Northern Dynasty Makes Annual Filings

Northern Dynasty Minerals Ltd. (TSX:NDM)(NYSE American:NAK) ("Northern Dynasty" or the "Company") and 100%-owned U.S.-based subsidiary Pebble Limited Partnership ("Pebble Partnership" or "PLP") have filed a motion for leave to file an amended complaint in the federal district court in Alaska to reverse the U.S. Army Corps ("USACE") decision to deny the project a permit

Ron Thiessen, President and CEO of Northern Dynasty, said "It is important to understand that this is not a new lawsuit. It is simply an amendment of the complaint we filed against the Environmental Protection Agency ("EPA") by adding the USACE as another defendant. We think this substantially strengthens the existing case by focusing directly on the permit denial which was an underlying reason for the EPA veto."

Northern Dynasty Minerals Ltd. (TSX:NDM);(NYSE American:NAK) ("Northern Dynasty" or the "Company") and 100%-owned U.S.- based subsidiary Pebble Limited Partnership ("Pebble Partnership" or "PLP") have been advised by the US Army Corps of Engineers ("USACE") that, after months of successive delays, the USACE has declined to engage in the remand process related to the November 25, 2020 denial of a permit application for the Pebble Project, citing the U.S. Environmental Protection Agency's ("EPA") intervening veto of the development at Pebble

After the November 25, 2020, denial of the permit application for the Pebble Project, a separate division of the USACE remanded the denial decision back to the USACE Alaska District on April 25, 2023, after an administrative review found numerous errors with the denial decision. Today, after several requests for extensions, the USACE has announced that it has declined to engage in the remand process altogether. The USACE reasoning is due to the EPA veto, which effectively prevents them from altering their decision while that veto is in place. On March 15, 2024, we announced we were filing an appeal of the EPA veto in Federal District Court in Alaska, and the State of Alaska filed its action against the veto on April 11, 2024.

(TSX:NDM)(NYSE American:NAK) ("Northern Dynasty" or the "Company") and 100%-owned U.S.-based subsidiary Pebble Limited Partnership ("Pebble Partnership" or "PLP") note that on April 11, 2024 the State of Alaska ("the State") filed an action in Federal District Court in Alaska, seeking to vacate the Environmental Protection Agency's ("EPA") veto of a development at Pebble

Northern Dynasty Minerals Ltd. (TSX:NDM)(NYSE American:NAK) ("Northern Dynasty" or the "Company") and 100%-owned U.S.-based subsidiary Pebble Limited Partnership ("Pebble Partnership" or "PLP") is filing two separate actions in the federal courts challenging the federal government's actions to prevent the companies from building a mine at the Pebble Project

Action Seeks to overturn EPA's illegal veto

Northern Dynasty Minerals Ltd. (TSX:NDM)(NYSE American:NAK) ("Northern Dynasty" or the "Company") provides additional commentary on the recent United States Supreme Court ("Supreme Court") decision to not allow Alaska to bypass the typical court review process as it works to overturn the Environmental Protection Agency's ("EPA") illegal veto of the Pebble Project lands and comments on anticipated next steps

Decision is Purely Procedural
It is important to note that this decision is purely procedural and does NOT imply whether the Supreme Court agrees or disagrees with the merits of the case. Alaska was pursuing a narrow exception to the usual requirement that cases first be heard by a federal district court and a federal circuit court of appeals before being considered by the Supreme Court. Based on their decision, the next logical step is to proceed with a filing in the federal district court.
