The No. 1 adit zone on the Olympic property follows a steeply dipping, southeast trending, brecciated shear zone at the faulted contact between Mississippian to Jurassic Bridge River Complex (Group) andesitic and silicic tuffs and crystalline carbonates and diorite of the Cretaceous to Tertiary Bendor pluton. Contact metamorphism has hornfelsed the sediments. Two parallel, narrow quartz-carbonate veins follow the shear and are heavily mineralized with large stibnite crystals and finely disseminated arsenopyrite and pyrrhotite. Samples assays 0.75 gram gold per tonne; a nearby trench ran 0.65 gram per tonne gold over 15 centimetres (Assessment Report 14344).
