|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 descriptionLow-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).
