Comments on the geologic information

  • 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).
  • Age = Mid-Cretaceous; vein cuts schist metamorphosed during the mid-Cretaceous; see NM207.

Mining district

District name Nome

Comments on the production information

  • 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]).

Comments on the workings information

  • 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]).
