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 (Geology): THE ORE CONSISTS OF CHALCOPYRITE, PYRRHOTITE, AND A LITTLE SPHALERITE AND GALENA IN A GANGUE OF CALCITE, GARNET, AND VESUVIANTE. THESE REPLACEMENT-TYPE BODIES OCCUR IN A LIMESTONE INTERBEDDED WITH A DARK CALCAREOUS PHYLLITE. TRACES OF SCHEELITE HAVE BEEN NOTED IN THE MINE WASTE DUMPS.

Comment (Deposit): THIS RECORD HAS BEEN MERGED WITH M231276, WHICH HAS BEEN DELETED.

Comment (Deposit): Discovery Year: 1860S

Comment (Location): SITE CONSISTS OF SIX PATENTED CLAIMS. LOCATED ON EAST FLANK OF SONOMA RANGE. THE ORIGINAL ADELAIDE MINE IS SOUTH OF GOLDRUN CREEK. THE MINE LABELED 'ADELAIDE' ON GOLDRUN (1981-PHOTO REVISED) TOPOGRAPHIC MAP IS ACTUALLY THE ROADSIDE OREBODY, AN EXTENSION OF THE ADELAIDE.

Comment (Production): GROSS YIELD: $11949

Comment (Development): OPERATED FROM 1860S TO 1940 AND YIELDED THE MAJOR PON OF THE GOLD, SILVER, COPPER AND LEAD PRODUCED IN THE DISTRICT. GOLD, SILVER, AND COPPER PRODUCTION BEGAN AGAIN IN 1980, WITH BULLION MONARCH CO. OWNING A 50% INTEREST IN M.ANDB. MINING CO. IN OCTOBER 1980, ABOUT 1000 TONS OF ORE HAD BEEMINED, STOCKPILED AND READIED FOR DELIVERY TO MONARCH'S 200 TPD FLOTATION MILL AT AUSTIN. INACTIVE IN 1984 (GARSIDE).

Comment (Deposit): SULFIDE REPLACEMENT OF MARBLE AND CALCAREOUS SILTSTONE. THE IRREGULAR REPLACEMENT OBSERVED IN THE TRENCH ABOVE THE ADIT APPEARS TO FOLLOW 'TRANSPOSED BEDDING,' (ROCKS ARE ISOCLINALLY FOLDED), ALTHOUGH THERE ARE NORTH-TRENDING HIGH-ANGLE (75W) FAULTS THAT MAY INFLUENCE LOCALIZATION OF SULFIDES AND LOW-ANGLE THRUST FAULTS ALSO APPEAR TO BE PRESENT. ROCKS TO THE EAST OF THE REPLACED UNITS ARE HARD, LAMINATED SANDSTONE AND SILTSTONE. THE CARBONATE-BEARING ROCKS ARE CONVERTED TO CALCSILICATE ROCKS CONTAINING A LIGHT BROWN GARNET. VESUVIANITE IS REPORTED, AS IS SCHEELITE IN THE MINE WASTE DUMPS, ALTHOUGH NO SCHEELITE WAS OBSERVED UNDER BLACK LIGHT IN THE COLLECTED SAMPLE 2301.

Comment (Workings): MAIN SHAFT 300 FEET DEEP ON SOUTH SIDE OF CREEK, AND ADIT 2000 FEET LONG ON THE NORTH SIDE OF THE CREEK AND ABOUT 1 MILE OF UNDERGROUND WORKINGS.
