Gibellini Manganese Mine

The Gibellini Manganese Mine is a manganese mine located in Eureka county, Nevada at an elevation of 7,001 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.

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.

Land Status

Land ownership: BLM Administrative Area
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 (Commodity): SECONDARY ZN AND NI MINERALS ARE PROBABLY PRESENT

Comment (Development): 13 UNPATENTED LODE CALIMS. SEVERAL SHIPMENTS MADE FOR TESTS BUT NO PRODUCTION WAS RECORDED. THE USBM EXPLORED PROPERTY AND DRILLED 6 HOLES IN 1946.

Comment (Deposit): UNPUBLISHED MODEL NAME: PGE-ENRICHED BLACK SHALE.

Comment (Geology): THE METALS ARE PRESENT AS IMPURITIES IN THE MANGANESE OXIDES. THE OREBODY IS ON THE FOOTWALL OF A NORTHEAST STRIKING FAULT WHICH DIPS 45 NW. THE KEROGENOUS MUDSTONES OF THE WOODRUFF FORMATION, WHICH CONTAIN UP TO 30 PPB PT AS WELL AS OTHER METALS, MAY BE A POTENTIAL SOURCE ROCK FOR THE GIBELLINI MINERALIZATION

Comment (Location): LOCATION GIVEN IS FOR PPROSPECT SYMBOLS ON BORDER BETWEEN SECTIONS 35 AND 2

Comment (Workings): SHAFT, ADIT, PITS, TRENCHES

Comment (Deposit): RECORD W000698 HAS BEEN DELETED.
