Unnamed (near headwaters of Glacier Creek)

The Unnamed (near headwaters of Glacier Creek) is a lead, zinc, and silver 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 (Reference): Primary Reference = Hudson and Wyman, 1983

Comment (Workings): Workings / Exploration = There are no workings on this occurrence.

Comment (Geology): Age = Not known

Comment (Geology): Geologic Description = A stream sediment sample in upper Glacier Creek contained 164 ppm Pb, 367 ppm Zn, and 12 ppm As (Hudson and Wyman, 1983). Follow-up reconnaissance soil sampling in the headwaters of Glacier Creek identified this occurrence. The soil sample collected here contained 51 ppm Cu, 420 ppm Pb, 1,520 ppm Zn, 10 ppm Ag, and 62 ppm As. Monument Mountain is underlain by a polydeformed metapelitic schist that may be Precambrian in age but the bedrock of Glacier Creek is a metasedimentary sequence of Lower Paleozoic age (Till and others, 1986). The Paleozoic metasedimentary rocks locally include felsic metavolcanic rocks in areas peripheral to Kiwalik Mountain. Float of very fine-grained, siliceous, tan-weathering metasediment (tuff or exhalite ?) has been observed in the headwater gravels of Glacier Creek (T. L. Hudson, unpublished data, 1982).

Comment (Deposit): Model Name = Base metal occurrences around Kiwalik Mountain may be epigenetic veins or replacements, volcanogenic massive sulfide deposits, or skarns.

Comment (Exploration): Status = Inactive
