Location and accuracy Winona Creek is an east tributary to Boulder Creek, a north tributary to the Noxapaga River. The mouth of Winona Creek is 1.4 miles downstream from the juncture of Boulder Creek with Turner Creek, a west tributary. This location is approximate and only known to be on Winona Creek. It is locality 48 of Cobb (1972; MF 417; 1975; OFR 75-429).

Geologic setting

Geologic description

Gold was discovered soon after the turn of the century on tributaries to the Noxapaga River including Winona Creek (Collier and others, 1908) and mining took place here after WW II (Hopkins, 1963). Frozen, stratified peat and silt (muck), 20 to 30 feet-thick, commonly overlies a few feet of auriferous gravel on schist bedrock (Hopkins, 1963, Figure 8, p. 94). Muck locally contains bones of extinct Pleistocene mammals. Although tundra cover of bedrock is extensive in the area (Till and others, 1986), Hopkins (1963) indicates that quartz-calcite veins are common in schist bedrock of the gold- producing tributaries to the Noxapaga River.

Mineral deposit model Placer Au-PGE (Cox and Singer, 1986; model 39a).
Mineral deposit model number 39a
Age of mineralization Quaternary; an early radiocarbon age on shallow parts of the frozen and stratified peat and silt of the nearby Black Gulch (BN018) was 8,800 +/- 200 years (Hopkins, 1963, Figure 8).
