GoldHaven Expands District-Scale Airborne Survey at Magno to 2,237 Line-Kilometres to Advance 2026 Drill Targeting

GoldHaven Resources Corp. has announced an expansion of its high-resolution airborne geophysical survey at the Magno Project in British Columbia, increasing the scope from 1,741 line-kilometres to approximately 2,237 line-kilometres. The company is utilizing Dias Airborne Limited's QMAGT (Quantum Magnetic Gradiometry Tensor) technology. This expansion is designed to refine drill targets for a planned 5,000-metre diamond drilling program scheduled for 2026, focusing on the Magno, Kuhn, and D Zones. The survey aims to define structural controls, intrusive contacts, and mineralized corridors associated with Carbonate Replacement Deposits (CRD), tungsten-bearing skarn, and porphyry-style systems. Recent surface sampling has identified high-grade values including up to 2,370 g/t Ag, 6,550 ppm W, and 334 ppm In. The CEO stated this represents a "major advancement" in their systematic approach to unlocking district-scale potential.

The news is classified as Routine - Positive. While the expansion of the survey indicates management confidence and active execution of the funded exploration program, it does not constitute a material change in valuation drivers at this stage. The financing required for this work was already secured through the $3.26 million flow-through offering closed on May 14, 2026, and the C$5.0 million LIFE offering announced in late April. Expanding a survey from ~1,700 km to ~2,200 km is an incremental operational step rather than a transformative event like a discovery or acquisition. The market has already priced in the exploration budget through previous financing announcements. However, it confirms that capital is being deployed efficiently ahead of the critical drilling phase, reducing execution risk slightly compared to a scenario where funding was uncertain.

GoldHaven Resources Corp. is an exploration company focused on critical minerals and precious metals in Tier-1 jurisdictions (Canada) and high-potential greenfields (Brazil). * Flagship Project: The Magno Project in the Cassiar District, British Columbia (~37,000 hectares). It is a district-scale polymetallic system targeting Silver-Lead-Zinc CRD, Tungsten Skarn, and Indium. Recent surface sampling has shown bonanza-grade values (Ag up to 2,370 g/t, W up to 6,550 ppm). * Secondary Project: The Copecal Gold Project in Brazil (Mato Grosso State). Inaugural drilling was completed in late 2025/early 2026, with Phase II planned for Q2 2026. It targets intrusion-related gold systems within the Alta Floresta Gold Province. * Other Assets: Three Guardsmen Project (BC) showing high-grade copper surface samples up to 15.85% Cu.
