NBMG Sample Site 2313

The NBMG Sample Site 2313 is a gold and silver mine located in Humboldt county, Nevada at an elevation of 5,860 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: 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 (Deposit): OCHEROUS GOSSAN AND SPOTTY VEIN QUARTZ OCCUR ALONG ONE OR MORE N 30-40 W, HIGH-ANGLE FAULTS IN LIGHT GRAY CHERT. RARE PYRITE REMNANTS WERE NOTED. THE ZONE OF FAULTS IS LESS THAN 25 M WIDE; MINERALIZED FAULTS ARE DEFINED BY PITS AND ADITS. SOME CRUSTIFORM QUARTZ-GOSSAN (ORIGINALLY SULFIDE) BANDING WAS NOTED IN ONE PIT. MARSH AND ERICKSON SHOW A NW-TRENDING FAULT HERE. A DIKE OF QUARTZ MONZONITE IS SHOWN NEARBY TO THE WEST. SIMILAR OXIDE COPPER AND GOSSAN PROSPECTS ARE EXPOSED IN TRENCHES IN S/2 SEC 29, T 34 N, R 42 E DIRECTLY ADJACENT TO THE INTRUSIVE MASS OF QUARTZ MONZONITE. CONSIDERING THE MINOR NATURE OF THE PROSPECTS, THERE HAS BEEN A CONSIDERABLE AMOUNT OF BULLDOZER TRENCHING IN AN AREA, OF 6-7 KM 2. BULLDOZER ROADS IN E2, SEC 30, T 34 N, R 42 E, ARE NOT SHOWN ON THE REVISED (1981) TOPO SHEET, AND ARE CERTAINLY LESS THAN 5 YEARS OLD. THE ROADS ARE FOR DRILL PADS FOR ROTARY DRILL HOLES, PRESUMABLY FOR PRECIOUS METALS. THIS ACTIVITY MAY BE RELATED TO CLAIM STAKING OF THE
