Tallahassee Creek
Surface radioactive anomalies led to uranium discoveries in 1954 at Tallahassee Creek in Fremont County. Mining in the 1950s was by both underground and open-pit methods.
Exploration in the 1970s by Cyprus Mines and Wyoming Minerals defined two orebodies: the Hansen orebody, estimated to contain 12 million pounds of U3O8, and the Picnic Tree orebody, estimated to contain 1 million pounds U3O8. Uranium is present as uraninite, coffinite, and meta-autunite in Eocene and Oligocene arkosic sandstone, congolmerate, and in sediments interbedded with Miocene volcanic flows. uranium is associated with carbonaceous material, and pyrite. The source of uranium is thought to be the Oligocene Wall Mountain Tuff.
In December 2006, the Australian company Black Range Minerals bought rights to mine the Taylor Ranch property, which the company describes as a 30-million pound uranium orebody that had been discovered in the late 1970s, but abandoned because of low uranium prices. The company plans an extensive drilling program in 2008 to delineate the orebody.

Famous quotes containing the word creek:
“The only law was that enforced by the Creek Lighthorsemen and the U.S. deputy marshals who paid rare and brief visits; or the “two volumes of common law” that every man carried strapped to his thighs.”
