Northisle Copper and Gold (TSX: NCX) has released an updated preliminary economic assessment (PEA) on a 22-year, 75,000 t/d open pit development within its North Island project at the north end of Vancouver Island in BC.

According to the release, the latest study “confirms that the North Island project is one of the most attractive copper-gold porphyry projects in Canada.” The project would mine the Red Dog and Hushamu deposits at North Island and produce a copper concentrate with gold by-products as well as a molybdenum concentrate.
