The WP-Cati showing is located 1 kilometre west of the Brenda mine (092HNE047) tailings pond, approximately 19 kilometres northwest of Peachland.

The showing consists of copper (chalcopyrite?) mineralization exposed in outcrops of a porphyritic quartz diorite of the Early Jurassic Pennask Batholith, locally known as the Brenda stock. The mineralization is believed to be hosted by quartz veins. Trachyte dikes and post-mineralization lamprophyre cut across the property.

During the exploration boom of the late 1960s this showing was held by Buttle Lake Mining Ltd. and Trojan Consolidated Mines Ltd. In 1967 they carried out a limited induced polarization survey on an area about 1 kilometre to the north of the WP-CATI showing. Weak anomalies were identified, which were subsequently drilled later that year. The results of the drilling are not on record.
