The IXL showing occurs in the northwest corner of Porcher Island, a few hundred metres southwest of the Surf Point Mine (103J 017).

Several east-southeast striking auriferous pyritic quartz veins are associated with shear zones in the western part of a 2.8 kilo- metre diameter Cretaceous to Tertiary quartz diorite stock of the Coast Plutonic Complex. The stock intrudes Paleozoic to Mesozoic mixed volcanic and older plutonic rocks. The veins vary in width from 5 centimetres to 1 metre and up to 24 metres in length. A representative sample from an ore dump assayed 208 grams per tonne gold and 55 grams per tonne silver (Minister of Mines Annual Report 1930, page 72).
