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

Preliminary data reveals extensive structural framework and multiple magnetic features across 37,000+ hectares – interpreted results and priority drill targets to follow

VANCOUVER, British Columbia, June 25, 2026 (GLOBE NEWSWIRE) -- GoldHaven Resources Corp. ("GoldHaven" or the "Company") (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) is pleased to announce the successful completion of its district-scale Quantitative Magnetic Tensor ("QMAGT") airborne geophysical survey over its 100%-owned Magno Critical Minerals Project ("Magno" or the "Project"), located in the prolific Cassiar Mining District of northern British Columbia.

The district-scale airborne program was successfully completed as planned, with approximately 2,320-line kilometres of high-resolution geophysical data collected across GoldHaven's 37,000+ hectare land package, creating one of the largest and most comprehensive modern airborne magnetic datasets ever acquired over the Project.

The dataset will be integrated with geological mapping, historical drilling and recent high-grade surface sampling, including values of up to 2,370 g/t silver, 6,550 ppm tungsten and 334 ppm indium, to prioritize drill targets across multiple mineralized trends. With data acquisition now complete, GoldHaven has transitioned into the interpretation and drill target generation phase of its 2026 exploration program.

Survey Highlights

  • 2,320+ line kilometres of high-resolution QMAGT data successfully collected

  • Survey flown at 100-metre line spacing across the Magno Project

  • Covers a 37,000+ hectare district-scale land package in the Cassiar Mining District

  • Designed to enhance targeting of silver, lead, zinc, tungsten and copper mineralization

  • Final processing, inversion modelling and geological interpretation currently underway

  • Results to be integrated with historical exploration, geological mapping and recent surface sampling to prioritize 2026 drill targets

Rob Birmingham, President & CEO of GoldHaven, stated, "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. Several of these features appear spatially associated with known historical mineral occurrences, while additional anomalies have been identified in previously underexplored areas, and we're now integrating those observations with geology and geochemistry to refine drill targets. I believe the work completed over the coming weeks will define our most systematic drill program to date across the Magno district."
