Re: White Mesa Mill Annual Seeps and Springs Sampling -
Notice Pursuant to Utah Groundwater Discharge Permit UGW370004.
Dear Mr. Lundberg:
Denison Mines (USA) Corp. is providmg this letter to notify the Utah Department of Environmental Quality of
the White Mesa Mill's (the "Mill's") annual seeps and springs sampling event as required by Utah Groundwater
Discharge Permit (the "GWDP") UGW370004. The Mill plans to begin the sampling event on Wednesday,
June 20, 2012.
The Mill staff will attempt to sample the following locations: Coral Canyon Seep, Corral Seep, Ruin Springs,
Cottonwood Seep, Westwater Seep, and Entrance Seep, consistent with the GWDP and the March 2009
Sampling Plan for Seeps and Springs (the "Sampling Plan"). As described in the Sampling Plan, several of
these locations have historically been too dry for sampling. Per the Sampling Plan, beginning Wednesday, June
20, 2012 the Mill staff will make three attempts at sampling each location and will document dunng each
attempt whether or not conditions permit development and samplmg.
If you have any questions or require further assistance, please contact Tanner Holliday or Garrin Palmer at

Yours very tmly,
