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 (Reserve-Resource): Dahlkamp (p. 176) says, "Uranium deposits occur in the central part of the basin. They contained original resources of more than 47,000 t U at grades ranging from <0.07 to 0.5% U."
Comment (Deposit): Dahlkamp, 2010, p. 179: "Ore bodies group in an area some 15 km in length and up to 5 km in width in the central part of the Sirley Basin. Major ore bodies lie at depths between 50 and 100 m at the edges of the earlier mentioned two oxidzed sandstone tongues."
Comment (Identification): Kerr-McGee Corp. Pit shown on Fig. 25 of PP-745 is not mentioned by this name in any of the other literature. Uncertain what this mine is.
Comment (Identification): Includes many properties including those owned by Cameco, Petrotomics, and Uranium Energy Corp.
Comment (Production): According to the values reported on MS-94 (Gregory and others, 2010), the 7 productive mines in the district produced a total of 18,080,489 tons of ore (not uranium). There is no mention of the ore grade, therefore total contained uranium can not be estimated. Productive mines: Pathfinder-Shirley Basin (7,170,586 tons), Night Owl (93 tons, small relative to the others in the area, but this is just east of the district), Uranium Supply-Jenkins (528,582 tons), North Walker (740,117 tons), South Walker (264,000 tons), Getty Oil-Petrotomics (9,372,211 tons), Nall (4,900 tons).
