GoldHaven Resources Completes Diamond Drilling at Copecal Gold Project, Reports Sulphide Mineralisation at East Target

Executive Summary

• GoldHaven completed its first-ever diamond drilling campaign at the Copeçal Project (9 holes, 1,085.7 m total).
• Sulphide mineralisation was intersected in the Eastern Gold‑in‑Soil anomaly (≈30 m of chalcopyrite‑pyrite in Hole COPE‑PDH‑004 and ≈5 m of bornite‑chalcopyrite‑pyrite in follow‑up Hole COPE‑PDH‑009).
• A deep saprolite profile (~60 m) was encountered in the Western anomaly, indicating potential for gold mineralisation within weathered material. Assay results are pending.

Key Details

• Program Scope: 9 diamond drill holes (5 East, 4 West), total depth 1,085.70 m; drilling period 10 Oct 2025 – 10 Dec 2025.
• Hole‑by‑hole statistics (selected):
• COPE‑PDH‑004 – 100.25 m depth, azimuth 173.93°, dip 60.58°; intersected ~30 m chalcopyrite‑pyrite zone.
• COPE‑PDH‑009 – 196.15 m depth, azimuth 180°, dip 80°; intersected ~5 m bornite‑chalcopyrite‑pyrite zone (follow‑up to Hole 004).
• COPE‑PDH‑005 – 008 – Western targets; each drilled 84–143 m, collectively revealing a saprolite profile extending to ~60 m depth with shearing, alteration and quartz veining.
• Geological observations – East anomaly:
• Sulphide mineralisation associated with phyllic alteration (sericite‑quartz‑pyrite‑carbonate).
• First occurrence of bornite on the property, suggesting multi‑phase hydrothermal activity.
• Geological observations – West anomaly:
• Thick weathered saprolite; no visible sulphides but notable shearing, alteration and quartz veining.
• Potential oxidation of primary sulphide mineralisation within the weathered zone.
• Assay status: All core logged and sampled; samples to be submitted to ALS Laboratories before year‑end; results will be disclosed per CSE requirements.
• Forward‑looking statements: Company expects the geological insights to refine targeting for future drilling and exploration planning across both anomalies and other prospective zones identified in a new 3D dataset.
