The Unnamed (north side of North Fork, Mosquito Creek) is a zinc and antimony 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 (Workings): Workings / Exploration = None are known, some shallow hand dug prospecting pits may be locally present in this area.
Comment (Deposit): Model Name = Sulfide veins and/or replacements in carbonate rocks
Comment (Geology): Geologic Description = Miller and Grybeck (sample 7, 1973) collected a grab sample of gossan developed at a marble/schist contact at this locality. This sample contained 7,000 ppm As, 700 ppm Cu, 70 ppm Mo, 3,000 ppm Pb, 10,000 ppm Sb, and 10,000 ppm Zn. These occurrences are in Lower Paleozoic or Precambrian high grade metasedimentary rocks (Till and others, 1986).
Comment (Geology): Age = Cretaceous ; Epigenetic mineralization in metamorphic rocks of Seward Peninsula is primarily of Cretaceous age.
Comment (Reference): Primary Reference = Miller and Grybeck, 1973
Comment (Exploration): Status = Inactive
