Capsule Geology

The Hawthorn Lake property is located between Corrigan Creek and Lizard Pond, approximately 2 kilometres north of Hawthorn Lake.

The area is underlain by mafic volcanic rocks of the Triassic Karmutsen Formation (Vancouver Group). These are intruded by large granodiorite sills, stocks and dikes of the Jurassic Island Plutonic Suite. Local inliers consist of Triassic Quatsino Formation (Vancouver Group) sedimentary limestones overlain by volcanics of the Jurassic Bonanza Group, and sandstones, shales and conglomerates of the Cretaceous

Nanaimo Group.

Locally, grey, green and bronze fine-grained and medium-grained, silicified, chloritic mafic volcanics with quartz stockwork contain sulphides. They are named the Rock Vein SE, Rock Vein NW, Last Vein and Snag Vein, respectively. The veins contain dilation zones with clots of sulphides including chalcopyrite, pyrite, bornite, and possibly sphalerite. Malachite is common on road cut exposures along the shears hosting the veins.

In 2010, Jacques Houle, on behalf of Chile Gold & Copper Inc. completed a program of geochemical sampling, consisting of 16 rock and 28 moss mat samples. Four of the sixteen grab samples contained greater than 1 per cent copper with returned analyses of 1.195 per cent copper, 2.68 per cent copper, 2.35 per cent copper, 2.06 per cent copper and 0.221 parts per million gold in four of the samples. It was noted that these samples are not representative of in-situ grades (Assessment Report 32329).
