GoldHaven Closes $1.72 Million First Tranche Flow-Through Financing to Fund 2026 Drill Program Targeting High-Grade at Magno Project

HIGHLIGHTS

• $1.72 million first tranche closed at $0.265

• Proceeds directly funding 2026 Magno drill program

• Targeting high-grade zones including up to 2,370 g/t Ag, greater than 20% Pb-Zn, and multi-thousand ppm tungsten

In connection with the Offering, the Company paid cash finder’s fees totaling C$109,817 and issued 397,520 non-transferable finder warrants to certain eligible arm’s-length finders who introduced subscribers to the Offering. Each Finder Warrant entitles the holder to purchase one Common Share at a price of C$0.35 per Finder Share for a period of 24 months from the date of issuance. All securities issued in connection with the offering are subject to a hold period of four months and one day pursuant to applicable securities laws.

CEO COMMENTARY

“We are extremely pleased with the strong support for this financing, which positions GoldHaven to execute a fully funded and highly targeted 2026 drill program at Magno,” stated Rob Birmingham, President and CEO of GoldHaven.

“This program will focus on multiple high-priority zones across Magno, Kuhn, and the D-Zone, where historical and recent work has outlined significant high-grade silver-lead-zinc mineralization, as well as extensive tungsten mineralization. With grades reaching up to 2,370 g/t silver and strong critical mineral associations including tungsten and indium, we believe Magno has the potential to emerge as a large-scale, district-wide polymetallic system.”

USE OF PROCEEDS

The company intends to use the net proceeds of the offering for Canadian exploration expenses that are flow-through critical mineral mining expenditures (as such terms are defined in the Income Tax Act (Canada)).

Funds will be primarily directed toward advancing the Company’s Magno Project, including:

• 2026 diamond drilling program targeting high-grade Ag-Pb-Zn CRD zones at Magno and D-Zone

• Follow-up drilling of tungsten-skarn mineralization at Kuhn and Dead Goat, where values up to 6,550 ppm W have been identified

• Airborne geophysical surveys to refine structural controls and intrusive targets

• 3D geological and metal zonation modelling to vector toward higher-grade zones

• Systematic follow-up of high-grade surface and historical drill results, including multiple samples exceeding 100 g/t Ag

MAGNO PROJECT

GoldHaven’s Magno Project is a district-scale polymetallic exploration asset spanning approximately 37,200 hectares in the Cassiar region of northwestern British Columbia.

The project hosts a large intrusion-related hydrothermal system with multiple mineralization styles, including silver-lead-zinc carbonate replacement mineralization, tungsten-rich skarn systems, copper-b earing intrusions, and critical minerals such as indium, bismuth, and tellurium.

Property-wide geological mapping and geochemical analysis define a classic porphyry-related metal zonation pattern, supporting the interpretation of a large, vertically and laterally extensive mineral system.

MAGNO KEY GEOLOGICAL HIGHLIGHTS

• Property-scale metal zonation consistent with a porphyry source system

• Stacked mineralization including porphyry, CRD, and skarn environments

• Verified high-grade Ag-Pb-Zn mineralization at Magno and D-Zone

• Confirmed widespread tungsten mineralization at Kuhn and Dead Goat

• Elevated copper within intrusive rocks supports a magmatic source

• Strong critical metal enrichment inclu ding indium values up to 334 ppm
