Black River Occurrence, Iditarod District, Yukon-Koyukuk Borough, Alaska, USA

This page is currently not sponsored. Click here to sponsor this page.
Location: This placer occurrence is somewhat arbitrarily placed on the Black River at an elevation of about 350 feet, i.e., just within the the Iditarod C-1 quadrangle of the USGS. This is about 10 miles upstream from the mouth of the Black River in the McGrath quadrangle. The location is uncertain and based on old hearsay.
Geology: This placer occurrence is based on a report that George Fredericks, a trader at Georgetown on the Kuskokwim River, was given by an unidentified Athabascan Indian in 1914. The Indian said that placer gold had been found on the Black River about 10 miles from its mouth by Russian explorers in 1844 (Brown, 1983; Berry, 1973). However, there is no mention of such a discovery in the journals of the Russian explorer Lieutenant Zagoskin who visited this region about this time (Michael, 1967) and there is no other information about the deposit.

Commodities (Major) - Au
Development Status: None
Deposit Model: Placer Au deposit (Cox and Singer, 1986; model 39a).
