The Goldfish showing area is underlain by rock of the Middle Jurassic Naglico Formation, Hazelton Group.
A zone of volcanic breccias in andesite porphyry has been cut by late stage open space quartz veining. Propylitic alteration is associated with this veining along with jasper hematite replacement. Minor amount of copper mineralization is observed to be associated with quartz veining and alteration. The quartz veins trend north-west and north-east. The veins are vuggy having quartz crystals and calcite associated. Pyrite, specular hematite and rare copper minerals can occur within the veins.
In 2010, Kootenay Gold collected 21 rock samples at the Goldfish showing. The showing was not previously documented.
