NEWS RELEASE - DIEPPE, N.B., March 13, 2026 -- Colibri Resource Corporation (“Colibri” or the “Company”) (CBI: TSX-V) is pleased to report assay results from its maiden Phase 1 reconnaissance reverse circulation (“RC”) drill program completed at the Plomo claims within the Company’s 100% owned EP Gold Project located in the prolific Caborca Gold Belt of Sonora, Mexico, a region that hosts several significant gold deposits and mining operations including La Herradura and Noche Buena, which are operated by Fresnillo plc.  The Phase 1 program comprised 22 RC drill holes completed across the San Perfecto (20 holes) and Banco de Oro (2 holes) targets within the Plomo claim block, along with one RC drill hole completed at the West Sahuaro target located within the Evelyn claim block of the EP Gold Project. The program represents the first modern drill testing of multiple targets identified through geological mapping, geophysical interpretation and surface sampling across the Plomo claims. Highlights 7.5 m grading 2.92 g/t Au from 6 m, including 1.5 m grading 9.95 g/t Au (PL26-017) 30.0 m grading 0.73 g/t Au from 3 m, including 1.5 m grading 7.51 g/t Au (PL26-015) 30.0 m grading 0.45 g/t Au from surface, including 6 m grading 1.16 g/t Au (PL25-011) 19.5 m grading 0.44 g/t Au from 3 m, including 4.5 m grading 1.29 g/t Au (PL25-004) 1.5 m grading 12.55 g/t Au from surface (PL25-005) Gold mineralization intersected in 18 of 22 holes drilled in the Phase 1 program Gold mineralization intersected across an interpreted ~1.2 km mineralized structural corridor at the San Perfecto target Ian McGavney, President and CEO of Colibri Resource Corporation, commented : “We are extremely pleased with the results from our maiden drill program at the Plomo claims. Intersecting gold mineralization in 18 of 22 holes, including 7.5 metres grading 2.92 g/t gold and 30.0 metres grading 0.73 g/t gold from near surface, represents a strong start and provides compelling evidence of a broad mineralized system along the San Perfecto corridor. In addition, the results from Banco de Oro, where drilling intersected 30 metres grading 0.45 g/t gold including higher-grade intervals, further demonstrate the potential for multiple mineralized zones within the Plomo claim block. Together with the encouraging results from West Sahuaro, these results continue to strengthen our belief that the EP Gold Project hosts one or more significant gold system within the Caborca Gold Belt.” Table 1 – Significant Gold Intercepts – Plomo (0.10 g/t Au cutoff, maximum 3 m internal dilution; intervals are downhole lengths)

NEWS RELEASE - DIEPPE, N.B., January 15, 2026 -- Colibri Resource Corporation (“Colibri” or the “Company”) (CBI: TSX-V) is pleased to announce that it has resumed reverse circulation (“RC”) drilling in the Plomo area of its 100%-owned EP Gold Project in Sonora, Mexico. The current phase of work is designed to systematically evaluate priority structures and targets identified within the Plomo area, which has seen limited historical drilling, using a disciplined, first-pass exploration approach. Prior to the year-end break, the Company completed an initial phase of drilling at the San Perfecto and Banco de Oro targets consisting of eleven (11) RC drill holes totaling approximately 906 metres, with samples submitted for assay in December. The resumed program continues the first-pass evaluation of the San Perfecto target, while expanding testing to additional priority targets identified within the Plomo area. The Company plans to complete an additional six (6) to ten (10) RC drill holes as part of this phase of work. The Plomo area hosts multiple exploration targets within the broader EP Gold Project and has experienced minimal historical drilling. Colibri’s ongoing work at Plomo is part of a systematic, staged exploration strategy aimed at evaluating multiple targets across the area through a reverse circulation (RC) drilling program at the EP Gold Project. Samples from the Company’s December drilling campaign are currently at the laboratory. Based on current laboratory guidance, the Company anticipates that assay results from these initial drill holes may begin to be received in early February, subject to laboratory turnaround times. Results will be reported once received, compiled, and reviewed. “This phase of work represents a disciplined continuation of our first-pass exploration strategy at Plomo,” said Ian McGavney, President & CEO of Colibri Resource Corporation. “Our focus remains on systematically evaluating priority targets through careful execution and data collection, while maintaining operational momentum as we await results from the initial drill program.”

NEWS RELEASE - DIEPPE, N.B., December 17, 2025 -- Colibri Resource Corporation (“Colibri” or the “Company”) (CBI: TSX-V) is pleased to provide an update on its ongoing reverse circulation (“RC”) drilling program at the San Perfecto target within the Company’s 100%-owned EP Gold Project, located in the Caborca Gold Belt, Sonora, Mexico. Since mobilization, the Company has completed eleven (11) RC drill holes totaling approximately 906 metres at the San Perfecto and Banco de Oro targets. Drilling is continuing as planned, with crews focused on systematically advancing the current phase of the program. Samples from completed drill holes are currently being prepared for submission to an independent laboratory. Subject to laboratory turnaround times, initial assay results from the first holes are anticipated in January. Regional Mining Activity The State of Sonora hosts a concentration of producing and advanced-stage gold projects operated by several established precious metals companies. Mining and development activities in Sonora include projects operated by Fresnillo plc (La Herradura and Noche Buena mines), Alamos Gold (Mulatos Mine and Mulatos District), Agnico Eagle Mines (La India Project), Osisko Development (San Antonio Project), Minera Alamos (Santana Mine and Cerro de Oro Project), and Aztec Minerals (Cervantes Project), among others. These projects are cited for regional context only and illustrate Sonora’s long-standing role as one of Mexico’s most active and infrastructure-supported mining jurisdictions. San Perfecto Target – Drilling Progress  The San Perfecto target represents one of several priority exploration areas identified within the EP Gold Project. Current drilling activities are focused on methodically advancing the target area while maintaining steady operational momentum early in the program.
