|Location and accuracy||A vein containing gray copper was reported by Collier and others (1908) on a steep bluff above Norton Sound about one-half mile west of the mouth of Quartz Creek (NM122). The vein is only approximately located, probably within a third of a mile. This occurrence was included as part of locality 63 by Cobb (1972 [MF 463], 1978 [OFR 78-93]).|
Geologic descriptionA quartz-sulfide (sulfosalt) vein several feet thick was reported by Collier and others (1908, p. 215) to be exposed on the bluffs above Norton Sound a short distance west of Quartz Creek. The vein was concordant to schistosity at a contact between chloritic and graphitic schist layers. Assays reported only trace amounts of gold and silver. The sulfide or sulfosalt mineral is described only as gray copper, most probably tennantite. The vein was lenticular and reportedly 'thinned rapidly' (Collier and others, 1908).
|Geologic map unit||(-166.018810712465, 64.5658229374219)|
|Mineral deposit model||Quartz-sulfide (sulfosalt) vein in metamorphic rocks.|
|Age of mineralization||Because the vein is concordant to metamorphic foliation, it could be older than mid-Cretaceous, but a younger age is also possible.|
|Workings or exploration||Prospecting activity occurred in the area shortly after the discovery of gold at Nome in 1898. The vein was discovered about 1903 or earlier.|
|Indication of production||None|
