MINE INFORMATION

The La Sal, Snowball, and Beaver Shaft Mines are under the same Utah Division of Oil, Gas and Mining (DOGM) permit (M037026). The mines three shafts are connected underground. They are also connected underground to the Pandora Mine (M037012), also owned by Denison Mines (USA) Corporation (Denison). These mines form a complex of historic underground uranium and vanadium mines in the vicinity of the rural community of La Sal, on the south flank of the La Sal Mountains in San Juan County. The La Sal, Snowball Mines received a permit from DOGM on December 21, 1978. The permit was never extended, despite the mines being closed down for over ten years.

The Beaver Shaft is less than one half (.5) mile from the center of the town of La Sal: the store, elementary school, and post office. One of the mine's vents is about one quarter (.25) of a mile from the center of town.
