The Homestake Mine is a gold and silver mine located in Lincoln county, Nevada at an elevation of 7,080 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.
Elevation: 7,080 Feet (2,158 Meters)
Commodity: Gold, Silver

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.
Homestake Mine MRDS details
Primary: Homestake Mine
District: Eagle Valley (Fay, Gold Springs) District (Fay, Gold Springs) District
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.
Record Type: Site
Operation Category: Past Producer
Deposit Type: Vein
Operation Type: Unknown
Years of Production:
Deposit Size: S
Mineral Deposit Model
Model Name: Epithermal vein, Comstock
Description: N-S And E-W Vein Systems
Description: Fault Is Probably Pre-Mineral, For Although Slicks Are Present On Footwall, Vein Is Relatively Unbrecciated.
Alteration Type: L
Alteration Text: Chloritization, Silicification, Silicification
Analytical Data: SAMPLES 1727 AND 1728 CONTAIN, RESPECTIVELY: 200 PPM MN, 50 AND 5 PPM AG, 20 AND 0 PPM AU, 200 AND 500 PPM BA, 0 AND 100 PPM MO, 20 AND 50 PPM PB, 0 AND 200 PPM SR, 10 AND 100 PPM V, 0 AND 100 PPM ZR.
Comment (Deposit): OPEN-CENTERED FISSURE VEINS AND VEINLETS WHICH CARRY PYRITE. THE HANGING WALL AND FOOTWALL ANDESITES ARE IRON-STAINED, BLEACHED, SILICIFIED, AND HEAVILY QUARTZ-VEINED. THE ROCKS ARE NOTABLY BRECCIATED (SLICCKS ARE ABUNDANT) AND SHOW A NETWORK OF CRUSTIFORM QUARTZ VEINS AND VEINLETS WHICH EXTEND OUTWARD INTO THE WALLROCK ADJACENT TO THE MAIN VEIN. QUARTZ VEINING OF WALLROCKS INCREASES WIDTH OF VEIN EXPOSURE TO 10 FT OR MORE. MAIN VEIN IS SHEARED BY SEVERAL SMALL E-W STRUCTURES AND MAY BE TRUNCATED BY ONE SUCH STRUCTURE AT THE SOUTHERN END OF THE EXPOSURE.
Comment (Workings): GLORY HOLE OR STOPE FOLLOWS VEIN STRUCTURE FOR SEVERAL HUNDRED FEET. SHORT SHAFTS ARE INCLINED ALONG VEIN AT WEST EDGE OF STOPE. STOPE IS ABOUT 10-15 FT DEEP. THERE ARE OTHER SHAFTS AND SHALLOW WORKINGS IN THE AREA, BUT THEY ARE NOT VERY EXTENSIVE.
Comment (Geology): CRUSTIFIED EPITHERMAL QUARTZ VEIN, WITH CHALCEDONIC AND COMB QUARTZ YELLOWISH ANDULARIA, LAMECLAR CARBONATE. MERCURY RECOVERED BY PANNING
Comment (Development): NO ACTIVITY AT TIME OF EXAMINATION IN 1983, BUT AREA NEAR MINE IS STAKED.
Comment (Deposit): CRUSTIFIED EPITHERMAL QUARTZ VEIN WITH ADULARIA (ALUNITE ?) APPEARS TO HAVE BEEN EMPLACED ALONG A SHEAR ZONE. UPPER PORTION OF EXPLORED VEIN CONSISTS OF MASSIVE TO COCKADE QUARTZ WHICH ENCASES SILICIFIED ANDESITE AND POSSIBLY SOME RHYOLITE FRAGMENTS WHICH WERE PROBABLY RIPPED UP AND INCORPORATED IN VEIN DURING EMPLACEMENT. MAIN VEIN IS A MASSIVE TO BANDED, SUGARY TO CHALCEDONIC GREENISH WHITE QUARTZ-ADULARIA (?) VEIN OVER 5 FT WIDE. MOST QUARTZ IS VERY FINE-GRAINED AND TYPICALLY FORMS UNDULATORY CHALCEDONIC BANDS PARALLEL TO THE VEIN. SOME OF THE BANDS ARE DARK WITH FINELY DISPERSED SULFIDES WHICH ARE PROBABLY AG-BEARING MINERALS, AND IN SEVERAL SAMPLES, VERY FINE-GRAINED FREE GOLD WAS NOTED IN THE SULFIDE-RICH LENSES. GOLD ALSO OCCURS WITH PYRITE, MINOR CHALCOPYRITE AND BLUE METALLIC SULFIDES IN FINE-GRAINED CLOTS DISPERSED RANDOMLY THROUGHOUT SUGARY QUARTZ VEIN IN DUMP SAMPLES AND IN OUTCROP. THE GOLD-BEARING FINE-GRAINED QUARTZ VEIN IS CROSSCUT BY LATE-STAGE CLEAR VITREOUS

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 at Gold Districts of Nevada.
