The area is underlain by argillite, greywacke, and conglomerate of the Jurassic to Cretaceous Bowser Lake Group. Narrow quartz veins lie conformably below a 35 to 75 metre wide conglomerate bed which strikes northeast and dips 50 to 75 degrees southeast.
A 6 metre long, 0.5 metre wide quartz vein occurs in a sheared zone in the conglomerate. It strikes 030 degrees and dips 65 degrees west. A 1 metre sample assayed 12 grams per tonne gold (Annual Report 1930).
