Location and accuracy | The occurrence is on a ridge about 5,200 feet in elevation between upper Indian Creek and the upper East Fork of Indian Creek. It is about 5.3 miles northeast of the center of Long Lake in the NW1/4NW1/4, section 33, T. 13 N., R. 6 E., Copper River Meridian. The occurrence is accurate to within 500 feet. |
Geologic descriptionThe 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. | |
