Wyoming uranium mine spill one of the largest recorded in U.S.
The Lost Creek uranium mine north of Rawlins shut down operations Wednesday just weeks after reporting one of the largest spills of uranium injection fluid ever recorded in the U.S.
The spill was contained on site and is not a human health hazard, according to federal regulators. The spilled fluid had not yet been pumped into the uranium ore beneath the surface. Radioactive metal contained in the fluid was naturally occurring.
The mine, owned by Littleton, Colorado-based Ur-Energy, reported an Aug. 19 spill of 188,000 gallons of pre-injection fluid at Lost Creek. Another spill of 10,000 gallons of pre-injection fluid at Lost Creek on Tuesday was reported to federal regulators.
