The Lisadele area is underlain by two units of the Early Eocene Sloko Group consisting of coarse volcaniclastic and pyroclastic volcanic rocks; and conglomerate and coarse clastic sedimentary rocks. Contact with a Jurassic Laberge Group unit consisting of mudstone, siltstone, shale and fine clastic sedimentary rocks occurs in the showing area.

The Lisadele occurrence is at the contact between Sloko and Laberge Group strata. Parallel tetrahedrite-chalcopyrite-sphalerite (plus/minus very fine grained stibnite(?) and galena)veins, 1 to 5 centimetres thick (rarely to 40 cm), extend for at least 125 metres along strike. These veins are focused in a zone 5 metres wide, but occur widely spaced over a width of about 40 metres perpendicular to strike. The best analytical results are 2.2 per cent copper, 1.8 per cent lead, 0.8 per cent zinc and 161 grams per tonne silver (Fieldwork 1994, page 339).
