Geologic setting

Geologic description

Bedrock in the area of the Alameda Creek placer deposit consists of Jurassic or Cretaceous sandstone, siltstone, and shale that are cut by thrust and high-angle faults (Chapman and others, 1982; Reifenstuhl and others, 1998).
The topographic map of the Tanana A-1 quadrangle (1952, with minor revisions in 1963), shows several ditches contouring around the slopes of Alameda Creek. This development work is not mentioned in published reports. In 1989, Ed Salter worked Alameda Creek approximately 1 mile east of McCaskey Bar (TN131) (Bundtzen and others, 1990). According to Bottge (1986), gold had been recovered from Alameda Creek by 1985.

Production and reserves

Workings or exploration The topographic map of the Tanana A-1 quadrangle (1952, with minor revisions in 1963), shows several ditches contouring around the slopes of Alameda Creek. Two ditches feed into Alameda Creek, presumably to help offset the scarcity of water in the summer. This development work is not mentioned in published reports. In 1989, Ed Salter worked Alameda Creek approximately 1 mile east of McCaskey Bar (TN131) (Bundtzen and others, 1990). According to Bottge (1986), gold had been recovered from Alameda Creek by 1985.
Indication of production Yes; small
Production notes In 1989, Ed Salter worked Alameda Creek approximately 1 mile east of McCaskey Bar (TN131) (Bundtzen and others, 1990). According to Bottge (1986), gold had been recovered from Alameda Creek by 1985, but the amount is undisclosed.
