Location: This prospect is at an elevation of about 450 feet on northeast Kruzof Island, about 3.5 miles south of Sukoi Point. The prospect is 0.2 mile southeast of the center of sec. 15, T. 53 S., R. 61 E. It is location P-106 of Bittenbender and others (1999) and MAS no. 0021140151 (U.S. Bureau of Land Management, 2002). The location is accurate within about a mile.
Geology: Loney and others (1975) map the rocks in the area of this prospect as Jurassic and Cretaceous graywacke. The rocks near the prospect are cut by at least one high-angle, north-striking fault, and the Neva Strait Fault, a regional-scale, steeply-dipping, northwest-striking fault is about 4 miles northeast of the prospect. Bittenbender and others (1999) describe the prospect as a gold-lead-zinc-bearing, quartz vein along the contact between greenstone and argillite. Samples from the Little Blonde claim assayed up to 0.42 ounce of gold per ton across 0.6 foot of quartz. Selected mineralized float on the High Grade claim assayed up to 3 ounces of gold per ton, but most of the samples contained no gold. The ore minerals were not identified.
Workings: Only surface sampling.

Commodities (Major) - Au, Pb, Zn
Development Status: Undetermined.
Deposit Model: Low-sulfide gold-quartz vein (Cox and Singer, 1986; model 36a).
