The Unidentified Occurrence is a iron mine located in Lincoln 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.

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 (Deposit): ABWilson determined that there is insufficient information to maintain separate records for each of the former old records and merged them because they all use the same reference. If someone later determines that these are discrete deposits the record can show the multiple locations in the locations table. NOTE: The Fruchey thesis was not available at the time of record consolidation.
Comment (General): 5 to 6 ft. thick pisolitic hematite bed in the lower part of the Pennsylvanian Wells Formation.
Comment (Location): Location from MS-14. Classified as residual (lag) deposit.
Comment (Geology): DISCONTINUOUS AND SPOTTY HEMATITE BEDS OCCUR THROUGHOUT WESTERN WY WITHIN THE BASAL SECTION OF THE WELLS FORMATION
Comment (Workings): SURFACE PROSPECT
Comment (Location): Location of 10157810 (0560230150) was given as T29N, R 116W, Sec. 19, but reference is for T29N, R117W, Sec. 12.
