GoldHaven Advances Copecal Gold Project Following Initial Drilling; Phase 2 Program Planned at West Target

Executive Summary

• GoldHaven completed its inaugural nine‑hole diamond drilling program at the Copeçal Gold Project, confirming anomalous gold and copper mineralization in both West and East Targets.
• The West Target showed the most encouraging results with widespread gold anomalies in saprolite and bedrock, becoming the focus for a Phase 2 drill campaign planned for mid‑Q2 2026.
• Integrated technical review of new core data with historic AngloGold Ashanti datasets is underway to refine the geological model and generate additional high‑priority drill targets.

Key Details

• Program Scope: 9 diamond drill holes across two priority zones (West Target, East Target).
• Geological Highlights:
• Gold‑copper anomalism intersected alongside structural deformation, quartz veining, and phyllic alteration—signatures of a hydrothermal mineralizing system.
• West Target: thick saprolite (~60 m) overlying granodiorite–gneiss host rocks with multiple shear phases, sheeted veinlets, and alteration patterns indicative of fluid pathways.
• Assay Reference: Detailed assay results for West Target (Feb 17 2026 release) and East Target (Dec 17 2025 release) are cited; key intersections illustrated in Figures 2‑3.
• Phase 2 Planning:
• Anticipated start: mid‑Q2 2026.
• Primary focus: expand mineralization and vector toward higher‑grade zones at West Target.
• Technical Review Activities:
• Multi‑element geochemical interpretation.
• Structural analysis of drill core deformation features.
• Alteration mineral characterization.
• Reinterpretation of historic geophysical datasets.
• Physical property testing (resistivity, conductivity) on core samples.
• Project Context: Copeçal lies within the Alta Floresta Gold Province, a historically productive region with multiple deposit styles (mesothermal shear‑related, intrusion‑related, porphyry, epithermal).
