The Orlean showing is located in a roadcut 11.7 kilometres north of Lytton on the Lillooet highway.

The area is underlain by Triassic Mount Lytton Complex dioritic intrusives and Middle and Upper Cretaceous Spences Bridge Group volcanics, slates and sandstone. Major faults lie along the Fraser River. A shear zone striking 130 degrees and dipping 50 degrees northeast, lies within black slate which lies within massive reddish sandstone. Malachite and azurite occur in fractures within slate. Uranium is reported to occur as metazeunerite (Geological Survey of Canada Economic Geology 16). A sample assayed 0.0045 per cent uranium oxide equivalent (Minister of Mines Annual Report 1955).
