The Miller Hill area is a uranium mine located in Carbon county, Wyoming at an elevation of 7,861 feet.
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.

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.

Land ownership: Private
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments
Comment (Production): Produced an unknown amount of uranium ore (MS-94). An Unknown mine in this area produced 8 short tons of ore (MS-94).
Comment (Reserve-Resource): "As much as 0.5% uranium is ocntained in grab samples, but only about 1,000 tons of rock is known to contain as much as 0.03% uranium." (Vine and Prichard, p. 201). "Several hundred tons of rock averaging about 0.02 to 0.03% uranium are believed present in the area" (Bull. 50, p. 210).
Comment (Identification): Someone entered separate records for each section in which there are sniffs of uranium. All these are part of the same deposit.
Comment (Location): Miller Hill area includes (MINOBRAS, p. 54) T16N, R87W, sec. 11 T17N, R86W, sec. 29 T17N, R87W, sec. 33 T17N, R88W, Secs. 25, 35, 36 T17N, R89W, NE4
Comment (General): MINOBRAS, 1976, p. 54: "Uranophane was discovered during 1954 in the Miller Hill area located about 25 miles south of Rawlings in west-central Carbon County. Uranium is disseminated within limestone, and fracture coatings, vug fillings in a brecciated silicified limestone, North Park (?) Formation. These occurrences are of the secondary-type, and believed to have been leached from tuffaceeous sandstone. Small high-grade pods contain a maximum of 0.5% U3O8, but their size limits their value. There are reported outcrops in the range of 0.03 to 0.05% U3O8."
Comment (General): Circular 278 describes several "deposits". These are geochemical anomalies and are all part of the Miller Hill area. Any individual records for these sample sites have been removed. ( ie. VW-1253- MRDS DC06939 = 10018827).
Comment (Ownership): One of the deleted records (MAS 0560070260, suggested that the operator was "CITY OF RAWLINS,ISSUED FROM STATE(?)" No further information provided and only citation was to an AEC airborne anomaly. CITY OF RAWLINS listed as a reference for 0560070290 = 10254888.
Comment (Deposit): URANOPHANE IN VUG FILLINGS OF FRACTURED BRECCIATED LIMESTONE, NORTH PARK FORMATION (MIOCENE). SED U.
