The No. 67 showing is situated on the east bank of the Similkameen River, 17 kilometres south-southwest of Princeton.
The area is underlain by the eastern facies of the Upper Triassic Nicola Group consisting of mafic augite and hornblende porphyritic pyroclastics and flows. These rocks are intruded by diorite and monzonite, locally pyroxenite and gabbro, of the Early Jurassic Copper Mountain and Lost Horse intrusions.
This occurrence consists of a high-grade bornite showing in pegmatite and syenite of the Copper Mountain stock (Copper Mountain Intrusions). A hole drilled to a depth of 30 metres encountered a narrow section of bornite mineralization.
This showing was initially explored by an adit some time before 1934. Copper Mountain Mines Ltd. drilled one hole in 1960. Newmont Exploration of Canada Ltd. completed soil and geophysical surveys over the showing in 1987.
