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 (Workings): Workings / Exploration = Surface exposure only; a grab sample of a 2-foot by 6-foot sulfide rich pod assayed 3.5 ppm in gold; no other element was anomalous (Kimball and others, 1978).
Comment (Geology): Geologic Description = The area is underlain predominantly by foliated granitic rock of Cretaceous age (Brew and others, 1978). A sample of a 2-foot by 6-foot sulfide pod in granitic host contained 0.10 ounce per ton gold (3.5 ppm)--Kimball and others, 1978, location 4, fig. C41, table C36).
Comment (Geology): Age = Tertiary.
Comment (Reference): Primary Reference = Kimball and others, 1978
Comment (Deposit): Other Comments = the site is in Glacier Bay National Park and Preserve. The occurrence is south of the Tarr Inlet Knob prospect of Kimball and others (1978, fig. C41) which is in the Skagway A-6 quadrangle.
