The Whistler is a copper, barium-barite, gold, zinc, 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.

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 (Commodity): Gangue = Carbonate
Comment (Deposit): Model Name = Gold-copper porphyry system(?) or feeder to a volcanogenic system(?)
Comment (Deposit): Other Comments = Volcanic lithologies may be same age as the volcanic rocks mapped by Reed and Nelson (1980) in the Long Lake Hills to the northeast.
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Unknown age but cut Tertiary or possibly Cretaceous host rocks.
Comment (Geology): Age = Host rock is Tertiary - Cretaceous.
Comment (Reference): Primary Reference = Reed and Elliott, 1970; Bundtzen and others, 1989
Comment (Workings): Workings / Exploration = Exploration work included: silt sampling, mapping, rock chip geochemical sampling, grid soil sampling, grid VLF, magnetic and IP geophysical surveys, and diamond drilling (Cominco American Incorporated, unpublished reports, 1987-1990).
Comment (Geology): Geologic Description = At this locality fine-grained feldspar-hornblende porphyritic hypabyssal andesite intrudes undifferentiated sedimentary rocks of the Mesozoic Kahiltna terrane and/or the Tertiary Matanuska Formation. Mineralization, contained within the intrusive rocks, includes stockwork chalcopyrite-quartz-magnetite with elevated gold values; vein and joint controlled sulfide-barite-silica mineralization; and chalcopyrite with minor sphalerite in silcified andesite. The prospect is defined by a 500 foot by 800 foot, circular magnetic high (Cominco American Incorporated, unpublished reports, 1987-1990). Bundtzen and others (1989) reported a large, low-grade gold and base metal resource with a 300 foot drill intercept of 0.22% copper and 0.033 oz/ton gold. Unknown age. Tertiary(?) or possibly Cretaceous.
