The Pebble Beach North shear zone showing is hosted in Stuhini Group andesitic volcaniclastics.

The showing consists of a 10 to 70 centimetre wide shear zone with 1 to 2 centimetre wide quartz and calcite veinlets and podiform massive pyrite and chalcopyrite. The shear zone has been strongly oxidized to goethite, jarosite, and minor malachite. The structure strikes 015 degrees/76 degrees east dip for 14 metres before being faulted to the north and covered by overburden to the south. This shear zone contains up to 6 per cent pyrite in a 40 centimetre wide alteration halo on each side of the vein. In 1990, a number of chip samples were taken across the structure, including both the shear zone and altered wallrock. A sample across 1 metre assayed 1.06 grams per tonne gold 11 grams per tonne silver, 0.12 per cent copper, 0.035 per cent lead, 0.014 per cent zinc and 0.61 per cent arsenic (Sample 32586, Assessment Report 21061).
