Location: This prospect is at an elevation of about 5,000 feet, on the northeast wall of the valley of upper Partin Creek. The map site is in the SW1/4 of sec. 25, T. 21 S., R. 13 W., of the Fairbanks Meridian. The location is known to within 0.25 mile. This is location 23 of Cobb (1978: OFR 78-1062).
Geology: The country rocks in the area of this prospect are Upper Triassic limestone and basalt cut by Upper Cretaceous or Lower Tertiary biotite-quartz diorite porphyry. The deposit consists of auriferous skarn containing pyrite, pyrrhotite, chalcopyrite, arsenopyrite, and stibnite. Gold grades are higher near the intrusive contact. Samples contain up to 0.2 ounces of gold per ton and 0.7 percent copper (Hawley and Clark, 1974).
Workings: There has been limited exploration consisting of shallow trenches and rock chip samples.
Age: Probably Late Cretaceous or younger.
Alteration: Formation of skarn at intrusive contacts.
Commodities (Major) - Ag, Au, Cu; (Minor) - Sb
Development Status: None
Deposit Model: Cu skarn (Cox and Singer, 1986; model 18b)
