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% (the " Upsize Option ") described in its news release dated June 22, 2026, increasing the maximum size of the Offering to C$14,850,000.

Under the Second Tranche, the Company issued 1,500,000 Charity Flow-Through Units (" Charity FT Units ") at a price of C$0.558 per Charity FT Unit for gross proceeds of C$837,000.00. 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 (the " Hard Dollar Units "), 6,994,073 common shares of the Company (a " Share ") on a "flow-through" basis (the " FT Shares "), and 16,273,056 Charity FT Units for total aggregate gross proceeds of C$14,850,001.96.

Mr. Steve Halabura P.Geo., 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 online in early 2027." As previously announced, the Hard Dollar Units are priced at C$0.45 per unit and each consists of one Share and one-half of one common share purchase warrant (each whole warrant, a " Warrant "). 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.
