Location: Champion Creek is a small, north tributary to Mina Creek. This prospect is on the ridge crest at an elevation of 840 feet, overlooking the mouth of Mina Creek on Kugruk River. The mouth of Mina Creek, an east tributary to Kugruk River, is 6.5 miles north of the Independence Mine (BN076). This is locality 30 of Gamble (1988).
Geology: Samples collected in the prospect trenches described as partly brecciated, iron-stained, dolomitic marble (Gamble, 1988), contain up to 1.4 % Zn, 7,000 ppm Pb, 10 ppm Ag, 1,000 ppm Cu, 300 ppm Cd, 360 ppm As, and 600 ppm Sb. Bedrock is extensively covered by tundra but what is exposed in the area is part of a lower Paleozoic metasedimentary assemblage (Till and others, 1986). Bedrock to the east of Independence Creek and northwest of Kiwalik Mountain may contain felsic metavolcanic rocks. Felsic metavolcanic rocks are associated with massive sulfide prospects, one 9,000 feet to the southeast of this locality (BN119) and one at Big Bar (BN083), southeast of Kiwalik Mountain.
Workings: Some prospect (dozer ?) trenches are reported (Gamble, 1988).
Age: Unknown; if epigenetic, probably Cretaceous. If stratiform, probably Paleozoic.
Alteration: Oxidized; limonitic staining of marble.
Commodities (Major) - Ag, Cu, Pb, Zn; (Minor) - Cd
Development Status: None
Deposit Model: Polymetallic sulfide mineralization in marble
