|Location and accuracy||This prospect is at an elevation of 2,800 feet on a conspicuous iron-stained knob at the north end of a canyon, about 0.7 mile east of the Richardson Highway. Access to the property is by a dirt road (not shown on the 1984 topographic map) on the east side of the highway approximately 1 mile south of Millers Roadhouse. The prospect is in the SE1/4SE1/4 section 18, T. 18 S., R. 11 E., Fairbanks Meridian. This prospect was first described by Hanson (1963, p. 67) and later by Rose (1965, p. 24).|
Geologic descriptionThis prospect consists of pyritized metadacite of the Slana Spur Formation of Pennsylvanian age (Nokleberg and others, 1991). Small amounts of lead were reported (Rose, 1965, p. 24) in the pyritized and iron-stained knob, locally called Gossan Hill, at the north end of a canyon. A sample of the pyritic metadacite assayed 2.2 percent copper and a half-ounce of silver per ton (W.T. Ellis, oral communication, 1998).
