GoldHaven Resources Advances Drilling with Second Hole Completed on Copecal Gold Project

Executive Summary

• Completed second diamond drill hole (COP‑002) to 121 m depth, confirming lithologies and showing enhanced alteration/veining versus the first hole.
• Geological logging and sampling are underway; assay results will be generated by ALS Laboratories in Brazil and Minas Gerais.
• Drill rig has been moved to a third pad ~100 m west to continue testing continuity of the mineralized corridor.

Key Details

• Hole COP‑002 depth: 121 metres.
• Alteration/veining observations: Broader silicification zones, localized biotite alteration, quartz veining with sericite‑chlorite and weak carbonate alteration – all indicative of hydrothermal gold systems.
• Comparison to COP‑001: Enhanced intensity of alteration and veining relative to the first hole.
• Sampling plan: Core will be sampled for gold and multi‑element geochemistry; preparation at ALS Labs (Cuiabá) with analysis at ALS analytical laboratory (Belo Horizonte).
• Next drill target: Third pad positioned ~100 m west along strike from COP‑001/002 to test continuity of the East Target’s mineralized corridor.
• Project context: Copeçal lies within the Alta Floresta Gold Province, part of the Juruena Gold Belt, a historically productive region with multiple deposit styles (mesothermal, intrusion‑related, porphyry, epithermal).

Notable Quotes

“We’re encouraged by the geological consistency and strengthening alteration we’re seeing in our first two drill holes at Copeçal,” – Rob Birmingham, President & CEO, GoldHaven Resources.
“These early results support our interpretation of a large, structurally controlled system with the potential to host gold mineralization.”

Materiality Assessment: Material – Positive (the drilling update provides substantive new geological information that could materially affect the valuation and future development of the Copeçal Gold Project).
