BUFFALO POTASH ANNOUNCES CLOSING OF SECOND AND FINAL TRANCHE OF OVERSUBSCRIBED AND UPSIZED C$14.85 MILLION NON-BROKERED PRIVATE PLACEMENT

Further to the news releases dated June 8, 2026, June 9, 2026, June 22, 2026, and June 24, 2026, Buffalo Potash Corp. has closed the second and final tranche of its oversubscribed and upsized non-brokered private placement, thereby completing the offering. As previously announced, in response to strong investor demand, the company exercised in full the option to increase the size of the offering by up to 10 per cent described in its news release dated June 22, 2026, increasing the maximum size of the offering to $14.85-million. Together with the first tranche of the offering that closed on June 24, 2026, the company has raised aggregate gross proceeds of $14,850,001.96 under the offering through the issuance of an aggregate of 28,006,504 securities.

Under the second tranche, the company issued 1.5 million charity flow-through units at a price of 55.8 cents per charity FT unit for gross proceeds of $837,000. The closing of the second tranche completes the offering. Across both the first tranche and the second tranche, the company issued an aggregate of 4,739,375 hard dollar units, 6,994,073 common shares of the company on a flow-through basis and 16,273,056 charity FT units for total aggregate gross proceeds of $14,850,001.96.

Steve Halabura, PGeo, chief executive officer of the company, commented: "The conventional approach to building new potash supply -- enormous upfront capital, decade-long timelines and the budget escalations that have come to define large greenfield development -- is reaching its limits, and the industry knows it. We believe that creates an opening for a smarter model, and we believe Buffalo Potash is positioned to deliver it. With this oversubscribed financing now fully closed, we have the financial strength to turn our focus to operational execution and excellence as we advance toward becoming the next major supplier of global potash. Our goal is to reshape the future of global supply with a mining methodology that draws on techniques used every day in the oil and gas sector to deliver production that is more sustainable, more capital efficient and more scalable than what the industry is used to. This begins with our capital-efficient initial production module, which we are targeting to bring on-line in early 2027."

As previously announced, the hard dollar units are priced at 45 cents per unit, and each consists of one share and one-half of one common share purchase warrant. The FT shares are priced at 52 cents per share and the charity FT units at 55.8 cents per unit. Each FT share consists of one share that qualifies as a flow-through share within the meaning of the Income Tax Act (Canada), and each charity FT unit consists of one such flow-through share and one-half of one warrant. Each whole warrant is exercisable at 60 cents 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 TSX Venture Exchange is at least 90 cents for 10 consecutive trading days.

The company will use the gross proceeds from the FT shares and charity FT units to further advance geological potential and finance the downhole infrastructure buildout of the initial production module 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 company has received conditional approval from the TSX Venture Exchange for the offering. 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 Dec. 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 Dec. 31, 2026. An amount equal to the gross proceeds from the charity FT units will be used to incur, on or before Dec. 31, 2026, eligible Canadian development 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 charity FT units with an effective date no later than Dec. 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-per-cent upfront deduction to the purchasers of charity FT units.

In connection with the second tranche, the company paid aggregate cash finders' fees of $40,500 and issued 90,000 non-transferable finders' warrants, on the same terms as the warrants, to eligible finders in accordance with applicable securities laws and the policies of the TSX-V.

No insiders of the company participated in the second tranche. The closing of the second tranche did not result in the creation of any new insiders or control persons of the company.
