Location and accuracy The Nation River prospect area covers about 10 square miles. The coordinates are for the center of the area, on the boundary between section 12, T. 6 N., R. 29 E., of the Fairbanks Meridian, and section 7, T. 6 N., R. 30 E., of the Fairbanks Meridian. The main mineralized area is in section 10, T. 6 N., R. 29 E., of the Fairbanks Meridian. The locations are accurate. These prospects are located within Doyon, Limited selected or conveyed land.

Geologic setting

Geologic description

The Nation River area of occurrences is defined by lead and zinc soil anomalies along with lesser copper values, that are associated with an east-west-trending fault. Iron staining is intense, and there are iron-rich seepages for half a mile in section 10, T. 6 N., R. 29 E. (Doyon, Limited, 1986). The prospect area is underlain by Permian limestone, Upper Devonian Nation River Formation, and Lower Cambrian Adams Argillite and Funnel Creek Limestone. All beds strike northeast and are repeatedly folded (Doyon, Limited, 1986).
The lead and zinc anomalies may reflect leaching of mudstone, siltstone, and sandstone country rocks or of a deeper, buried sulfide body (Doyon, Limited, 1986).
