RE: Submittal of July'2009 Discharge Monitoring Report r/
To Whom It May Concern:

Energy Fuels Resources Corporation (Energy Fuels) is providing the attached Discharge
Monitoring Report (DMR) for the month of July 2009. The Whirlwind Mine water
treatment plant is located at 30100 5110 Road, Gateway, Colorado 81522. Discharge of
treated water from the Whirlwind Mine is allowed in accordance with Colorado
Discharge Permit System (CDPS) permit number CO-0047562.
On November 24, 2008 the Whirlwind Mine was put on stand-by status. At this time, the
mine will continue to be dewatered during stand-by and Energy Fuels will continue to
treat and discharge mine water and to comply with CDPS permit conditions. Mine water
collects in the mine at a slow rate (approximately 2 to 3 gpm) and is being pumped into
the untreated water tank and treated in batch runs, as necessary. Currently, batch runs are
occurring at a rate of approximately one run per month. One batch run occurred from
June 27 to July 1, 2009. A monthly discharge sample was collected on June 29, 2009 in
accordance with the aforementioned permit. Although no sample were collected in July,
the June 29 sample was collected during the same batch run and is representative of the
discharge that occurred on July 1. Analytical sample results indicate that there were no
exceedances of the effluent limitations during the July 2009 batch run discharge.
Dissolved iron, sulfate, and nitrate levels are being monitored in the discharge samples at
the request of WQCD and the Division of Reclamation, Mining and Safety. Dissolved
iron in the discharge sample was less than 0.03 mg/L, sulfate was detected at 62 mg/L,
and nitrate was detected at 0.7 mg/L.
