The area of the occurrence is underlain by three units of the Mississippian Antler Formation, Slide Mountain Group. The lowest sequence is comprised of quartz mica schist and micaceous quartzite. Next highest is a medium grained chloritic feldspathic greenstone and chloritic schist which in turn is overlain by a black pyritiferous argillite and phyllite sequence. The argillite and phyllite unit is pervaded by quartz in the form of veins, stringers, lenses and boudins. Selvages, masses and disseminations of galena, sphalerite and pyrite are associated with the quartz bodies. Coarse crystalline masses of mineralization 10 to 20 centimetres in diameter occur in boudins.

A large quartz vein (1 to 2 metres wide) occurs at the mid-level of a bluff on the north side of Paput Creek. A weighted average of samples taken in 1982 across 4.8 metres of this vein was 41.136 grams per tonne silver, 0.1714 grams per tonne gold, 2.88 per cent lead and 0.04 per cent zinc (Assessment Report 10397).
