The Priam 3NE area is underlain by Upper Triassic marine sedimentary rock and volcanic rock of the Stuhini Group. The Stuhini package is intruded by a north-trending elongate quartz monzonitic mass to the immediate north, which is related to the Mount Dunn occurrence (104B 079). Lower Jurassic andesitic rock of the Hazelton Group is mapped north of the Priam area and west of the Mount Dunn prospect.
Reconnaissance prospecting in 1987 located an area of brecciation and silicification in the northeast corner of the Priam 3. A sample from a shear zone of brecciated grey quartz stringers and pockets of massive pyrite and chalcopyrite assayed 0.25 gram per tonne gold, 14.1 grams per tonne silver and 0.84 per cent copper (Assessment Report 19703).
