A 4.5 to 6.0 metre wide, east trending, felsite dyke cuts massive biotite granodiorite and lamprophyre dykes of the Cretaceous to Tertiary Coast Plutonic Complex. Quartz veins, 0.2 to 1.4 metres wide, occur for several hundred metres along either side of the dyke.
The Society Girl vein, a continuation to the west of the St. Paul vein (103I 098), occurs on the hangingwall side of the dyke. The vein is sparsely mineralized with pyrite, chalcopyrite, and galena. A 76 centimetre sample assayed 6.9 grams per tonne gold and 17.1 grams per tonne silver (Minister of Mines, Annual Report 1914). A sample of a quartz vein, which is likely part of the Society Girl vein, assayed 0.3 grams per tonne gold, 13.7 grams per tonne silver, 0.01 per cent copper, 1.08 per cent lead, and 0.02 per cent zinc (Assessment Report 13104).
In 1986, sample TT-45 was collected from the quartz vein exposed in the adit on the Society Girl claim and assayed 1.19 grams per tonne gold. The quartz vein contains massive pyrite and trace to 2.0 per cent chalcopyrite and galena across a 70 centimetre width (Di Spirito, et al., 1986).
The Sadie showing, located just north of the Society Girl, is comprised of a 1.0 metre wide quartz vein containing chalcopyrite, pyrite, malachite and azurite. A 30 centimetre sample taken from this vein in 1929, assayed trace gold, 55 grams per tonne silver and 9.0 per cent copper (Minister of Mines Annual Report 1929, page 78).
Mineralogical studies of the Society Girl quartz vein shows that it also contains small amounts of covellite and arsenopyrite. Sphalerite is locally abundant within this vein. Chalcopyrite occurs as irregular masses up to 2 centimteres in diameter with associated malachite and azurite. Goethite occurs as a minor alteration product of pyrite in the western portion of the Society Girl vein (DiSpirito et al. 1986).
