The Black Star Claim Group is a gold mine located in Pershing county, Nevada at an elevation of 4,800 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.
Elevation: 4,800 Feet (1,463 Meters)
Lat, Long: 40.77861, -119.00278

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.

Primary: Black Star Claim Group
Secondary: NBMG Sample Sites 2928
District: Trego Mining Area
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.

Comment (Location): UTM IS FOR SAMPLE SITE 2929, ADIT; UTM FOR SAMPLE SITE 2928 IS N4515870, E331020; UTM FOR SAMPLE SITE 2930 IS N4515670, E330590. . INFO FROM LAND.ST :(1972)
Comment (Development): LOTS OF RECENT LOCAL PROSPECTING ACTIVITY, STAKING, BUT NO ACTIVITY AT TIME OF EXAMINATION IN 1985. MANY GENERATIONS OF CLAIM POSTS. ROAD IS VERY OLD AND BUILT BY HAND.
Comment (Deposit): METAVOLCANICS ON EAST AND GRANODIORITE ON WEST. EXTENSIVE QUARTZ VEIN SYSTEM WITH MOST WORKINGS IN THE GRANODIORITE, ON N-TRENDING VEINS. SMALL ADIT FOLLOWS A N10W VEIN DIPPING 10 W; THIS VEIN WAS OPEN-STOPED ALONG E SIDE OF HILL FOR 200 FT (SAMPLE 2928). ADIT AND INCLINE NEAR MILLSITE EXPLORED SEVERAL VEINS (N10W) IN GRANODIORITE (SAMPLE 2929). LOCALLY, THERE ARE PODS OF BLACK TOURMALINE ADJACENT TO OR NEAR CONTACT ZONES. VEIN MATERIAL HAS BEEN SORTED AND STACKED IN PILES. ONLY VISIBLE MINERALIZATION IN VEINS IS PYRITE AND FE OXIDES.
Comment (Workings): ADITS, OPEN STOPES, MINOR TRENCHING, PROSPECTS, LOADING FACILITY, REMNANTS OF A CRUSHING AND SORTING MILL.
