Location: Cobb (1972, MF-413), loc. 3; NW1/4 sec. 23, T. 8 N., R. 5 W., of the Fairbanks Meridian. The Griffin prospect is between 1/4 and 1/2 mile northwest of Money Knob; it is about 1 mile south of Livengood, near the trail marked on the southeast corner of the Livengood (C-4) quadrangle. Accuracy is within 1,000 feet.
Geology: This prospect consists of a massive, sulfide-bearing, green-stained silica-carbonate-talc rock veined by quartz ; samples contain as much as 3.9 ppm Au, 1,000 ppm Ni, and 1,000 ppm Cr (Foster, 1968, p. 2, 10-11). A fire assay of one sample showed 5.6 ppm Au (Foster, 1968, p. 10-11). The nature of the contact between pyritiferous metasedimentary country rock and silica-carbonate-talc rock is not known (Foster, 1968, p. 2).
Workings: In 1955, the workings on the property included a shaft filled with water, an adit and several pits and trenches (Saunders, 1955).
Alteration: Deposit stained green by weathering of disseminated sulfides.

Commodities (Major) - Au; (Minor) - Cr, Ni
Development Status: None
Deposit Model: Quartz veins associated with silica-carbonate-talc rock.
