Location and accuracy Placer mining has taken place at various locations on Mineral Creek upstream from the town of Valdez for at least 4.5 miles (Winkler and others, 1981 [OFR 80-892-B], locality 63). The coordinate location used here are on the north side of Valdez at the placer locality shown by Cobb and Matson (1972, locality 77).

Geologic setting

Geologic description

Low-grade placer gold deposits have been mined intermittently on Mineral Creek at various locations upstream from Valdez 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 contribute to this placer are widespread through the Valdez Group in the southern Valdez quadrangle (Cobb and Matson, 1972).
