The Frozen Creek is a copper and gold 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 = Active
Comment (Deposit): Model Name = Porphyry Cu-Au (Cox and Singer, 1986; model no. 20c)
Comment (Deposit): Other Comments = See Tarn (MD027), Pork Chop (MD031), Mystery Mt. East (MD028), and Copenhagen Hill (MD030) prospects. The Frozen Creek Prospect is on land selected or owned by Doyon Ltd. For additional information contact Doyon Ltd. at 210 1st Ave., Fairbanks, Alaska, 99701.
Comment (Reference): Primary Reference = DiMarchi and others, 1997
Comment (Workings): Workings / Exploration = The Frozen Creek prospect was found during regional exploration conducted by WGM Inc. in 1977 (Andrews, 1978). ACNC worked on the prospect from 1988 to 1990, and ASA Inc. continued work through 1997 (DiMarchi and others, 1997). During 1989-1991, American Copper and Nickel Inc. explored the area as a porphyry copper-gold target. ASA Inc. continued exploration work with the same target in mind during 1995 and 1996. Two grab samples reported by Clautice and others (1993) averaged 585 ppm copper and 2.1 ppm silver.
Comment (Geology): Age = the Frozen Creek prospect is inferred to be Late Cretaceous based on isotopic age of Mystery Mountains intrusive complex (Moll and others, 1981).
Comment (Geology): Geologic Description = The Frozen Creek prospect consists of a large zone of boron metasomatism in the eastern edge of the Mystery Mountains Pluton. It is the eastern-most porphyry-like prospect in a seven mile (11 km) long northeast-trending zone of similar prospects that cut across the central Mystery Mountains. The Frozen Creek prospect is inferred to be Late Cretaceous based on isotopic age of Mystery Mountains intrusive complex (Moll and others, 1981). A strong copper-gold soil anomaly was detected at Frozen Creek (DiMarchi and others, 1997), which is part of the core of Cu-Au anomalies that are surrounded by a lead-zinc mineral zonation. Disseminated chalcopyrite and pyrrhotite are found throughout a tourmaline-enriched monzonitic plutonic rocks; little mineralization is noted in host biotite hornfels. Malachite is locally abundant in hairline fractures in small intrusive bodies. The mineralized zone at Frozen Creek is at least 1,500 feet (457 m) in diameter. Two grab samples of mineralization collected by Clautice and others (1993) averaged 585 ppm copper and 2.1 ppm silver.
