Pebble Mine’s watersheds

A 450 mile trek through the river systems downstream of the proposed mine site.

A thunderstorm approaches as we look over the mine site


Pebble Mine site


The Pebble Mine proposal

Largest open pit mine in North America – with additional large underground component.

Hundreds of billions of dollars of gold and copper ore.

Claim owned by Northern Dynasty Minerals – a Canadian company.

Haven’t yet filed for permits.

Land owned by the state of Alaska.

At the headwaters of two of the world’s largest salmon rivers.

Packrafting the Mulchatna River


Northern Dynasty has spent over $100 million already on exploration and studies.

The Pebble deposit is estimated to contain over 100 million ounces of gold and 90 billion pounds of copper, worth over $300 billion at today’s prices.


Unlike oil and gas production, mining operates under antiquated laws that give less than 2% of mineral values back to state and local government.

Proposed Pebble Mine Dams

  • 740 feet high
  • 4.3 miles long
  • Earth and rocks
  • Three Gorges Dam
  • 610 feet high
  • 1.24 miles long
  • Concrete

Frying Pan Lake, in the potential tailings lake area


Packrafts on the Nushagak River

In 2006, Nushagak River salmon runs totaled 18 million fish


Heavy Metals


Sulfuric Acid

46 million salmon

Bristol Bay

We made a commitment to stay out of Upper Talarik Creek because it is sensitive fish habitat." -Ella Ede, Northern Dynasty, July 2005

Pit plan overlaps the creek headwaters

Northern Dynasty applied for water rights to remove all the water from Upper Talarik headwaters for mine operation. – July 2006


“As Canadian citizens and residents certain of Northern Dynasty’s directors and officers may not subject themselves to U.S. legal proceedings, so that recovery on judgements issued by U.S. courts may be difficult or impossible.”

Descending to Upper Talarik Creek

  • Northern Dynasty’s claims:
  • We’ll stay out of Upper Talarik Creek
  • No Fish in Frying Pan Lake
  • No Cyanide

The mine would require a 100 mile road and slurry line to a port on Cook Inlet.

It would probably get power from a line across Cook Inlet to the Kenai Peninsula, but the mine’s power use would be more than currently used by the whole Peninsula.

Road near Iliamna village


Over 70% of gold produced is used to create jewelry.

  • On average one gold ring creates over 20 tons of tailings and other mine waste.
  • Gold and other commodities are often touted as “safe” investments in troubled times.
  • These investments lead to an increase in mining, simply to store the metals in vaults.

Thunderstorm over Pebble Valley

  • Don’t buy gold jewelry
  • Don’t invest in metals
  • Buy Wild Alaskan salmon
  • Comment on the BLM’s draft plan for the region
  • Visit Bristol Bay
  • Tell people
