The North showing is underlain by grandodiorite of the Max stock, which intrudes sedimentary rock of the Middle Jurassic to Lower Cretaceous Bowser Lake Group. Mineralization consists of veining within the granodioritic Max stock. There are calcite veins up to 80 centimetres thick containing up to 10 per cent galena and arsenopyrite.
The vein is exposed in a 3 metre long trench trending 030 degrees.
