The claim is underlain by Upper Triassic volcanic and sedimentary rocks of the Takla Group. Bedrock is generally obscured by glacial overburden but local outcrops consist of dark green to dark grey andesites and basalts. No mineralization is known to occur on the property. The electromagnetic anomaly in the southwest part of the Boo 1 claims should be further explored to the north of Ahbau Creek.
