|Location and accuracy||This alluvial placer gold mine is on Banner Creek, a west tributary to Nome River opposite Sparkle Creek (NM302). The mouth of Banner Creek is 1.1 miles south of the Nome-Taylor road crossing of Nome River. Placer mine workings are present along at least a half mile of the central part of Banner Creek, between surface elevations of 150 and 250 feet. The map location is at the approximate midpoint of the placer workings, south of the center of section 5, T. 10 S., R. 33 W., Kateel River Meridian. It is locality 113 of Cobb (1972 [MF 463], 1978 [OFR 78-93]).|
Geologic descriptionGold was discovered on Banner Creek by 1900 (Brooks and others, 1901), and some placer mining took place by 1905 (Moffit, 1913). Placer tailings from more recent mechanical mining are along about 1,000 feet of the creek on a north-side bench below the mouth of Slate Creek. Bedrock in the area is graphitic schist, probably of early Paleozoic protolith age (Hummel, 1962 [MF 247]; Sainsbury, Hummel and Hudson, 1972 [OFR 72-326]; Till and Dumoulin, 1994). Bundtzen and others (1994) do not show bedrock along Banner Creek; their nearest mapped unit is the metaturbidite schist. Moffit (1913, p. 99) reported abundant marble (limestone) intercalated with schist in the canyon above the placer cut. Gold-bearing quartz veins also have been reported at the site (Moffit, 1913, p. 132).
