Geological Summary |
Thick Upper Jurassic Nass Formation sediments overlie Middle Lower Jurassic thinly banded siltstones, volcanic conglomerates, volcanic breccias, volcanic sandstones, andesitic flows, and minor rhyodacite flows of the Unuk River Formation and the Betty Creek Formation (the former at the bottom of the sequence). Widespread alteration zones contain pervasive pyrite mineralization. Gold mineralization is indicated by stream sediment samples. The 1986 rock geochemical survey isolated a possible source for the anomalous stream samples.
