The Pebble Gold occurrence is located on a ridge on the south side of Muchalat Inlet, approximately 1.5 kilometres east of Ous Point.
The area is underlain by undivided sedimentary rocks of the Mississippian to Permian Buttle Lake Group. These have been intruded by granodiorite of the Jurassic Island Plutonic Suite.
Personal communication with Irving Ward of Pebble Gold indicates a roughly north-south trending shear zone in granodiorite, ranging in width from 10 to 30 centimetres, with quartz-infilling hosting gold- bearing pyrite and values of lead, zinc, silver and copper.
Some stripping has been done in the past by unknown operators. In 1981, Dynamic Oil Ltd. completed a program of geological mapping, rock, soil and silt sampling and airborne geophysical surveys on the area as Wyn claims.
