Location: This prospect is 1.6 miles N 36 E of the Foster prospect (BN098). The Foster prospect is in the headwaters of a north tributary of Omilak Creek at an elevation of approximately 1,250 feet. Omilak Creek flows westward from headwaters in the northern Darby Mountains to the Fish River in McCarthy's Marsh.
Geology: Oxidized galena in soil and gossan material occurs with ubiquitous fragments of black phyllite in a prospect trench (Briskey, 1983). This is within a northwest-trending zone of iron-oxide staining that is traceable at the surface for 800 feet. Assays of 24 samples of material in the prospect trench contained 20 ppm to 6.8 % Pb, 25 ppm to 3.4 % Zn, 10 to 2,200 ppm Cu, and 0.2 to 1,850 ppm Ag. The average of these samples was 0.84 % Pb, 0.37 % Zn, 221 ppm Cu, and 320 ppm Ag. This mineralization is localized near the axis and along the west limb of a large northwest plunging syncline in high grade metasedimentary rocks (Till and others, 1986).
Workings: A small surface prospect trench is present here.
Age: Cretaceous ?; Epigenetic mineralization in metamorphic rocks of Seward Peninsula is primarily of Cretaceous age.
Alteration: Oxidation of sulfide minerals.
Commodities (Major) - Ag, Pb, Zn
Development Status: No
Deposit Model: Polymetallic vein or replacement in marble (Cox and Singer, 1986; model 19a or
