The mayors of MRC de Papineau unanimously accepted a recommendation from Quebec's Ministry of Natural Resources Wednesday to put up barriers to permanently secure a former mine that had become popular with weekend adventurers.
Paulette Lalande, the prefect of the MRC de Papineau, told Radio-Canada that barriers anchored in the ground will be placed at the entrance of the old quartz mine so that no one can get there.
