A 1.5 to 4.5 metre wide shear zone, striking 045 degrees and dipping 70 degrees southeast, occurs in coarse grained granodiorite of the Cretaceous to Tertiary Coast Plutonic Complex. The zone, which is up to 300 metres long and 180 metres vertical distance, contains quartz lenses and veins mineralized with pyrite and chalco- pyrite. Associated alteration minerals include epidote, chlorite and biotite.

In the area of the main vein, remnants of older Mesozoic and Paleozoic sedimentary rocks, mainly greywacke, have been altered to greenstone. North trending faults, dipping 50 to 70 degrees west, cut the vein. Mineralization is erratic with lenses up to 2 metres and assays up to 7.7 grams per tonne gold and 14 grams per tonne silver (Assessment Report 11335). A grab sample assayed 4.2 grams per tonne gold, 26.1 grams per tonne silver and 1.20 per cent copper (Assessment Report 13104).

In 1926, about 27 tonnes of hand-sorted ore were shipped from the Golden Nib property. From this ore 1,493 grams of gold, 1,275 grams of silver and 302 kilograms of copper were recovered. Two tonnes of ore were shipped to the Provincial Government sampling plant in Prince Rupert between 1938 and 1941. This shipment produced 124 grams of gold and 62 grams of silver.
