Vancouver, British Columbia, January 6th, 2026 – GoldHaven Resources Corp. ("GoldHaven" or the "Company") (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) is pleased to announce preliminary assay results from its 2025 surface exploration program at the Magno Property, located in northwestern British Columbia. Results confirm high-grade silver, lead, zinc, tungsten, and critical-mineral mineralization across multiple zones, including historical and newly defined showings, reinforcing Magno’s potential as a district-scale polymetallic system.
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:
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.

With the return of assay results, the Company 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. Given the size of the property and the presence of multiple mineralization styles, 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. This approach proved particularly effective in refining the distribution and continuity of tungsten mineralization.
Results from the Magno and D Zones reinforce the possibility that they are part of a larger, laterally extensive silver-lead-zinc system. While historically interpreted as classic Carbonate Replacement Deposits (CRDs), both zones also display characteristics consistent with structurally controlled hydrothermal mineralization. The confirmation of grade continuity across significant strike lengths and elevation, together with observed geochemical zoning, suggests the Magno and D Zones may represent the surface expressions of a more extensive mineralized 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. One sample (J647437) returned >25 ppm Au, accompanied by elevated bismuth (Bi) and tellurium (Te). A subset of samples exhibiting Au-Bi-Te signatures will be re-assayed using analytical methods better suited to low-level gold detection.
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, supporting continued de-risking through follow-up mapping and sampling.
The results from the 2025 program significantly enhance GoldHaven’s confidence in the Magno Property as a robust, district-scale polymetallic system with strong silver, base-metal, tungsten, and critical-mineral potential. 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.
“These results represent a major step forward in validating the Magno Property as a large, zoned polymetallic system,” said Robert Birmingham, President and CEO of GoldHaven Resources Corp. “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, which serves as an important analogue for the silver-rich CRD mineralization at Magno. In contrast, the extensive tungsten mineralization we are seeing across multiple zones highlights a compelling and differentiated critical-metals component that is not present at Silvertip. While Magno remains an early-stage project, the scale, metal associations, and geological architecture support our view that this district has the potential to host a much larger, intrusion-related mineral system.”
“Importantly, our 2025 program successfully verified historical grades and expanded the geochemical dataset using modern analytical techniques, allowing us to confidently prioritize targets such as the Magno and D Zones, Kuhn, Dead Goat, and Vines Lake as we advance toward detailed targeting and future drill planning.”
Magno Project:
GoldHaven Resources’ Magno Project is a district-scale exploration asset spanning 36,973.29 hectares across the prolific Cassiar region of northwestern British Columbia. Located just three kilometres south of the historic mining town of Cassiar and crossed by Highway 37, Magno benefits from road access and infrastructure rarely matched by early-stage exploration projects of this scale.
The project directly borders mineral claims held by Cassiar Gold Corp. and Coeur Mining Inc., positioning GoldHaven within a proven regional mining corridor with established operators active in both precious metal and polymetallic systems. Proximity to supply hubs such as Dease Lake, Watson Lake, and Whitehorse — along with potential hydroelectric access from regional infrastructure — enhances Magno’s logistical and long-term development advantages.
