Pebble Gold Copper Project

The Pebble deposit is a copper-gold deposit about 15 miles northwest of the villages of Iliamna and Newhalen, in the foothills of the Mulchatna River drainage. It is located within the Lake & Peninsula Borough boundaries, on state-owned land, and situated within a 55,800 acre mining claims block.

The right to develop the Pebble deposit is owned by Northern Dynasty Minerals, Inc. (NDM) which is a subsidiary of the Canadian company Hunter Dickinson. NDM is proposing to construct an open pit mine and milling operation to produce gold, copper, molybdenum, and silver.

The deposit is estimated to contain 26.5 million ounces of gold and 16.5 billion pounds of copper with lesser amounts of molybdenum and silver. According to these estimates, the deposit ranks as the largest gold deposit in North America and the second largest deposit of copper.

If the mine is developed, it would become both North America's and Alaska's largest open pit mine and one of the largest mines in the world. Current assessments recommend that the optimum amount of ore that should be milled per day range from 90,000 to 200,000 tons over the life of the mine, which is estimated from 30 to 60 years.Mining experts anticipate it will take 8 to 12 years to construct or develop the mine.

The project is in the pre-EIS stage of development, and NDM is collecting baseline environment and socio-economic information to use when it applies for permits to begin constructing the mining operation.
