GoldHaven Identifies Significant Indium Enrichment with Values up to 334 ppm at Magno

Executive Summary

• GoldHaven’s 2025 surface exploration program at the Magno Property identified high‑grade indium values up to 334 ppm, well above crustal background (~0.1 ppm).
• Elevated indium is spatially confined to the Magno, D Zones and Kuhn & Dead Goat showings, correlating with high zinc concentrations and sphalerite‑bearing mineralization.
• The results support the company’s model of structurally controlled fluid flow from intrusive heat sources and provide a strong vector for future drill targeting of potential porphyry systems.

Key Details

• Program Scope: Completed 2025 surface geochemical sampling across the entire 36,973 ha Magno Project; modern analytical techniques applied to all samples.
• Indium Highlights:
• Top assay: 334 ppm In (Sample J647329 – Middle D zone) with 16.65 % Zn.
• Additional high‑grade assays: 229 ppm, 216 ppm, 209 ppm, 203 ppm, 188.5 ppm, 173 ppm, 170 ppm, 162.5 ppm, 127.5 ppm (all with accompanying Zn percentages).
• Spatial Distribution: High‑indium values restricted to Magno, D Zones and Kuhn & Dead Goat showings; these zones also exhibit elevated zinc (>5 % Zn in many samples) and sphalerite mineralization.
• Comparative Context: Surface indium grades (up to 334 ppm) are comparable to published indicated resources at the Mt. Pleasant deposit (45–275 g/t In), underscoring exploration significance.
• Geochemical Interpretation: Indium serves as a geo‑thermometer, indicating proximity to intrusive heat sources; regression analysis shows strong correlation between indium and both copper + zinc and zinc alone (log‑scale).
• Strategic Importance: Indium is designated a critical mineral in the U.S. and Canada, with demand driven by touchscreens, flat‑panel displays, compound semiconductors, photonics, fiber‑optic communications, high‑frequency electronics, and thin‑film solar technologies. Supply constraints (by‑product of zinc refining) heighten its strategic value.
• Future Work: Results will guide ongoing geological interpretation and future drill targeting aimed at locating potential porphyry sources within the district‑scale land package.

Notable Quotes

“The completion of this additional geochemical interpretation represents an important step in advancing the Magno Property,” said Rob Birmingham, CEO, “By applying a consistent, modern geochemical approach across the property, we were able to confirm meaningful indium enrichment and its association with zinc‑rich mineralization in key zones… these results increase our understanding of the mineral system and will help guide … future drill targeting.”
