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.
