GoldHaven Highlights Multi-Target Drill Opportunity Across Permitted Magno Project

VANCOUVER, British Columbia, Sept. 29, 2026 (GLOBE NEWSWIRE) -- GoldHaven Resources Corp. (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) (“GoldHaven” or the “Company”) is pleased to highlight that, while current drilling is focused on the Kuhn target, GoldHaven’s amended Mines Act Permit provides the Company with significant flexibility to systematically evaluate multiple high-priority exploration areas across the broader Magno Project.

The permit authorizes up to 93 ground-based drill pads across seven work zones, four staging areas, modifications to up to 45 kilometres of existing access, and additional exploration trail construction within the approved work program.

Highlights

• 93 permitted drill pads across seven work zones provide flexibility to test multiple targets across Magno.
• 2026 drilling is underway at Kuhn, targeting tungsten-bearing skarn mineralization.
• D Zone / Magno hosts high-grade historical silver-lead-zinc mineralization, including 7.6 metres grading 240 g/t Ag, 4.73% Pb and 4.74% Zn.
• The broader project hosts tungsten, silver, lead, zinc, copper and critical-mineral potential within a large intrusion-related system.
• Permitted targets extend beyond Kuhn to include Dead Goat, D Zone / Magno, Lamb Mountain, Contact and Lang Creek.
  

Rob Birmingham, President and CEO of GoldHaven, commented:

“Kuhn remains a key focus of our 2026 drill program, but it is also one part of a much broader mineralized system. With 93 permitted drill pads across seven work zones, we have the flexibility to evaluate multiple targets across a large project footprint. As drilling advances at Kuhn, our technical team is also evaluating D Zone and other priority areas across Magno to determine how best to allocate the remainder of our 2026 drill program.”

A Multi-Target Exploration Opportunity

GoldHaven’s permitted exploration footprint encompasses several areas of geological interest across Magno and provides the Company with multiple opportunities to evaluate different mineralization styles within the broader property-scale system.

Kuhn and Dead Goat

The current focus of GoldHaven’s 2026 drill campaign and the Company’s principal tungsten-skarn target area. Historical and modern work has identified tungsten-bearing skarn developed within favourable carbonate stratigraphy adjacent to intrusive rocks.

At Kuhn, two principal skarn horizons, the Lower and Upper 3a, have been traced at surface for approximately 640 metres and 206 metres, respectively, with geological mapping indicating potential strike extensions of up to approximately 2 kilometres. The skarns are characterized by diopside-garnet assemblages with scheelite, pyrrhotite and locally molybdenum and base-metal mineralization. Similar tungsten-bearing skarn occurs at Dead Goat, where mineralization has been mapped over a surface expression of up to approximately 200 metres.

D Zone / Magno Area

A high-priority polymetallic target area characterized by silver-lead-zinc mineralization hosted within carbonate rocks of the Lower Cambrian Atan Group. Historical and recent work has identified structurally controlled skarn and carbonate-replacement-style mineralization occurring as bedding-parallel “manto” bodies and crosscutting “chimney”-style zones.

Mineralization includes galena, sphalerite, magnetite and locally massive sulphides, providing the Company with a distinctly different target style from the tungsten-focused Kuhn area.

Historical drilling at the D Zone included a reported interval of 7.6 metres grading 240 g/t silver, 4.73% lead and 4.74% zinc. This historical result predates NI 43-101 and has not been independently verified by a Qualified Person for GoldHaven.

More recent exploration has confirmed strong silver-lead-zinc mineralization across the broader Magno and D Zone trend, including silver values exceeding 2,000 ppm in structurally controlled skarn mineralization.

Lamb Mountain

A permitted exploration area located north of the central Magno target area and positioned within the broader intrusive and mineralized system being evaluated by GoldHaven. Property-wide geochemical work has identified elevated high-temperature pathfinder elements in the broader area south of Lamb Mountain, including anomalous bismuth, which forms part of the dataset being used to trace structural fluid pathways and vector toward potential intrusive sources.

Contact Area

A centrally located permitted exploration area positioned within the broader Magno intrusive and carbonate-contact environment. The Magno Project covers the contact between Cretaceous-aged intrusive rocks and carbonate-rich sedimentary rocks of the Cassiar Terrane, a geological relationship interpreted to control much of the property’s skarn and carbonate-replacement mineralization. The Contact Area provides an opportunity to evaluate additional sections of this favourable intrusive-carbonate interface.

Lang Creek

A permitted exploration area in the southern portion of the Magno Project, located near Highway 37 and forming part of GoldHaven’s broader strategy to evaluate mineralization across the entire property. Its location provides an additional opportunity to evaluate prospective geology along the southern extent of the Magno system while benefiting from nearby road access. The Company intends to integrate geological mapping, historical information, geochemistry and geophysical data when prioritizing future drilling across Lang Creek and other permitted target areas.

The approved work program provides access to the Kuhn and Dead Goat, Granite D / Magno, Lamb Mountain, Contact and Lang Creek areas, allowing GoldHaven to progressively evaluate multiple target styles across the broader Magno mineral system.

Property-Scale Geological Framework

GoldHaven’s recent work has helped define a broader property-scale mineral zonation model at Magno. Integrated geological mapping, sampling and geochemical analysis indicate an intrusion-related system with copper-gold-silver mineralization in more proximal settings, silver-lead-zinc mineralization in intermediate zones, and tungsten-skarn and additional replacement-style mineralization elsewhere across the property.

Recent work has identified copper values of up to 6,660 ppm at Magno, elevated copper within intrusive rocks, tungsten mineralization at Kuhn and Dead Goat, and strong bismuth and tellurium anomalies interpreted as high-temperature pathfinder elements and indicators of structural fluid pathways. Elevated indium associated with zinc mineralization further reinforces the project’s broader critical-mineral potential.

Building Beyond Kuhn

GoldHaven is currently evaluating the sequencing and prioritization of additional targets as drilling progresses at Kuhn. Geological observations, historical exploration data, surface geochemistry and geophysical information are being integrated to determine where additional drill metres can generate the greatest exploration value.

The Company expects to provide further updates regarding target prioritization and drilling plans as the 2026 program progresses.
