The Widstedt (Anvil Creek) is a antimony 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 (Geology): Geologic Description = The Widstedt prospect lies within or near the Anvil Creek fault and related shear zones that are as much as 120 feet wide. The deposit consists of quartz-calcite veins that contain arsenopyrite, pyrite, and locally stibnite. The veins commonly cut schist or are localized in shear zones (Collier and others, 1908; Brooks, 1916; Mertie, 1918 [B 662-I, p. 425-449]; Cathcart, 1922). Pyrite and arsenopyrite also are disseminated in schist adjacent to the veins, and some sulfide-rich zones are as much as 15 feet wide. Stibnite lenses with little quartz occur at this prospect and some stibnite ore has reportedly been produced (Mertie, 1918 [B 662-I, p. 425-449]; Cathcart, 1922). Material from a dump next to a water-filled shaft consisted of finely crystalline stibnite associated with pyrite and arsenopyrite in small veinlets cutting quartz and schist. An open cut exposed a 12 foot-wide zone of quartz stringers cut by veinlets of finely crystalline stibnite. The Anvil Creek fault is a through-going high-angle structure that inthis area juxtaposes different types of graphitic schist and dark graphitic quartzite in this area (Hummel, 1962 [MF 247]). Bedrock is mostly graphitic schist, probably of early Paleozoic protolith age (Hummel, 1962 [MF 247]; Sainsbury, Hummel, and Hudson, 1972 [OFR 72-326]; Till and Dumoulin, 1994; Bundtzen and others, 1994).
Comment (Geology): Age = Mid-Cretaceous; vein cuts schist metamorphosed during the mid-Cretaceous; see NM207.
Comment (Production): Production Notes = A small amount of antimony ore is reported to have been mined from the Widstedt prospect (Mertie, 1918 [B 662-I. p. 425-449]).
Comment (Exploration): Status = Active?
Comment (Reference): Primary Reference = Cathcart, 1922
Comment (Workings): Workings / Exploration = An exploration shaft was filled with water by 1920; some open-cut surface workings are also present (Cathcart, 1922). In 1916, the total length of underground workings on lode gold prospects in Anvil Creek valley was several hundred feet (Mertie, 1918 [B 662-I, p. 425-449]).
Comment (Deposit): Model Number = 36a, 27d?
Comment (Deposit): Model Name = Low-sulfide Au-quartz veins (Cox and Singer, 1986; model 36a) and/or possibly simple Sb deposits (Cox and Singer, 1986; model 27d).
