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): Discovery Year: WWI

Comment (Geology): ORE IN SOUTH EDGE OF SMALL ROOF PENDANT IN GRANODIORITE, AS LENSES COMPOSED OF GARNET AND EPIDOTE ASSOCIATED WITH QUARTZ AND LIMONITE. SCHEELITE OCCURS AS DISSEMINATED CRYSTALS UP TO 2 1/2 INCHES, WITH MALACHITE STAINING. TWO BODIES OF TACTITE IN THE STEEPLY DIPPING CAL-SILICATE HORNFELS, ONE 250 FEET LONG WITH MAX WIDTH OF 30 FEET AT THE CENTER DIVIDING INTO LAYERS THAT LENS OUT. SCHEELITE IS UNEVENLY DISTRIBUTED SOME BANDS 1-2 FEET WIDE WITH MORE THAN 1% WO3, AVERAGE CONTENT IS 4% WO4. THE SECOND TACTITE BODY, 220 FEET LONG, AVERAGE 20 FEET WIDE, WITH LOW WO3 CONTENT.

Comment (Location): SOUTH END OF THE SHAWAVE MTNS.

Comment (Production): REPORTED PRODUCTION, 1944, SEVERAL THOUSAND TONS.

Comment (Development): ORIGINALLY DEVELOPED FOR COPPER, BUT PROVED TO BE OF LOW ECONOMIC VALUE. MINED INTERMITTENTLY UNTIL 1961. RECENTLY STAKED BY PBC MINING CO. (1984) . TUNGSTEN MINERALIZATION WAS DISCOVERED ABOUT 1917 AND THE PROPERTY WAS CONTROLLED BY GOLD, SILVER,AND TUNGSTEN, -INC, THE OWNER OF THE NIGHTINGALE MINE. IN 1944 IT WAS ACQUIRE-D BY RARE METALS CORP.AND DURING 1944-1955, SEVERAL THOUSAND T-ONS OF ORE WERE MINED AND CONCENTRATED AT THE TOULON MILL, MOS-T OF WHICH WAS MINED FROM AN OPEN PIT

Comment (Deposit): SHAFTS ON TOP OF HILL ALONG PARALLEL NW-STRIKING VEINS ASSOCIATED WITH FISSURE-FILLING VEIN SYSTEMS POSSIBLY ALONG- JOINT SETS. COPPER MINERALS AND URANIUM OCCUR ALONG STRIKE OF- VEINS. ZONE OF STRONGEST CU-U MINERALIZATION WAS REPORTED TO -BE 300-400 FT WEST OF MAIN OPEN PIT, WHERE A REMNANT OF AULD L-ANG SYNE SEDIMENTS IS PRESERVED AS A ROOF PENDANT. THE ZONES O-F STRONGEST MINERALIZATION ARE THOSE WHICH ARE THE MOST CALCAR-EOUS. THREE SAMPLES FROM THE NURE PROGRAM ASSAYED BETWEEN 144 -AND 334 PPM U; THESE SAMPLES CAME FROM CALCAREOUS SEDIMENTS. S-AMPLE 2864 IS FROM THE CONTACT-TYPE DEPOSIT OF TACTITE . URANIUM IS SPOTTY WITH HIGH-GRADE INDIVIDUAL PIECES, BUT MINING WOULD LOWER ORE GRADE BELOW ECONOMIC LEVELS

Comment (Workings): DEVELOPED BY 2 OPEN CUTS, 3 TRENCHES, 10 FOOT SHAFT AND AN OPEN PIT.. IN 1984,ONE 30-FT SHAFT, 350-FT TUNNEL, SEVERAL LARGE OPEN PITS, AND MANY TRENCHES AND PROSPECTS . 100 5-FT DEEP DOZER CUTS FOR URANIUM

Nevada Gold

Nevada has a total of 368 distinct gold districts. Of the of those, just 36 are major producers with production and/or reserves of over 1,000,000 ounces, 49 have production and/or reserves of over 100,000 ounces, with the rest having less than 100,000 ounces. Read more: Gold Districts of Nevada.
