The Arizona Department of Environmental Quality (ADEQ) has received applications for underground uranium mines from Denison Mines (USA) Corp. Denison has submitted these applications in order to obtain Air and Water Quality Control Permits for the operation of four mines - Arizona I Mine, Pinenut Mine, Canyon Mine and EZ Mine. The extracted uranium ore is not processed on-site; instead it is removed via haul trucks and transported for processing at a mill in Blanding, Utah. For the location of these mines, please view the Denison Mines Map.
