Geologic setting

Geologic description

According to Jansons and others (1984), quartz veins can be found cutting massive metasandstone and slate of the Late Cretaceous Valdez Group. The veins are from 1 to 3 ft thick and contain minor pyrite and arsenopyrite. Only traces of gold and silver were found in the three grab samples.

Mineral deposit model Chugach-type low-sulfide Au-quartz veins (Bliss, 1992; model 36a.1?) or Epithermal Au vein?
Mineral deposit model number 36a.1?
Age of mineralization Late Cretaceous or younger; veins cut massive metasandstones and slates of the Late Cretaceous Valdez Group.

Production and reserves

Workings or exploration Only traces of gold and silver were found in the three grab samples, thus site has low mineral development potential (Jansons and others, 1984).
Indication of production None
