Resolution Copper welcomes next phase in public review and comment

Superior, Ariz. (January 15, 2021) – Resolution Copper welcomes the next phase of public review and comment with the release by the US Forest Service (USFS) of its Final Environmental Impact Statement (EIS) for the Resolution Copper Project.

“The Final EIS is an important step in the ongoing permitting process, reflecting years of extensive community engagement and rigorous, independent study by the US Forest Service to shape the design plan. We are still years away from any decision to invest in developing this project, that could eventually supply up to one-quarter of the nation’s copper demand, bringing jobs and lasting economic benefits to Arizona and supporting America’s clean energy future,” said Resolution Copper Project Director Andrew Lye.

“We are committed to ongoing engagement with Native American Tribes and working to seek consent before any decision on the development of the project, consistent with the International Council on Mining and Metals (ICMM) Statement on Indigenous Peoples and Mining.”

As the lead agency charged with overseeing the federal approval process mandated by the National Environmental Policy Act (NEPA), the USFS has spent more than seven years studying the potential impacts of the project and collecting feedback from local stakeholders. With assistance from dozens of county, state and federal cooperating and consulting agencies, as well as 11 local Native American Tribes and community leaders, third-party experts from the USFS considered more than 30,000 public comments, which were submitted in response to the Draft EIS that was published in August 2019.

Several significant changes were made to the project design in response to community feedback. Notably:

  • The permanent protection of the culturally significant natural feature of Apache Leap
  • A Tribal Monitor program focused on cultural heritage protection
  • A partnership to protect and conserve culturally significant Emory Oak groves across Arizona
  • Economic and community development agreements that can deliver significant long-term benefits for the Superior community

Through the NEPA process, dozens of alternatives to the original mine plan proposal, including different tailings locations and technologies, as well as alternative mining methods, were independently analyzed. The Final EIS also outlines mitigation measures to future potential impacts involving noise, lighting, visual, traffic, housing, socioeconomics, air, surface water, groundwater, water quantity, water quality, land, cultural resources, tribal values, and more.

To date, more than $2 billion has been spent to develop and permit the project, including reclamation of the historic Magma Copper Mine site, sinking a second shaft to mining depth, rehabilitating an existing shaft and deepening to mining depth, extensive drilling and ore body testing, and the federal approval and public engagement process.

Resolution Copper is poised to supply up to one-quarter of the nation’s copper demand, a critical step toward delivering a low-carbon future. The project has the potential to create approximately 3,700 direct and indirect jobs in Arizona. Overall, the project could bring $61 billion in additional economic value to Arizona over the estimated 60-year life of the mine, creating lasting benefits for the region and playing a vital role in the nation’s economic recovery.

The Final EIS is now subject to 45 days of further public review and comment before the USFS can issue a final record of decision, which is expected in the second half of 2021. The USFS’s full process schedule and other detailed information on the NEPA process is available at The EIS  publication triggers a land exchange approved by Congress under the Obama administration in 2014, whereby 5,459 acres of high-value conservation land will be transferred to the Federal Government in return for Resolution Copper taking ownership of approximately 2,422 acres around the mining site.

After the USFS process, further permitting will be progressed with other authorities and a detailed feasibility study completed over several years to inform investment considerations on the project. When an investment decision is made, Resolution Copper is expected to take around 10 years building infrastructure to prepare for the commencement of mining.
