In 1999, Barker Minerals Ltd. discovered a 2 to 3-metre thick bed of sulphide-bearing limy quartzite, bounded by grey limestone. A grab sample from the showing, containing disseminated chalcopyrite, sphalerite and galena, assayed 3920 ppm copper, 1850 ppm lead and 838 ppm zinc (Exploration in BC 1999, p. 23).

The area is underlain by the Mississippian to Pennsylvanian Slide Mountain Group and the Upper Triassic to Lower Jurassic Quesnel River Group.
