The Steep 3 showing is underlain by lower Paleozoic Sicamous Formation (Mount Ida Group) phyllitic, argillaceous limestone, phyllitic calcsilicate skarn, garnet skarn, banded to massive calcsilicate rocks and quartz sericite phyllite. These have been intruded by late quartz feldspar porphyry dikes. The skarns are an extension of skarns on the Steep occurrence (082M 118) to the north.

The strike of bedding varies from 270 degrees to 360 degrees, suggesting a broad fold structure. Dips average about 50 degrees north to east.

A trench exposes galena mineralization in massive calcsilicate skarn and quartz veining. Pyrite and chalcopyrite? were also observed. A sample from an adjacent quartz porphyry dike analysed 445 parts per billion gold (Assessment Report 19514, page 7).
