Location: Banner Creek is an east tributary to the Anikovik River; their confluence is about 2.3 miles upstream from the mouth of the Anikovik River at York on the Bering Sea. The USBM completed three churn-drill holes on a line across this creek about 0.75 miles upstream from the mouth on Anikovik River. The churn-drill holes are just upstream of an unnamed south tributary to Banner Creek. This is locality 39 of Cobb and Sainsbury (1972). Cobb (1975) summarized relevant references under the name 'Banner Cr.'.
Geology: Banner Creek flows west from headwaters in Ordovician limestones of the York Mountains (Sainsbury, 1972) but most of its drainage is across a thin bedded metapelitic and metasandstone sequence of unknown but probable Paleozoic age. The USBM completed three churn-drill holes on a line across Banner Creek about 0.75 miles upstream from the mouth on Anikovik River; this location is just upstream of an unnamed south tributary to Banner Creek (Mulligan, 1959). The churn-drill holes encountered five feet of gravel on bedrock. Heavy mineral concentrates contained a trace of tin and included pyrite, limonite psuedomorphs after pyrite, ilmenite, tourmaline, zircon, augite, hematite, hypersthene, and cassiterite. Although first reports from this creek indicated the presence of some gold (Cobb, 1975), the USBM drilling did not encounter it. Mulligan (1959, p. 17) noted the presence of a felsic dike (with some sulfide minerals) in bedrock near the churn-drill locations.
Workings: Three USBM churn-drill holes have been completed here (Mulligan, 1959).
