West Vancouver, British Columbia - Newsfile Corp. - November 17, 2025 - Millennial Potash Corp. (TSXV: MLP) (OTCQB: MLPNF) (FSE: X0D) ("MLP", "Millennial" or the "Company") is pleased to announce the results of an updated Mineral Resource Estimate ("MRE") for the northern part of its Banio Potash Project in Gabon. The MRE has an Effective Date of Nov. 11, 2025 and was completed by ERCOSPLAN Ingenieurgesellschaft Geotechnik und Bergbau mbH ("ERCOSPLAN"), one of the oldest and best-known potash specialist consulting companies in the world with significant experience in the West African Potash Basin.

Farhad Abasov, Millennial's Chair, commented, "Millennial Potash is delighted to report that its updated Mineral Resource Estimates (MRE) for the northern part of its Banio Potash Project has exceeded all our expectations marking a major milestone in our development. Last year we had no Measured Resource, whereas now we have 648M tonnes of maiden Measured Resource. The total Measured and Indicated Resource increased by 275% while the Inferred Resource went up by 210%. The increase in resources since our maiden resource in 2024 has been massive with Carnallitite Measured + Indicated resources of 2.42B tonnes at 15.5-% KCl and additional Inferred Carnallitite resources of 3.6B tonnes also grading 15.4% KCl. This vast increase in the resources calculated may also allow us to consider substantially expanding any planned production scale in the future. The newly calculated resources underscore the project's immense potential, as it covers only about 5% of the entire project area. The presence of sylvinite seams constitute a higher-grade resource that adds further promise to the Project. It is important to note that the resources cover only a fraction of the northern part of the entire Project area and based on historical drill results and seismic work we believe the Project deposit continues both to the south and to the north. With significant thicknesses of potash mineralization encountered in all drillholes to date, locally in excess of 100m, we see support for our interpretation that these potash seams have thickness, grade and continuity making them potentially highly suitable to solution mining. Moving forward this MRE is expected to provide a solid base for a Feasibility Study ("FS") which is being supported by the U.S. International Development Finance Corp. ("DFC") by a non-dilutive USD $3M in funding. The FS will investigate various possible production scenarios via solution mining." The MRE includes Measured Carnallitite Mineral Resources of approximately 648 million tonnes grading 15.7% KCl, Indicated Carnallitite Mineral Resources of approximately 1.769 billion tonnes grading 15.4% KCl, Indicated Sylvinite Mineral Resources of 35 million tonnes grading 24.3% KCl, Inferred Carnallitite Mineral Resources of 3.463 billion tonnes grading 15.4% KCl, and Inferred Sylvinite Mineral Resources of 96.2 million tonnes grading 24.2% KCl (see Tables 1,3,4,5). The MRE includes analytical results from the 2024 MRE for holes BA-002 and BA-003, plus 2025 drilling results from the extension of BA-001 (BA-001-EXT), and new hole BA-004. (see MLP Press releases dated Sept. 16, 2025 and Oct. 14, 2025). The 2025 MRE values equate to approximately 102 million tonnes of contained KCl in the Measured category, about 281 million tonnes of contained KCl in the Indicated category and approximately 555 million tonnes of contained KCl in the Inferred category (see Tables 3, 4 and 5) In addition, compared to 2024 MRE, MLP has added a large maiden Measured Mineral Resource of 648 million tonnes at 15.7% KCl (see MLP Press release dated Jan. 16, 2024). The Banio Potash Project is located at the north end of the West-African Evaporite Basin. This is a well-established potash basin. The Mineral Resource Estimate for MLP's Banio Potash Project is comprised of Measured, Indicated and Inferred resources based on the definition of potash-bearing seams or beds in numerous sedimentary evaporite cycles or stages that were identified from drill core collected from potash specific exploration drillholes. The Mineral Resources are comprised of carnallitite and sylvinite resources as detailed in Tables 3, 4 and 5. Geological Model The geological model of Banio Potash mineralization identifies 7 potash-bearing Evaporite Cycles (CII to CVIII) with up to 20 seams of carnallitite and 3 seams of sylvinite in individual Cycles. For the potash seams to be considered as potentially suitable for solution mining, which is deemed to be the optimal mining method to sustain a low-cost economic operation at Banio, they must meet certain thickness and grade...
