GoldHaven Resources Completes Eight Diamond Drill Holes at Copecal Gold Project in Brazil: Ninth Hole Underway To Follow Up Sulphide Intersection in Hole 4 East Target

Executive Summary

• GoldHaven Resources completed eight diamond drill holes (total 889.55 m) at the Copeçal Gold Project, intersecting disseminated pyrite–chalcopyrite sulphide mineralization in hole COPE‑PDH‑004.
• A ninth follow‑up hole (COPE‑PDH‑009) has been started to test the depth extension of this sulphide zone and will drill ~200 m at the East Anomaly.
• Assay results for holes COPE‑PDH‑004 and saprolite portions of COPE‑PDH‑001/002 are pending; a detailed update will follow once all cores are logged, sampled, and assayed.

Key Details

• Drill Program: 8 completed diamond holes (COPE‑PDH‑001 – COPE‑PDH‑008) totaling 889.55 m; 4 holes at East Target (441.7 m) and 4 at West Target (447.85 m).
• Key Intercept – Hole COPE‑PDH‑004: Sulphide mineralization (fine‑grained pyrite & chalcopyrite) from 79 m to 100.25 m depth within weak‑to‑moderate phyllic alteration (quartz‑sericite‑pyrite‑calcite) in sheared biotite granitoid.
• Significance: First subsurface evidence supporting the strong surface gold anomalism at the East Target; suggests a potential source of the observed gold anomalies.
• Follow‑up Hole – COPE‑PDH‑009: Currently drilling; planned depth ~200 m to test continuity and scale of the sulphide zone intersected in COPE‑PDH‑004.
• West Target Findings: Holes COPE‑PDH‑005 – 008 intersected saprolite (~50 m deep) overlying sheared granodiorite gneiss, biotite schist, quartz veining, and sericite‑rich zones; thicker than expected saprolite noted.
• Assay Status: Results for COPE‑PDH‑004 and saprolite portions of COPE‑PDH‑001/002 are awaited; all cores will be logged, sampled, and submitted for assay after the ninth hole is completed.
• Project Context: Copeçal lies in Brazil’s Alta Floresta Gold Province (Juruena Magmatic Arc), a historically productive region with multiple gold deposit styles nearby. Historical work by AngloGold Ashanti identified extensive gold and arsenic anomalies.

Notable Quotes

“We are encouraged by the progress made during this initial drill campaign at Copeçal… The sulphide interval intersected in Hole COPE‑PDH‑004 is the strongest subsurface evidence we’ve seen to date supporting the robust gold anomalism outlined at surface.” – Rob Birmingham, President & CEO
