Geologic setting

Geologic description

Johnson and Karl (1985) map the rocks in the area of this prospect as Cretaceous graywacke and argillite interbedded with sparse, lenticular beds of basalt. The rocks are cut by numerous high-angle, mainly northwest-striking faults; these include the extensions of the faults at the Chichagof Mine (SI093) which controls the mineralization there and whose trace is just northeast of this prospect. The only published information about this prospect is that it has been staked for lode gold (U.S. Bureau of Land Management, 2002).
