Hippie Creek-South

The Hippie Creek-South is a silver 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 (Exploration): Status = Inactive

Comment (Reference): Primary Reference = Reed and Elliott, 1968 (C 596)

Comment (Reserve-Resource): Reserves = None known.

Comment (Workings): Workings / Exploration = The Hippie Creek-South occurrence was found and investigated by the late Bruce Reed during regional geological investigations in the southern Alaska Range by the U.S. Geological Survey (Reed and Elliott, 1968, C 596). Selected analyses contain greater than 1,000 ppm arsenic, greater than 0.50 percent lead, 0.30 percent antimony, and greater than 1.0 percent zinc.

Comment (Deposit): Model Name = Lead-zinc skarn deposit (Cox and Singer, 1986; model 18c).

Comment (Deposit): Other Comments = Peripheral to Bowser Creek-Main (MG068), Bowser Creek-Northeast (MG067), and Bowser Creek-Headwaters (MG066) prospects.

Comment (Geology): Geologic Description = According to Reed and Elliott (1968, C 596), the Hippie Creek-South occurrence consists of locally abundant calcite, pyrite, and galena and minor to trace sphalerite and stibnite (?) in several 2 to 8 cm thick shear zones in limestone of the Terra Cotta Mountains Sandstone, a formation of the lower Paleozoic Dillinger subterrane (Bundtzen and others, 1988, 1997). The mineralized shear zone is parallel to a 6 m thick, pyrite-bearing felsite porphyry dike swarm (Bundtzen and others, 1988). The dikes are undated but a similar plutonic suite to the south yielded a 60.5 Ma age (Solie and others, 1991). The shear zone is discontinuously mineralized.? Analyses cited in Reed and Elliott (1968, C 596) contained greater than 1,000 ppm silver, 1,000 ppm arsenic, greater than 0.50 percent lead, 0.30 percent antimony, and greater than 1.00 percent zinc.

Comment (Geology): Age = Unknown; inferred to be mid-Tertiary, based on isotopic age dating of nearby genetically related plutonic rocks (Solie and others, 1991).
