The Bida Mine is a gold mine located in White Pine county, Nevada at an elevation of 6,972 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.

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.

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.

Description: The Bald Mountain district is located in an area of thinned crust along the eastern side of the Late Proterozoic rift that split the North American craton. It is also in the west-central portion of the Late Devonian-Early Mississippian Antler foreland basin, and near the eastern edge of deformation related to the late Paleozoic Humboldt orogeny To the west of the Bald Mountain district, geologic interpretations are dominated by recognition of Paleozoic deformation, whereas to the east, interpretations emphasize Mesozoic contraction and plutonism and Tertiary extension.

Comments
Comment (Identification): The Bida deposit is encompassed by Placer Dome?s Mooney Basin mine area.
Comment (Location): The Bida deposit is located on the eastern flank of Little Bald Mountain about a mile northwest of the Saga pits.
Comment (Workings): at least one open pit
Comment (Commodity): Ore Materials: gold
Comment (Deposit): The Bida Trend strikes N40-50W. The deposit is hosted in the Pilot Shale and is generally of lower grade than most other Bald Mountain deposits.
Comment (Development): When mined, the ore from the Bida and Saga deposits deposits will be processed at the Mooney Basin facility along with ore from the Top deposit. In 2006, Barrick Gold Corp. acquired the Bald Mountain Mine properties through its acquisition of Placer Dome U. S., Inc.
Comment (Economic Factors): No reserves reported as yet, but the deposit is included in Placer Dome?s current mine plan (2004). When mined, ore from the Bida and Saga deposits will be processed at the Mooney Basin facility along with ore from the Top deposit.
Comment (Geology): Jurassic or older structures that predate the Bald Mountain Stock include west to northwest-striking faults and at least some attenuation faults. The 159 Ma Bald Mountain pluton was emplaced along a pre-existing west-to northwest-striking structure and the pluton cuts some attenuation faults. Reverse faults and north-trending folds formed during Mesozoic compressional deformation that was related to pluton emplacement or Sevier-age (Cretaceous to early Tertiary) deformation. Major west-to northwest-striking faults cross the range, separate the range into domains, and were repeatedly activated. During Mesozoic compression, they acted as strike-slip tear faults. During Tertiary extension, these faults partly controlled rotation and down-dropping of rocks to the west, east, and south. The most prominent of these features is the Bida trend of Bald Mountain which controlled emplacement of the Jurassic Bald Mountain pluton. The Bida trend is most commonly made up of high angle faults and, along the southern side, slightly to moderately dipping faults. The apparent offset is normal, but is interpreted as at least partly strike-slip.

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.
