Willard Gold Mine

The Willard Gold Mine is a gold and silver mine located in Pershing county, Nevada at an elevation of 4,987 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.

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 (Workings): There were numerous old underground and surface workings in the current mine area and at historic mines to the north and east of the mined area. These include numerous adits, tunnels, shafts, open stopes, cuts, and scattered workings. 1990s development consisted of drill sites and several open pits. The mine site has now been reclaimed. At the old Johnson-Heizer mine about 2 miles to the north, the deposit was developed by a 264-ft inclined shaft from which some 440 feet of drifting and considerable stoping were done, and other historic mines in the district had a considerable amount of underground development.

Comment (Development): The historic antimony mines in the area were worked from about 1915 until about 1950. The area was explored for gold deposits beginning in the 1970s and several drilling programs were active in the area. Western States Minerals Corporation discovered a mineable gold deposit in the 1980s. The Willard deposit of Western States Minerals Corporation was placed into production in May 1990, and was reportedly mined out by 1993, but production amount was not reported. In 1997, in the Willard district, Easton Minerals elected to proceed with the second year of an exploration agreement on its Colado gold-silver property after obtaining encouraging results from the first phase of drilling. Previous work on the project by owner Santa Fe Pacific Gold Corp. indicated an oxide gold resource of 15 million tons grading 0.022 opt. Easton Minerals, Ltd. sti owned the property in 1999, but later dropped the property. Exact location of the Colado deposit is unknown, but it is thought to be near (within a mile or two) of the willard Mine area.

Comment (Economic Factors): Pre-production reserves in 1989 were reported to be 3.61 million tons of ore. Reserves in 1989 were reported to be 15 million tons of ore grading 0.022 opt gold. From 1990 to 1993, the Willard Gold Mine produced gold, but the production amount was not reported. In 1997, at a Willard District property apparently located a few miles to the north, Colado Gold reported reserves of 15 million tons of ore grading 0.022 OPT gold, later transferred to Easton Minerals, Ltd. (1999), which later dropped the property.

Comment (Identification): This is a new record for the recently mined Willard gold mine, but includes some data from earlier records for the historic Willard District antimony mines: M242911, M060396, M242912, M060395

Comment (Location): The Willard gold mine is located at the north end of the West Humboldt Range, about 2 miles due east of the Young Ranch.

Comment (Commodity): Ore Materials: free gold

Comment (Commodity): Gangue Materials: quartz, iron oxides, pyrite, Mn oxide, hematite, variscite, fluellite, wavellite

Comment (Deposit): The northern portion of the deposit consisted of a stockwork network of quartz veinlets in limestone at and near the contact with underlying rhyolite. Mineralization is also present in brecciated rhyolite close to basalt dikes. There is a zone up to 2 meters wide of anastomosing quartz and calcite veinlets and stringers that dips 50-55W. There is some hydrothermal breccia with abundant pyrite. Late-stage green fluorite and very late barite are present. Pyrite is the only visible sulfide mineral. Ore consisted of free-milling gold and silver in copper-stained quartz veins.. In the southern portion of the deposit are a number of E-W-trending hydrofractured breccia zones with anastomosing quartz veinlets cutting interbedded phyllite and sandstone, with iron oxides after pyrite. The quartz is well crystallized, commonly vuggy, with crystals forming rosettes around breccia fragments. There is a quartz vein with breccia and jasperoid along shear zone. There is an extensive stockwork zone of veins, silicification, and iron-staining in phyllite. Ore is controlled by a vertical shear zone.
