Juniper Mine

The Juniper Mine is a mercury mine located in Pershing county, Nevada at an elevation of 5,200 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 (Location): 2 MI. N OF PERSHING MINE; PREVIOUS QUAD DESIGNATION = LOVELOCK 1:62500

Comment (Deposit): DISCOVERED IN 1923 BY E.M. BENEDICT. BOUGHT IN 1927 BY L.A. FRIEDMAN (NEVADA QUICKSILVER COMPANY) AND MINE BECAME ONE OF THE LEADING PRODUCERS IN THE COUNTRY DURING 1928-1929. MINE WAS LEASED TWICE BETWEEN 1931 AND 1942. NO EORT MADE TO DEVELOP MINE AFTER 1943. THE WORKINGS ARE IN BEDS OF UPPER TRIASSIC LIMESTONE CONGLOMERATE AND OVERLYING SHALE. A PROMINENT EASTERLY TRENDING FAULT WHICH OFFSET THE LIMESTONE SHALE CONTACT WAS IMPORTANT IN LOCALIZING THE MAJOR ORE BODY. DEPOSITION OF CINNABAR OCCURRED IN OTHER DIVERGING STEEP FAULTS. ; INFO.SRC : 1 PUB LIT

Comment (Development): BOUGHT IN 1927 BY L.A. FRIEDMAN (NEVADA QUICILVER COMPANY) AND MINE BECAME ONE OF THE LEADING PRODUCERS IN THE COUNTRY DURING 1928-29. MINE WAS LEASED TWICE BETWEEN 1931 AND 1942. NO EFFORT WAS MADE TO DEVELOP MINE AFTER 1943.

Comment (Other Database): 3,259 FLASKS TO END OF 1943; 1016/TON

Comment (Production): TO END OF 1943; 10 LB/TON

Comment (Geology): CINNABAR OCCURRED IN LIMESTONE AS VERY RICH BUNCHES AND PODS AND ALSO FORMED DISSEMINATED CRYSTALS IN WHITE CALCITE VEINLETS CUTTING THE LIMESTONE. SOME OF ORE FROM UPPER PARTS OF THE MINE CONTAINED STIBNITE AND IN THE LOWER LEVELS SCATTERED PODS OF ORE CONTAINED A HIGHER PERCENTAGE OF STIBNITE. BOTH THE ORE BODIES LAY IN THE LIMESTONE CONGLOMERATE CLOSE BENEATH THE CONTACT, IN PLACES COMING IN DIRECT CONTACT WITH THE SHALE. THE LARGEST ORE BODY IS LOCALIZED BETWEEN TWO INTERSECTING STEEP FAULTS. MINERALIZATION OCCURS IN LIMESTONE BENEATH SHALE AND ADJACENT TO A FAULT THE DEPOSITS ARE FOLDED AND FAULTED INTO NW TRENDING RIDGES. SOUTH PART OF AREA IS FANGLOMERATE, NORTH PART HAS BASALTS. ; MAJOR.UNITS: UPPER TRI AND LOWER JUR SEDIMENTARY ROCKS

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.
