The Independence showing is 800 metres southeast of the Similkameen River, 16 kilometres south of Princeton. The Idaho showing (092HSE096) lies 550 metres southwest of this occurrence.

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 Crown-granted claim is underlain mostly by syenodiorite of the Copper Mountain stock (Copper Mountain Intrusions). A trench exposes jointed syenodiorite cut by mylonitic zones, just west of the contact with biotite syenogabbro. Potassium feldspar porphyry dykes, 1.3 to 15 centimetres wide, occur in some of the northeast striking joints.

The dykes contain chalcopyrite and malachite as thin, short fracture fillings. The fractures generally trend west and dip steeply north. A grab sample from one of these dykes near the south end of trench TR-1 assayed 0.163 per cent copper (Assessment Report 2792, page 6).

Cumont Mines Ltd. conducted trenching and geological, soil and magnetometer surveys over this showing in 1966 and 1970.
