The property is underlain by Devonian to Permian age Fennell Formation rocks consisting of cherts and phyllites in the west and Mississippian age part of the Eagle Bay Formation rocks consisting of phyllites, siltstones and sandstones in the east. A 150 degree striking and steeply dipping fault, separating the two formations, has sheared and silicified the metasediments. The rocks generally strike 160 to 170 degrees and dip 50 to 90 degrees to the west, and in places, display rusty carbonate alteration. To the southeast is a Mississippian limestone unit.

Mineralization consists of sphalerite and galena with minor pyrite and chalcopyrite in quartz veins within highly sheared phyllite pyritic quartzite and ferruginous limestone. The quartz veins are a few centimetres to a few metres wide and generally strike north- northwest with near vertical dips.
