Dieppe, New Brunswick--(Newsfile Corp. - January 28, 2025) - Colibri Resource Corporation (TSXV: CBI) ("Colibri" or the "Company") is pleased to share an update with its shareholders and interested parties in regard to its up to 1,250 metre diamond drilling program presently underway at its jointly held El Pilar Gold & Silver Project in Sonora Mexico. Colibri holds 49% interest of the El Pilar along side its partner Tocvan Ventures, which holds 51% ownership.

Drilling Update

Six holes have now been completed totalling 672.2 metres and a seventh hole is presently underway. Cores from the first several holes have been logged and are presently being prepared to be shipped for geochemical analysis. The Company will report results in due course upon review of the data.

On January 22^nd, 2025, Tocvan Ventures reported the following in regard to the first four diamond drill holes completed in our 2025 program at Pilar: "The aim of the core program is to build out a more robust geological model across the area. Each hole completed has successfully intersected lithologies and structures (vein zones, breccia zones and/or large fault gouges) known to host and control gold - silver mineralization at Pilar that will aid in modelling. The Company cautions these are visual indications; assay results are pending to verify the grade of mineralization."

Ian McGavney, President & CEO of Colibri states, "The Company is excited to move forward with its partner Tocvan Ventures to unlock Pilar's significant potential. The new data derived from this diamond core drilling program will be added to the project's geological model as well as to an upcoming Maiden Resource Estimate. We look forward to updating our shareholders on these drill results and our other progress at Pilar as we move towards our goal of being a near term gold & silver producer."

About the Pilar property

The Pilar gold-silver property has returned some of the region's best drill results. Coupled with encouraging gold and silver recovery results from metallurgical test work, Pilar is primed to be a potential near-term producer. The project is interpreted as a structurally controlled low-sulphidation epithermal system hosted in andesite rock. Initially, three primary zones of mineralization were identified on the original property from historic surface work and drilling, and are referred to as the Main zone, North Hill and 4-T. Each trend remains open to the southeast and north, and new parallel zones have been discovered. Structural features and zones of mineralization within the structures follow an overall northwest-southeast trend of mineralization. Mineralization extends along a 1.2-kilometre trend. Only half of that trend has been drill tested so far.
