Survey reveals continuous north-south magnetic corridor linking known tungsten, silver, zinc, copper and indium occurrences within a single district-scale geological framework — drill program with Northtech advancing toward August mobilization
VANCOUVER, British Columbia, July 15, 2026 (GLOBE NEWSWIRE) -- GoldHaven Resources Corp. ("GoldHaven" or the "Company") (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) is pleased to announce the successful completion and interpretation of its high-resolution airborne QMAGT magnetic survey over the Company's 100%-owned Magno Project in northern British Columbia.
Completed by Dias Geophysical, the survey comprised 2,320.7 line-kilometres flown at 100-metre line spacing, producing what GoldHaven believes is the most detailed modern airborne magnetic dataset collected across the Magno Project. Interpretation of the dataset has now been completed, defining a continuous district-scale structural corridor that links numerous known mineral occurrences while identifying multiple previously unrecognized exploration targets across the Company's 37,000+ hectare land package.
Why the Survey Matters
Completed 2,320.7 line-kilometres of high-resolution airborne magnetic surveying at 100-metre line spacing.
Largest modern airborne magnetic survey completed over the Magno Project.
Defines a continuous north-south magnetic and structural corridor linking numerous known mineral occurrences within a common geological framework.
Known occurrences within the corridor include surface values of up to 2,370 g/t Ag, 6,550 ppm W and 334 ppm In — one of the highest indium values ever recorded in the Cassiar District.
Identifies multiple previously unrecognized magnetic anomalies, structural intersections and intrusive-related features across the property.
Integrates airborne geophysics with geological mapping, historical drilling and surface geochemistry to substantially improve drill targeting.
Northtech Drilling engaged for the Company's inaugural 5,000–7,000 metre drill program, with mobilization targeted for approximately August 1, 2026, subject to permitting.
CEO Commentary
"This survey represents a major technical milestone for the Magno Project. For the first time, we can see how the historic Kuhn tungsten skarns, the Magno and D Zone CRD system and the recently acquired Cassiar Moly target fit within a single regional structural framework.
The survey demonstrates that Magno is not a collection of isolated historical showings—it is one connected mineral system with coherent structural architecture that we can now systematically map, model and drill.
With Northtech advancing toward mobilization, this interpretation provides the strongest geological framework we've ever had for drill targeting across the property."
Rob Birmingham – President & CEO, GoldHaven Resources Corp.
The survey has significantly advanced GoldHaven's understanding of the district-scale geological architecture underlying the property. Interpretation of the data defines a continuous north-south magnetic and structural corridor that spatially correlates with numerous known occurrences of tungsten, silver, lead, zinc, copper and molybdenum mineralization. In addition, the survey has identified multiple previously unrecognized magnetic anomalies, structural intersections and intrusive-related magnetic features that significantly enhance the Company's ability to prioritize future drill targets.
The survey encompasses the Company's principal exploration areas, including the historic Kuhn and Dead Goat tungsten zones, the Magno and D Zone silver-lead-zinc targets, and the recently acquired Cassiar Moly target. For the first time, GoldHaven now has a consistent, property-wide geophysical framework linking these mineralized centres within a single regional geological setting.
The new airborne dataset provides GoldHaven with a consistent geological framework across more than 37,000 hectares of prospective ground. By integrating the magnetic data with historical drilling, surface geochemistry and geological mapping, the Company can more effectively prioritize drill targets, evaluate the relationship between known mineral occurrences and systematically explore areas that have seen little or no previous work.

Connecting the Mineral System
Prior to the airborne survey, Magno was interpreted largely as a collection of individual mineral prospects distributed across a large land package. Interpretation of the new magnetic dataset fundamentally changes that understanding.
The data defines a continuous north-south magnetic and structural corridor extending across much of the Company's 37,000+ hectare property. Historical occurrences of tungsten, silver, lead, zinc, copper, molybdenum and indium all occur within this common structural framework, suggesting they may represent expressions of a much larger mineralized system rather than isolated occurrences.
The vertical magnetic gradient product enhances structural resolution by clearly defining major geological contacts, lineaments and structural intersections. Many of these features have seen little or no historical exploration and represent priority targets for follow-up mapping, prospecting and drilling.
This regional perspective substantially improves GoldHaven's understanding of the geological controls on mineralization while providing a robust framework for systematic exploration across the project.
Historic Tungsten System Enhanced by New Geophysical Data
One of the most significant outcomes of the survey is the enhanced understanding of the Kuhn-Dead Goat tungsten corridor, where historical exploration outlined a historical estimate of approximately 616,500 tonnes grading 0.48% WO₃ across four modelled mineralized lenses. GoldHaven is not treating this historical estimate as a current mineral resource or mineral reserve but considers it highly relevant in guiding ongoing exploration and drill targeting.
Historical drilling within the Kuhn Zone intersected numerous high-grade tungsten-bearing skarn intervals, including:
13.0 metres grading 0.55% WO₃
11.3 metres grading 0.59% WO₃ and 0.10% MoS₂
6.0 metres grading 0.58% WO₃
4.4 metres grading 0.75% WO₃ and 0.17% Cu
4.0 metres grading 1.32% WO₃ and 0.26% MoS₂
A Qualified Person has not completed sufficient work to classify the historical estimate as a current mineral resource or mineral reserve, and GoldHaven is not treating the historical estimate as a current mineral resource or mineral reserve. The historical estimate is considered relevant to investors as it demonstrates the presence of a significant tungsten-bearing system and assists in guiding exploration and drill targeting.
The new airborne magnetic survey demonstrates that the historic Kuhn-Dead Goat tungsten system is situated within a much larger regional structural framework extending across the Magno Project. This significantly improves GoldHaven's understanding of the geological setting surrounding the historical tungsten mineralization while providing a stronger technical basis for evaluating extensions of the system and identifying additional drill targets.
Indium and Critical Mineral Context
Beyond tungsten, the Magno Project has returned surface indium values of up to 334 ppm, representing the highest indium values reported in the Cassiar District. Both indium and tungsten are recognized as critical minerals by Canada and the United States due to their importance in advanced manufacturing, defence technologies and semiconductor supply chains.
The identification of both metals within the same district-scale structural corridor further enhances the strategic significance of the Magno Project and supports continued systematic exploration of the broader mineral system.
