Location: Alaska Department of Natural Resources unpublished claim records show the location of this prospect in Upper Sucker Creek, Sections 5,7,18 and 19, T. 17 N., R. 9 W. and Sections 11, 12, and 13, T. 17 N., R. 10 W., approximately four miles north of Little Mt. Susitna. Location given is in the the northern part of the claim block.
Geology: A variety of lithologies, including marble, clastic sedimentary rocks, and intrusive and volcanic rocks, have been mapped on the property. Copper-gold-magnetite occurs as skarns developed in the carbonate-rich rocks (K. Adler, Rev. Michael Hornick, personal communication, 1998).
Workings: Work on the property included mapping; airborne magnetic, ground magnetic and VLF geophysical surveys; rock and stream silt geochemical surveys. Thick cover precludes meaningful soil sampling surveys.
Commodities (Major) - Au, Cu; (Minor) - Fe
Development Status: None
Deposit Model: Cu skarn; unknown if porphyry-related (Cox and Singer, 1986; models 18a or 18b)
