Osceola District Lode Deposits

The Osceola District Lode Deposits is a gold and tungsten mine located in White Pine county, Nevada at an elevation of 7,612 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: 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.

Comments

Comment (Deposit): In general, the Osceola lode deposits consist of sheeted quartz veins cutting quartzite and altered limestone adjacent and related to a quartz monzonite to- granodiorite porphyry stock and associated dikes. Scheelite and coarse gold occur both in the quartz veins, in altered limestone adjacent to the veins, and also disseminated in beds of finely shattered quartzite. In the vicinity of the Cumberland Lode, there are at least 5 adjacent parallel fissures forming a sheeted zone, with 2 main parallel lodes several hundred feet apart. Vein material contains many vugs lined with fluorite, gold, and other minerals. There is a large vein of tungsten carrying gold values running N-S across the western end of the Hampton Group. Veins are oriented both E-W and N-S and are intimately associated with several parallel fracture zones. Scheelite occurs as large orange-brown crystals up to several inches across, and can also occur as small specks and crystal clusters surrounding small iron-stained cavities in the quartz. Scheelite occurs in several narrow steeply dipping quartz veins in granite. A considerable amount of lead ore was found in a vein parallel to the lower Tunnel vein. Host rock is predominantly massive bedded Cambrian quartzite striking N10E, dipping 45NW.

Comment (Economic Factors): The camp produced nearly $5 million, primarily in gold, with some silver, lead and tungsten. Intermittent mining continues. Reported production in 1939 was $175,000 worth of gold. Reported production in 1940: was 5,884 ounces of gold and 55 ounces of silver. Production from 1936 to 1942 totalled about 37 Kilotonnes of ore containing 30,000 ounces of gold and 15 ounces of silver.

Comment (Identification): This record incorporates material from several records of the major lode deposits in the Osceola District.

Comment (Development): Lode gold was discovered in the Osceola District in 1872, and most of the vein deposits were first worked for gold, with the early ore milled in arrastras. Some exceptionally high grade " ore was taken out of the Hampton Group in 1896. A small cyanide plant was built in the early 1900s and a mill run of several hundred tons of ore was made from the Cumberland Mine before 1908. Some of the mines lapsed and were inactive until 1927-1928, when scheelite was identified in the veins. Parker owned and operated the Dirty Shirt Mine from 1929-1933 and mined and milled about 5 tons high-grade scheelite concentrate, after which Uvada Tungsten was organized to take over the property, but the lease lapsed due to low price for tungsten. The Black Mule (Pony Express) mine was first worked for gold in the late 1800's. Tungsten was discovered about 1930, after which it was operated for a short time by the Nevada-Massachusetts Co., and later in 1942-43 by the Gilded Age Mining Co. There was renewed exploratio and development of both the lode and placer properties of the district in the 1980's. In 1997 it was reported that Alta Gold Co. had an agreement with Osceola Gold Mining Co. to develop gold properties covering about 730 hectares in the Osceola district. Alta Gold?s initial drilling was focused in the area around the old Gilded Age (Black Mule, Pony Express) Mine.

Comment (Location): The gold-tungsten-bearing quartz belt found in 1872 cut across Pilot Knob, a spur on the NW flank of the Snake Range.

Comment (Workings): The Gold Exchange Group/Cumberland Mine claims have the most extensive underground workings of the district including 2 shafts, several stopes, and winzes. Other district mine workings include many shafts and adits with thousands of feet of drifts, crosscuts and raises on several levels. More recent work since 1980 has been mostly shallow surface cuts and drilling. A 20-stamp mill was present in 1922.

Comment (Commodity): Ore Materials: gold, scheelite, powellite

Comment (Commodity): Gangue Materials: quartz, fluorite, iron oxides, calcite, limonite, dendritic manganese, manganite.

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.
