Host rocks for the mineralization are dolomitized limestone within the metavolcanic-phyllite division (Bulletin 71) which is probably correlative to the Index formation of the Lardeau Group (Lower Paleozoic).

Mineralization occurs as narrow stringers or blebs of galena, sphalerite, pyrrhotite or pyrite, with silver in calcite marble, calc-silicate gneiss or quartz veins that cut the marble and gneiss. The mineralization appears to be stratabound, distributed erratically through a pure to very siliceous marble/calc-silicate gneiss layer several tens of metres thick.

A second, similar type of mineralization occurs about 1000 metres to the east, within a limestone unit which is a member of the carbonate-phyllite division (Bulletin 71). Mineralization consists of stringers of pyrrhotite with associated sphalerite adjacent and below the limestone unit. The zone can be traced for 350 metres across cliff faces and appears to be up to 4 metres wide (Assessment Report 6712).

A weighted 5 metre drill hole assay averaged 1.85 grams per tonne gold, 21.0 grams per tonne silver, 1.85 per cent lead, and 0.87 per cent zinc (Assessment Report 6712).
