GoldHaven Advances 2026 Drill Targeting at Magno; Permit Application Submitted

VANCOUVER, April 01, 2026 - GoldHaven Resources Corp. ("GoldHaven" or the "Company") (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) is pleased to provide an update on its 2026 exploration plans at its flagship Magno Project, located in the Cassiar District of northern British Columbia.

Highlights

• Drill targeting underway for the Magno, Kuhn and D Zones
• Permit application submitted for the 2026 drill program
• Airborne magnetic survey planned to generate first modern property-wide geophysical dataset
• 3D geological modelling underway to support drill targeting
• Recent and historical results include up to 2,370 g/t Ag, >20% Pb, 19.25% Zn, 6,550 ppm W and 334 ppm In
  

CEO Commentary

"We are entering an exciting and highly strategic phase at Magno, where multiple high-grade zones and distinct mineralization styles have now been defined across a large, consolidated land package," stated Rob Birmingham, President & CEO of GoldHaven. "With clear drill targets emerging at the Magno, Kuhn and D Zones, alongside the submission of our permit application and the commencement of airborne geophysics and 3D modelling, we believe the Company is well positioned to execute a disciplined 2026 drill program. The combination of high-grade silver-lead-zinc mineralization and growing exposure to critical minerals such as tungsten and indium continues to reinforce our view that Magno hosts the hallmarks continues to reinforce our view that Magno is emerging as a compelling district-scale silver and critical minerals exploration opportunity in the Cassiar District."

2026 Drill Program Targeting

GoldHaven is advancing a targeted 2026 drill program focused on three highly prospective zones:

• Magno Zone - High-grade silver-lead-zinc carbonate replacement (CRD) style mineralization
• D Zone - Additional CRD-style mineralization with strong Ag-Pb-Zn values
• Kuhn Zone - Tungsten-rich skarn mineralization with associated base metals
  

These zones collectively suggest strong metal zonation consistent with a large-scale, intrusion-related system associated with the Cassiar Stock.

The upcoming drill program will focus on confirming historical results and testing the continuity and scale potential of mineralization across these key zones.

High-Grade Results Support Drill Targeting

Surface sampling and historical work across the property have returned significant grades, including:

• Silver (Ag): up to 2,370 g/t, with 45 samples exceeding 100 g/t
• Lead (Pb): greater than 20%
• Zinc (Zn): up to 19.25%
• Tungsten (W): up to 6,550 ppm, with 32 samples exceeding 1,000 ppm
• Indium (In): up to 334 ppm, associated with sphalerite
  

Widespread tungsten mineralization has been confirmed at the Kuhn and Dead Goat Zones, while high-grade CRD-style silver-lead-zinc mineralization has been verified at the Magno and D Zones. These results highlight a property-scale metal zonation pattern, transitioning from distal silver-lead-zinc mineralization to proximal tungsten skarn and copper-bearing intrusive systems. This interpreted zonation pattern, combined with historical drilling and mapped skarn development, forms the basis for the Company's 2026 drill targeting strategy.

Geophysics and Target Development

The Company is currently engaging a contractor to complete a detailed airborne magnetic survey over the entire Magno Project. This will represent the first modern, property-wide geophysical survey across the consolidated land package.

In parallel, GoldHaven is constructing a comprehensive 3D geological model integrating historical drilling, surface sampling, and geophysical datasets. This work is expected to significantly enhance drill targeting and define additional priority zones.

"The integration of modern airborne geophysics with our growing 3D geological model is a major step forward for Magno," added Rob Birmingham, President & CEO of GoldHaven. "For the first time, we will have a property-wide modern dataset across this consolidated district-scale land package, which we believe will materially improve our ability to prioritize high-conviction drill targets in 2026."

The Company is also evaluating a ground-based 3D induced polarization (IP) survey to further refine targets and identify potential subsurface mineralization.

Permitting Update

GoldHaven has submitted its permit application to the Ministry of Mines for the 2026 drill program and is currently awaiting approval.

The Company remains on track to initiate drilling upon receipt of permits.
