Location: Chitsia Creek drains northwest into the Kantishna River. The creek is roughly 21 miles long and has several tributaries. The Alaska Division of Mining Kardex file system reports placer claims on Chitsia Creek north of Chitsia Mountain. The approximate center of mining activity on Chitsia Creek is in NE1/4NW1/4 section 22, T. 10 S., R. 15 W., of the Fairbanks Meridian, at an elevation of about 700 feet. There are references to additional placer mining along Chitsia Creek, but it is unclear where. The Chitsia Creek prospect is located on land selected by or conveyed to Doyon, Limited.
Geology: Along Chitsia Creek, north of Chitsia Mountain, the geologic units are Miocene to Pliocene Nenana gravels overlain by unconsolidated Quaternary silt and colluvium. The Nenana gravels consist of weakly consolidated pebble conglomerate and thin-bedded sandstone and claystone (Chapman and Yeend, 1981). Regionally, the area contains a system of northeast-trending strike-slip and related conjugate faults associated with Cretaceous to Tertiary plutonic rocks and coeval or younger volcanic rocks (Clautice and others, 1993). Float collected from Chitsia Creek, north of Chitsia Mountain, consisted of quartz-muscovite schist, white bull quartz with iron-oxide, and biotite-feldspar-quartz gneiss (Bond, 1985). A pan concentrate from Chitsia Creek assayed by the acid digestion method contained 340 ppb Au, 60 ppm Cu, 10 ppm Pb, 170 ppm Zn, 3 ppm Mo, 20 ppm As, and 10 ppm W (Bond, 1985). Placer gold was discovered in the stream gravels of Chitsia Creek by George Wickersham during the 1903 expedition to Mt. McKinley (Bundtzen and others, 1976). There are no indications of production.
Workings: Placer gold was first discovered in the stream gravels of Chitsia Creek by George Wickersham during the 1903 expedition to Mt. McKinley (Bundtzen and others, 1976). The area was later mapped by Chapman and Yeend (1981).
