Manitou Goldex project:
An innovative partnership to rehabilitate the abandoned Manitou mine site
The Manitou-Goldex project is the first of its kind in terms of rehabilitation. The Manitou site will be rehabilitated by covering its tailings with mine tailings from Agnico-Eagle Mines’ Goldex Mine. The tailings from the Goldex mine are cyanide- and sulphide-free and have good neutralization potential.
The project consists of building a pipeline between the Goldex mine and the abandoned Manitou site to transport the Goldex mine tailings. The cost of the project has been estimated at $47 million; it will be carried out over a period of 12 years.
Resulting from more than a year’s worth of discussions and negotiations, this government-industry partnership has many advantages and is perfectly consistent with sustainable development principles. It represents an estimated savings of $12 million for the government and helps to reduce the long-term management costs of industry tailings. It also substantially reduces the area disrupted by mining activity by avoiding construction of a large tailings impoundment near Val-d’Or. In addition, it will require the use of fewer natural resources (sand-gravel-clay) than building a new tailings impoundment and rehabilitating the Manitou site.
A framework agreement was signed by the partners—the Ministère des Ressources naturelles et de la Faune, Agnico-Eagle Mines Ltd. and the Ministère du Développement durable, de l’Environnement et des Parcs—when the project was announced by Minister Pierre Corbeil and industry representatives on November 28, 2006, in Val-d'Or.
Work on the Manitou site began in January 2007.
