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 (Location): NEAR COMMON SECTIONS CORNER, UTM TAKEN AT SECTION CORNER

Comment (Deposit): CINNABAR OCCURS IN IRREGULAR FRACTURES FILLED WITH OCHEROUS GOSSAN IN GREENSTONE. SHALLOW UNDERGROUND WORKINGS FOLLOW A N35E 55NW FAULT ZONE WHICH FLATTENS TO NEAR HORIZONTAL NEAR THE GROUND SURFACE. GREENSTONE IS ARGILLICALLY ALTERED NEAR THE FAULT. THIS ZONE OF ARGILLIC ALTERATION MAY CONTAIN CINNABAR ALTHOUGH IT WAS NOT OBSERVED. THE CINNABAR SEEN WAS IN 1-4 CM WIDE IRREGULAR, VERTICAL, TO HORIZONTAL FRACTURES AND OPEN SPACES FILLED WITH POWDERY LIMONITE. SOME BOXWORKS AFTER A SULFIDE MINERAL WERE NOTED IN A PROSPECT TRENCH NEAR THE CORNER OF SECS. 16, 17, 20, 21. RARELY, 1-3 MM QUARTZ VEINLETS OCCUR IN THE LIMONITE ZONES. THE SPARSE CINNABAR SEEN OCCURS MORE COMMONLY WITH DARK BROWN LIMONITE OR WITH THE QUARTZ VEINLETS. THE ALTERATION NOTED IN OTHER PITS IN A 1 SQ KM AREA IS ARGILLIC, WITH STRONG LIMONITE STAINING. SILICIFICATION SEEMS TO UNDERLIE THE ARGILLLIC ALTERATION AT THE PIT AT THE CORNER OF SECS. 16, 17, 20, 21. THIS SILICIFICATION IS INTENSE, COMPLETELY

Comment (Deposit): REPLACING THE GREENSTONE, AND RESEMBLING THE OPALITE IN REPLACEMENT OPALITE MERCURY DEPOSITS.

Comment (Workings): OPEN PIT. FROM THE SOUTH CORNER OF THE CUT A 40-FT ADIT FOLLOWS A FAULT BETWEEN GREENSTONE AND TUFF; FOR 1/2 MILE SW OF MAIN PIT ARE ABOUT 6 ROTARY BULLDOZER TRENCHES UP TO 300 FT LONG, 15 FT DEEP, AND AT LEAST 2 ROTARY DRILL HOLES.

Comment (Development): OPEN PIT MINING IN 1968 AND 1969. THE 10 RICKY BOY CLAIMS WERE LOCATEDN 1957 BY THOMPSON AND BEATTY ON THE SITE OF SOME LONG-ABANDONED PROSPECT HOLES. LITTLE WORK WAS DONE ON THE PROPERTY DURING THE YEARS OF DECLINING MERCURY PRICES. BEATTY RELOCATED THE GROUND IN 1964 AND IN THE MID-1960'S CROFOOT MINING CO. DID SOME EXPLORATORY DRILLING UNDER LEASE. IN 1967, H.A. HORTON, UNDER LEASE-OPTION, FOUND SOME GOOD ORE WHILE DOING CONTRACT BULLDOZING TO COMPLY WITH ASSESSMENT REGULATIONS AND SOON NEGOTIATED A LEASE FOR THE LIFETIME OF THE MINE. IN LATE 1967, HE LEASED A ROTARY FURNACE IN WINNEMUCCA AND BEGAN PROCESSING VERY RICH CINNABAR ORE HAULED ABOUT 30 MILES FROM THE MINE. THE RECOVERY PLANT WAS REMODELED TO ACHIEVE LARGER CAPACITY, AND OPERATED UNTIL 1969, DURING WHICH TIME ABOUT 500 FLASKS OF MERCURY WERE RECOVERED. DURING THE SAME PERIOD 1450 TONS OF LOWER GRADE ORE HAULED TO THE NEW ROTARY FURNACE PLANT OF STAR CITY MINES, LTD, IN WINNEMUCCA YIELDING ABOUT 100 FLASKS HG.

Comment (Geology): MINERALIZATION IS IN ALTERED GREENSTONE AS FINE CRYSTALS OF CINNABAR IN LIMONITIC ZONES. THE HOST ROCK CONTAINS NUMEROUS CALCITE AND QUARTZ VEINLETS. THE RICHEST ORE IS ASSOCIATED WITH THE CALCITE VEINLETS. CINNABAR OCCURS AS DISCRETE CRYSTALS AND ANHEDRAL AGGREGATES IN CALCITE AND IN THE HOST ROCK.

Comment (Deposit): THE MINE DISCOVERED IN 1967. MINING BY OPEN PIT IN 1968 AND 1969 PRODUCED 487 FLASKS OF MERCURY ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV

Comment (Development): NO ACTIVITY AT TIME OF EXAMINATION IN 1984.

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.
