October 28, 2025

NEWS RELEASE - DIEPPE, N.B., October 28, 2025 -- (CBI: TSX-V) Further to its news release of October 17, 2025, Colibri Resource Corporation (“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.

The upcoming program will focus primarily on the San Perfecto and Banco de Oro target areas—marking the first drilling by Colibri in these highly prospective zones. Drill targets have been defined through the integration of surface sampling, geological mapping, and geophysical surveys. The work has outlined multiple areas of coincident structural and geochemical signatures believed to represent extensions of known mineralized systems. The EP Gold Project lies within the prolific Caborca Gold Belt, host to numerous multi-million-ounce deposits and producing mines. “With gold prices at all-time highs and strong investor interest in quality exploration stories, we’re excited to be advancing the EP Gold Project with a fully funded program,” said Ian McGavney, President & CEO of Colibri. “We’re very pleased to be working with CANMEX, a proven operator in Sonora, as we look to build on the promising results already achieved at EP.”
