Critical One Energy Announces Upsized CDN$6,875,000 Flow-Through Private Placement

Critical One Energy Inc. (CSE: CRTL) (OTCQB: MMTLF) (FSE: 4EF) is pleased to announce an upsize to the non-brokered private placement announced on July 21, 2026. Under the amended terms, the Company will now issue up to 6,250,000 flow-through common shares ("FT Shares") at a price of CDN$1.10 per FT Share for gross proceeds of up to CDN$6,875,000 (the "Offering"). The strong institutional support for this oversubscribed financing gives us the runway to keep drilling, follow up on the strong results from Phase I and advance the Howells Lake Antimony-Gold Project through to the end of 2027. It allows us to move the project forward from a position of financial strength," said Duane Parnham, Founder, Executive Chairman and CEO of Critical One. The Company may pay finder's fees on a portion of the Offering to eligible finders in the form of (i) a cash commission of up to 6.0% of the gross proceeds raised under the Offering, and (ii) common share purchase warrants of the Company ("Finder's Warrants") in an amount up to 6.0% of the FT Shares issued under the Offering. Each Finder's Warrant will be exercisable to purchase one common share in the capital of the Company at a price of CDN$1.65 per common share for a period of eighteen (18) months from the date of closing. The Company intends to use the gross proceeds from the sale of the FT Shares to incur exploration expenses that are eligible "Canadian exploration expenses" that qualify as "flow-through mining expenditures" as such terms are defined in the Income Tax Act (Canada). The Offering is scheduled to close in two tranches. The first tranche, of up to CDN$5,625,000, is expected to close on or around July 30, 2026. The second tranche, of up to CDN$1,250,000, is expected to close on or around August 14, 2026. All securities issued pursuant to the Offering described above will be subject to a four-month and one-day hold period.
