The Priam 2 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.

A grab sample from a one-metre wide quartz vein in an area of andesitic rocks yielded 0.21 per cent copper (Assessment Report 19703). The vein is reported to contain minor malachite and a trace of pyrite.

Refer to Priam 1 (MINFILE 104B 620) for details of a common work history.
