The Final Environmental Impact Statement

For more than a decade, our goal has been to design a project with minimal impact. The Final Environmental Impact Statement (EIS), published in July 2020, demonstrates that the Deposit can be responsibly developed. The EIS is a transparent, science-driven, and objective technical regulatory review.

  • Led by the U.S. Army Corps of Engineers

  • 11 cooperating government entities

  • 35 participating Bristol Bay & Cook Inlet Tribal Governments

  • 15 years of independent scientific research and analysis

  • $150 million in environmental studies


Conclusion: The Fish Habitat Is Protected

Given the vast breadth and diversity of habitat, impacts are not likely to be noticeable (EIS 4.24-47).

The Water is Safe

Everything depends on clean water, from fish to people to wildlife. According to the EIS, there would be no effects on any community groundwater or surface water supplies from the changes in groundwater flows at the mine site (EIS 67).

The Fisheries are Safe

The EIS states that the Project would not affect the health of the Bristol Bay salmon fishery, including permit holder earnings, permit value, crew earnings, wholesale values, processor earnings, or local fiscal contributions (4.6-18). Overall, impacts to fish and wildlife would not be expected to impact harvest levels (ES-35).
