GoldHaven Defines District-Scale Structural Corridor at Magno Project

GoldHaven Resources Corp. (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) has announced the definition of a continuous district-scale structural corridor at its Magno Project in British Columbia, following the completion and interpretation of its high-resolution airborne magnetic (QMAGT) survey. This significant development unifies numerous known mineral occurrences within the company's 37,000+ hectare land package into a single geological framework, while also identifying multiple previously unrecognized exploration targets. The company believes this data will substantially improve drill targeting.

Completed by Dias Geophysical with 100-meter line spacing, the 2,320.7 line-kilometer airborne survey represents the most detailed modern airborne magnetic dataset ever collected over the Magno Project. This work has revealed a continuous north-south magnetic and structural corridor linking known occurrences of critical minerals such as tungsten, silver, zinc, copper, and indium. Notably, high-grade surface values within the corridor include up to 2,370 g/t Ag, 6,550 ppm W, and 334 ppm In, with the indium value being one of the highest ever recorded in the Cassiar District. Unlike conventional airborne magnetic surveys, the high-resolution QMAGT technology provides a more detailed view of structural corridors, intrusive bodies, and lithological contacts that may control mineralization.

The integration of this new geophysical data with geological mapping, historical drilling, and surface geochemistry is expected to significantly enhance drill targeting. GoldHaven anticipates that this will improve vectoring towards mineralized systems and refine drill targeting across the Magno, Kuhn, and D Zone target areas. The company has engaged Northtech Drilling for its inaugural 5,000–7,000 meter drill program, with mobilization targeted for approximately August 1, 2026, subject to permitting. This program will focus on the Magno, D, and Kuhn zones, forming a key part of the company's 2026 drilling campaign.

The Magno Project is a district-scale polymetallic exploration asset spanning over 37,000 hectares in the Cassiar Mining District of northern British Columbia. The project hosts multiple styles of mineralization, including high-grade silver-lead-zinc carbonate replacement mineralization, tungsten-rich skarn systems, copper-bearing intrusive rocks, and critical minerals such as indium, bismuth, and tellurium. GoldHaven's 2025 work had defined a property-scale metal zonation pattern consistent with a porphyry-related source system. This survey now allows for the evaluation of Magno as a unified mineral system rather than a collection of isolated historical showings.

Rob Birmingham, President & CEO of GoldHaven, stated that this survey represents a major technical milestone for the Magno Project, expressing that he had been waiting for this dataset since the day they assembled this land package. Unlike the previous focus on isolated occurrences, the company can now evaluate Magno as one connected mineral system, enabling the mapping of a broader mineral system. Market expectations suggest that this comprehensive dataset and the subsequent drill program will play a key role in unlocking the company's critical mineral potential. The company expects to provide additional technical updates, including interpreted QMAGT products, geological interpretations, and priority drill target generation, as final processing is completed and integrated into the 2026 exploration program.
