|Location and accuracy||This unnamed occurrence is in Section 22 at an elevation of about 2000 feet on the northwest flank of Banded Mountain (Berg and others, 1977, p. 133 and plate 1; Cobb, 1978, p. 87; Elliott and Koch, 1981, p. 8. loc. 16). The location is probably accurate to within about a quarter of a mile.|
Geologic descriptionThe country rock in the general area of this occurrence is graywacke of the Jurassic or older Mesozoic Hazelton Group (Berg and others, 1977, p. 15 and plate 1). A field investigation in 1973 by the U.S. Bureau of Mines (Berg and others, 1977, p. 133) reported that the deposit consists of a quartz pod that contains pyrrhotite and traces of chalcopyrite, in conspicuously iron-stained graywacke. The pod is about 2 feet thick and probably no more than 20 feet long; it pinches out at either end.

|Mineral deposit model||Polymetallic vein (Cox and Singer, 1986; model 22c).|
|Mineral deposit model number||22c|
|Alteration of deposit||Graywacke hostrock is conspicuously iron stained.|
|Workings or exploration||A channel sample taken by the U.S. Bureau of Mines in 1973 across the thickest part of the quartz pod containing the most abundant sulfides assayed 1200 ppm Cu and 1.5 ppm Ag. A grab sample of a smaller pod about 6 inches thick contained a similar amount of Ag, much less Cu, and 0.05 ppm Au.|
|Indication of production||None|
Twenty or more claims were staked in 1928 or 1929 on the northwest side of Banded Mountain, but it is not known whether they included this occurrence.The site is in Misty Fiords National Monument.
