The Brink (Molybdenum Mountain) is a molybdenum mine located in Alaska.
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.

Comments
Comment (Reference): Primary Reference = Hoare and Cobb, 1977
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Cretaceous or Tertiary . The granitic rocks may be part of a Cretaceous or Tertiary igneous assemblage that is widespread through southwest Alaska. The country rocks to the stock are clastic sedimentary rocks that may be part of the mid-Cretaceous Kuskokwim Group (Hoare and Coonrad, 1959) or possibly an older Paleozoic or Mesozoic section correlative with the Gemuk Group (Bundtzen and Laird, 1991).
Comment (Deposit): Model Name = Porphyry Mo? (Cox and Singer, 1986; model 21b)
Comment (Geology): Geologic Description = Float specimens from this location contained molybdenite and powellite (?) in quartz (Smith, 1942). Hoare and Coonrad (1959) show a prospect symbol in a granitic stock at this location. The granitic stock may be part of a Cretaceous or Tertiary igneous assemblage that is widespread through southwest Alaska. The country rocks to the stock are clastic sedimentary rocks that may be part of the mid-Cretaceous Kuskokwim Group (Hoare and Coonrad, 1959) or possibly an older Paleozoic or Mesozoic section correlative with the Gemuk Group (Bundtzen and Laird, 1991).
