GoldHaven Resources Confirms High-Grade Copper Mineralization at Three Guardsmen Project

Executive Summary

• GoldHaven Resources reports high‑grade surface copper mineralisation on its 100 % owned Three Guardsmen property in northern British Columbia.
• Surface grab samples returned exceptional grades, including 15.85 % Cu, 12.75 % Cu and 12.65 % Cu.
• 25 of 126 collected samples exceed 1 % Cu, confirming widespread high‑grade mineralisation over more than 1 km of strike and suggesting a larger skarn system with potential porphyry source.

Key Details

• Sample Program: 126 surface rock samples (grab & chip) collected in 2025.
• Top Grades:
• Sample J647161 – 15.85 % Cu (158,500 ppm)
• Sample J647629 – 12.75 % Cu (127,500 ppm)
• Sample J647753 – 12.65 % Cu (126,500 ppm)
• High‑Grade Frequency: 25 samples >10,000 ppm Cu (≥1 % Cu).
• Geology: Copper occurs in epidote–magnetite skarns with extensive malachite staining; porphyritic intrusions show elevated Cu and Mo at low elevations.
• Strike Length: Skarn mineralisation traced over >1 km; potential extension to 2.6 km between Canadian Verdee and Mildred showings.
• Metal Associations: Geochemical transitions from Cu‑Ag → Bi‑Te‑Au → Mo suggest vector toward an intrusive heat source, possibly a nearby porphyry system.
• Tenure Size: 14 contiguous mineral tenures covering 16,234 ha in the Atlin Mining Division.
• CEO Comment (Rob Birmingham): “These assays are a major milestone…high‑grade copper grades up to 15.85 % at surface…the project offers exceptional upside as we continue to advance exploration.”
• Qualified Person: Lindsay Bottomer, P.Geo., NI 43‑101 qualified.
