This massive sulfide prospect is in the Ambler schist belt. Nana Develpment Corporation information based on a 1984 unpublished Bear Creek Exploration report.
Location: Located north of VABM Ruby on ridge between Ambler and Shungnak Rivers in sec. 17, T. 22 N., R. 10 E., Kateel River Meridian. Shown as locality 39 in Mayfield and Grybeck (1978) and accurate to within 2000 ft. (600 m).
Geology: Pyrite, chalcopyrite, bornite, galena and sphalerite form lenses, stringers, disseminations, and locally massive pods in metamorphosed Devonian-Mississippian volcanic, volcaniclastic, and sedimentary rocks. Sulfide lenses are complexly folded and faulted. Country rocks are interbedded porphyroblastic quartz-muscovite-calcite schist, graphitic schist, greenstone, (some have pillow structure, and some occur as plugs and sills throughout the section), and weakly metamorphosed semischistose graywacke (Nana Development Corp., written comm., 1997). Deposit is reported similar to Artic deposit (AR025).
Workings: Surface geologic mapping, electromagnetic studies, geochemical sampling, trenching, and eight drill holes.
Age: Devonian

Commodities (Major) - Cu, Pb, Zn
Development Status: No
Deposit Model: Kuroko
