Cape Kubugakli Lode

The Cape Kubugakli Lode is a gold mine located in Alaska.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

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.
