The Pass showing is located at 920 metres elevation, 500 metres east of Kilpoola Lake and approximately 7.5 kilometres west of Osoyoos, British Columbia.

Regionally, the Pass showing is underlain by north striking and moderately west dipping Carboniferous to Permian Kobau Group metavolcanic and metasedimentary rocks. The Kobau Group consists of schist, chlorite schist, quartzite, amphibolite and minor marble. The Kobau package is bound to the east by the Middle Jurassic Nelson intrusions and to the west by the Jurassic Kruger batholith composed mainly of medium to coarse-grained nepheline syenite. The nepheline syenite is a mafic phase of the Kruger batholith with high iron content present mainly as very fine grained (-200 mesh) disseminated magnetite.

The showing consists of scattered quartz lenses and veins containing copper, lead, gold and silver mineralization.

In 1973, Cone Properties Ltd. conducted an extensive property exploration program consisting of geological mapping, a magnetometer geophysical survey, a 3100 sample geochemical soil survey and 10 percussion-drill holes totalling 821 metres. No assessment record detailing the results of this work could be found. In 2012, Venza Gold completed a program of soil sampling on the area as the OS Gold claim.
