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 (Workings): OPEN PIT; ADITS DRIVEN BELOW PITS FROM THE WEST

Comment (Geology): LOCALIZATION OF TACTITE BODIES CONTROLLED BY COMPOSITION AND BEDDING-IT FOLLOWS BEDDING IN LIMESTONE; TACTITE BODIES ARE THICKEST NEXT TO THE GRANODIORITE AND BECOME NARROWER AND PINCH OUT NORTHWARD ALONG STRIKE OF BEDS.

Comment (Deposit): WORKINGS INCLUDE 3 OEPN CUTS UNDER LEASE TO RONREX MINING CO. IN 1956. OPEN PIT MINING STARTED IN 1951, CONTINUED INTERMITTENTLY THROUGH 1956. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV

Comment (Location): SE 1/4 SEC 31. JUST EAST OF THE RICHMOND MINE

Comment (Development): INTERMITTENT OPEN-PIT MINING 1951-1956. THE MOUNTAIN KING CLAIM, OWNED BY TAYLOR, NEILSEN, AND THOMAS (T.N.T.) OF BATTLE MOUNTAIN, AND ADJOINING PROPERT-Y, LEASED FROM THE SOUTHERN PACIFIC RAILROAD CO., WAS MINED BY- OPEN-PIT METHODS FROM 1951 TO 1956. NO ACTIVITY IN 1984.

Comment (Deposit): THE PROPERTY COVERS A PART OF THE NORTHERN CONTACT ZONE OF THE GRANODIORITE STOCK WITH LIMY SEDIMENTS OF THE PREBL-E FM. PODS OF SCHEELITE-BEARING TACTITE OCCUR IN THE THIN LIM-ESTONE LENSES THAT ARE INTERBEDDED WITH ARGILLACEOUS HORNFELS -WHERE THE STRIKE OF THE BEDDING IS INTO OR AT A SLIGHT ANGLE T-O THE GRANODIORITE CONTACT. THE TACTITE IS THICKEST AT THE CON-TACT AND PINCHES OUT TO THE NORTHEAST ALONG THE STRIKE OF THE -BEDS. THE TUNGSTEN CONTENT OF THE ORE MINED RANGED FROM 0.35 %- TO 0.85 % W03 AND PROBABLY AVERAGED ABOUT 0.6 %. THE DEPOSIT -CONTAINS A SMALL POD OF GARNET-QUARTZ-TREMOLITE SKARN ON THE N-ORTHERN CONTACT OF THE NORTHERN LOBE OF OSGOOD GRANODIORITE. L-IMESTONE SECTION HERE IS DISCONTINUOUS AND TACTITE PODS ARE SM-ALL. THE ZONE COULD CONNECT WITH THAT OF THE RICHMOND MINE TO -THE WEST.
