The Olympia showing is located 150 metres west of Wolfe Creek and 13.5 kilometres south-southeast 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 several stocks of diorite and monzonite, locally pyroxenite and gabbro, of the Early Jurassic Copper Mountain intrusions.

Two trenches in hornblende andesite breccia of the Nicola Group contain minor chalcopyrite and pyrite. Material excavated from a shaft sunk near the trenches displayed a considerable amount of chalcopyrite and pyrite in a gangue of quartz (?) and magnetite. Some of this material is estimated to contain at least 2 per cent copper (Geological Survey of Canada Memoir 171, page 38). A grab sample from a shaft dump, containing some 27 tonnes of magnetite- pyrite-chalcopyrite-azurite ore, assayed trace gold and silver and 0.40 per cent copper (Minister of Mines Annual Report 1930, page 213).

This showing was first explored some time between 1900 and 1920. Newmont Exploration of Canada Ltd. completed soil and geophysical surveys over the showing in 1987.
