The AG showing occurs near the eastern margin of the Coast Crystalline belt at the contact of Miocene volcanic rocks and metasedimentary rocks of probable Paleozoic age. The Paleozoic rocks are preserved as a roof pendant in plutonic rocks while the Miocene volcanics lie on both the metasedimentary and plutonic rocks. The volcanics may be comagmatic with some of the plutonic rocks of the area.

In the area of the showing are rhyolitic and dacitic volcanic rocks and feldspar biotite schist. Quartz monzonite crops out to the northeast. A number of narrow, widely-spaced massive sulphide veins occur as shear-fillings along a pyritically altered zone at the contact of the volcanics with metasedimentary rocks. The pyritic zone has been traced for nearly one kilometre along strike.

A 10-centimetre wide sulphide vein containing galena and chalcopyrite assayed 3.5 grams per tonne gold, 100 grams per tonne silver, 0.08 per cent copper, 0.27 per cent zinc and less than 0.1 per cent lead (Assessment Report 14096).
