GoldHaven Completes 2,320-Line-km District-Scale Airborne Survey at Magno, Advancing 2026 Drill Target Generation

Executive Summary

• GoldHaven Resources has successfully completed a district-scale QMAGT airborne geophysical survey over its 100%-owned Magno Critical Minerals Project in northern British Columbia.
• The program collected approximately 2,320 line km of high-resolution data across a 37,000+ hectare land package to map structural corridors and prioritize drill targets for silver, lead, zinc, tungsten, and copper.
• The company is now transitioning to data processing and interpretation, with plans to integrate the geophysical dataset with historical exploration and surface sampling ahead of its inaugural district-scale drill program in 2026.

Key Details

• Survey Scope & Specs: ~2,320 line km of high-resolution QMAGT data collected at 100-metre line spacing across a 37,000+ hectare land package in the Cassiar Mining District.
• Target Metals: Designed to enhance targeting of silver, lead, zinc, tungsten, and copper mineralization.
• Historical/Surface Sampling Context: Recent high-grade surface sampling includes values up to 2,370 g/t Ag, 6,550 ppm W, 334 ppm In, >20% Pb, and 19.25% Zn.
• Current Phase & Next Steps: Transitioned to interpretation and drill target generation; final processing, inversion modelling, and geological interpretation are underway. Next steps include dataset integration, prioritization of high-conviction drill targets, advancement of permitting, and commencement of the inaugural district-scale drill program.
• Administrative Note: Paid additional cash finder’s fees of $22,400 and issued 89,600 finder’s warrants related to a June 9, 2026 private placement, bringing total finder’s fees to $213,465 in cash and 991,760 warrants.
• Qualified Person: Raymond Wladichuk P.Geo. (non-independent consultant) reviewed and approved the technical information.

Notable Quotes

• Rob Birmingham, President & CEO: “I've been waiting for this dataset since the day we assembled this land package. For the first time, we can evaluate Magno as one connected mineral system rather than a collection of isolated historical showings. The preliminary data already highlight an extensive structural framework and numerous magnetic features across the property... I believe the work completed over the coming weeks will define our most systematic drill program to date across the Magno district.”
