Capsule Geology

The Dot Fraction claim is located on Racoon Island in Indian Arm. The island is underlain by granitic rocks of the Jurassic to Tertiary Coast Plutonic Complex.

Several open cuts and a 2.4 metre shaft occur near the centre of the island towards the northern shore. The open cut exposes oxidized quartz. A selected sample, in 1935, from a small pile of this mater- ial assayed 1.37 grams per tonne gold (Property FIle - Richmond, M.E. (1935)).

The oxidized quartz hosts pyrite mineralization which occurs in fine-grained dioritic rocks near a basic phase of the intruding granodiorite.
