BUFFALO POTASH ANNOUNCES INITIATION OF MAIDEN

RESOURCE ESTIMATE AND PRELIMINARY ECONOMIC

ASSESSMENT FOR FLAGSHIP DISLEY PROJECT

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; and

• Initiation of study follows Buffalo’s recent and ongoing technical programs, including 3D seismic,

re-assaying of historic drill core, and its 2026 drilling program at Disley.

SASKATOON, Saskatchewan, February 19, 2026 – Buffalo Potash Corporation (TSXV: BUFF) (the

“Company” or “Buffalo”) is pleased to announce that it has engaged Micon International Limited (“Micon”),

an independent mining consulting firm, to prepare a National Instrument 43 -101 (“NI 43 -101”) compliant

Mineral Resource Estimate (the “Mineral Resource Estimate”) and a Preliminary Economic Assessment

(the “ PEA”) for its flagship Disley Project (the “ Disley Project ”), located approximately 50 kilometres

northwest of Regina, Saskatchewan.

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 towards feasibility.

Mr. Steve Halabura P.Geo., Buffalo Chief Executive Officer, 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 district s, 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 a nd 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 roadmap for a modular strategy that we believe

can be scaled across Saskatchewan.”

The Disley Project

The Disley Project is located approximately 50km 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(1) – 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 favorable

areas of Saskatchewan for potash solution mining (see Figure 1) as evidenced by the success of these

neighboring projects(1)(2).

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 e conomic viability or that the conclusions will be realized.

Mineral resources that are not mineral reserves do not have demonstrated economic viability.

Notes

(1) The K+S Bethune potash solution mine and north of the Mosaic Belle Plaine potash solution mine

(together, the “Adjacent Properties”) may each be considered an “adjacent property” (within the meaning

of NI 43-101) to the Company’s Disley Project. The Company does not have any interest in either of the

Adjacent Properties. The Company believes this context is useful in illustrating the proven endowment of

the district, while noting that mineralization on adjacent or nearby properties is not indicative of

mineralization on the Company’s Disley Project. There is no guarantee that the Disley Project will yield

comparable results to either of these mines.

(2) No mineral resources , as categorized by NI 43 -101, have been defined on the Disley Project. The

Company will need to conduct additional work to define mineral resources. There is no guarantee that the

Company will be able to define mineral resources as categorized by NI 43-101 on its Disley Project.
