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

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.
