Independent Review Confirms Large-Scale Hydrothermal System at GoldHaven's Copeçal Project
VANCOUVER, British Columbia – GoldHaven Resources Corp. has announced that an independent specialist geology consultant has validated and enhanced the geological understanding of its 100%-owned Copeçal Project in Mato Grosso State, Brazil. The review followed a detailed analysis of drill core and data from the company's inaugural diamond drilling program, which consisted of nine holes totaling 1,085.7 meters.
Key Findings from the Independent Review
The independent review confirmed the potential for a large-scale, structurally controlled hydrothermal gold system at Copeçal. Clear vectors to higher-grade mineralization were identified at both the East and West Targets. The project features an approximately six-kilometer gold-in-soil anomaly, defining a district-scale system with large, underexplored zones originally identified by AngloGold Ashanti.
West Target Insights
At the West Target, gold mineralization is linked to fold hinge zones and increasing sheeted vein density, providing a vector towards potentially stronger mineralization. The presence of sheeted veining with quartz rimmed by biotite indicates potassic alteration, a key signature of intrusion-related hydrothermal systems.
East Target Insights
The East Target exhibits a copper-gold system with zoned sulphide assemblages, including chalcopyrite and bornite, providing a higher temperature vector. Surface gold enrichment in soil and saprolite further supports the potential for deeper mineralization.
Alta Floresta Gold Belt Context
The Copeçal Project is situated within the Alta Floresta Gold Belt, a prolific and emerging gold district in Brazil. The independent review reinforces the project's potential as a large-scale mineralized system, with multiple untested high-priority targets remaining open for follow-up drilling.
Management Commentary
Gustavo Almeida, Senior Project Geologist for GoldHaven in Brazil, commented: "The geological features identified at Copeçal during the initial drilling phase are encouraging and consistent with the expected signature of an intrusion-related hydrothermal system. The strong structural kinematic indicators, sheeted veining, and zoned sulphide assemblages suggest we are vectoring towards stronger mineralization. The association of gold and gold-copper anomalism with fold hinge structures and magnetic features provides a technically sound framework for follow-up drilling."
Next Steps
The independent review meaningfully enhances the project's exploration potential ahead of drilling and underpins GoldHaven's strategy to advance an expanded drill program in 2026. The system remains open with significant potential for discovery of higher-grade zones.
