Colibri Provides Update on Diamante Project

Acquisition and Jackie Project Disposition

Dieppe, New Brunswick--(Newsfile Corp. - June 15, 2026) - Colibri Resource Corporation (TSXV: CBI)

(the "Company") wishes to provide the following updates regarding its acquisition of an additional 10%

in its Diamante project to 60% and the disposition of its 50% interest in the Jackie project to Silver

Spruce Resources Inc. (see the Company's news release dated May 12, 2025).

Diamante Project

As previously disclosed on May 12, 2025, the Company and SSE entered into an agreement whereby

SSE will transfer its 50% ownership in Yaque Minerals Inc. ("Yaque") to the Company in exchange for the

forgiveness of $80,000 of outstanding exploration expenditures owed to the Company by SSE. The

transaction will result in the Company owning 100% of Yaque and an effective 60% interest in the

Diamante Project.

As there is a common director between the Company and SSE (Kevin O'Connor), the

transaction is deemed to be non-arm's length under TSX Venture Exchange rules (the "Exchange") and

is therefore subject to Exchange approval. The transaction, however, is not subject to Multilateral

Instrument 61-101 or TSXV Policy 5.9 and as such, minority shareholder approval or valuation

requirements are not required.

The acquisition will result in Colibri holding 60% interest in the Diamante Project. The transaction

simplifies the ownership structure, provides the Company with greater flexibility in managing its

investment in Diamante, and eliminates the need to coordinate future decisions through a joint venture

ownership arrangement. Management believes the transaction represents an attractive opportunity to

increase the Company's exposure to a highly prospective gold-silver project without share dilution or

additional cash consideration.

Since earning its initial interest in the Diamante Project, Colibri and its partners have completed drilling,

geophysical surveys, geological mapping and geochemical sampling programs that have identified

multiple mineralized targets and expanded the project's exploration potential. The Company remains

encouraged by the exploration results generated to date and believes Diamante continues to represent

a valuable component of its Mexican precious metals portfolio.

Jackie Property

As previously disclosed, on May 12, 2025, the Company and SSE entered into an agreement whereby

the Company agreed to sell its 50% interest in the Jackie Property to SSE in exchange for $25,000 of

shares of SSE and a 1% Net Smelter Return royalty on any future production from the Jackie Project.

The agreement was amended on November 12, 20225 whereby it was confirmed that SSE would be

issuing 166,667 common shares to the Company. As there is a common director between the Company

and SSE (Kevin O'Connor), the transaction is deemed to be non-arm's length and is therefore subject to

Exchange approval. The transaction, however, is not subject to Multilateral Instrument 61-101 or TSXV

Policy 5.9 and as such, minority shareholder approval or valuation requirements are not required. SSE

has already obtained conditional approval from the Exchange (see SSE's news release dated June 5,

2026).

The disposition of the Company's 50% interest in the Jackie Project is consistent with management's

strategy of focusing capital and technical resources on its core assets, including the EP Gold Project, the

Pilar Gold & Silver Project and the Diamante Project. The Company also retains a 1% Net Smelter

Return royalty on the Jackie Project, preserving exposure to potential future project success.

Kevin O'Connor, the common director of the Company and SSE, has abstained from voting on both

transactions.
