The Lizard Lake showing is located slightly east of the lake, 15 kilometres southeast of Port Alberni.

Basaltic flows and pillowed basalt of the Triassic Karmutsen Formation of the Vancouver Group are underlain by a complexly inter- layered succession of volcanics and sediments of the Sicker and Buttle Lake Groups. These include limestones and marbles of the Lower Permian to Upper Pennsylvanian Mount Mark Formation and basaltic flows, agglomerates, bedded tuffs and andesite of the Upper Devonian McLaughlin Ridge Formation.

Chalcopyrite and some malachite occur in quartz-carbonate string- ers within epidotized shears in fractured, silicified, carbonate altered andesite. Massive sulphides occur in a tuffaceous pyritic chert layer (pyritic-dacitic-cherty-tuff-exhalative-horizon) below the quartz vein-bearing andesite.

Gold mineralization is associated with quartz veining and cross- cutting small fault structures. The north trending Williams Creek fault occurs in the area. The faults are associated with siliceous, calcareous and ankeritic alteration zones which average 3-4 metres in width and sometimes contain up to 3 per cent pyrite.

The Discovery showing assayed 4.46 grams per tonne gold, 24 grams per tonne silver and 0.13 per cent copper over 2.0 metres (Assessment Report 8981). A diamond-drill hole (DDH 84-5) intersected the chert horizon with sections assaying up to 1.13 grams per tonne gold and 3.6 grams per tonne silver over 1.8 metres (Assessment Report 14880). A chip sample (#62556), just east of the discovery showing, across 0.4 metres of a quartz splay vein and gouge assayed 0.24 per cent copper, 0.26 per cent zinc, 0.21 per cent lead, 130 grams per tonne silver and 1 gram per tonne gold (Assessment Report 18314).
