Capsule Geology

Several small copper occurrences are reported on the ridge east of Lynn Creek and south of the Needles, including the Swayne Copper and Mountain Lion groups (refer to 092GSW001).

The mineralization located on the ridge east of Lynn Creek consists of chalcopyrite and pyrite disseminated along northeast trending shear zones in narrow bands of silicified limestone of the pre-Jurassic Twin Island Group. The zones are exposed over a few metres with a maximum width of less than 2.4 metres. Host rock includes calcareous schist.
