Capsule Geology

Mineralization is associated with a quartz vein within granitic rocks of a Jurassic Topley Intrusion. The vein has a width of 7.6 centimetres to 0.9 metres and strikes 025 degrees and dips 25 degrees west. It is exposed for about 107 metres. Mineralization occurs in small quantities at widely scattered points along the vein and in quartz lenses branching from the main vein. Scheelite, sphalerite, and galena mineralization have been reported. Five samples were collected in 1943 over widths of 35.5 centimetres or less from a short adit along branch lenses. These assayed trace to 17.14 grams per tonne gold, nil to 78.86 grams per tonne silver, 0.1 to 5.6 per cent lead, 0.9 to 20.2 per cent zinc and 5.85 to 20.28 per cent tungstic oxide (Bulletin 10, page 71).
