Location: The Nenana prospect is at an elevation of about 4,800 feet, 1.75 miles west southwest of VABM 5756 (Fork). The map site is in the SW1/4 of sec. 30, T. 16 S., R. 1 E., of the Fairbanks Meridian. The location is accurate to within 1500 feet. This is location A-76 of Balen (1990: OFR 34-90).
Geology: The area of the Nenana prospect is underlain by Upper Triassic, thin-bedded, commonly cross-bedded, carbonaceous shale, argillite, sandstone, and siltstone. The strata are cut by numerous dikes, sills, and plugs of altered diabase and gabbro, and by Upper Cretaceous?-Lower Tertiary granites (Wilson and others, 1998). The prospect consists of pyrite?, chalcopyrite, and sphalerite disseminated in the sedimentary rocks.
Workings: Exploration consisted of rock-chip and soil sampling (unpublished report for the New Alaska Syndicate, 1977).
Age: The sulfide minerals probably are syngenetic with their Upper Triassic host rocks.
Commodities (Major) - Cu, Zn; (Minor) - Ag
Development Status: None
Deposit Model: Besshi massive sulfide (Cox and Singer, 1986; model 24b)
