The Oyama 2 showing is located on the west side of Okanagan Lake about 8 kilometres west of Okanagan Centre.

The area is underlain by Eocene volcanic and sedimentary rocks of the Penticton Group and Middle Jurassic granitic rocks. These comprise andesite, sandstone, conglomerate, argillite and quartz monzonite and granodiorite.

The Eocene sediments are slightly enriched with uranium mineralization. One 0.5-metre chip sample from an outcrop assayed 0.017 per cent U3O8 (Assessment Report 6727). A percussion drill- hole, entirely in volcanic rocks, recovered no radioactive rock chips.

Mapping, sampling and one drillhole were completed in 1978 by Du Pont of Canada Exploration Ltd.
