Geologic setting

Geologic description

The occurrence is in the Ahtell pluton about one-quarter of a mile east of its western contact (WGM Inc., 1980). It is about 3/4 mile north of the Tom Burns prospect (GU034) and it is mineralogically similar to it. Chalcopyrite and galena occur with quartz-carbonate gangue in a vein. No assay information is available.
