The Project is located on the eastern margin of the Prairie Creek Embayment which is composed primarily of Lower Ordovician Whittaker Formation dolostones overlain by Silurian Road River Formation cherty shales and Cadillac Formation thinly bedded dolostone. Lower to Middle Devonian Arnica and Funeral Formation dolostones and limestones overlie this unit on the northern part of the property. Faulting and folding trends north-south in the property area, resulting in windows of older Road River and Whittaker Formation rocks being exposed along the core of the main anticline. Most of the numbered mineralized zones at Prairie Creek (VMS surface showings) occur within the Road River Formation shales.

The north-south trending Prairie Creek fault structure is traceable for a distance of over 10 km on the property along which twelve separate mineralized vein massive sulphide ("VMS") occurrences have been found. The bulk of exploration and development has occurred within Zone 3 (at the minesite) on one of these VMS occurrences. The mineralization within the vein is well developed where the vein cuts the Whittaker Formation and Road River Formation. Mineralization within the quartz vein consists of zinc-lead-copper with significant silver grades. The most extensive known vein occurrence is within Zone 3, where underground development on 3 levels has proven 940 m of strike length and diamond drilling has indicated a continuation of the vein for a further 1.2 km. The vein remains open to the north and is expected to continue, albeit at depth, for a further 4 km as evidenced by the Rico Showing, a high grade surface vein occurrence.
