Location: This occurrence is on the ridge crest at the head of Arctic Creek, 3.8 miles southeast of Taylor on the Nome-Taylor road. Sainsbury and others (1969) report mineralization in marble outcrops just to the east of the road here. This is locality 3 of Cobb (1972; MF 417; 1975; OFR 75-429).
Geology: Marble interlayered in pelitic schist forms outcrops just east of the Nome-Taylor road. Sainsbury and others (1969) describe replacements of marble by banded, fine-grained silica containing pyrite and traces of chalcopyrite. Although mapped as klippe by Sainsbury and others (1969), the marble is interlayered with schist and part of a low grade, Lower Paleozoic metasedimentary assemblage (Till and others, 1986).
Workings: Some shallow propecting pits may be present.
Age: Unknown but possibly Cretaceous; the major episode of epigenetic mineralization on Seward Peninsula accompanied higher temperature metamophism and mid- to Late Cretaceous granitic plutonism in the region.
Alteration: Silica replacements of marble (?).

Commodities (Major) - Cu
Development Status: No
Deposit Model: Siliceous zones in marble with pyrite and traces of chalcopyrite
