Goldhaven Resources Corp. Announces Phase Ii Drill Program At Copeçal Gold Project in Brazil
GoldHaven Resources Corp. announced plans for a Phase II diamond drilling program at its Copeçal Gold Project in Brazil following a positive independent geological review of the Company’s maiden drill campaign and exploration model. The independent review validated key components of GoldHaven’s exploration thesis and confirmed the presence of a large-scale hydrothermal system with intrusive-related gold and base metal mineralization potential. The review identified multiple vectors toward potentially more prospective portions of the system including sulphide zonation, widespread hydrothermal alteration, structural controls, and indications of increasing temperature toward the core of the system. Based on these conclusions, GoldHaven is planning a follow-up, step-out diamond drilling program consisting of approximately five to six drill holes totaling approximately 1,200 metres. The Phase II program is designed to test high-priority targets at depth and along strike at both the East and West Targets, where geological, structural, and geochemical indicators suggest proximity to a potentially more robust mineralized system. The combination of sulphide zonation, intrusive-related alteration, structural controls, and untested geophysical targets supports GoldHaven’s interpretation that Copeçal may represent a larger hydrothermal mineralized system with potential for stronger mineralization at depth and along strike. The Company’s recently announced LIFE financing is expected to provide additional flexibility to evaluate expanded exploration activities across GoldHaven’s portfolio, including potential follow-up drilling at Copeçal and the Company’s flagship Magno Project in British Columbia. At the East Target, the consultant confirmed a northerly dipping, shear-hosted mineralized zone, distinct zoned sulphide assemblages: chalcopyrite–pyrite, chalcopyrite–bornite, suggesting increasing temperature and providing a temperature vector, and elevated magnetic susceptibility in the core of the system. These features represent a clear vector toward potentially stronger mineralization, both at depth and along strike. At the West Target, key features identified include higher-grade gold enrichment associated with asymmetric to isoclinal fold structures, dense sheeted quartz veinlet systems hosted within phyllic altered meta-granodiorite, and potassic alteration, evidenced by crystalline biotite along vein margins within wide intervals indicating potential for a robust hydrothermal system along strike to the west and at depth. The core of the West Target gold-in-soil anomaly remains largely untested and represents a high-priority drill target. This anomaly aligns with a fold hinge and closure zone interpreted from drone magnetic data. The Company continues to advance Copeçal through a multi-disciplinary exploration approach that integrates modern geological interpretation with historical datasets generated by prior operators, including AngloGold Ashanti. This approach combines historical drilling, geochemical and geophysical information with recent field mapping, soil sampling, and diamond drilling results to enhance targeting and improve vectoring toward potentially mineralized centres. The second phase drilling program is currently planned to commence during the second quarter of 2026, subject to final logistical planning and contractor availability. Further updates regarding drill targeting, mobilization timelines, and exploration activities at the Copeçal Project will be provided as they become available. The Copeçal Gold Project is strategically situated within the Alta Floresta Gold Province, a historically productive region that has yielded substantial gold discoveries since the late 1970s. GoldHaven’s tenements cover a total of 3,681 hectares in a geologically favourable setting within the Juruena Gold Province of Brazil. The Juruena Gold Province, also known as the Juruena Magmatic Arc, is an orogenic belt highly prospective for mesothermal shear-related and intrusion-related gold deposits, such as G-Mining’s Tocantinzinho deposit. Additionally, the region hosts recently identified porphyry-style deposits (e.g., Serabi, Jaca) and epithermal-style deposits (e.g., X1, Aura). The presence of multiple deposit styles, along with the confirmation of large-scale gold deposits in the Juruena Province of Brazil, underscores the significant potential of the Copeçal Gold Project. Recent exploration programs, including geochemical soil sampling, drone-mounted magnetometry surveys, and historical drilling data, indicate the presence of multiple gold-bearing structures. Notably, AngloGold Ashanti previously conducted systematic exploration on the property from 2010 to 2016, including auger and air-core drilling, geophysical surveys, and rock geochemistry, identifying multiple zones of anomalous gold mineralization. The Copeçal Gold Project benefits from extensive historical work, with AngloGold Ashanti’s exploration confirming gold and arsenic anomalies, indicative of significant mineralization potential. Soil sampling grids and follow-up auger drilling in key areas revealed consistent gold values over wide zones, further supporting the presence of a substantial mineralized system.
