The Candle-East is a copper, 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 = Bundtzen and Laird, 1983
Comment (Deposit): Model Name = Polymetallic vein (Cox and Singer, 1986; model 22c).
Comment (Geology): Age = Chronological age is for nearby Candle monzonite pluton.
Comment (Geology): Age = Unknown; inferred to be Late Cretaceous based on 70 Ma K-Ar age reported for nearby Candle monzonite pluton by Bundtzen and Laird (1983).
Comment (Workings): Workings / Exploration = The occurrence area has been used as road metal for local road construction and is fairly well exposed. Two chip channel samples taken across the strike of the mineralization contained up to 2.23 grams/tonne silver, 169 ppm copper, 130 ppm lead, and 246 ppm zinc.
Comment (Geology): Geologic Description = The Candle-East occurrence consists of a densely concentrated zone of ferricrete-tourmaline veins and stockwork in a brecciated hornfels aureole adjacent to the Late Cretaceous, Candle volcanic-plutonic complex (Bundtzen and Laird, 1983). The zone trends northeast and dips steeply to both the southeast and northwest. The mineralization covers a 100 meter by 15 meter area. A trace of chalcopyrite was observed in one hand specimen. Two chip-channel samples taken across the strike of the mineralization contained up to 2.23 grams/tonne silver, 169 ppm copper, 130 ppm lead, and 246 ppm zinc.
