Location: This prospect is at an elevation of 4,200 feet on the southwest valley wall of lower Canwell Glacier. It is in the NW1/4NE1/4 section 27, T. 18 S., R. 11 E., Fairbanks Meridian. Access to the property is by a 3-mile-long trail from the end of a dirt road (not shown on the 1984 topographic map) on the east side of the Richardson Highway at mile 213.5, approximately 1 mile south of Millers Roadhouse.
Geology: At the prospect, magnetite clots, pyrite, disseminated pyrrhotite, and traces of chalcopyrite and pentlandite occur within and at the margin of a fine- to medium-grained gabbronorite dike that cuts dunite (W.T. Ellis, oral communication, 1998). There is local copper staining in the dike. The rocks are part of the Canwell mafic-ultramafic intrusion of Late Triassic age. The complex is a 2.5-mile-long by 0.5-mile-wide sill that dips southwest and is intruded by a 6-mile-long Cretaceous quartz diorite to quartz monzonite stock (Barker, 1988). The Canwell complex consists of a dunite core that grades outward into wehrlite, feldspathic peridotite, and melagabbro (W.T. Ellis, oral communication, 1998). A total platinum group element (PGE) analysis of a high-grade sample from the prospect contained 0.86 percent copper, 1.2 percent nickel, 137 parts per billion (ppb) gold, 12,330 ppb platinum, 1,247 ppb palladium, 537 ppb osmium, 289 ppb iridium, 89 ppb rhodium, and 662 ppb ruthenium (W.T. Ellis, oral communication, 1998).
Workings: Exploration in the area of this prospect has been by American Copper and Nickel Company working with Fort Knox Gold Resources Inc. (W.T. Ellis, oral communication, 1998). Exploration from 1994 through 2001 included rock sampling, hand trenching, airborne and ground geophysical surveys, and completion of five diamond drill holes (W.T. Ellis, oral communication, 1998). The prospect was discovered in 1995. A total platinum group element (PGE) analysis of a high-grade sample from the prospect contained 0.86 percent copper, 1.2 percent nickel, 137 parts per billion (ppb) gold, 12,330 ppb platinum, 1,247 ppb palladium, 537 ppb osmium, 289 ppb iridium, 89 ppb rhodium, and 662 ppb ruthenium (W.T. Ellis, oral communication, 1998). The prospect is on active claims of Fort Knox Gold Resources.
