LIKELY, C.-B. - Le gouvernement de la Colombie-Britannique a indiqué qu'il y a eu une baisse importante de la quantité de résidus miniers coulant à travers une brèche d'un bassin de rétention qui a contaminé les cours d'eau de la région de Cariboo.

Des millions de mètres cubes d'eaux usées et de limon ont coulé dans les lacs, les rivières et les ruisseaux des environs de la mine d'or et de cuivre Mount Polley, près du village de Likely, depuis lundi.

Le gouvernement a mentionné qu'Imperial Mines Corps (TSX:III), l'entreprise propriétaire du bassin de rétention, a construit des barrages temporaires afin de stopper la fuite.

Des douches publiques ont été livrées aux résidents de Likely, qui ont été affectés par une interdiction d'utilisation de l'eau qui a duré pendant plusieurs jours après l'accident.

L'interdiction a été partiellement levée, affectant la majorité de la ville et des secteurs de la rivière Quesnel.

L'avertissement est toujours en vigueur pour les communautés qui reçoivent leur eau du lac Polley, des ruisseaux Hazeltine et Cariboo ainsi que tous les secteurs du lac Quesnel.

Les tests initiaux du ministère provincial de l'Environnement laissent entendre que l'eau de certains secteurs de la région est potable.

The pond which stores toxic waste from the Mount Polley Mine had its dam break on Monday spilling its contents into the Hazeltine Creek causing a wide water-use ban in the area.\n\n (credit:Jonathan Hayward/The Canadian Press)
