Location: The Canyon Creek prospect is at an elevation of about 4,700 feet on a spur west of upper Canyon Creek, a northern tributary to Ohio Creek. The map site is at the north-central boundary of sec. 28, T. 20 S., R. 12 W., of the Fairbanks Meridian. This is locality 19 of Cobb (1978: OFR 78-1062).
Geology: The country rocks in the area consist of several hundred meters of Triassic limestone and marble interbedded with basalt, metachert, and argillite. The strata are intruded by quartz diorite porphyry dikes of probable Late Cretaceous to Early Tertiary age and by Tertiary tourmaline-bearing granite. The Canyon Creek deposit in in the Upper triassic rocks, and consists of quartz-calcite veins containing arsenopyrite, chalcopyrite, pyrite and tetrahedrite. Rock chip samples contain up to 0.4 ppm gold and 500 ppm silver, along with consistently high Sn values. The Canyon Creek deposit is part of an area of sulfide deposits 2.5 miles long and 1 mile wide along and near Canyon Creek. The Canyon Creek prospect is in the northern part of this area. The Ready Cash prospect (HE057) is in southern part.
Workings: Surface exploration only. Rock chip samples contain up to 0.4 ppm gold and 500 ppm silver, along with consistently high Sn values.
Age: Late Cretaceous or younger, assuming that the deposit is related to the intrusive rocks.
Commodities (Major) - Ag, Au, Cu, Pb ; (Minor) - Sn
Development Status: None
Deposit Model: Polymetallic veins (Cox and Singer, 1986; model 22c)
