The Happy Jack occurrence is located on the east side of the Benson River, approximately 800 metres south of the river mouth on Benson Lake.

The area lies within Upper Triassic Vancouver Group, Karmutsen Formation volcanics comprised of fine to medium-grained andesite, basalt and porphyritic flows. The volcanics are conformably overlain by Upper Triassic Vancouver Group, Quatsino Formation limestones. Bedded rocks strike northwest and dip about 35 degrees to the west. The Vancouver Group rocks are intruded by the "Coast Copper stock" of the Lower to Middle Jurassic Island Plutonic Suite. The contact dips 70 degrees to the northeast. Volcanic rocks have undergone pyrite, sericite, epidote and carbonate alteration.

The "Coast Copper" diorite gabbro stock of the Jurassic Island Plutonic Suite lies approximately 1 kilometre to the west.

The occurrence is reported to host skarn mineralization similar to the Old Sport mine (MINFILE 092L 035). Isoclinal folding of Upper Triassic Vancouver Group, Karmutsen Formation andesite and Quatsino Formation limestone, has repeated the stratiform skarn chalcopyrite-magnetite horizon which host the Old Sport deposit.

In 1988, a sample assayed 14.47 copper, 0.79 grams per tonne gold, 26.4 grams per tonne silver and 65.16 per cent iron (Assessment Report 18619).
