COPPER-GOLD: EIS contractor hired for Pebble project

ALASKA – Vancouver-based Northern Dynasty says everything is moving forward at its Pebble copper-gold project 380 km from Anchorage. The U.S. Army Corps of Engineers approved the hiring of AECOM as an independent, third party contractor to work with the company to complete the environmental impact statement for the new mine.

With the contractor hired, the Corps is expected to begin a series of public meetings for what it calls the “scoping” stage. The formal consultation and public comment period will occur after the Pebble draft EIS is published, expected sometime in 2019.

Northern Dynasty puts the measured and indicated resource at 6.4 billion tonnes grading 0.41% copper and 0.34 g/t gold or a copper equivalent of 0.76%. The inferred resource is 4.5 billion tonnes grading 0.25% copper and 0.26 g/t gold for a copper equivalent of 0.54%. A cut-off of 0.3% copper equivalent was used.

The project economics are to be updated in 2018. Visit or  for more information.
