The Nelson showing is located 160 metres west of Wolfe Creek and 13 kilometres south of Princeton.

The area is underlain by the eastern facies of the Upper Triassic Nicola Group, comprising 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.

Micromonzonite/latite of the Lost Horse Intrusions is irregularly mineralized with disseminated pyrite and chalcopyrite. The strongest mineralization is exposed in a 34-metre long tunnel, 160 metres west of Wolfe Creek. A chip sample taken along the south wall of this tunnel assayed 0.28 per cent copper over 23 metres, and a selected grab sample assayed 1.97 per cent copper and 0.40 gram per tonne gold (Geological Survey of Canada Memoir 171, page 37).

This showing was explored by three tunnels and a number of trenches, excavated some time between 1916 and 1934. Cumont Mines Ltd. carried out soil, magnetometer and induced polarization surveys in 1968. Newmont Exploration of Canada Ltd. completed soil and geophysical surveys over the showing in 1987.
