The Ham occurrence is located on eastern- facing slopes overlooking the Clayoquot Arm of Kennedy Lake, approximately 2.5 kilometres south east of Duck Island.
The area is underlain by agglomerates and basalts of the Upper Triassic Karmutsen Formation (Vancouver Group) with associated Permian and Upper Triassic limestone units of the Quatsino Formation. A Tertiary diorite stock intrudes the above units.
Locally, black copper mineralization (chalcocite?) occurs as inter-pillow material, and north to northwest- trending quartz± epidote veins containing chalcopyrite, malachite and pyrite cut Karmutsen agglomerates, feldspar porphyries and pillow basalts.
In 1990, Homestake Canada completed a program of geochemical sampling and geological mapping on the Ham 2-4 claims, which identified copper mineralization on newly constructed logging roads. Assays reported were up to 6.3 per cent copper, 0.068 gram per tonne gold, 5.6 grams per tonne silver, 0.0000292 per cent platinum and 0.0001165 per cent pladium (Assessment Report 20114).
