GoldHaven Resources Corp. announced the completion of its fifth diamond drill hole (CO-05) at the Copecal Project, located in Mato Grosso State, Brazil. Hole CO-05 represents the first test of the Western Target, following the successful completion of four holes at the Eastern Target.
Highlights: Fifth drill hole (CO-05), completed -- first test of the Western Target at the Copecal project, Mato Grosso, Brazil. 140 metres drilled intersecting a thick saprolite horizon (50 m vertical) underlain by sheared basement gneiss and muscovite schist, confirming structural continuity across the property.eneath the saprolite, drilling encountered competent bedrock composed of strongly sheared basement gneiss & muscovite schist -- lithologies consistent with those intersected in previous holes -- further supporting the interpretation of structural continuity across the project area. The Company plans to complete an additional three holes as part of the ongoing reconnaissance drill program at Copecal.
This phase is designed to systematically test anomalous gold-in-soil and coincident very-low-frequency (VLF) electromagnetic anomalies previously reported. The program aims to refine the understanding of subsurface geology, alteration, and the structural controls on mineralization across both the Eastern and Western Targets. Analytical results for holes CO-01 and CO-02, drilled at the Eastern Target and disclosed in the Company's October 21s, 2025, news release, are expected within the next two weeks.
Results for holes CO-03 through CO-05 will be announced once received, validated, and reviewed by GoldHaven's technical team. GoldHaven will continue advancing the program over the coming weeks, integrating geological, structural, and geochemical data to refine targeting along both the East and West anomalies. Assay results from the initial drill holes are expected in the near term.
