Geologic structures

Type of structure Regional
Structure 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 on the geologic information

  • 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.

Comments on the workings information

  • at least one open pit

Comments on other 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.

Comments on 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.
