Alamos Gold Inc., YoungDavidson Mine: Pebble Crushing

The SAG circuit was built without a pebble crusher and the mill was rejecting approximately 50T/hour of ungrindable pebbles. Over 5 years, 650,000 tonnes of gold bearing pebbles had been milled, rejected and stockpiled. The objective was to crush the existing 50t/hour pebble stream and to reprocess the 650kT pebble stockpile.
