At the Humbird-Camp showing, west of Samuel Glacier, an oxidized zone of vein and replacement mineralization occurs near a contact between limestone and talc-sericite schist in deformed Ordovician- Devonian metasediments. Sulphides include chalcopyrite, sphalerite, galena, and possibly freibergite. The zone was reported to be 3 metres wide and extend 50 metres along a north strike. A high-grade shipment of less than 4.5 tonnes was made from this occurrence. A grab sample from the vicinity of the high-grade vein assayed 21.26 grams per tonne silver, 0.25 per cent copper, 0.17 per cent zinc, and 0.02 per cent lead.
