine was put on stand-by status. At this time, the <br />mine will continue to be dewatered during stand-by and Energy Fuels will continue to <br />treat and discharge mine water and to comply with CDPS permit conditions. Mine water <br />collects in the mine at a slow rate (approximately 2 to 3 gpm) and is being pumped into <br />the untreated water tank and treated in batch runs, as necessary. Currently, batch runs are <br />occurring at a rate of approximately one run per month. One batch run occurred from <br />October 26 to 30, 2009. A monthly discharge sample was collected on October 28, 2009 <br />in accordance with the aforementioned permit. Analytical sample results indicate that <br />there were no exceedances of the effluent limitations during the October 2009 batch run <br />discharge. <br />Dissolved iron, sulfate, and nitrate levels are being monitored in the discharge samples at <br />the request of WQCD and the Division of Reclamation, Mining and Safety. Dissolved <br />iron in the discharge sample was detected at 0.10 mg/L, sulfate was detected at 132 mg/L, <br />and nitrate was detected at 0.6 mg/L. <br />Energy Fuels, Inc. 44 Union Blvd., Suite 600 <br />www.energyfuels.com Lakewood, Colorado 80228 <br />Phone: 303-974-2140 <br />Fax: 303-974-2141
