Sirios Resources Inc. Closes Fully-Subscribed $25 Million Brokered LIFE Offering of Flow-Through Units and Units

Sirios Resources Inc. (TSXV: SOI) (OTCQB: SIREF) (the "Company") is pleased to announce that it has closed its previously announced "best efforts" private placement offering under the LIFE Exemption (as defined herein) of: (i) 40,740,740 flow-through units of the Company (each, a "FT Unit") at a price of $0.27 per FT Unit (the "FT Offering"), and (ii) 70,000,000 units of the Company (each, an "HD Unit" and together with the FT Units, the "Units") at a price of $0.20 per HD Unit (together with the FT Offering, the "Offering"), which includes the full exercise of the option granted to the Agents (as defined herein), for aggregate gross proceeds to the Company of approximately $25,000,000.

Each FT Unit consists of one common share of the Company (each, a "FT Share") and one-half of one common share purchase warrant of the Company (each whole common share purchase warrant, a "FT Warrant"). The FT Shares and FT Warrants comprising the FT Units each qualify as "flow-through shares" within the meaning of subsection 66(15) of the Income Tax Act (Canada) (the "ITA").

Each HD Unit consists of one common share of the Company and one-half of one common share purchase warrant of the Company (together with the FT Warrants, the "Warrants").

Each Warrant entitles the holder thereof to purchase one non-flow-through common share of the Company (each, a "Warrant Share") at a price of $0.30 per Warrant Share, subject to customary anti-dilution adjustments, at any time on or before March 18, 2027, subject to acceleration in certain circumstances.

The Offering was completed pursuant to the terms of an agency agreement dated March 18, 2026 among the Company, National Bank Capital Markets, and MDCP Securities Ltd. (together, the "Agents"), as co-bookrunners and co-lead agents. As consideration for their services in connection with the Offering, the Company paid the Agents a cash commission equal to $1,212,499.99.

The Units were issued in reliance on the "listed issuer financing exemption" available under Part 5A of National Instrument 45-106 - Prospectus Exemptions, as amended by Coordinated Blanket Order 45-935 - Exemptions from Certain Conditions of the Listed Issuer Financing Exemption (the "LIFE Exemption") in each of the provinces and territories of Canada. Pursuant to the LIFE Exemption, all Units sold to purchasers resident in Canada in connection with the Offering are not subject to resale restrictions in Canada in accordance with applicable Canadian securities legislation. The Units were also offered in jurisdictions outside of Canada on a private placement or equivalent basis, in each case in accordance with all applicable laws, provided that no prospectus, registration statement or other similar document is required to be filed in such jurisdiction. The Offering remains subject to final acceptance by the TSX Venture Exchange (the "Exchange").

The Company will use an amount equal to the gross proceeds received by the Company from the sale of the FT Units, pursuant to the ITA, to incur (or be deemed to incur) eligible "Canadian exploration expenses" that qualify as "flow-through mining expenditures" (as both terms are defined in the ITA and proposed amendments thereto) (the "Qualifying Expenditures") related to the Company's projects in Canada as more fully described in the Company's amended and restated offering document dated March 16, 2026, on or before December 31, 2027, and will renounce all the Qualifying Expenditures in favour of the initial subscribers of the FT Units effective on or prior to December 31, 2026. In the event the Company is unable to renounce the Qualifying Expenditures effective on or prior to December 31, 2026 for each FT Unit purchased in an aggregate amount not less than the gross proceeds raised from the issue of the FT Units or the Qualifying Expenditures are otherwise reduced by the Canada Revenue Agency, the Company will (to the extent permitted by the ITA) indemnify each initial subscriber of the FT Units for any additional taxes payable by such subscriber as a result of the Company's failure to renounce the Qualifying Expenditures or as a result of the reduction as agreed.

The net proceeds from the sale of HD Units will be used to incur additional Canadian exploration expenses and for general corporate and administrative expenses and working capital purposes.
