Comments on the geologic information

  • Geologic Description = A pale yellow-brown to medium red-brown color anomaly 3,000 ft (900 m) in diameter in pyroclastic rocks and volcanic flows (andesite to dacite) of Unalaska Formation (see Drewes and others, 1961). The rocks contain disseminated and locally mineralized fracture concentrated sulfides and are cut by post-mineralization augite andesite dikes. Christie (1974) indicated that there is no evidence that this sulfide system is related to an intrusive body because exposure is sufficiently good to rule out the existence of one. No copper was observed (the goal of Christie's examination efforts).
  • Age = Cenozoic

Economic information about the deposit and operations

Development status Occurrence
Commodity type Metallic

Comments on exploration

  • Status = Inactive

Mining district

District name Aleutians

Comments on the workings information

  • Workings / Exploration = Limited reconnaissance mapping and 3 soil(?) samples. Samples contained up to 1.8 ppm silver, one contained 0.01 ppm gold and 9 ppm molybdenum.

General comments

Subject category Comment text
Deposit Other Comments = Localization of sulfides and silicification, the gold and silver anomalies, and the local geologic context suggests epithermal mineralization might warrant consideration.
