North Peternie

The North Peternie is a lead 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 (Geology): Age = 40Ar/39Ar dates of potassium feldspar in a vein cutting the intrusive at the Peternie prospect (TC022) nearby yield an age of 102 Ma for the mineralization (Newberry and others, 1996).

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

Comment (Workings): Workings / Exploration = Ridgeline soil has been sampled at the prospect.

Comment (Exploration): Status = Active

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

Comment (Deposit): Other Comments = This property is located on Doyon Ltd. selected lands. For more information, contact Doyon Ltd.

Comment (Geology): Geologic Description = The North Peternie prospect is believed to be part of the same system as Peternie prospect (TC022) and VW prospect (TC030). They are all thought to be porphyry Mo deposits within quartz monzonite and latite porphyry intrusive rocks. The geology at the prospect consists of pyritic, granite intrusives (Foster, 1970). Potassium feldspar in a vein cutting the intrusion at Peternie has a 40Ar/39Ar age of 102.8 + / - 0.5 Ma (Newberry and others, 1996). The North Peternie prospect lies within the Y1 subterrane of the Yukon-Tanana terrane (Foster and others, 1994). Ridgeline soil samples at North Peternie show anomalous values of molybdenum and silver (Doyon Ltd., 1998).
