Current Status

In January 2021, the USFS published a Final Environmental Impact Statement (FEIS), but it was rescinded in March 2021 to allow for further review and tribal consultation. On April 17, 2025, the USFS issued a 60-day notice of its intent to republish the FEIS and Draft Record of Decision (DROD), marking an important step forward in the federal permitting process. During this time, Resolution Copper continues to consult and partner with local communities and Native American Tribes to guide the development of the project and the benefits it will deliver.

Once the Final EIS is republished and the Record of Decision (ROD) is released, the public has 45 days to object to the decision, and the USFS must respond and address any concerns within 90 days. Once this period is complete, and we receive a Final ROD and the USFS can issue a final approved plan of operations.

The Resolution Copper project can only move forward and eventually begin producing copper once the Final ROD is issued and all required federal, state, and local permits are obtained.
As we look to the future, copper is key to climate action and a low-carbon world. We believe we can make a positive contribution to this new world; not only by providing natural resources but also by delivering social benefits in terms of employment and economic opportunities and taking care to avoid or lessen impacts on the environment, culture, and heritage.
