GoldHaven Announces Drilling at Copecal Gold Project Intersects Sulphide Mineralization in Hole 4 at East Target

Executive Summary

• Drill hole COP‑004 intersected disseminated sulphide mineralization (pyrite + chalcopyite) from 79 m to the bottom of the hole (100.25 m), providing the first subsurface evidence linking the East Target’s gold‑in‑soil anomalies to a potential source zone.
• Six holes have been completed (total 687.4 m); a seventh hole (COP‑007) is underway and an eighth hole is ready, with a ninth hole planned to follow up the COP‑004 intercept.
• Partial assays from holes COP‑001 and COP‑002 returned no economic grades but supplied valuable geochemical and structural data; saprolite results are still pending.

Key Details

• Drill Program Scope: 1,200 m diamond drilling program at the 100 % owned Copeçal Project (Brazil) targeting East and West anomalies.
• Hole COP‑004:
• Intercepted disseminated fine‑grained pyrite + chalcopyite from 79 m to 100.25 m (≈21 m interval).
• Associated weak–moderate phyllic alteration (quartz, muscovite‑sericite, calcite) within sheared medium‑grained biotite granitoid.
• First direct evidence that the sulphide zone may be the source of surface gold‑in‑soil anomalies at the East Target.
• Follow‑up Plans: A new drill hole is being planned to test depth extension of the COP‑004 mineralization; a ninth hole will target the same zone after further analysis.
• Completed Drilling to Date: Six holes (687.4 m total) – 441.7 m (four holes) at East Target, 245.7 m (two holes) at West Target.
• Current Activity: Hole COP‑007 in progress; hole COP‑008 staged and ready for drilling.
• Assay Results: Partial assays from COP‑001 & COP‑002 showed no economically significant grades but provided structural and geochemical insights; saprolite interval results pending.
• Project Context: Copeçal lies within the Alta Floresta Gold Province (Juruena Gold Province), a historically productive region with multiple historic discoveries and recent exploration indicating extensive gold‑bearing structures.

Notable Quotes

“COP‑004 has delivered our most encouraging subsurface evidence to date at Copeçal. The presence of sulphides and alteration over a meaningful interval gives us strong confidence that we are drilling into the system responsible for the extensive gold anomalies at surface.” – Rob Birmingham, CEO
