Hippie Creek

The Hippie Creek is a zinc, 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 (Deposit): Model Name = Polymetallic vein (Cox and Singer, 1986; model 22c).

Comment (Deposit): Other Comments = the Hippie Creek prospect may be controlled along a high angle structure that also hosts the Veleska-South (MG050) prospect about 11 kilometers to the north.

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

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

Comment (Workings): Workings / Exploration = The Hippie Creek occurrence was found and investigated by the late Bruce Reed during regional geological investigations conducted by the U.S. Geological Survey in the southern Alaska Range (Reed and Elliott, 1968, C 596). Sampling by the Anaconda Minerals Company, who referred to the site as the Post River #2 prospect, reported a 5.0 meter true width that averaged 0.7 percent copper, 12.7 percent lead, 10.5 percent zinc, and 587.8 grams/tonne silver (Brewer and others, 1992). Selected samples collected by Reed and Eliott (1968, C 596) contain up to 686.0 grams/tonne silver, 500 ppm cadmium, 0.30 percent copper, 7.00 percent lead, 300 ppm antimony, and 10.00 percent zinc.

Comment (Geology): Age = Unknown; thought to be Tertiary by Bundtzen, Kline, and Clough (1982) and Bundtzen, Harris, and Gilbert (1997).

Comment (Exploration): Status = Inactive

Comment (Geology): Geologic Description = The Hippie Creek occurrence contains pyrite, sphalerite, and argentiferous galena in scattered grains and discontinuous bands 2 to 25 cm wide, and found in a steep bedrock canyon where calcite-epidote veins cut limestone near the faulted contact between the Terra Cotta Mountains Sandstone and Barren Ridge Limestone of the Dillinger subterrane (Bundtzen, Harris,and Gilbert, 1997). The sulfide-rich vein also contains minor arsenopyrite.? the vein ranges from 6 inches to 6 feet wide and is obscured by talus on both sides of a steep canyon. Dike swarms and small stock-like bodies of porphyritic felsic rocks occur north of the limestone (Reed and Elliott, 1968, C 596). Sampling completed by Anaconda Minerals Company, who referred to the site as the Post River #2 prospect, contained a true width of 5.0 meters averaging 0.7 percent copper, 12.7 percent lead, 10.5 percent zinc, and 587.8 grams/tonne silver (Brewer and others, 1992). Grab samples of surface mineralization reported by Reed and Elliott (1968, C 596) contain up to 686.0 grams/tonne silver, 500 ppm cadmium, 0.30 percent copper, 7.00 percent lead, 300 ppm antimony, and 10.00 percent zinc.
