Identification information

Deposit ID 10308002
Record type Site
Current site name Scotia (Anvil Creek)

Geographic coordinates

Geographic coordinates: -165.40267, 64.57778 (WGS84)
Relative position The Scotia prospect is at an elevation of about 250 feet on the northwest side of Anvil Creek, and its about 300 feet southwest of the Snake River road switchback where it crosses Anvil Creek. The prospect is locality 16 of Hummel (1962 [MF 247]). The map location is just inside the east-central boundary of section 35, T. 10 S., R. 34 W., Kateel River Meridian; it is probably accurate to within 500 feet.

Comments on the geologic information

  • Geologic Description = The Scotia prospect is probably within sheared wallrock near the Anvil fault. Cathcart (1922, p. 239) reported that an 8-inch quartz-calcite vein occured in a short tunnel on the Scotia claim; pyrite and arsenopyrite were present in both schist and vein material. Bedrock in the general area is mostly graphitic schist, probably of early Paleozoic protolith age (Hummel, 196 [MF 247]; Sainsbury, Hummel, and Hudson, 1972 [OFR 72-326]; Till and Dumoulin, 1994; Bundtzen and others, 1994).
  • Age = Mid-Cretaceous or younger; vein cuts schist and marble metamorphosed during the mid-Cretaceous.
