The PJ occurrence area is underlain by strongly jointed porphyritic basalts of the Upper Triassic Karmutsen Formation, Vancouver Group. The basalts host a fracture-related, narrow quartz vein striking 335 degrees and dipping 75 degrees east. The vein ranges from 0.1 to 0.5 metres in width and is exposed over a strike length of 45 metres by several pits. It is crudely banded with minor carbonate and passes laterally to a rusty shear. Minor pyrite is present. The core of the vein, 7 centimetres wide, contains disseminated sphalerite and galena which occasionally forms thin lenses.

A grab sample from the core of the vein assayed 31.94 grams per tonne gold, 77.81 grams per tonne silver, 3.08 per cent lead and 3.01 per cent zinc (Assessment Report 10573).
