Our Commitment

For more than a decade, our goal has been to design a project with minimal impact, in partnership with the people of the Bristol Bay region, which meets Alaska's highest environmental standards. 

We, along with the world's leading scientists, have diligently studied the environment to best co-exist with the surrounding elements and have developed a new plan to share with you.


About the Deposit

The Pebble Deposit is what’s called a porphyry deposit. It’s one of the largest of its kind known in the world: primarily copper, with lesser amounts of molybdenum, gold, silver, and other trace metals.

Throughout the years, we’ve drilled more than 1 million feet of core samples from the rock, mapping the extent of the Deposit. Pebble is big, but its mineral content is diffuse — it’s not concentrated in veins and nuggets.

Where is Pebble?

Despite what you may have heard, Pebble is not at the headwaters of Bristol Bay. It is located at the upper reaches of three small tributaries — out of more than 50,000 in the Kvichak and Nushagak watersheds. 

You should know that we’ve spent more than $150 million and 10 years studying the environment surrounding the Deposit. As Alaskans ourselves, we care about the environment and are taking the time to design a modern mine with progressive management systems.

Our Core Values

The Pebble Partnership is dedicated to environmentally responsible resource development that respects cultural values and develops economic opportunities for Southwest Alaska.

  • Pebble will benefit Alaskans

  • Pebble will co-exist with healthy fish, wildlife and other natural resources

  • Pebble will apply the world’s best science

  • Pebble will help build sustainable communities

  • At Pebble, we listen before we act

About the Partnership

Based in Anchorage, Alaska, the Partnership is led by CEO Tom Collier, former U.S. Department of the Interior chief of staff during the Clinton administration. He holds extensive experience in navigating the federal environmental permitting process. Prior to joining the Partnership in 2014, Mr. Collier spent 40 years serving as a partner for the law firm Steptoe & Johnson in Washington, D.C. As a senior leader in environmental law and permitting, Mr. Collier has worked on Alaska related projects in his career including development of Alpine, CD-5, and the reauthorization of the Trans-Alaska Pipeline System.

In addition to engineering design and mine planning, the Pebble Partnership oversees a robust program of activities in the areas of mineral exploration, environmental/socioeconomic studies, stakeholder relations and public affairs. The partnership is owned by Northern Dynasty Minerals.
