Capsule Geology

The claim area is underlain by Upper Triassic to Middle Jurassic Hazelton Group greenstone, metasediments, amphibolites, gneiss and marble. Diorites and granites are exposed along the eastern margin of the Coast Range batholith.

Locally the A Zone hosts disseminated pyrite, chalcopyrite and pyrrhotite in a quartzite-limestone sequence. Grab samples assayed 0.62 to 2.33 grams per tonne gold.

About 200 metres west of the A Zone, disseminated pyrite occurs in a sheared diorite. A grab sample assayed 6.38 grams per tonne gold.

About 750 metres to the east, the East Zone hosts pyrite and chalcopyrite in a quartz vein which is housed in a shear zone. The shear lies within a siliceous mafic volcanic. In 1986, a sample assayed 6.93 grams per tonne gold and 0.66 per cent copper.
