Colibri Resource Corporation Consolidates

Ownership of Diamante Project, Prepares for

Growth with Strategic Asset Realignment and

Share Consolidation

Dieppe, New Brunswick--(Newsfile Corp. - May 14, 2025) -

Colibri Resource Corporation

(TSXV:

CBI) ("Colibri" or the "Company") wishes to announce a series of strategic corporate developments

aimed at strengthening its asset base and capital structure. These include:

Increasing its effective ownership of the Diamante Gold-Silver Project in Sonora, Mexico

to 60%;

Entering an agreement to acquire its joint venture partner's remaining interest in the

project;

Monetizing a non-core asset through the sale of its 50% interest in the Jackie Project;

and

Implementing a share consolidation to position the Company for improved capital

markets access and long-term growth.

These actions align with Colibri's sharpened focus on advancing its two most advanced exploration

assets. The Company is collaborating with Tocvan Ventures on the potential future development of the

Pilar Gold & Silver Project, where drilling, bulk sampling and trenching suggest near-term production

potential. In parallel, Colibri is preparing for further advanced exploration activity at its 100%-owned EP

Gold Project, located in a multi-million-ounce gold corridor called the Caborca Gold Belt that hosts

Mexico's largest producing gold mine owned by Fresnillo Plc called La Herradura (25km west of EP).

The La Herradura, which has been operating since 1994, produced 367,000 ounces of gold in 2024 and

has 7.4 milllion ounces of gold remaining in reserves at the end of 2024 (source: Fresnillo Plc - 2024

Annual Report). Colibri geologists believe that EP shares key geological characteristics with nearby

gold deposits, including structure, lithology, and geochemistry-underscoring its discovery potential.

Colibri/Silver Spruce - Increases Ownership in Diamante Project to 60%

On May 10

th

, 2025, Colibri and its joint venture partner Silver Spruce Resources Inc. (TSXV: SSE)

("Silver Spruce") increased their joint ownership of the Diamante Project from 50% to 60%. This

increase is the result of an agreed to ownership dilution with its private Mexico based partner whereby

exploration activities carried out in 2024 - including diamond drilling and fieldwork - were funded entirely

by Yaque Minerales S.A. de C.V., a private Mexican company owned equally by Colibri and Silver

Spruce.

In recognition of this investment, Yaque Minerales will be issued an additional 10% ownership in Bimcol

Minera S.A. de C.V., the entity that holds 100% of the Diamante Project.

Colibri to Acquire Silver Spruce's Interest in Yaque Minerales

Following the earn-in, Colibri entered into an agreement on May 12, 2025 to acquire Silver Spruce's

50% ownership in Yaque Minerales, which will result in Colibri owning 100% of Yaque Minerales and,

thereby, an effective 60% interest in the Diamante Project. Colibri will accept ownership of Silver

Spruce's shares in Yaque in lieu of an approximately $80,000 of outstanding exploration expenditures

owing to Colibri, allowing Colibri to consolidate control of the project without equity dilution or additional

capital expenditure.

Ian McGavney, President & CEO of Colibri, stated:

"This series of transactions advances our strategic positioning for Colibri's future. First, by increasing

and consolidating our ownership of the Diamante Project, we are enhancing our exposure to a highly

prospective gold-silver asset in one of Mexico's most productive regions. Second, we've done so in a

non-dilutive manner. And third, this gives us flexibility to chart the Diamante's future with greater

control, which we believe will benefit shareholders."

Drill Exploration Highlights - Diamante Project

Colibri, through its partnership in Yaque Minerales, has completed two drilling campaigns on the

Diamante Gold-Silver Project since acquiring the option in 2021. These programs outlined a high-grade,

multi-target epithermal system hosted in veins, breccias, and shear zones typical of the Sierra Madre

mineral belt.

*Au and Ag equivalents were calculated using metal prices of US$1660 per ounce Au, US$18.65 per ounce Ag, US$1.32 per pound Zn, and

US$0.83 per pound Pb ; Lengths are intersection length.

True widths are not known.

The results confirm multiple high-grade mineralized centers across the Diamante concessions and

demonstrate excellent potential for discovery of new shoots and extensions. Many targets remain

untested by drilling and will be prioritized in future phases.

For more information about Diamante, please see our website:

The Diamante Gold & Silver Project is situated within the Sierra Madre volcanic sequence of Mexico

and lies within a district of epithermal mineralization in Sonora that hosts many producing and historic

gold, silver, and base metal mines including the La India Mine (Agnico Eagle), the Mulatos Mine (Alamos

Gold), and the Santana Mine (Minera Alamos).

Colibri Divests Interest in Jackie Project

In a related transaction, Colibri has agreed to sell its 50% interest in the Jackie Project, located in

Sonora, Mexico, to Silver Spruce. In exchange, Colibri will receive:

$25,000 worth of Silver Spruce shares, and

A 1% Net Smelter Return (NSR) royalty on any future production from the Jackie Project.

This transaction allows Colibri to monetize a non-core holding while maintaining future upside exposure

through the royalty.

Share Consolidation

The Company announces that, subject to approval of the TSX Venture Exchange (the "Exchange"), it

intends to complete a consolidation (the "Consolidation") of its common shares (the "Common Shares")

on the basis of five (5) pre-Consolidation Common Shares for one (1) post-Consolidation Common

Share (a "Consolidated Share").

Currently there are 115,417,625 Common Shares issued and outstanding. On a post-Consolidation

basis, the Company shall have approximately 23,083,525 Consolidation Shares issued and outstanding.

The CUSIP number of the Company will change. The Company's name and stock symbol will remain the

same after the Consolidation. No fractional Shares will be issued as a result of the Consolidation.

Instead, any fractional share interest of 0.5 or higher arising from the Consolidation will be rounded up to

one whole Consolidation Share and any fractional share interest of less than 0.5 will be cancelled.

The Company will issue a further news release notifying shareholders as to when the effective date of the

Consolidation will occur and the date on which the Company's Consolidated Shares will commence

trading on the Exchange.

Pursuant to the provisions of the

Business Corporations Act

(British Columbia) and the Articles of the

Company, the Consolidation will be approved by way of resolutions passed by the board of directors of

the Company but remains subject to the approval of the Exchange.

The Company believes that the Consolidation will enhance its ability to attract new investors, improve

trading liquidity, and support its broader strategic and financial initiatives.
