The VMS property is underlain by a northwest striking, moderately to steeply southwest dipping sequence of metasedimentary rocks of the Upper Mississippian to Permian Milford Formation near the northern margin of quartz monzonitic intrusive rocks of the Middle Jurassic Kuskanax batholith. The metasediments are predominantly blue-grey to black, graphitic phyllite and argillite with pyrite commonly found as streaks of very fine grained material paralleling bedding or foliation. Smaller amounts of light grey to dark grey quartzites, thinly laminated quartzitic siltstone and phyllitic quartzites occur in the black sequence. Minor bands of recrystallized, blue-grey limestone are found at various places within the light coloured quartzitic sequence. A series of highly deformed, biotite-quartz-feldspar schists and gneisses of the Cambrian to Devonian Lardeau Group also occur and contain bands of calcareous material (largely converted to marble or skarn). The marble is an extremely coarse mixture of calcite crystals and muscovite. The skarn is a dense, green-brown colour with garnet and tremolite or diopside and is frequently rusty weathering from contained pyrite and pyrrhotite. Numerous aplitic and felsic dikes intrude the metasediments and are probably genetically related to the Kuskanax batholith.

At the VMS 9 showing, copper mineralization occurs in an outcrop of quartzite and phyllitic siltstone and consists of malachite on foliation surfaces and minor disseminated grains of chalcopyrite in quartz veins or layers conformable with the bedding. The mineralization occurs sporadically over a 15 to 30 centimetre width and can be traced intermittently along strike for about 23 metres. The on-strike extensions of this zone were prospected but no further mineralization was found.

The VMS claims were staked in 1971 on behalf of Pan Ocean Oil Ltd. to cover geochemically anomalous molybdenum values from reconnaissance prospecting. Work carried out in the same year consisted of prospecting, geological mapping and soil and rock sampling. In 1978, Newmont Mines Limited staked the TL and Ash claims to cover the showings and conducted geological mapping and silt and rock sampling in 1978 and 1979.
