GoldHaven Defines Property-Scale Porphyry-Related Zonation at Magno, Highlighting Copper, Silver, Tungsten and Critical-Mineral Potential

Executive Summary

• GoldHaven released a comprehensive mineral‑zonation model for its Magno Project, confirming classic porphyry‑related metal zoning and expanding the geochemical dataset.
• High‑grade intercepts were reported, including copper up to 6,660 ppm in granite, zinc up to 13.8 % Zn, tungsten occurrences, and pathfinder anomalies of bismuth (10,000 ppm) and tellurium (67 ppm).
• The company will use the new data to refine 3‑D models, prioritize drill targets across copper‑molybdenum, Ag‑Pb‑Zn, tungsten‑skarn and critical‑mineral zones, and move toward permitting and drilling.

Key Details

• Geological Interpretation: Integrated mapping, sampling and geochemistry support a porphyry source model with stacked Cu‑Au, Ag‑Pb‑Zn, W‑skarn and critical‑mineral targets.
• Top Highlights:
• Property‑scale metal zoning validates intrusion‑driven system.
• Historical Ag‑Pb‑Zn mineralization verified at Magno and D Zones.
• Tungsten confirmed at Kuhn and Dead Goat (high‑temp skarn).
• Copper values up to 6,660 ppm (including 1,760 ppm Cu in granite).
• Bismuth up to 10,000 ppm; tellurium up to 67 ppm indicate high‑temperature fluid pathways.
• Key Metal Results:
• Zn up to 13.8 % at Kuhn; 8.37 % at Dead Goat.
• Cu up to 6,660 ppm at Magno; 1,760 ppm within intrusive rocks.
• Ag‑Pb‑Zn high grades confirmed in Magno and D Zones.
• Base Metal Ratios (Table 1): Provided average Zn/Pb, Zn/Cu, Zn/Ag, Pb/Cu, Pb/Zn ratios for Magno, Middle D, Upper D, Kuhn, Dead Goat.
• Pathfinder Anomalies: Bismuth up to 10,000 ppm (Kuhn, south of Lamb, Magno); Antimony up to 2,120 ppm at Magno; Indium anomalies associated with Zn zones.
• Comparative Context: Zonation pattern comparable to Morococha (Peru) and Coeur Mining’s Silvertip Mine, but with a broader suite including W, Cu, Bi, Te, In.
• Next Steps: Refine 3‑D geological/metal‑zonation models; prioritize drill targets for porphyry Cu‑Mo, CRD Ag‑Pb‑Zn, tungsten‑skarn and critical‑mineral zones; advance permitting across priority areas.
• Project Scope: Magno covers 36,973 ha in the Cassiar Terrane, ~3 km south of historic Cassiar town, with highway access (Highway 37) and proximity to neighboring claim holders (Cassiar Gold Corp., Coeur Mining Inc.).
