MILLENNIAL POTASH CORP. INITIATES DEFINITIVE FEASIBILITY STUDY WITH US DFC FUNDING AT ITS BANIO POTASH PROJECT, GABON

Millennial Potash Corp. has initiated a definitive feasibility study (DFS) at its Banio potash project in Gabon. The company has engaged Ercosplan Ingenieurgesellschaft Geotechnik und Bergbau mbH, a preeminent global potash specialist consulting company with significant experience in the West African potash basin, to complete an AACE Class 3 definitive feasibility study for the Banio potash project.

Farhad Abasov, Millennial's chair, commented: "We are very pleased to have initiated a definitive feasibility study at Banio after completion of our recent mineral resource estimate which yielded measured plus indicated mineral resources totalling 2,453 billion tonnes grading 16.6 per cent KCl, and inferred resource totalling 3,559 billion tonnes also grading 15.6 per cent KCl. The launch of the feasibility study and recently initiated ESIA mark the transition from the exploration to the development stage. We look forward to working with Ercosplan as we continue to develop the Banio potash project in preparation for our mining licence application. The company is fully funded to complete the DFS and all associated tradeoff studies in partnership with U.S. International Development Finance Corp. which has committed $3-million (U.S.) to cover the feasibility study costs."

Additional details regarding the mineral resource estimate referenced above can be found in the company's news releases dated Dec. 29, 2025, and Nov. 17, 2025.

The DFS will evaluate a solution mining operation with a base production scenario of 800,000 tonnes per year (tpy) as well as significantly larger production rates of Muriate of Potash (MOP). Several technical and trade-off studies are currently in progress including dissolution tests, hydrogeological studies, creep tests, cold versus hot leaching evaluations, port options for the project, as well as high-purity salt marketing studies. The DFS will run in parallel to the company's recently announced ESIA as both are expected to be completed in H2 2026 and will be presented to the government of Gabon as part of the company's application for a mining licence. The company will continue with further drilling as well.

The information in this news release has been reviewed and approved by Peter J. MacLean, PhD, PGeo, director of the company, who is a qualified person as that term is defined in National Instrument 43-101.

We seek Safe Harbor.
