GoldHaven expands airborne survey to 2,237 line-km at Magno
VANCOUVER, British Columbia, May 28, 2026 (GLOBE NEWSWIRE) -- GoldHaven Resources Corp. (“GoldHaven” or the “Company”) (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) is pleased to announce the expansion and ongoing completion of its high-resolution airborne geophysical survey across the Company’s 100%-owned Magno Project located in the Cassiar District of northern British Columbia.
The survey, being completed by Dias Airborne Limited (“Dias”), has been expanded to approximately 2,237 line-kilometres from the originally planned 1,741 line-kilometre program, substantially increasing coverage across priority mineralized corridors and prospective intrusive contact zones identified throughout the district-scale property package.
Highlights
- Expanded airborne survey increased to approximately 2,237 line-kilometres from the previously announced 1,741 line-kilometre program
- Survey designed to support a planned 5,000 metre 2026 diamond drill program targeting the Magno, Kuhn, and D Zones
- Expanded coverage across prospective CRD, tungsten-bearing skarn, and porphyry-style mineralized corridors
- High-grade surface sampling includes values up to 2,370 g/t Ag and 6,550 ppm tungsten (W)
- Dias’ QMAGT technology was utilized in geophysical targeting work associated with the Hercules Metals Leviathan discovery in Idaho
“This expanded airborne program represents a major advancement in our systematic approach to unlocking the district-scale potential at Magno,” stated Rob Birmingham, CEO of GoldHaven. “Dias’ technology was successfully utilized in advancing targeting work associated with the Hercules discovery, and we believe deploying the same next-generation system at Magno significantly strengthens our ability to define and prioritize high-confidence drill targets ahead of our planned 2026 drill campaign focused on the Magno, Kuhn, and D Zones.”
The helicopter-borne survey utilizes Dias’ proprietary QMAGT (Quantum Magnetic Gradiometry Tensor) technology, an advanced full tensor magnetic gradiometry system designed to enhance the detection and modelling of subsurface geological structures, alteration corridors, intrusive contacts, and potential mineralized feeder systems.
The airborne survey is focused on defining structural controls, intrusive contacts, and alteration pathways associated with the Company’s growing inventory of silver-lead-zinc CRD mineralization, tungsten-bearing skarn systems, and interpreted porphyry-related mineralized centres.
The expanded survey area covers a broad north-south mineralized corridor associated with carbonate and sedimentary rocks in contact with intrusive granitic units, which management believes represents a highly prospective environment for multiple styles of mineralization.
Recent surface exploration completed by the Company identified multiple high-priority target areas highlighted by rock sample results including silver values up to 2,370 g/t Ag, tungsten values up to 6,550 ppm W, and indium values up to 334 ppm In. These results, together with historical exploration datasets and geological mapping, have been incorporated directly into the airborne survey design and targeting process.
The survey is being flown at 100 metre line spacing with approximately 344 survey lines and average line lengths of approximately 6.5 kilometres. The program is designed to generate a detailed magnetic dataset capable of assisting with the identification of fault structures, lithological boundaries, intrusive geometries, and potential mineralized trends beneath areas of limited outcrop exposure.
GoldHaven believes the integration of this new geophysical dataset with geological mapping, surface geochemistry, historical drilling, and ongoing 3D modelling initiatives has the potential to significantly refine and prioritize drill targets ahead of the Company’s planned 2026 exploration activities.
GoldHaven selected Dias based in part on the geological similarities between Magno’s evolving CRD-skarn-porphyry system and the Hercules Metals Corp. Leviathan discovery in Idaho, where Dias’ advanced airborne geophysical technology played an important role in refining concealed drill targets associated with the discovery1. Management believes the application of comparable high-resolution geophysical techniques at Magno has the potential to materially improve target definition across multiple mineralized corridors.

About the QMAGT Survey System
Dias Airborne’s QMAGT system is a helicopter-borne full tensor magnetic gradiometry platform utilizing SQUID (superconducting quantum interference device) sensor technology. Unlike conventional magnetic surveys, QMAGT measures the full tensor of the Earth’s magnetic field, providing enhanced directional and structural information that can improve subsurface geological interpretation and targeting.
The system is designed to operate effectively in complex terrain environments and has been utilized in modern mineral exploration programs focused on identifying concealed intrusive systems, structural corridors, and mineralized targets.
