Dieppe, New Brunswick--(Newsfile Corp. - October 28, 2025) - Further to its news release of October 17, 2025, Colibri Resource Corporation (TSXV: CBI) ("Colibri" or the "Company") is very pleased to announce that, due to continued strong investor demand, it has increased the size of its previously announced unit offering (the "Unit Offering") from 8,333,333 units to 10,000,000 units at a price of $0.15 per unit (a "Unit") for gross proceeds of approximately $1,500,000. To accommodate the increased interest, the Company will be closing the offering in two tranches with the first tranche expected to close by the end of October and the second tranche by mid-November.

Each Unit is comprised of one (1) common share and one (1) common share purchase warrant. Each warrant will entitle the holder to acquire an additional common share of the Company at a price of C$0.25 for a period of 24 months.

Insiders of the Company may acquire securities in the Unit Offering. Any participation by insiders will constitute a "related party transaction" as defined under Multilateral Instrument 61-101 Protection of Minority Security Holders in Special Transactions ("MI 61-101"). The Company expects such participation will be exempt from the formal valuation and minority shareholder approval requirements of MI 61-101 as the fair market value of the securities subscribed for by insiders, nor the consideration paid, is expected to exceed 25% of the Company's market capitalization.

Securities issued in accordance with the Unit Offering will be subject to a statutory four-month-and-one-day hold period. The Company may pay finder's fees in accordance with TSX Venture Exchange policies. The Unit Offering is subject to approval by the TSX Venture Exchange.
