  Vancouver, British Columbia – TheNewswire - 27 May, 2026 – Avventura Resources Ltd. (CSE:AA) (Avventura or the Company) is pleased to provide an update on additional assay results from the Company’s 2025 prospecting and rock sampling program completed on the Horwood Property located southwest of Timmins Ontario. Highlights Multiple anomalous and locally high-grade gold grab samples identified across the Horwood Property.   Highest newly reported grab sample returned 24.0 g/t Au.   Additional grab samples returned 21.9 g/t Au, 7.94 g/t Au, 2.80 g/t Au, 1.46 g/t Au, 1.13 g/t Au and 1.02 g/t Au.   Numerous additional anomalous gold values identified across the broader sampling program.   The broader 2025 prospecting program has now returned grab samples grading up to 62.0 g/t Au.   Areas of anomalous soil sampling results coincident with areas of high-grade rock samples continue to support the exploration potential and merit of the Horwood Property and warrant additional follow-up work.     Avventura CEO, Sean Flynn, commented , “We are encouraged by the continued results from the exploration program at Horwood. While the property remains at an early stage of exploration, the identification of multiple anomalous and locally high-grade gold samples across several areas of the property continues to support management’s belief that Horwood warrants additional exploration.

These results, combined with the previously announced 62.0 g/t gold sample, provide further evidence of widespread gold prospectivity across the project.”    Rock Sample Results   The reported rock grab samples were collected from multiple target areas and historical occurrence zones across the Horwood Property, including areas surrounding the Denross occurrence and other prospective geological
