The Billyo "massive sulphide" zone is hosted in Mississippian to Jurassic Bridge River Complex (Group) metasediments. Trenching exposes a garnet-diopside skarn in iron-oxidized vesicular felsite breccia containing lensoid pyrite, pyrrhotite, magnetite and chalcopyrite. An adit and nearby drill holes located pyrite and magnetite stringers but failed to reach massive sulphide mineralization. Over 30 centimetres, sulphides geochemically analysed 0.27 grams per tonne gold, 3.43 grams per tonne silver and 0.06 per cent copper and a grab sample ran 5.9 grams per tonne gold, 5.14 grams per tonne silver and 0.55 grams per tonne copper.

The Moly zone, on the west side of the Billyo zone, contains fracturing and quartz veining adjacent to or within a broad aplite dyke surrounded by a pyrite/gypsum halo. Mineralization consists of pyrite, pyrrhotite (dendritic), manganese staining, ferro-molybdenum staining and arsenopyrite.
