BUFFALO POTASH FILES ANNUAL INFORMATION FORM AND NEW TECHNICAL REPORT

Buffalo Potash Corp. has filed its annual information form (AIF) for the year ended Dec. 31, 2025, as well as a revised version of its technical report in respect of the Disley property entitled "NI 43-101 Preliminary Economic Assessment (PEA) Technical Report on the Disley Potash Project, Saskatchewan, Canada" prepared by Dr. Ryan Langdon, PhD, CGeol, Christopher Jacobs, CEng, MIMMM, and Richard Thompson, CEng, MIChemE, of Micon International Co. Ltd., Jack Nagy, PEng, of Nagy Process Consulting Inc., Jared Galenzoski, PGeo, FIMMM, of Fides Strategic Resource Management Ltd., Dr. Douglas F. Hambley, PEng, RM-SME, of DFH Geoscience & Engineering LLC, and Greg Vogelsang, PEng, PGeo, of Earthview Environmental Engineering Ltd. to supersede the company's technical report filed on April 27, 2026. The AIF and new technical report have been filed on SEDAR+ and are available under the company's profile.

The company has filed the new technical report to correct a typographical error in two tables in which certain figures were stated in the incorrect quantum -- expressed as thousands rather than the millions indicated by the unit label. The error was limited to those tables and had no effect on any underlying calculations, economic results, mineral resource estimates, production parameters or conclusions of the PEA. All other content of the new technical report remains unchanged. The company notes that the correct figures, expressed in millions of United States dollars, were accurately reported in its news release dated April 27, 2026, announcing the results of the PEA.
