Geologic setting

Geologic description

The Skookum Chief prospect was discovered prior to 1936 when native gold was found in a thin layer of debris on bedrock. There are 5 open cuts on the prospect (Redman and others, 1989). The country rocks at this prospect consist of black phyllite and a 150-foot thick greenstone unit. The deposit consists of quartz veins and stringers in the greenstone. The quartz is sheared. Pyrite and native gold occur in the quartz and along fractures in the greenstone (Wells and others, 1986).
The rocks in the general area are Upper Jurassic or Cretaceous marine argillite and graywacke, interbedded with andesite or basalt (Brew and Ford, 1985). The bedded rocks are regionally metamorphosed to prehnite-pumpellyite or greenschist grade, and cut by diorite or gabbro dikes and sills.
