The Keno 9 showing is located 15 kilometres south-southwest of Nelson between the Mammoth (082FSW211) and Fern (082FSW183) properties. An old adit and opencut from unknown exploration are present on the claim.

The area is underlain by augite basalt flows and flow breccias of the Elise Formation and siltstone, sandstone, conglomerate and argillite of the Hall Formation, both of the Lower Jurassic Rossland Group.

Two east striking quartz veins, in volcanic rocks near the sedimentary-volcanic contact, comprise the showing. The main vein, 1.37 metres wide, is exposed by the old workings. The vein strikes 250 degrees and dips 65 to 70 degrees north. A similar secondary vein, 0.20 metre wide, occurs 2 metres to the north. An adit, 50 metres north of the main vein, is cut on a copper-rich similar quartz vein.

Mineralization consists of chalcopyrite, tetrahedrite, bornite and possibly cuprite as disseminated to semi-massive pods within the veins.

Sample M1 from the adit dump assayed 1.12 grams per tonne gold, 84.5 grams per tonne silver and 5.31 per cent copper (Assessment Report 18235). A selected sample from the main vein dump assayed 5.4 grams per tonne gold, 8.0 grams per tonne silver and 1.106 per cent copper (Assessment Report 18235).
