The PL 9 West showing area is underlain by marine sedimentary and volcanic rock of the Upper Triassic Stuhini Group. The stratigraphy is intruded by Eocene granite of the Major Hart Pluton and Early Jurassic monzodiorite to gabbro of the Texas Creek Plutonic Suite. Further west the area is underlain by Devonian to Permian sedimentary rocks of the Stikine Assemblage.
Sample 463258, which assayed 75.4 grams per tonne gold without significant silver or base metals, was taken from a shear zone in intermediate to mafic volcanic rock with a schistose texture that hosts finely disseminated pyrite and millimetre scale quartz veins.
Three samples (approximately two hundred meters north of sample 463258), were taken from a quartz vein with poddy aggregates of pyrite and chalcopyrite, which can be traced intermittently over 170 meters of strike length. Its width varies from 0.5 to 1 .0 metre, with an attitude of 304 degrees/90 degrees dip, and graded up to 1.13 grams per tonne gold with 0.64 per cent copper (Assessment Report 19534).
