Geologic setting

Geologic description

Christie (1974) reports a 3,000 by 1,000+ ft (900 by 300+ m), elongate to the northeast, color anomaly in volcanic rocks, mainly agglomerate and flows(?). Pyrite is disseminated and to a minor degree localized in fractures in the volcanic rocks. Maximum total sulfide content is 2 to 3 percent. No intrusive rocks were found.
Geologic map unit (-162.70200689218, 55.0574258314295)
Mineral deposit model Epithermal gold vein, polymetallic vein
Mineral deposit model number 22c, 25
Age of mineralization Pliocene or younger
Alteration of deposit Possibly propylitic, based on presence of chlorite.

Production and reserves

Workings or exploration Brief reconnaissance geologic mapping and collection of a few silt samples reported by Christie (1974). Silver to 1.3 ppm, otherwise background levels for copper, molybdenum, zinc, and gold.
Indication of production None
