|Location and accuracy||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.|
Geologic descriptionThe 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).
