Energy Fuels Interim Drilling Results Expands Whirlwind Uranium Deposit

TORONTO, ONTARIO--(Marketwire - Sept. 11, 2007) - Energy Fuels Inc. (TSX:EFR) "Energy Fuels" or "the Company" is pleased to release interim results from Colorado drilling on the Whirlwind Mine property, located in both Colorado and Utah, as recommended by the NI 43-101 report for the property filed January 3, 2007. The fourteen holes that have been completed in Colorado are part of the ongoing drilling program to provide stratigraphic data for detailed mine planning, and additional exploration to expand the resource to support the development and near term production strategy of the Company. These drill holes encountered additional high grade mineralization over significant widths. Drilling highlights include:

Selected Data
Thickness Radiometric
Hole ID Ft. Grade- %U3O8
WW07-1 1.5 0.84
WW07-4 2.0 0.43
WW07-5 1.5 0.57
WW07-10 1.5 0.53

"These results confirm that the Whirlwind Mine property is a rapidly expanding near production deposit. The stratigraphic data collected from the drilling also provides critical information for the detailed mine planning being conducted internally," commented George Glasier, President & CEO. "These drill holes overlay the alignment of the planned development drift which will connect the Whirlwind works with the Packrat Mine works. We are also very pleased that three of these drill holes, closely offsetting existing historical holes, have provided strong verification of the historic Whirlwind drill hole data held by the Company. These drilling results confirm Energy Fuels' projected trends within the river channel deposition model upon which it has based its development plans at Whirlwind."

Uranium mineralization was identified in all but one of the 14 holes completed. Seven of the holes show radiometric U3O8 grades ranging from 0.10% to 0.84%. Mineralized thicknesses encountered were up to 7.5 ft. Lower grades were encountered in six holes as detailed in the table below:
