Colin Joudrie, President & CEO, commented: "Creating a modern, cost-effective, and environmentally responsible option to ship Selkirk Copper's high value copper-gold-silver concentrate to the global market is a critical part of our mine restart strategy. Working with the Municipality and Port of Skagway over the past year, to create a detailed assessment of the options available for shipping critical mineral concentrates to market, that meet the needs and expectations of the community and the operational requirements of the Port of Skagway, has been time well spent."
