The NBMG Sample Site 2302 is a copper and silver mine located in Humboldt county, Nevada at an elevation of 5,259 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.

Comments

Comment (Location): UNNAMED PROSPECT NEAR ADELAIDE MINE . INFO FROM LAND.ST :(1972)

Comment (Workings): 2 SHORT ADITS

Comment (Development): NO ACTIVITY AT TIME OF EXAMINATION IN 1984.

Comment (Deposit): REPLACEMENT BODIES CONSISTING OF GARNET, IDOCRASE?, PYRRMOTITE, CHALCOPYRITE AND PYRITE OCCUR IN THE VICINITY OF A NEARLY HORIZONTAL THRUST. ROCKS WITH ORIGINAL CARBONATE MINERALS ARE VARIABLY SILICATED. A FEW SPECKS OF SCHEELITE WERE OBSERVED WITH A BLACK LIGHT IN SAMPLE 2302.
