Dear Mr. Anderson:
Energy Fuels Resources (USA) Inc. is providing this letter to notify the Division of Waste Management and
Radiation Control of the White Mesa Mill's tailings, slimes drain, and leak detection system ("LDS") sampling
as required by the Utah Groundwater Discharge Permit (the "GWDP") UGW370004. The sampling event is
scheduled for Tuesday August 4, 2015 and, if necessary, Wednesday August 5, 2015.
The Mill staff plan to sample the following locations, consistent with the GWDP and the Tailings, Slimes Drain
Sampling Program (the "Sampling Program").
Sampling Area Locations
Tailings System Cells Cell 1, Cell 3, Cell 4A, and Cell 4B

As indicated in the Sampling Program, slimes drain samples are only collected from cells which have been
removed from service and are undergoing dewatering procedures. For this sampling event, slimes drain
samples will only be collected from Cell #2. Also as indicated in the Sampling Program, LDS samples are only
collected at locations with sufficient free liquid to permit sampling.
