Mr. Ronald Thiessen reports

NORTHERN DYNASTY ISSUES CORRECTION

In a Crux Investor interview dated Sept. 19, 2023, Northern Dynasty Minerals Ltd. chief executive officer 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 than that currently defined by its Sept. 18, 2023, preliminary economic assessment technical report. These statements about the Pebble project may be potentially misleading. Northern Dynasty reaffirms that the Sept. 18, 2023, report properly reflects the level of study and retracts the pertinent statements made in the Sept. 19, 2023, interview. Investors should not rely upon these statements. Further, the Sept. 18, 2023, technical report includes the use of inferred mineral resources that are considered too geologically speculative to have the economic considerations applied to them that would enable them to be categorized as mineral reserves.
