The claim is underlain by black argillaceous sediments with lesser cherty argillite, volcaniclastic wacke, sandstone and conglomerate of the Noel(?) and Hurley(?) Formations of Upper Triassic age. They exhibit a wide range of attitudes, suggesting considerable local folding. A number of narrow quartz veins, barren of sulphides, occur at scattered locations. One short adit on the northern edge of the claim exposes a 4 metre wide quartz vein stockwork in argillite. Minor pyrite on vein margins was noted.
