Gold Quarry Mine

The Gold Quarry Mine is a gold mine located in Eureka county, Nevada at an elevation of 5,600 feet.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Deposit): GOLD QUARRY IS ONE OF THE LARGEST GOLD DEPOSITS IN NORTH AMERICA. IT IS COMPRISED OF TWO STACKED OREBODIES: AN UPPER STRUCTURAL STOCKWORK AND A LOWER STRATABOUND REPLACEMENT. OVERALL STRIKE OF THE MAIN (UPPER) ORE ZONE IS N45E. IT IS BOUNDED ON THE WEST BY THE GOLD QUARRY AND ON THE EAST BY THE GREY/CHALLENGER FAULT SYSTEMS. MINERALIZATION IS CONTINUOUS OVER 6000 FT. OF STRIKE. MILL GRADE ORE ZONES CROSSCUT THIS TREND ON A N-S TO NW STRIKE. THE DEEP WEST OREBODY IS A SILICA REPLACEMENT ZONE AT THE CONTACT OF FOOTWALL CARBONATE ROCKS AND HANGINGWALL SILICICLASTIC ROCKS. IT AVERAGES 250 FT. IN THICKNESS, STRIKES N20E, DIPS 30-35 SE, AND AS KNOWN STRIKE LENGTH OF 2500 FT. GOLD GRADE IS DOUBLE THAT OF THE MAIN (UPPER) ORE ZONE. THE DEEP WEST ORE ZONE IS THE DOWN DIP EXTENSION OF THE MAGGIE CREEK SOUTH ORE ZONE.

Comment (Commodity): GOLD GRAINS RANGE <0.1 TO 10.0 MICRONS IN SIZE AND USUALLY OCCUR ASSOCIATED WITH MICROFRACTURES OR DISSEMINATED IN MICROCRYSTALLINE CHERTY MATRIX. AU:AG RATIO RANGES FROM ABOUT 2:1 IN MILL GRADE ORES TO 1:3 IN LEACH GRADE ORES.

Comment (Location): OPEN PIT ADJOINS MAGGIE CREEK OPEN PIT. UTM'S TO APPROXIMATE CENTER OF OPEN PIT.; PREVIOUS QUAD DESIGNATION = SCHROEDER MOUNTAIN (1968) 1:24000

Comment (Development): THE FIRST CLAIMS STAKED IN 1925 BY A. BERNING, WHO LEASED THE PROPERTY TO CUBA CONSOLIDATED MINES COMPANY. IN 1936, CUBA CONSOLIDATED SHIPPED 60 TONS OF ORE AVERAGING 0.417 OPT AU, 0.882 OPT AG. NEWMONT CORP. ACQUIRED THE PROPERTY IN 1962 AND CONDUCTED A DRILLING PROGRAM IN 1963-64 IN THE VICINITY OF WHAT IS NOW THE NORTHERN LIMIT OF GOLD QUARRY. DRILLING WAS CENTERED SW OF THE JASPEROID OUTCROP FROM WHICH THE 60 TONS OF ORE WAS MINED. FURTHER DRILLING UNTIL 1970 DELINEATED 340,000 TONS/0.12 OPT. THE LEASE AGREEMENT WAS DISCONTINUED IN 1970 DUE TO LOW GOLD PRICES AND DISCOURAGING METALLURGICAL TESTS. THE PROPERTY WAS ACQUIRED BY ROY ASH AND CHARLES THORNTON FOR $8000.00. AFTER XRF-XRD STUDIES OF GOLD QUARRY DRILL CUTTINGS SUGGESTED POSSIBLE OPEN ENDS OF MINERALIZATION, THE CLAIMS WERE REACQUIRED IN 1972. AFTER 1979, EXPLORATION DRILLING CONTINUED EAST OF THE MAGGIE CREEK OREBODY AND SIGNIFICANT AU INTERCEPTS WERE ENCOUNTERED. BETWEEN 1979 AND 1983, 550 CONVENTIONAL CIRCULATION HOLES

Comment (Workings): HISTORIC DEVELOPMENT CONSISTED OF A 40 FT. ADIT AND OTHER SCATTERED OPEN CUTS. THE CURRENT OPERATION CONSISTS OF AN OPEN PIT MINE, TWO MILLING FACILITIES, A LEACH CRUSHING PLANT, AND THREE HEAP LEACH PADS. THE DIMENSIONS OF THE ULTIMATE PIT WILL BE 1 MILE BY 3/4 MILE IN SIZE, 1200 FT. IN DEPTH. THE TOTAL MATERIAL IN THE ULTIMATE PIT IS ESTIMATED AT 576.3 MILLION TONS WHICH REFLECTS A 1.3:1 STRIP RATIO.

Comment (Development): WERE DRILLED ON 100 FT. CENTERS TO AN AVERAGE DEPTH OF 600 FT. BULK METALLURGICAL TEST SAMPLES OF MILL GRADE AND LEACH GRADE MATERIAL WERE MINED IN 1982-83. PRE-MINING BEGAN IN LATE 1983. FIRST GOLD WAS POURED IN AUGUST 1985. ; TOTAL$: 300. DEVELOPMENT CONSISTS OF A 40-FOOT ADIT, AND OTHER SCATTERED OPEN CUTS. ; ECON.COM: THE NEW SEMI-AUTOGENOUS MILL COMPLEX CURRENTLY PROCESSES MORE THAN 28,000 STPD. IN 1989, THE GOLD QUARRY PIT WAS PRODUCING 60% OF THE TOTAL MATERIAL MINED AND 62% OF THE GOLD RECOVERED BY NEWMONT GOLD COMPANY. A TOTAL OF 300 HOURLY AND SALARIED PEOPLE ARE EMPLOYED IN THE GOLD QUARRY MINE OPERATIONS GROUP.

Comment (Geology): GOLD IS PRESENT IN A GOSSAN IN QUARTZITE AND CHERT. MANY OF THE BARITE AND BASE METAL DEPOSITS IN THE MAGGIE CREEK SUBDISTRICTS ARE ASSOCIATED WITH THE GOOD HOPE FAULT SYSTEM (E.G. NEVADA STAR MINE, RECORD #M232284). THIS FAULT SYSTEM ALSO APPEARS TO LINK GOLD QUARRY AND TUSC DEPOSITS. SENSE OF MOVEMENT ON THE GOOD HOPE FAULT SYSTEM IS NOT ESTABLISHED. NORTH OF THE INTERSECTION OF THE GOLD QUARRY AND GOOD HOPE FAULTS,, AN ENTIRE RIDGE OF SILICIFIED ROBERTS MOUNTAINS FORMATION MARKS THE MARGIN OF THE CARLIN WINDOW. THE JASPEROID REPORTEDLY CARRIES SOME GOLD. GOLD QUARRY AND MAGGIE CREEK MINES ARE UNUSUAL IN THAT ORE IS HOSTED AT LEAST IN PART BY PALEOZOIC ROCKS OF THE UPPER PLATE OF THE ROBERTS MOUNTAINS THRUST.

Comment (Deposit): BECAUSE BLAST HOLES WERE BEING DRILLED ON THE DAY OF THEIR VISIT, NBMG GEOLOGISTS WERE UNABLE TO VISIT THE ACTUAL PIT AREA IN MAY, 1982.
