GoldHaven Resources Corp. (CSE: GOH) announced plans for a Phase II diamond drilling program at its Copeçal Gold Project in Brazil following an independent geological review of the company's initial drill campaign.

The independent review validated GoldHaven's exploration model 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.

The Phase II program is designed to consist of approximately five to six drill holes totaling approximately 1,200 metres. The drilling will 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.

At the East Target, the consultant confirmed a northerly dipping, shear-hosted mineralized zone with distinct zoned sulphide assemblages including chalcopyrite-pyrite and chalcopyrite-bornite, suggesting increasing temperature. At the West Target, key features included higher-grade gold enrichment associated with fold structures and dense sheeted quartz veinlet systems.

The company stated that its 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 Magno Project in British Columbia.

"We are very encouraged by the conclusions of the independent geological review, which reinforces our belief that Copeçal hosts a large-scale hydrothermal system," stated Rob Birmingham, Chief Executive Officer of GoldHaven.

The Copeçal Gold Project is located within the Alta Floresta Gold Province in Brazil. Historical work by AngloGold Ashanti outlined a six-kilometre gold-in-soil anomaly across the project area. The second phase drilling program is planned to commence during the second quarter of 2026, subject to final logistical planning and contractor availability.
