Unnamed (on Alder Creek)

The Unnamed (on Alder Creek) is a gold 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.

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 (Exploration): Status = Probably inactive

Comment (Workings): Workings / Exploration = Some surface workings and shallow exporation to depth of 60 feet has been noted.

Comment (Reference): Primary Reference = Collier and others, 1908

Comment (Reserve-Resource): Reserves = Not defined

Comment (Geology): Geologic Description = This is a lode prospect initially exposed on lower Alder Creek by placer operations and subsequently explored to a depth of 60 feet from exposures on the south side of the creek. The prospect is an altered fault (?) zone, in one place 16 feet wide, along a contact between schistose carbonate rocks in the hanging wall and metapelitic rocks in the footwall (Collier and others, 1908, p. 279-280). The altered zone is a talcose material with quartz stringers and blebs, pyrite, and fine gold. A sample assayed 0.06 opt gold and a trace of silver (Collier and others, 1908).??

Comment (Commodity): Gangue = talcose altered material

Comment (Deposit): Model Name = Altered fault (?) contact with quartz stringers, pyrite, and fine gold. Possibly low sulfide Au-quartz vein model (Cox and Singer, 1986, model 36a).

Comment (Geology): Age = Not known; apparently post-dates regional deformation and metamorphism which is Late Jurassic/Early Cretaceous in age.
