GOLDHAVEN HIGHLIGHTS STRATEGIC TUNGSTEN AND INDIUM EXPOSURE AT MAGNO AMID GROWING FOCUS ON CRITICAL MINERAL SUPPLY CHAINS

Goldhaven Resources Corp. has highlight the growing strategic significance of tungsten and indium identified at its district-scale Magno project in Northern British Columbia amid intensifying Western efforts to secure critical mineral supply chains outside of China.

Highlights:

• Growing Western focus on securing tungsten and critical mineral supply chains outside China;
• Magno hosts multiple tungsten-bearing skarn targets with values up to 6,550 parts per million tungsten;
• Elevated indium values up to 334 parts per million identified within zinc-rich mineralization;
• District-scale 37,000-plus-hectare project prospective for CRD (carbonate replacement deposit), skarn and porphyry mineralization;
• 2026 exploration planning under way, including airborne geophysics and drill targeting.

Chief executive officer commentary

"Global markets are increasingly recognizing the strategic importance of securing Western sources of tungsten and other critical minerals amid growing supply chain concerns," stated Rob Birmingham, chief executive officer of Goldhaven. "We believe Magno represents a district-scale critical minerals opportunity combining tungsten-bearing skarn systems, high-grade silver-zinc-lead CRD mineralization and elevated indium values within one of Canada's premier mining jurisdictions. As we advance airborne geophysics and 2026 drill targeting, we believe Magno continues to demonstrate the characteristics of a large-scale multiphase mineralizing system with significant critical minerals potential."

With airborne geophysics under way, the company is currently advancing permitting and exploration planning for its 2026 exploration campaign, which is expected to include airborne geophysics and drill testing targeting multiple high-priority tungsten-bearing skarn systems, silver-lead-zinc carbonate replacement deposit (CRD) zones and broader porphyry copper-molybdenum targets identified across the project.

Global tungsten markets have experienced significant price appreciation over the past year as supply concerns continue to escalate. China currently dominates global tungsten and indium production and downstream processing capacity while recent geopolitical developments and proposed Western procurement restrictions targeting foreign adversary sourced critical minerals have accelerated interest in North American and allied-source critical mineral projects. Goldhaven believes the Magno project is uniquely positioned within this emerging thematic due to its combination of tungsten-bearing skarn mineralization, high-grade silver-zinc-lead CRD mineralization and elevated indium values associated with zinc-rich sulphide systems. The project remains at an exploration stage and additional work is required to determine the extent and economic significance of identified mineralization.

Goldhaven has identified tungsten mineralization across multiple target areas at Magno, including recent 2025 surface sampling that returned values of up to 6,550 parts per million tungsten. Historical drilling and sampling at the Kuhn zone reportedly returned intervals including 13.0 metres grading 0.55 per cent WO3 (tungsten trioxide), 4.0 metres grading 1.32 per cent WO3 and 0.26 per cent MoS2 (Molybdenum disulphide), and 2.5 metres grading 0.95 per cent WO3. Elevated indium values of up to 334 ppm have also been identified within sphalerite-bearing mineralization, further strengthening the project's strategic critical mineral profile. The company's 2026 exploration program has been designed, in part, to confirm these historical results.

The historical drilling results referenced above are historical in nature and have been obtained from publicly available assessment reports from the government of British Columbia geological databases and have not been independently verified by the company or the qualified person; however, the company believes the information is relevant as it assists in defining exploration targets and guiding continuing geological modelling and targeting efforts.
