Preliminary Economic Assessment Pebble Project Completed

VANCOUVER, - Northern Dynasty Minerals Ltd. has filed the "Preliminary Economic Assessment NI 43-101 Technical Report, Pebble Project, Alaska" (2021 PEA). The 2021 PEA also examines three potential mine expansion scenarios, each with a mine life that could reach more than 100 years, and potential scenarios for gold recovery that could form the basis for future permit applications and review. The Project could potentially provide more than $8 billion to the Southwest Alaska region through the Pebble Performance Dividend and the Lake and Peninsula Borough severance tax over the life of the potential expansion scenarios. This is in addition to the benefits that could flow from the existing and possible future agreements with Alaska Native Village Corporations.

"The 2021 PEA forecasts strong economics for the Proposed Project and also demonstrates significant optionality for future potential developments," said Northern Dynasty President and CEO Ron Thiessen. "We have made a significant investment in the design of this project to ensure it can be built and operated with industry-leading environmental safeguards while generating significant financial returns over multiple decades. It has never been about the Pebble Mine Project or the Bristol Bay Fishery; it has always been about the Bristol Bay Fishery and the Pebble Mine Project. We look forward to more engagement, in the near future, on the expansive and financially rewarding opportunities for the communities and the residents of Western Alaska resulting from a potential Pebble Mine development."
