Temby

The Temby is a copper 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 = Placer gold claims have been reported in the Temby area, but Degenhart and others (1978) observed no placer activity. A mineralized sample was collected by the U.S. Geological Survey (Brosge and others, 1967). Four rock samples were collected and analyzed and a geologic sketch map was made by Degenhart and others (1978).

Comment (Geology): Age = Mid-Paleozoic.

Comment (Deposit): Model Name = Sulfide-bearing quartz veins cutting phyllite.

Comment (Geology): Geologic Description = The country rocks in this area consist of Paleozoic clastic strata that are bounded to the north and east by mid-Paleozoic carbonates and to the south and west by metamorphic and calcareous clastic rocks (Schmidt and Allegro, 1988). The northeast trending Paleozoic clastic belt assumes a northerly trend in this area. At the Temby occurrence, gray, graphite-chlorite-quartz phyllite hosts quartz veins. The attitudes of the phyllite are quite variable, probably due to small-scale folding. The deposit consists of pyrite, chalcopyrite and malachite associated with quartz veins. The sulfides occur as discontinuous stringers and small blebs. Distribution of quartz rubble indicates that three mineralized quartz veins are present within a zone 200 feet wide. The veins vary from 6 inches up to 3 feet in thickness and can be traced up to 250 feet along strike. Four rock samples were analyzed. The average values were 1.1% Cu, 0.07 ounce Ag per ton, and trace amount of Au (Degenhart and others, 1978).
