Geologic information

Identification information

Deposit ID 10308408
Record type Site
Current site name Yankee Girl

Geographic coordinates

Geographic coordinates: -167.1344, 65.46027 (WGS84)
Relative position The Yankee Girl prospect is located on the north side of Tin Creek valley at an elevation of 900 feet. It is 700 feet west of the contact of the Tin Creek stock (see Sainsbury, 1969, plate 6). Tin Creek is an east tributary to Lost River whose confluence is located 4.5 miles upstream from the mouth of Lost River on the Bering Sea. This is locality 9 of Cobb and Sainsbury (1972). Cobb (1975) summarized relevant references under the name 'Yankee Girl'.

Comments on the geologic information

  • 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.
  • 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).
