An extensive, complex shear system occurs in intrusive and gneissic volcanics and metasediments of the Coast Plutonic Complex. Gold associated with pyrite occurs in quartz-ankerite-sericite- sulphide veins within the shear zone. The Diabase showing is located in the southern part of the north- south trending shear system, about 2700 metres south of the Surf Inlet Mine (103H 027). A 1 metre wide quartz vein, occurring within sheared and altered diorite, is cut by a 3 metre wide diabase dyke. A 70 centimetre sample across the vein assayed 4.4 grams per tonne gold, 24.4 grams per tonne silver and 0.0015 per cent tellurium (Assessment Report 15377).
