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).
Location: The Peternie prospect is located within sections 7 and 18, T. 21 N., R. 14 E., of the Copper River Meridian and sections 12 and 13, T. 21 N., R. 13 E., of the Copper River Meridian. It encompasses about 4 square miles and is 9 miles west of the Dennison Fork of the Fortymile River. It is location 2 of Singer and others (1976). The coordinates given are for the approximate center of the prospect. The location is accurate to within 1/2 mile.
Geology: 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).
Workings: 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.
Age: Potassium feldspar in a vein cutting the intrusive has a 40Ar/39Ar age of 102.8 +/ - 0.5 Ma (Newberry and others, 1996).
Alteration: Pervasive hydrothermal alteration, evidenced by potassic, propylitic, and phyllic alteration in core (Doyon Ltd., 1997).

Commodities (Major) - Cu, Mo, Zn
