Northern Dynasty Issues Correction

November 22, 2023 Vancouver – Northern Dynasty Minerals Ltd. (TSX: NDM; NYSE American: NAK) (" Northern

Dynasty") reports that in a Crux Investor interview dated September 19, 2023, Northern Dynasty CEO Ron Thiessen

discussed the level of engineering conducted over the past two decades on the Pebble Project and may have left

the impression that the level of study is at a higher level t han that currently defined by its September 18, 2023

Preliminary Economic Assessment Technical Report. These statements about the Pebble project may be

potentially misleading. Northern Dynasty re-affirms that the September 18, 2023 report properly reflects the level

of study and retracts the pertinent statements made in the September 19, 2023 interview. Investors should not

rely upon these statements. Further, the September 18, 2023 Technical Report includes the use of inferred

mineral resources that ar e considered too geologically speculative to have the economic considerations applied

to them that would enable them to be categorized as mineral reserves.
