The Pebble Project is seeking to develop a globally significant deposit of copper, gold, molybdenum and silver into a modern mining operation. It is located on land that the State of Alaska secured during the Cook Inlet Land Exchange of 1974 -- a three way land swap involving the federal government, the state and the Cook Inlet Region Inc. (CIRI), an Alaska native regional corporation. The State of Alaska secured land including what is now Pebble, explicitly for its mineral potential.
The Pebble deposit is one of the greatest stores of mineral wealth ever discovered. The current resource estimate includes 6.44 billion tonnes in the measured and indicated categories containing 57 billion lb copper, 70 million oz gold, 3.4 billion lb molybdenum and 344 million oz silver; and 4.46 billion tonnes in the inferred category, containing 24.5 billion lb copper, 37 million oz gold, 2.2 billion lb molybdenum and 170 million oz silver(1)
. Quantities of palladium and rhenium also occur in the deposit.
Key project strengths include:
(1) 2014 Pebble mineral resource estimate
- a mineral resource with the tonnes, grade, metallurgy and geometry to potentially support a modern, long-life mine;
- one of the most extensive environmental databases ever assembled for a resource development project in America;
- a stable and predictable regulatory environment in Alaska and the US; and
- broad public support for responsible resource development in Alaska.
