Comments
Comment (Reference): Primary Reference = Church and others, 1989 (MF468, Bulletin 1858)
Comment (Deposit): Model Name = Porphyry Cu, porphyry Cu-Mo, polymetallic vein (Cox and Singer; model 17, 21a, 22c).
Comment (Deposit): Model Number = 17, 21a, 22c
Comment (Deposit): Other Comments = Site is located in Katmai National Park.
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Miocene or younger
Comment (Geology): Geologic Description = Quartz stringers 1/2-inch or less thick are present in some felsic dikes and quartz diorite plugs of Miocene age, and in some of the sedimentary rocks cut by the intrusives. The stringers carry minor amounts of galena, gold, magnetite, molybdenite, pyrite, stibnite, and tetrahedrite. Bedrock consists of sedimentary units of the Shelikof formation of Jurassic age. Sericitic and propylitic alteration and silicification have been mapped over an area of several square miles and includes the mineralized rocks.? Silt samples collected within this area may exhibit anomalous amounts of molybdenum, whereas panned concentrates may show anomalous antimony, boron, copper, gold, and silver (Church and others, 1989, MF 1539 I, Bulletin 1858). Gold, chalcopyrite, pyrite scheelite, and tourmaline have been noted in the concentrates. Mineralized rock samples may be anomalous in copper, gold, molybdenum, silver, and zinc.
