The Heather occurrence is located in the headwaters of the Cruickshank River, approximately 23 kilometres west of Courtenay.
The area is primarily underlain by basalt of the Upper Triassic Vancouver Group, Karmutsen Formation which consists of flows, pillow breccia, aquagene tuff, and some thin sedimentary layers. This unit was intruded by a granodiorite stock of the Jurassic Island Intrusions and bodies of quartz diorite thought to be related to the Late Eocene to Early Oligocene Mount Washington Intrusive Suite (Massey, N., Personal Communication).
The North showing is located at the foot of a cliff and consists of a quartz-epidote altered zone of sheeted and braided fractures and seams which strike 075 degrees and dip close to vertical. The miner- alization comprises seams and veins of near massive chalcopyrite and some pyrite. Locally the vein widths range from 0.6 to 1.8 metres. A sample taken across 0.9 metres assayed 4.6 per cent copper, 0.17 gram per tonne gold and 15.43 grams per tonne silver (Assessment Report 2762).
The South showing, 120 metres to the southeast, is exposed in the floor and south wall of a deep, narrow gully and consists of a mineralized shear zone striking 070 degrees and dipping 80 degrees to the south. The principal exposure consists of 1.5 metres of strongly sheared and chloritized massive to porphyritic basalt containing pods, stringers and disseminations of pyrite, chalcopyrite, chalcocite, minor bornite, malachite and limonite. One 0.6 metre sample assayed 4.6 per cent copper, 1.54 grams per tonne gold and 28.80 grams per tonne silver (Assessment Report 2762).
