|Location and accuracy||5 km northwest of False Pass community on Unimak Island. Anomaly no. 50 of Christie (1974) and no. 3, of MacKevett and Holloway (1977, p. 11).|
Geologic descriptionChristie (1974) briefly examined a northeast-trending elongate color anomaly 4,000 ft (1.2 km) by 1,500 ft (450 m) in size, developed in andesitic volcanic flows and pyroclastic rocks. Diorite was found in creek float but no outcrops were seen. Pyrite is disseminated both in the diorite and the volcanic rocks and its concentration ranges between 2 and 5 percent.

|Mineral deposit model||Epithermal gold vein|
|Mineral deposit model number||25|
|Age of mineralization||Miocene or younger|
|Alteration of deposit||Alteration is not described other than to mention of clay and possible local silicification.|
|Workings or exploration||Brief reconnaissance geologic mapping and collection of a few silt samples. One sample had 0.01 ppm gold. Occurrence apparently has not been adequately examined for epithermal gold vein potential.|
|Indication of production||None|
Additional commentsQuartz veining is not mentioned by Christie (1974), but this does not mean that it is absent, inasmuch as his focus was mainly on porphyry mineralization.
