The Chitsia Creek is a gold mine located in Alaska.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.
Mine Info
Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Geology): Age = Quaternary
Comment (Production): Production Notes = There are no indications of production.
Comment (Reference): Primary Reference = Bond, 1985
Comment (Workings): Workings / Exploration = 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).
Comment (Deposit): Model Name = Placer Au (Cox and Singer, 1986; model 39a).
Comment (Deposit): Other Comments = the Chitsia Creek prospect is located on land selected by or conveyed to Doyon, Limited. For more information, contact Doyon, Limited.
Comment (Exploration): Status = Inactive
Comment (Geology): Geologic Description = 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.
