BUFFALO POTASH MOBILIZES DRILL RIG FOR INITIAL

PRODUCTION MODULE DEVELOPMENT

Highlights

• Successful assembly of diverse technical team for Initial Production Module development;

• Site preparation at the Initial Production Module drilling site is complete;

• All well licenses received for full drill program at Initial Production Module drilling site; and

• Rig mobilization at Initial Production Module drilling site commencing imminently.

SASKATOON, Saskatchewan, July 14, 2026 – Buffalo Potash Corporation (TSXV: BUFF) (OTCQB:

BLPTF) (FRA: VU5) (the “Company” or “Buffalo”) is pleased to announce the initiation of the next phase

of work at the Initial Production Module ("IPM") at the Company's flagship Disley property in Saskatchewan

(the "Disley Project"), located adjacent to two of Canada's currently producing potash solution mines (see

Figure 2), the K+S Bethune Solution Potash Mine and the Mosaic Belle Plaine Solution Potash Mine.(1)

Initial work includes the drilling of two vertical wells to further confirm the Company's geological

understanding at the IPM site. These wells are expected to be later converted into a source well , for brine

collection, and a disposal well , for brine disposal, as part of the IPM design (the " Source Well " and

"Disposal Well", respectively).

Mr. Quinton Hardage , P.Eng., PMP, President and Chief Operating Officer of the Company,

commented: "Buffalo has assembled a team of technical professionals with firsthand experience in potash

solution mining, directional drilling, geomechanics, and dissolution chemistry within Saskatchewan's

geology, and we have full confidence in their ability to execute. With well licenses in hand, contracts signed,

and rig mobilization set to begin, we are thrilled to move forward with our plans to become Cana da's next

potash producer."

Mr. Quinton Hardage continued: "In our view, the initiation of the Initial Production Module brings us one

step closer to demonstrating Buffalo's patented Horizontal Line-Drive methodology at scale. Each stage of

the IPM development program is designed to systematically reduce technical risk while advancing Buffalo

toward initial commercial production and the concurrent feasibility study for the broader Disley Project. This

is about more than sustainability – it's about proving that potash can be produced with greater capital

efficiency and true scalability, potentially changing the way the industry recovers this critical mineral moving

forward."

Disley Project Development Plan

The IPM is designed to produce 125,000 tonnes per annum (“TPA”) of soluble-grade potash and is the first

of three planned solution mining facilities at the Disley Project . The IPM has a lower initial CAPEX

requirement compared to the full Disley Project build -out and is targeted to reach first production in Q1

2027. At full build-out comprising the IPM and two 500,000 TPA mines ("Disley East" and "Disley West"),

the Disley Project would be expected to produce up to 1,125,000 TPA of potash, as contemplated in

Buffalo's recently released preliminary economic assessment titled “NI 43 -101 Preliminary Economic

Assessment Technical Report on the Disley Potash Project, Saskatchewan, Canada” dated May 21, 2026,

and effective April 15, 2026 (the “PEA”), a copy of which is available on the Company’s SEDAR+ profile at

www.sedarplus.ca. On a standalone basis, the PEA attributes a payback period of approximately 12 months

from the start of IPM production.(2) However, there is no guarantee that the Company will be able to achieve

production.

The Company's production decision for the IPM is not based on a feasibility study of mineral reserves

demonstrating economic and technical viability, and such production decisions are historically associated

with a higher risk of economic and technical failure (see "Note 3 – Production Decision Cautionary

Statement").

The IPM is designed for the Company to establish initial cash -flowing production at lower upfront capital

cost, while building the operational and technical foundation for full-scale development. Development of the

IPM is anticipated to be broken down into five phases:

1. Source and disposal wells;

2. Horizontal Line-Drive ("HLD") drilling;

3. Brine circulation;

4. Site development; and

5. Surface processing.

Disley Project Updates

Technical Team Assembled – Buffalo has fully assembled the technical team that is expected to advance

construction of the IPM. The team has been purpose-built for the task, bringing together a diverse range of

disciplines with Saskatchewan -specific expertise in dissolution chemistry, potash geology, directional

drilling, geomechanics, and solution mining operations – including individuals with firsthand experience

developing and operating potash solution mining wells within the same geological setting as the Disley

Project.

