Geologic information

Identification information

Deposit ID 10003318
MRDS ID A106061
Record type Site
Current site name Mt. Dutton

Geographic coordinates

Geographic coordinates: -162.2591, 55.16587 (WGS84)
Relative position Approximate location is about 4 km south of the summit of Mt. Dutton. Probably same location as anomaly no. 57 of Christie (1974), described as 2 mi (3.2 km) due north of King Cove landing strip. Also, no. 10 of MacKevett and Holloway (1977, p. 9).

Comments on the geologic information

  • Geologic Description = Two color anomalies 200 by 400 ft and 3,000 by 1,200 ft (60 by 120 and 900 by 360 m) in hornfelsed volcanic rocks cut by rare diorite dikes (Christie,1974). Pyrite content (0 to 8 percent) is highest in fractured rocks, although most pyrite is disseminated rather than fracture-controlled. Diorite dikes are only weakly altered and are not mineralized. Butherus and others (1979) reported that the color anomalies south and east of Mt. Dutton consist of altered, pyritic andesite containing quartz and calcite veins.
  • Age = Miocene or younger

Economic information about the deposit and operations

Development status Occurrence
Commodity type Metallic

Comments on exploration

  • Status = Inactive

Mining district

District name Alaska Peninsula

Comments on the workings information

  • Workings / Exploration = Christie (1974) reported brief reconnaissance geologic mapping and collected silt samples, none of which showed any anomalies in copper, molybdenum, zinc, silver, or gold. Butherusand others (1979) reported rock and pan concentrate samples slightly anomalous in copper (130 ppm), lead (300 ppm), zinc (600 ppm), and silver (3.2 ppm).

General comments

Subject category Comment text
Deposit Model Name = Porphyry copper, polymetallic vein, epithermal gold vein
Deposit Model Number = 17, 22c, 25
Deposit Other Comments = Reported quartz veining (Butherus and others, 1979) lsuggests possibility of epithermal gold vein or polymetallic vein type mineral deposits.
