The Pebble Beach South shear zone showing is hosted in Stuhini Group andesitic volcaniclastics.
The Pebble Beach South showing is very similar to Pebble Beach North showing (about 700 metres north), consisting of a quartz vein with 2 to 10 per cent pyrite, in a 20 to 40 centimetre wide shear zone that has been strongly oxidized to goethite and jarosite. The vein is 5 centimetres wide, striking 345 degrees/80 degrees northeast dip for 7.0 metres. The andesitic agglomerate wallrock is mineralized with 1 per cent to 5 per cent pyrite, and is oxidized within 1.0 metres of the shear zone. A select grab sample of a pyritic pod in this vein (459385) assayed 8.16 grams per tonne gold (Assessment Report 19783, 21061).
