The area of the Basement-June 21 showing is underlain by steep east-dipping Devonian to Upper Triassic metasediments and metavol- canics of the Icefield Ranges assemblage. Pyrrhotite veins and stringers with disseminated pyrite and accessory chalcopyrite occur in a marble bed within a chlorite schist unit which has been intruded by mafic dykes. A grab sample with chalcopyrite ran 7.3 grams per tonne gold, 0.076 per cent copper, and 1.6 grams per tonne silver.
