Lantern-Bullion Monarch Mines Area

The Lantern-Bullion Monarch Mines Area is a gold mine located in Eureka county, Nevada at an elevation of 6,053 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.

Comment (Commodity): Gangue Materials: quartz

Comment (Deposit): The Lantern and Bullion Monarch orebodies are Carlin-type gold deposits in the central Carlin trend. The Lantern, West Carlin, and Perry (Peregrine) deposits are aligned along the N50W strike of the Castle Reef fault. Most of the gold occurs in a zone at the base of the pit where 2 or more north-trending faults intersect. This zone curves to the west in the base of the pit and is truncated at its north end by a cross-cutting structure which is apparently unmineralized. Deposit is tightly structurally controlled. Gold occurs in the fault gouge associated with arsenic, and silicification and jasperoid development. Mineralizing fluids are thought to be post-faulting, having traveled along pre-existing fracture system.

Comment (Development): Active stripping of waste rock was under way in 1982

Comment (Economic Factors): Reserves for the Bullion Monarch in 1987 were 1 million tons of ore grading 0.10 ounces of gold per ton. One source says that from 1977?84, the Bullion Monarch mine produced 17,779 ounces of gold, and another sources says that the mine produced 34,500 ounces of gold, from 1979-1982. In 2002, the South Lantern orebody was reported to contain a pre-mining 200,000 ounces of gold, the North Lantern orebody, 100,000 ounces of gold, and the Exodus orebody, 400,000 ounces of gold, for a total 700,000 contained ounces of gold for the Lantern orebodies. Production for the Lantern and satellitic deposits were combined with those of Carlin and Pete deposits of Newmont and not available individually.

Comment (Identification): This record encompasses deposits described individually by earlier records RE00282 and M231432, M231429, RE00285, RE00283, W700376 and other nearby oreodies not described in MRDS records

Comment (Workings): open pits

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.
