Northern Dynasty Minerals Ltd reported that the Final Environmental Impact Statement for its Pebble copper-gold-molybdenum project in southwest Alaska has been released by lead federal regulator, the US Army Corps of Engineers . The Final EIS describes a proposed open-pit mining operation and associated ore processing facilities in southwest Alaska, an 82-mile road, pipeline and utilities corridor to a permanent, year-round port facility on Cook Inlet, a lightering location in Iniskin Bay, a 164-mile natural gas pipeline from existing energy infrastructure on the Kenai Peninsula to the Pebble mine site, a 270 MW natural gas-fired power plant at the mine site and smaller power generation facility at the port site.

Over 20 years of mining, the Pebble Project as proposed will extract ~70 million tons of mineralized material annually at the extremely low strip ratio of just 0.12:1. A conventional blast-haul-crush and froth flotation milling process with nameplate capacity of 180,000 tons per day will be employed to produce, on average, 613,000 tons of copper-gold concentrate each year (containing 318 million lb Cu, 362,000 oz Au and 1.8 million oz Ag) and 15,000 tons of molybdenum concentrate (containing 14 million lb Mo).

Shortly following release of the Final EIS, the USACE is expected to issue a Record of Decision with respect to several of Pebble's key federal permits. The Pebble Partnership must also secure a number of permits issued by the State of Alaska, a process expected to take 2-3 years.

On the strength of the Final EIS and ROD expected this summer. Northern Dynasty's goal is to secure a major mining company or consortium of companies to become a partner in the Pebble enterprise, and participate in the final stages of project evaluation, design and permitting. In the meantime, the Pebble Partnership will continue to advance programs and partnerships to enhance public and political support for the Pebble Project in Alaska, and prepare for state permitting.
