Geologic setting

Geologic description

The mineralization consists of a reddish-brown iron-stained zone more that 30 feet wide. The host rock in this area is mapped as Valdez Group of Late Cretaceous age (Nelson and others, 1984). A single grab sample contained 3,000 ppm manganese, 70 ppm chromium, and 60 ppm zinc (Tysdal, 1978 [MF-880-A]).
