A small granite quarry was developed on the south shore of Fox Island, just south of Hardy Island in Jervis Inlet, around the turn of the century.

The Fox Island granodiorite, of the Jurassic to Tertiary Coast Plutonic Complex, is visibly lighter in appearance than Kelly Island (092F 196) stone and slightly coarser. It is medium-grained, light grey in colour on fresh surfaces, and weathers black. Knots of dark mafic minerals (biotite and hornblende) are up to 10 by 20 centimetres and less than 0.5 per cent of total volume. The quarry consists of an opening approximately 30 metres long by 3.5 to 11 metres high developed along the shore of Fox Island. Three sets of steeply dipping joints are recognized: east-northeast dipping north; east-northeast dipping south; and south-southeast dipping east. Over 90 per cent of the joints and fractures measured, were greater than 50 centimetres apart and almost 80 per cent were greater than 100 centimetres apart. Potential reserves extend for at least 30 metres northeast of the face.

The stone was used primarily in the construction of the Winch Building in Vancouver.

There has been small-scale, steady production from this quarry since 1990. Production statistics are unavailable.

Quadra Stone Company Ltd. operates the quarry.
