The claim is underlain by Lower Jurassic Hazelton Group vol- canics comprised of red andesitic flows and tuffs with breccia, green tuff and rhyodacite flows. The showing is within a shear zone in the volcanics. The zone contains bands of quartz veins with minor occurrences of arsenopyrite, sphalerite and pyrite.

The upper showing consists of a 8 to 15 centimetre quartz vein which strikes 080 degrees and dips 42 degrees south, with abundant pyrite and lesser arsenopyrite, sphalerite, galena, and minor chalcopyrite. The vein is hosted by hornfelsed, fine-grained tuff. Above the upper adit portal a 10 centimetre wide quartz- carbonate vein with arsenopyrite, pyrite, and minor galena strikes 100 degrees and dip 10 degrees south. The continuation of the upper adit vein appears to be a 3 to 5 centimetre shear with gouge striking 100 degrees and dipping 60 degrees south.

In 1986 samples from this adit assayed 3.6 to 6.2 grams per tonne gold, 8.2 to 32.6 grams per tonne silver with up to 8.66 per cent zinc and 0.87 per cent lead (Assessment Report 15140).
