Name and Location
Pebble copper/gold/molybdenum project, Alaska, US.

Client
The Pebble Limited Partnership (PLP), which comprises Northern Dynasty Minerals (NDM).

Project Description
The project proposes to construct a large openpit mine; an on-site milling facility; on-site storage for rock, ore and tailings; a port facility; an access road connecting the mine site to the port; an on-site water supply for the mill; and to provide electrical power for the mine site, in south-west Alaska.

In addition, the project plans to include an on-site 378 MW gas-fired turbine plant, a 138 km transportation corridor to Cook Inlet for road and pipeline rights of way and a new deep-water port at Cook Inlet.

The project’s key assets are the near-surface 4.1-billion-tonne openpit-style Pebble West deposit and the deeper and higher-grade 3.4-billion-tonne Pebble East deposit, which is amenable to underground bulk mining methods. The Pebble resources rank among the world’s most important accumulations of copper, gold and molybdenum.

Estimates show that the Pebble deposit comprises measured and indicated resources of 5.94-billion tonnes, grading 0.78% copper equivalent, and containing 55-billion pounds of copper, 67-million ounces of gold and 3.3-billlion pounds of molybdenum.

The deposit also has 4.84-billion tonnes of inferred resources, grading 0.53% copper equivalent and containing 26-billion pounds of copper, 40-million ounces of gold and 2.3-billion pounds of molybdenum.

Value
Capital expenditure on Pebble will reach between $6-billion and $8-billion.

Duration
Commercial production is expected by 2015.
