|Location and accuracy||This placer mine location (locality 76 of Cobb and Matson, 1972), is on Mineral Creek near the mouth of East Fork. It is approximately located, perhaps to within 1 mile.|
Geologic descriptionLow-grade placer gold deposits have been intermittently mined at various locations on Mineral Creek from before 1898 to at least 1914 (Cobb, 1972, OFR 79-1241). Bedrock in the area is greenschist-facies metaflysch of the Late Cretaceous Valdez Group (Winkler and others, 1981 [OFR 80-892-A]). Gold-bearing quartz veins that may have contributed to Mineral Creek placers are widespread in the Valdez Group (Cobb and Matson, 1972).
