Peternie

The Peternie is a zinc, molybdenum, and copper 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 (Workings): Workings / Exploration = Extensive drilling and prospecting took place on the site in the 1970's, as well as airborne magnetometer studies. The property was soil sampled in the early 1980's, and is now within Doyon Ltd. selected lands.

Comment (Geology): Geologic Description = The Peternie prospect consists of disseminated sulfide minerals in altered and leached quartz monzonite and latite porphyry (Singer and others, 1976). Potassium feldspar in a vein cutting the intrusive has a 40Ar/39Ar age of 102.8 +/- 0.5 Ma (Newberry and others, 1996). In 1974, some drilling and sampling took place. Sampling results show that copper minerals and molybdenite are probably present. Elevated molybdenum and zinc values were also reported in rock grab samples. Seven drill pads are visible from the air, and several thousand feet of drill core are stockpiled on site. Examination of random core boxes in 1984 by Doyon Ltd. showed pervasive potassic, propylitic, and phyllic alteration in the majority of samples examined. Systematic rock and soil sampling have also been conducted on the property (Doyon Ltd., 1998).

Comment (Deposit): Other Comments = See North Peternie prospect (TC020) and VW (TC030) prospect. This prospect is located on Doyon Ltd. selected land. For more information, contact Doyon Ltd.? Peternie is sometimes called Paternie, but the correct name is Peternie (Doyon Ltd., 1998).

Comment (Reference): Primary Reference = Doyon Ltd., 1998

Comment (Deposit): Model Name = Porphyry Cu-Mo deposit (Cox and Singer, 1986; model 21a)

Comment (Geology): Age = Potassium feldspar in a vein cutting the intrusive has a 40Ar/39Ar age of 102.8 +/ - 0.5 Ma (Newberry and others, 1996).