Site Preparation – Site preparation at the IPM drilling site location is complete (see Figure 1) , including

stripping and stockpiling of topsoil and subsoil to prepare a stable, level surface for safe and effective rig

mobilization and drilling operations.

Well Licenses Received – Buffalo has received all well licenses for wells required for IPM construction,

including for the Source Well and Disposal Well, which represent the first steps of IPM construction before

the drilling of horizontal wells. As outlined in the Company’s July 6, 2026 news release, the Source Well is

anticipated to produce brackish water from the Mannville Formation, which will then be saturated with NaCl

to form the solvent used in Buffalo’s solution mining method, while the Disposal Well will be used to dispose

of ex cess brine into the Deadwood Formation after processing at surface. In addition to their ongoing

operational roles at the IPM, both wells will be cored and logged through the potash -bearing members of

the Prairie Evaporite Formation, providing data that will inform the concurrent feasibility study and provide

further clarity on the full build-out of the Disley Project.

Rig Mobilization – Contracts for the work program have been executed with the Company's drilling

contractors, and mobilization of the drilling rig to the Source Well location is expected to commence

imminently, with drilling anticipated to begin shortly after rig-up is complete. The Source Well is the first of

two vertical wells to be drilled at the IPM and is anticipated to be followed by the Disposal Well. Each well

is expected to be drilled and, upon reaching target depth, cored and logged through the potash -bearing

members.

Disley Project - General Overview

The Disley Project is located approximately 50 kilometers northwest of Regina and covers 10,610 hectares

(Crown and Freehold mineral rights). The property is situated immediately 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 among

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 Figu re 2) as

evidenced by the success of these neighboring operations.(1)

On May 22, 2026, Buffalo released the results of its maiden NI 43-101 Mineral Resource Estimate and PEA

for the Disley Project, prepared by Micon International Co Limited. The PEA outlined a phased, modular

development plan contemplating full -scale product ion of up to 1,125,000 TPA of potash across three

solution mining facilities, with an estimated after-tax net present value (NPV) of US$1.1B at a discount rate

of 8% and estimated internal rate of return (IRR) of 30%. (2) Readers are encouraged to refer to Buffalo's

April 27, 2026 and May 22, 2026 news releases and the NI 43 -101 technical report filed on SEDAR+ for

complete details of the PEA and Mineral Resource Estimate.

Notes

(1) The K+S Bethune potash solution mine and 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 has no 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 C ompany’s

Disley Project. There is no guarantee that the Disley Project will yield comparable results to either of these

mines.

(2) The PEA was prepared by Micon International Co Limited in accordance with National Instrument 43 -

101 Standards of Disclosure for Mineral Projects and is preliminary in nature. The PEA includes inferred

mineral resources, which are considered too speculative geologically to have the modifying factors and

economic considerations applied to them that would enable them to be categorized as mineral rese rves.

Mineral resources that are not mineral reserves do not have demonstrated economic viability. There is no

certainty that the results of the PEA will be realized. Readers are encouraged to read the technical report

filed under the Company's profile on SEDAR+ at www.sedarplus.ca in its entirety, including all

qualifications, assumptions, and exclusions that relate to the PEA.

(3) Production Decision Cautionary Statement : The Company's decision to proceed with development of

the IPM is not based on a feasibility study of mineral reserves demonstrating economic and technical

viability. No mineral reserves have been established at the Disley Project, and the PEA is prelimin ary in

nature (see Note 2). Historically, mineral projects advanced to production without first establishing mineral

reserves supported by a feasibility study have a higher risk of economic and technical failure. Specific risks

associated with the Company's production decision include, without limitation: that the grade, continuity, or

thickness of mineralization differs from the Mineral Resource Estimate; that the Company's Horizontal Line-

Drive mining method, which has not been operated at commercial scale, does not perform as anticipated;

that recoveries, production rates, or capital and operating costs differ materially from the PEA; and that the

IPM does not achieve sustained or profitable production, which would materially and adversely affect the

Company's ability to generate revenue and cash flow.
