The Southair property is located east of Callaghan Creek and north of Brandywine Falls near the village of Whistler on Highway 99. A north trending, subvertically dipping succession of metavolcanics and metasediments of the Lower Cretaceous Gambier Group underlies the area and forms part of the Callaghan Creek roof pendant within diorite and granodiorite of the Jurassic to Tertiary Coast Plutonic Complex. Metavolcanic rocks comprise greenstone and chlorite schist while metasedimentary rock consist of biotite-quartz schist with minor quartzite, chert and local skarn near intrusive contacts.
A 15 by 3-metre zone of quartz flooding in foliated metavolcanics contains chalcopyrite-bornite-malachite-azurite mineralization. Assays of greater than 1 per cent copper, 1.23 grams per tonne gold and 31.5 grams per tonne silver have been obtained from this zone (Assessment Report 14252).
