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): Should be depicted with a polygon, not a point.

Comment (Orebody): Strathmore Minerals Corp. owns the Ketchum Buttes Property (no detailed information about the exact location or extent of their property as of 2006). They report a near surface uranium deposite with a planned conventional open-pit uranium mine in sandstone and conglomerate of the Miocene Browns Park Formation. Purchased from Pathfinder Mines Corp (part of AREVA (Cogma)). Historic non-43-101 compliant demonstrated resource of 1,135,000 tons @ 0.064% U3O8 containing 1,454,900 lbs (not tons) of U3O8.

Comment (Identification): District includes the Ketchum Buttes claims, Del Oro claims, and others. As of field visit in 2009 by Anna Wilson and Bill Heran (USGS) there is very little evidence that anything was mined here.

Comment (Production): According to the values reported on MS-94 (Gregory and others, 2010), the 2 productive mines in the district produced a total of 2061 tons of ore (not uranium). There is no mention of the ore grade, therefore total contained uranium can not be estimated. Ketchum Buttes produced 143 tons, Del Oro produced 2,048 tons.
