VANCOUVER, British Columbia — January 6, 2026 — Leads & Copy — GoldHaven Resources Corp. has announced preliminary assay results from its 2025 surface exploration program at the Magno Property in northwestern British Columbia, confirming high-grade silver, lead, zinc, tungsten, and critical-mineral mineralization across multiple zones.
The results, derived from both historical and newly defined showings, reinforce Magno’s potential as a district-scale polymetallic system, according to the company.
Notable assay results include silver values up to 2,370 g/t Ag, lead exceeding 20% Pb, zinc values up to 19.25% Zn, tungsten values up to 6,550 ppm W, and indium values up to 334 ppm In, returned from surface sampling across the property.
Highlights from the exploration program include:
High-grade silver-lead-zinc mineralization confirmed, with grab samples returning up to 2,370 g/t Ag, >20% Pb, and 19.25 % Zn from the Magno and D Zones.
Widespread anomalous silver values, with 45 of 357 samples returning >100 g/t Ag.
Strong tungsten results, including 32 samples >1,000 ppm W and a maximum value of 6,550 ppm W from the Vines Lake occurrence.
Consistent tungsten mineralization confirmed at the Kuhn and Dead Goat Zones, with multiple samples ranging from 500 to 5,000 ppm W and an anomalous population exceeding 0.2% W.
Critical mineral potential demonstrated, with indium values up to 334 ppm In associated with Sphalerite (Zn).
Verification of multiple historical showings and identification of new targets across the property.
Recognition of geochemical zoning consistent with a large, intrusive-related mineral system.
The 2025 program was designed to systematically verify historical mineral occurrences and expand the geochemical database across the Company’s 36,973.29-hectare land package. A total of 357 rock samples were collected and analyzed using an expanded, modern analytical suite to better characterize the property’s complex polymetallic zoning.
Robert Birmingham, President and CEO of GoldHaven Resources Corp., stated that the results represent a major step forward in validating the Magno Property as a large, zoned polymetallic system. He noted that the confirmation of high-grade silver-lead-zinc mineralization at surface, together with strong geochemical zoning and structural controls, mirrors many of the key characteristics observed at Coeur Mining’s nearby Silvertip Mine.
Birmingham also highlighted the extensive tungsten mineralization across multiple zones as a compelling and differentiated critical-metals component not present at Silvertip.
According to the company, the return of assay results has successfully achieved the primary objective of the 2025 field program: validating historical surface results and expanding upon them using a modern, multi-element, and multi method analytical approach.
GoldHaven said all samples were analyzed using both a 52-element ICP-MS method and lithium borate fusion, allowing for improved detection of precious metals, base metals, tungsten, and critical minerals across varying lithologies and alteration styles.
Results from the Magno and D Zones reinforce the possibility that they are part of a larger, laterally extensive silver-lead-zinc system. The multi-element assay data also identified a number of samples with anomalous Au-Bi-Te, possibly indicative of zoning commonly observed in intrusive-related systems.
At the Kuhn and Dead Goat Zones, tungsten assays are consistent with historical results, with multiple samples returning values between 500 and 5,000 ppm W. The Kuhn Target now demonstrates approximately 1.3 kilometres of anomalous tungsten mineralization along strike.
The results from the 2025 program significantly enhance GoldHaven’s confidence in the Magno Property. The Company will now advance prioritized targets—including the Magno and D Zones, the Kuhn and Dead Goat tungsten areas, and the newly defined Vines Lake showing—toward detailed targeting and future drill planning.
The Magno Project is a district-scale exploration asset spanning 36,973.29 hectares across the Cassiar region of northwestern British Columbia. The project directly borders mineral claims held by Cassiar Gold Corp. and Coeur Mining Inc.
