The rocks in the area are derived from Devonian felsic to intermediate volcanic rocks, mainly andesite, dacite, and quartz keratophyre flows and tuffs, and from Devonian or older shale, marl, and marble (Nokleberg and others, 1992 [MF]; 2002 [\Open-File]; Bittenbender and others, 2007). The rocks were intensely deformed into chlorite schist, limestone, and greenstone that were first metamorphosed to lower amphibolite facies in the Early Cretaceous and then retrograded to lower greenschist facies in the mid-Cretaceous.

Resource Associated of Alaska was active in the area in 1970s but they deeded their claims to the Cook Inlet Region Incorporated in 1980 (Bittenbender and others, 2007). The prospect was examined and sampled by the U.S. Geological Survey in about 1990 (Nokleberg and others, 1991), by the American Copper and Nickel Company in 1993, and by the Bureau of Land Management in the early 2000s. There are no workings on the prospect.

Samples taken during a U.S. Geological Survey reconnaissance in the 1980s consisted of disseminated to semi-massive pyrite, chalcopyrite, galena, sphalerite, and pyrrhotite in chlorite-epidote-carbonate schist (Nokleberg and others, 1991). A grab sample of chalcopyrite-bearing schist contained 0.92 percent copper, 0.22 percent zinc, 0.06 percent lead, and 10 parts per million (ppm) silver.
