Lot 3311 is underlain Lower Cretaceous Skeena Group sediments (Kitsun Creek Formation) comprised of andesitic tuff, greywacke, shale and conglomerate. The Skeena Group is intruded by a Late Cretaceous to Tertiary porphyry stock and associated dikes.

Locally, the property is underlain by schists which are intruded by a wide, fine-grained quartz porphyry dike. Mineralization occurs in a fracture zone in the schist about 15 metres from the dike and roughly paralleling it. Mineralization occurs as fissure vein in- fillings in the schist, varying from 0.3 to 1.2 metres in width and striking 100 degrees. Sulphide mineralization consists of sphal- erite, galena, jamesonite with minor tetrahedrite and pyrite. The galena and tetrahedrite carry good silver values.

In 1918, a sample across 0.6 metres in an open cut assayed trace gold, 761.1 grams per tonne silver, 2 per cent lead, and 34.8 per cent zinc. A selected sample of the mineralization assayed 0.68 grams per tonne gold, 4278.8 grams per tonne silver, 46 per cent lead, and 20.4 per cent zinc (Minister of Mines Annual Report 1918, page 118).
