Poison Basin Uranium District

The Poison Basin Uranium District is a uranium mine located in Carbon county, Wyoming.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Location): Juniper Ridge drill holes (the ones labeled on exploration map from Crosshair Exploration Corp, http://www.crosshairexploration.com/s/JuniperRidge.asp) are centered around 41.037, -107.760 (NAD27).

Comment (Deposit): Dahlkamp says the Poison Basin deposit resources "amount to almost 100 t U".

Comment (Deposit): Dahlkamp (p. 207) says, "The Teton No. 3 deposit, located about 3 km to the W of the Poison Basin deposit, comprises narrow, discontinuous flat-lying ore lenses, less than 1.5 m thick, in an area 210 m long, 60 m wide, and 25-30 m deep. Average ore grade is 0.17% U with some pods exceeding 1% U."

Comment (Deposit): About the Juniper Ridge deposit, Dahlkamp (2010, p. 207) says, "Resources recoverable by open-pit mining amount to some 3,000 t U at an average grade of 0.05% U (cutoff grade of 0.17% U). They are contained in three minable ore bodies at depth of less than 80 m. About one third of these resources is above the water table and consistes of oxidized ore, mainly autunite with minor brannerite."

Comment (Production): Gregory and others, 2010, MS-94 lists the following production totaling 124,867 tons of ore (no grade is given, therefore the amount of contained uranium can not be computed): Teton Group (1000 tons, est.), Cedar Hills (20,867 tons), Teton Group (1000 tons, est, but note that this is the same name and same tonnage. Could it be a duplicate record with alternate location?), Poison Basin and Matt 3 (61,000 tons), Jack Rabbit (47,000 tons).
