Keewatin-type mafic to intermediate meta volcanics  are  cut  by  north-trending  diabase  dikes. Gold occurs in the Ribble Vein which strikes north and  dips 600W. The vein has been  intensely folded and some drag folds pass into small faults. The average width of the vein is about 4 feet, although a 23- foot width  of quartz and schist has been  reported. The wall rock consists of chloritic schist. Moiled  samples  have  yielded  values of 0.50 ounce of  Au  per  ton  over  an  average  width  of 4.2  feet and  0.39  ounce  of  Au  per  ton  over  an  average width of 4.1 feet.
