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 (General): TYPE WORKING-SHAFT 365FT AND 5000FT DRIFTS. This same info is in Hausel, 1993, WGS PIC-32, p. 33 under the description for the Keystone Mine. But it is not clear that MINOBRAS is describing the Keystone mine or something in the vicinity.

Comment (Deposit): DEPOSIT TYPE-PRECAMBRIAN METAMOR. "uranium occurrence in paragneiss"

Comment (General): Unclear exactly what this pertains to. MINOBRAS, 1976, p. A-3, simply lists Keystone as the name, location as Sec. 21, 14N-78W, and comment "uranium occurrence in paragneiss".

Comment (Location): MINOBRAS, 1976, p. A-3, lists location as R78W. This would be 6 miles east of Keystone mine. If that is a typo, and they meant R79W, then this could be that someone found hints of uranium at the Keystone mine, or slightly west of the mine (the mine is in sec. 22, the record in MINOBRAS says sec. 21.) At any rate, Keystone mine has never produced uranium. Therefore, these records must remain separate.
