COLIBRI ANNOUNCES EFFECTIVE DATE OF SHARE CONSOLIDATION

Further to Colibri Resource Corp.'s press release on May 14, 2025, Colibri has received approval of the TSX Venture Exchange for the consolidation of its issued and outstanding common shares on the basis of five preconsolidation shares for each one postconsolidation share.

The consolidation is being effected pursuant to a resolution of the board of directors of the company dated May 5, 2025. No shareholder approval is required for the consolidation to come into effect. The company has obtained a new Cusip (194168407) and ISIN (CA194168407) in connection with the consolidation. There will be no name change or trading symbol change in conjunction with the consolidation.

Effective at the opening of trading on Friday, June 13, 2025, the shares will commence trading on the TSX-V on a consolidated basis.

As at the date hereof, there are a total of 115,417,625 shares issued and outstanding. Assuming no other change to the issued and outstanding shares, a total of 23,083,525 shares, subject to adjustments for rounding, will be issued and outstanding on the effective date.

No fractional postconsolidation shares will be issued as a result of the consolidation. Fractional shares will be rounded up to the next nearest whole number of shares if the fraction is at least half of a share and rounded down to the nearest whole number of shares if the fraction is less than half a share.

The exercise or conversion price, and the number of shares issuable under any of the company's outstanding convertible securities, if any, will be proportionately adjusted upon the effective date.

A letter of transmittal from the company's transfer agent, Computershare Investor Services Inc., will be mailed to registered shareholders providing instructions on how to exchange their physical share certificates representing preconsolidation shares for new certificates representing postconsolidation shares.

Shareholders who hold their shares in DRS/Book or in brokerage accounts are not required to take action to effect an exchange of their preconsolidation shares for postconsolidation shares. Until surrendered, each share certificate representing preconsolidation shares will represent the number of whole postconsolidation shares to which the holder is entitled as a result of the consolidation.
