The Cu-Moly property is located along the western bank of the Lillooet River, south of Little Lillooet Lake and Billygoat Creek. The region is underlain by volcanic and sedimentary rocks of the Lower Cretaceous Fire Lake Group, correlative with the Gambier Group, and intruded by dioritic rocks of the Jurassic to Tertiary Coast Plutonic Complex. The property is situated along a narrow fault-bounded block of Fire Lake Group rocks which, in this area, consist mainly of metamorphosed argillite and interbedded tuff. Diorite and dykes of possible lamprophyric composition intrude the bedded rocks.

Three mineral showings have been located. The Number 1 and Number 2 showings consist of gold-bearing quartz stringers and lenses in shear zones, mineralized with pyrite, chalcopyrite and bornite. The Number 1 showing is developed in a shear, striking 340 degrees and dipping steeply west, at the contact of argillaceous tuff and diorite. The Number 2 showing occurs in a schistose section in the footwall of a shear in siliceous tuff. The northwest trending shear contains pyrite, challcopyrite and galena.

At the Number 3 showing, molybdenite-pyrite-chalcopyrite mineralization occurs as blebs, disseminations and along fractures in an intrusive dioritic breccia (200 by 300 metres) which has developed around a small diorite plug. A northwest trending shear zone through the breccia was sampled and was found to grade up to 69.2 grams per tonne gold and 781 grams per tonne silver over a width of 10 centimetres (Tully, 1985). The breccia averages 0.3 per cent copper and 0.06 per cent molybdenum. Trenching and drilling were conducted on all the showings.
