Yankee Girl

The Yankee Girl is a tin and lead 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 (Deposit): Model Name = Vein or replacement in limestone. Not clear; possibly polymetallic replacement model (19a) or replacement tin model (14c) of Cox and Singer (1986) may apply but close analogs are not obvious.

Comment (Reference): Primary Reference = Knopf, 1908 (USGS B 358); Steidtmann, and Cathcart, 1922

Comment (Reserve-Resource): Reserves = Not defined

Comment (Workings): Workings / Exploration = A short exploratory adit was originally opened on the prospect but it had already caved by 1918.

Comment (Commodity): Gangue = iron oxide gossan

Comment (Geology): Age = the age of the mineralization is assumed to be related to the development of tin systems in the Lost River area and therefore Late Cretaceous, the age of the tin-mineralizing granites there (Hudson and Arth, 1983).

Comment (Geology): Geologic Description = This prospect is a gossanous fracture zone in Ordovician limestone peripheral to the Tin Creek granite stock (Knopf, 1908, p. 269; Sainsbury, 1969, plate 6). The gossan contains galena remnants, cerussite, arsenopyrite and some disseminated cassiterite (Seidtmann and Cathcart, 1922, p. 80). Anderson (1947) reported a sample assay that ran 0.02 opt gold, 0.6 opt silver, 3.1% lead, and 0.47% tin.

Comment (Exploration): Status = Inactive
