BUFFALO POTASH ANNOUNCES INITIATION OF MAIDEN RESOURCE ESTIMATE AND PRELIMINARY ECONOMIC ASSESSMENT FOR FLAGSHIP DISLEY PROJECT

Buffalo Potash Corp. has engaged Micon International Ltd., an independent mining consulting firm, to prepare a National Instrument 43-101-compliant mineral resource estimate and a preliminary economic assessment (PEA) for its flagship Disley project, located approximately 50 kilometres northwest of Regina, Sask.

Highlights:

• Buffalo Potash has engaged Micon International to prepare a mineral resource estimate and preliminary economic assessment, anticipated to be completed Q2 2026;
• Micon International has extensive experience in potash, with recent involvement in technical studies of potash development projects;
• Initiation of study follows Buffalo's recent and continuing technical programs, including 3-D seismic, reassaying of historic drill core and its 2026 drilling program at Disley.

Study overview

The company has engaged Micon to deliver a maiden resource estimate and PEA, with an anticipated completion date of Q2 2026. The appointment of Micon to deliver the mineral resource estimate and PEA is an important milestone for the Disley project as it will provide the first independent assessment of mineral inventory and preliminary project economics, which are expected to include estimates of cash flows, net present value (NPV), internal rate of return (IRR) and payback period.

Micon is a leader in mineral resource estimation and mining project advisory with extensive experience in estimating potash-mineralized systems, including recent involvement in mineral resource estimates and technical studies for potash development projects.

The mineral resource estimate and preliminary economic assessment are expected to support the company's modular horizontal line drive (HLD) strategy at the Disley project by establishing the geological and engineering basis for potential phased solution mining development and defining technical work programs to advance the project toward feasibility.

Steve Halabura, PGeo, chief executive officer of Buffalo, commented: "The Disley project possesses many of the defining characteristics of Saskatchewan's most successful solution potash mining operations, including potash mineralization observed in historical drilling, favourable depth, a strategic location in the heart of one of the world's premier potash-producing districts and access to existing infrastructure. Importantly, the Disley project was specifically targeted based on extensive historical geological and drilling data and we have since invested considerable time and private capital advancing the project prior to initiating our 2026 confirmation program."

Mr. Halabura added: "We believe the maiden resource and PEA will mark an inflection point for Buffalo, advancing Disley toward development and establishing a road map for a modular strategy that we believe can be scaled across Saskatchewan."

The Disley project

The Disley project is located approximately 50 kilometres northwest of Regina and covers 9,413 hectares. The property is situated immediately adjacent to the east of the K+S Bethune potash solution mine and north of the Mosaic Belle Plaine potash solution mine -- both of which are amongst the largest producing potash solution mines in the world. In the opinion of management, the Disley project is in one of the most favourable areas of Saskatchewan for potash solution mining as evidenced by the success of these neighbouring projects.

Cautionary statement regarding preliminary economic assessment

The PEA will be preliminary in nature and is intended to support the technical evaluation of the Disley project. The PEA will be based on the mineral resource estimate once completed, and there is no certainty that the results of the PEA will demonstrate economic viability or that the conclusions will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

Investor relations agreement

Buffalo is also pleased to announce it has entered into an agreement commencing Feb. 23, 2026, with Oak Hill Financial Inc., an arm's-length party to Buffalo, to provide certain investor relations services to Buffalo Potash, including, without limitation, in relation to providing strategic advice with respect to Buffalo's stakeholder communication initiatives and to expand market awareness.
