The Kitchener skarn deposit is underlain by alternating bands of volcanics and limestone of the Upper Triassic Karmutsen Formation, Vancouver Group. A wide belt of granodiorite of the Early to Middle Jurassic Island Plutonic Suite occurs to the northeast of the occurrence.

Magnetite, pyrrhotite and chalcopyrite occur in a hornblende gangue, replacing limestone along limestone-volcanic contacts, a few hundred metres from the granodiorite. Ore outcroppings have been exposed along three such contacts, in a width of about 60 metres, at intervals for 180 to 213 metres.

In 1929, development work consisted of surface stripping and trenching and a crosscut tunnel driven for 24 metres. In this year, 168 tonnes of ore was mined from which was produced 5,366 kilograms of copper, 124 grams of gold and 653 grams of silver (Mineral Policy data).

On the nearby Bell claim, at 90 metres elevation in a railway cut, pyrite and chalcopyrite ore occur within a shear zone within the volcanics. This deposit was mined along with the Kitchener deposit, and the 18 tonnes produced from it are included in the above Kitchener production figures.
