The Olympus West showing is located in the Whitewater Creek basin, 3.75 kilometres northwest of the Highland Surprise occurrence (082KSW037). The town of Kaslo lies 28 kilometres to the southeast.

Andesitic volcanics of the Permian Kaslo Group under underlie the Olympus West showing. Locally these volcanics may be fragmental or tuffaceous. Serpentinite, locally hosting chrysotile along hairline fractures, occurs to the northeast. Serpentinite contacts appear to be faulted. Small outcrops of coarse grained hornblende porphyry and quartz feldspar porphyry (dike?) were noted nearby. A major shear zone trending 330 degrees was noted northeast of this showing, intersecting the serpentinite body along its western margin.

The Olympus West showing consists of the northwestern vein of two subparallel veins (see Olympus East, 082KSW174), roughly 175 metres apart along strike. The EK 78910 occurrence (082KSW066) lies 850 metres to the south-southeast and may be genetically related. The vein strikes 048 degrees and dips 60 degrees south and is developed by a 15-metre adit. At this location the vein is approximately 10 centimetres wide and composed primarily of quartz and hematite. Dump material from the adit contains traces of galena and pyrite. Dark grey andesite of the Kaslo Group and a quartz feldspar porphyry dike are hostrocks of this vein. The veins have also been exposed by trenching on surface. Here, sulphide concentrations reach 10 per cent sphalerite, 2 per cent galena and 2 per cent chalcopyrite (Assessment Report 12167).

A select grab sample (OLY-P-4-R) of vein material excavated in the trench yielded assay values of 185 grams per tonne silver, 3.90 per cent lead, 9.32 per cent zinc and 0.95 per cent copper (Assessment Report 12167).
