Location: The Scotia prospect is at an elevation of about 250 feet on the northwest side of Anvil Creek, and it is 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, T10S, R34W, KRM. It is probably accurate to within 500 feet.

Geology: The Scotia prospect is probably within sheared wallrock near the Anvil fault. Cathcart (1922, p. 239) reported that an 8-inch quartz-calcite vein occurred 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).

Workings: A 10-foot tunnel was reported by Cathcart (1922, p. 239).

Age: Mid-Cretaceous or younger; vein cuts schist and marble metamorphosed during the mid-Cretaceous.

Commodities (Major) - Au (?)
Development Status: None
Deposit Model: Low-sulfide Au-quartz veins? (Cox and Singer, 1986; model 36a).
