Capsule Geology

The Copper Bluff showing is situated on the east bank of the Similkameen River, 14 kilometres south of Princeton.

This showing occurs in biotite augite porphyritic micromonzonite of the Early Jurassic Lost Horse Intrusions. The rock is cut by fractures and shears containing pink orthoclase. One prominent shear zone, 1.8 to 2.4 metres wide, and 60 metres above the river on the Copper Bluff Crown-granted claim, contains blebs and irregular masses of bornite in a gangue of orthoclase. Anomalous gold and silver values are reported to accompany this copper mineralization (Minister of Mines Annual Report 1898, page 1113).

Percussion drilling to the north, near the south end of the Copper Cliff Crown-granted claim, encountered low-grade copper mineralization.

The showing was prospected as early as 1898. Cumont Mines Ltd. carried out geological mapping, induced polarization and soil surveys, and percussion drilling in 1968.
