Mr. Steve Halabura P.Geo., Chief Executive Officer of the Company, commented: "The strong demand for this financing, and the enthusiasm from both new and existing investors, is a clear endorsement of our strategy and the quality of the Disley Project. With a strengthened balance sheet, we are well positioned to advance toward first production through our capital-efficient Initial Production Module — a defining step toward developing a generational asset in the world's premier jurisdiction for potash production." Mr. Halabura continued: "With a clear line of sight on the milestones ahead, our team is focused on disciplined execution and on proving out our modular development strategy, which we see as the next evolution of global potash production.

At a time when securing long-term fertilizer supply has become a global priority, we believe the future of food security starts now — and Buffalo Potash intends to be part of it."

The FT Shares are priced at C$0.52 per share and the Charity FT Units at C$0.558 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) (the " Tax Act "), and each Charity FT Unit consists of one such flow-through Share and one-half of one Warrant.

Each whole Warrant is 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 further advance geological potential and fund the downhole infrastructure buildout of the Initial Production Module (" IPM ") at the Disley Project located in Saskatchewan.
