Land Status

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.

Comments

Comment (Deposit): Discovery Year: 1860S (1936 TUNGSTEN)

Comment (Deposit): TUNGSTEN CONTENT RANGES FROM 1.3 TO 5 % WO3, AS MUCH AS 1.5 % CU AND AS MUCH AS 0.14 OZ AU/TON. DEPOSIT IS PARALLEL TO ENCLOSING ARGILLITE THAT THINS AND SWELLS ALONG STRIKE AND DOWN DIP. SCHEELITE OCCURS IN THE TACTITE AND IN QUARTZ VEINS THAT CUT THE OTHER ROCKS. SCHEELITE FORMS SUBHEDRAL TO EUHEDRAL GRAINS AND IS COMMONLY DISSEMINATED THROUGH THE TACTITE, BUT LOCALLY THE GRAINS ARE DISTRIBUTED ALONG CRACKS OR OCCUR IN SMALL QUARTZ VEINLETS. THE SCHEELITE FLUORESCES WHITE AND YELLOW DUE TO VARYING MOLYBDENUM CONTENT. PARTS OF THE TACTITE BED CONTAIN ABNORMAL AMOUNTS OF BERYLLIUM BUT THE DISTRIBUTION IS IRREGULAR.

Comment (Workings): STOPES, DRIFTS

Comment (Deposit): 2 ADITS WITH ABOUT 400 FEET OF DRIFTS, AN INCLINED WINZE, THREE RAISES AND A SUBLEVEL 35 FEET BELOW THE MAIN LEVEL. THE ORE WAS STOPED 200 FEET TO THE SURFACE. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV

Comment (Deposit): THIS RECORD HAS BEEN MERGED WITH M060456, WHICH HAS BEEN DELETED.

Comment (Location): NORTH END OF EAST RANGE, APPROXIMATELY 2 MILES EAST OF ROSE CREEK. UTM IS UPPER ADIT WHERE NBMG SAMPLE TAKEN.

Comment (Development): FIRST LOCATED FOR COPPER AND GOLD BUT NO EXPLORATORY WORK WAS DONE UNTIL TUNGSTEN WAS DISCOVERED. SHEELITE WAS MINED FROM TACTITE BUT NOT FROM QUARTZ VEINS. ALTHOUGH DEVELOPMENT BEGAN IN 1937, MINING OCCURRED BETWEEN 1943-44 AND 1954-55.

Comment (Geology): EXPOSED ROCKS ARE DOLOMITE, LIMESTONE, ARGILLITE AND QUARTZITE, INTRUDED BY GRANODIORITE, LAMPROPHYRE, AND DIABASE. CALCAREOUS ARGILLITE BEDS ARE CHANGED TO SKARN FOR SEVERAL HUNDREDS OF FEET FROM IGNEOUS CONTACT. THE SKARN CONSISTS LARGELY OF DIOPSIDE, ACTINOLITE, EPIDOTE, QUARTZ, FELDSPAR, AND CALCITE, WITH SMALL QUANTITIES OF SCHEELITE, PYRITE, MOLYBDENITE, SPHALERITE, ARSENOPYRITE, AND CHALCOPYRITE.

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.
