Beaver Dam Mine Project

Atlantic Mining NS Inc., a wholly owned subsidiary of St Barbara Limited, is proposing the construction, operation and reclamation of an open pit gold mine in Marinette, Nova Scotia. The Beaver Dam Mine Project would have an ore production rate of 2.1 million tonnes/year, over a five-year period. Ore from the Project would be crushed and transported 31 kilometres by road to the Touquoy Mine for processing. Components of the Project would include an open pit, mine haul roads, waste material storage piles (non-acid generating, potential acid generating, topsoil, till and organics), run-of-mine and low-grade ore stockpiles, crusher, operational facilities, and water management. The Project would rely on the Touquoy Mine site for the processing of ore and storage of tailings in the exhausted Touquoy Pit.
