The Frank showing is located 40 kilometres west of Nanaimo at the head of the Nanaimo River.

The area is underlain by volcanic rocks of the Upper Devonian McLaughlin Ridge Formation, Sicker Group (formerly lower Myra Formation) and sedimentary rocks of the Mississippian to Pennsylvannian Fourth Lake Formation, Buttle Lake Group (formerly upper Myra Formation). These have been intruded by late Triassic dykes and sills of unknown affinity.

The showing is hosted in rocks mapped as breccia, tuff and argillite; the actual host rocks are not described. Massive sulphide mineralization, pyrite and chalcopyrite are assumed, was discovered during a geochemical survey. The mineralization occurs in a north- east striking zone, outlined by the geochemical survey, 400 metres long and 100 metres wide. A sample assayed 3.6 per cent copper, 11.5 grams per tonne silver and 0.046 grams per tonne gold (Assessment Report 16585).
