BUFFALO POTASH ANNOUNCES NON-BROKERED PRIVATE PLACEMENT OF A

MINIMUM OF C$5,000,000

SASKATOON, Saskatchewan, June 8, 2026 – Buffalo Potash Corporation (TSXV: BUFF )

(OTCQB: BLPTF) (the “Company”) is pleased to announce a non-brokered private placement of

a minimum of C$5,000,000 in aggregate gross proceeds (the “Offering”). The Offering will consist

of any combination of (i) hard dollar units (the “ Hard Dollar Units”), (ii) flow-through shares (the

“FT Shares”), and (iii) charity flow -through units (the “ Charity FT Units ” and, together with the

Hard Dollar Units and FT Shares, the “ Securities”), with the allocation among each to be

determined by the Company in its sole discretion based on investor elections at the time of

closing.

The Hard Dollar Units will be priced at C$0.45 per unit and will each consist of one common share

of the Company (a “ Share”) and one-half of one common share purchase warrant (each whole

warrant, a “Warrant”). The FT Shares will be priced at C$0.52 per share and the Charity FT Units

at C$0.558 per unit. Each FT Share will consist of one Share that qualifies as a “flow -through

share” within the meaning of the Income Tax Act (Canada) (the “Tax Act”), and each Charity FT

Unit will consist of one such flow-through Share and one-half of one Warrant. Each whole Warrant

will be exercisable at C$0.60 to acquire one common share of the Company for 24 months from

issuance. The Company may accelerate the expiry of the Warrants on 30 days’ notice if the

volume-weighted average trading price of the Shares on the TSXV is at least C$0.90 for 10

consecutive trading days.

The Company will use the gross proceeds from the FT Shares and Charity FT Units to fund

downhole infrastructure buildout of the Initial Production Module (“ IPM”) at the Disley Project

located in Saskatchewan. The net proceeds from the Hard Dollar Units will be used for general

working capital and corporate purposes. The initial closing of the Offering is expected to occur on

or about June 30, 2026, and the Offering may close in one or more tranches . The Offering is

subject to certain conditions, including t he approval of the TSX Venture Exchange (“ TSXV”). All

securities will be subject to a statutory hold period of four months and one day.

An amount equal to the gross proceeds from the FT Shares will be used to incur, on or before

December 31, 2027, eligible “Canadian exploration expenses” (as defined in the Tax Act) on the

Disley Project, and such expenses will be renounced on a pro rata basis to each subscriber for

FT Shares with an effective date no later than December 31, 2026. An amount equal to the gross

proceeds from the Charity FT Units will be used to incur, on or before December 31, 2026, eligible

“Canadian development expenses” (as defined in the Tax Act) on the Disley Project, and such

expenses will be renounced on a pr o rata basis to each subscriber for Charity FT Units with an

effective date no later than December 31, 2026. Canadian development expenses will be

renounced on a declining balance basis in accordance with the Tax Act, and will not result in a

100% upfront deduction to the purchasers of Charity FT Units.

The Company may, subject to the approval of the TSXV, pay finder’s fees in connection with the

Offering, which may include the payment of cash and/or the issuance of warrants. Certain insiders

of the Company may participate in the Offering. The participation of any insiders may be

considered a “related party transaction” within the meaning of Multilateral Instrument 61 -101 –

Protection of Minority Security Holders in Special Transactions (“MI 61 -101”). The Company

expects that such participation will be exempt from the formal valuation and minority shareholder

approval requirements of MI 61-101. Further details of insider participation, if any, will be provided

in a subsequent material change report to be filed by the Company. The Securities are expected

to be eligible for RRSPs, RESPs, RRIFs, RDSPs, DPSPs, FHSAs and TFSAs.
