Warwick Smith, CEO of American Pacific stated:

"The Plan sets a clear path forward for the next five years, outlining the additional work programs necessary for gathering pre-feasibility level data and ensuring a thorough and assessment of the Project. The submission of the Plan also marks a significant milestone and a pivotal step forward, reaffirming our commitment to responsible resource development."

Peter Mercer, VP of Advanced Projects for American Pacific, stated:

"Safeguarding the environment is one of our top priorities and part of our commitment to responsible stewardship of the Project. The comprehensive program outlined in the Plan will continue to significantly bolster our understanding of the natural environment within the Project area, establishing a crucial baseline for the environmental conditions.

About the Palmer Project

The Palmer Project is an advanced-stage high-grade volcanogenic massive sulphide project located within the Porcupine Mining District of the Haines Borough, Alaska. The Project is operated in a joint venture partnership between American Pacific, through its wholly owned subsidiary, Constantine North Inc. as the manager (operator) Dowa.

As of December 31, 2023, over US$100 million had been invested in exploration and development work and environmental programs to responsibly advance the Project. The Palmer Project hosts a National Instrument 43-101 mineral resource of 4.68 million tonnes of 10.2% zinc equivalent (3.9% copper equivalent) in the indicated category and 9.59 million tonnes of 8.9% zinc equivalent (3.4% copper equivalent) in the inferred category. Please refer to the Company's Preliminary Economic Assessment ("PEA"), which was completed in June 2019 (filed July 18, 2019, amended March 7, 2022; filed on ).

The amended PEA is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that amended PEA results will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
