Capsule Geology

Quartz veins mineralized with bornite, chalcopyrite and mala- chite occur in andesitic rocks of the Jurassic Hazelton Group. The Emma vein, at about 140 metres elevation, strikes 105 degrees and dips 25 to 40 degrees north. It is up to 60 metres long and varies from 0.3 to 2 metres wide. Several faults offset the vein. A 40 centimetre channel sample taken across the vein assayed 5.5 grams per tonne gold and 25 grams per tonne silver (Geological Survey of Canada Memoir 205).

The I.X.L. vein, about 300 metres to the east, strikes 120 degrees and dips 65 degrees south. It is exposed for about 30 metres and is up to 2.1 metres wide. A 71 centimetre channel sample taken across the best mineralized section assayed 0.7 grams per tonne gold, 86.4 grams per tonne silver and 1.21 per cent copper (Geological Survey of Canada Memoir 205).

Scheelite has been reported from the Emma workings.
