Two shafts were sunk on a small copper prospect in Gardner Bay, on the west side of Bowen Island. The main shaft is reported to have intersected a thin seam of bornite along a shear zone in metavolcanic rocks of the pre-Jurassic Bowen Island Group. The shaft was reported to be about 23 metres deep and is now flooded. The reported mineral- ized showing has not been verified.
A limited amount of ore was taken, and shipped, from a stope 9 metres long (Property File - Brewer, M. 1907).
