Upper Beaver Gold Project

Agnico Eagle Mines Limited is proposing the construction, operation, decommissioning and abandonment of an underground and open-pit gold and copper mine located 20 kilometres northeast of Kirkland Lake, in Ontario. As proposed, the Upper Beaver Gold Project includes an on-site metal mill and structures for diverting water. The maximum ore production capacity of the mine is 15,000 tonnes per day, and the maximum ore input capacity of the metal mill is approximately 10,000 tonnes per day, with a mine life of about 16 years. The project would require the diversion of over 90 million cubic metres of water per year from Beaverhouse Lake downstream to the Misema River.
