COPPER-GOLD: Independent review likes design of Western Copper’s Casino tails facility



YUKON – Vancouver-based Western Copper and Gold Corp. says that the independent engineering review panel that examined the general design of the Casino copper-gold project tailings management facility has confirmed the concept.

The engineering panel reviewed the proposed TMF design, assessed potential alternative storage technologies, and alternate locations. The team of experts confirmed that the design concept currently forming the basis of Western Copper’s submission to the Yukon environmental board represents the best available technology for storing solid waste from the Casino project. It also provided guidance and made recommendations to enhance the design of the TMF and to meet internationally accepted standards and good practices.

The panel included Peter Lighthall, Luis Valenzuela, Jim Obermeyer and Stephen Day as advisor.

The Casino project is based on a porphyry copper-gold-molybdenum deposit 300 km northwest of Whitehorse. A conventional open pit with flotation mill and a gold heap leach are expected to carry a pre-production capital cost of US$2.46 billion. Production could begin from the heap leach two years after final permits are received. Completion and start-up of the mill would take an additional two years.
