Pebble Project
Project Description
The Pebble Project is a copper-gold-molybdenum porphyry deposit in the advanced exploration stage of development. The project is located on state land in the Bristol Bay Region of southwest Alaska, approximately 17 miles northwest of the community of Iliamna.
The Project consists of two contiguous deposits. Pebble West is a near surface resource of approximately 4.1 billion metric tons. Pebble East is significantly deeper than Pebble West and contains an estimated resource at 3.4 billion metric tons.
Advanced exploration, concurrent reclamation, care and maintenance, and field sampling and monitoring activities are on-going.

The Pebble Project Technical Working Groups (TWGs) were created to facilitate pre-application state and federal agency discussions with the project proponent, Pebble Limited Partnership (PLP). TWG meetings began in mid-2007 and covered a wide array of topics as seen in the meeting minutes below. This voluntary process regarding environmental and project design studies was suspended by PLP in January 2010; communications between the PLP and individual agencies then continued through conventional channels and procedures.
Pebble Project Technical Working Group (TWG) Steering Committee
The Pebble Project TWG Steering Committee is composed of the primary leads from participating state and federal agencies. The TWG Steering Committee, and Pebble Limited Partnership (PLP) as applicant, will convene on at least a quarterly basis initially, and then as frequently as appropriate. It's role will be to guide the scope of the Technical Working Groups (TWGs) and coordinate TWG assignments to prevent overlap and/or study review gaps that could occur between TWGs, and to address issues or concerns raised by TWG leaders or groups. TWGs will not function as a consensus or decision-making authority.
The minutes below reflect discussion of suggestions and concerns raised by individuals during TWG meetings. Discussion does not reflect any decision-making or consensus from the group (with the exception of choosing a lead).
