VANCOUVER, British Columbia, Aug. 21, 2025 (GLOBE NEWSWIRE) -- GoldHaven Resources Corp. ("GoldHaven" or the "Company") (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) is pleased to announce it has mobilized its geological team and has begun its exploration efforts across the 100%-owned Magno and Three Guardsman projects, located in Northern British Columbia.
GoldHaven’s fully funded 2025 exploration program is set to advance its highly prospective assets, the Magno and Three Guardsman projects. At the Magno Project, systematic sampling and structural mapping will target skarn and replacement-style mineralization with the goal of vectoring toward a potential porphyry source linked to the Cassiar Batholith. Meanwhile, at the Three Guardsmen Project, the team will build on 2024 results that outlined classic porphyry-style alteration zonation within granitic units—considered strong supporting evidence for the existence of a large-scale mineralized system at depth. Together, these programs provide multiple opportunities to further develop and expand the projects knowledge leading towards our goal of a 2026 drill campaign.
Magno Project
The Company holds 100% ownership of the Magno mineral claims in British Columbia. The Project spans 30,573.53 hectares and is situated within the historically rich Liard Mining Division. The Project is accessible via Highway 37, which crosses the southeastern claim area, providing good access for future exploration and development work.
The Magno Project hosts several critical metals, including tin (Sn), indium (In), zinc (Zn), silver (Ag) gold (Au), tungsten (W), and gallium (Ga) which are essential for various industries, including electronics, defense, batteries, and green energy technologies. Additionally, the Project hosts several different styles of base metal (zinc-lead) mineralization, including skarn and carbonate replacement styles along with potential for deeper porphyry-associated copper-molybdenum-tin mineralization. GoldHaven is looking to apply new geological research to potentially overlooked areas to analyze a broad range of metals and use as vectors to potential porphyry mineralization.

Magno Exploration Program:
GoldHaven will field a ten-person geological team for its 2025 program, based in a fully serviced multi-room facility in the Cassiar area, providing close access to the Project. Working in two-person crews, the team will systematically cover the more than 30-kilometre north–south strike length of the Cassiar Terrane. The program is designed to identify and sample widespread skarn and replacement-style mineralization, with a particular focus on geochemical zonation and mappable geothermal gradients that may provide vectors toward deeper mineralizing systems.
The Cassiar Terrane hosts several of the Magno property’s key mineralized showings, where sampling has returned significant values including 110 to 1,749 ppm tin and up to 5.58% zinc (Johnston, 2024). Historical work by Eveready (2003) further highlighted the property’s potential, reporting grades of 6.2% Zn, 28.2% Pb and 820 g/t Ag over 1.2 metres. Priority exploration areas include the Magno, Middle and Upper D, Kuhn, and Dead Goat zones. Geologically, the Cassiar Terrane overlies the Cretaceous-age Cassiar Batholith—a biotite- and hornblende-bearing granite intrusive interpreted as a potential driver for the region’s mineralizing fluids.
This work will provide two major benefits. First, it will advance GoldHaven’s understanding of the distribution and genesis of critical metals such as indium, gallium, and germanium, along with silver, zinc, and lead replacement-style targets within the Cassiar Terrane. The presence and zonation of these metals within skarn systems are often directly linked to the larger magmatic-hydrothermal processes responsible for porphyry development. Second, the resulting geochemical data will help refine and prioritize targets for future geophysical surveys—vectoring exploration toward porphyry-style mineralization within the Cassiar Batholith, where the ultimate prize is the discovery of a gold- and copper-rich system at depth.
Data generated from this geochemical program, when integrated with detailed structural mapping, will support vectoring toward potential fluid pathways emanating from the Cassiar Batholith—which may host a buried porphyry system.

Three Guardsman Project
The Three Guardsmen property comprises 14 contiguous mineral tenures covering 16,234 hectares within the Atlin Mining Division of northwestern British Columbia. The Company holds 100% ownership of the Three Guardsman mineral claims which are strategically located near Haines Junction.

The Guardsmen Project sits within a geologically prospective terrane known to host copper- and gold-bearing skarn mineralization, as well as polymetallic systems. Historical exploration across the property has identified copper, gold, silver, molybdenum, zinc, and magnetite mineralization across multiple showings. Notably, transitions from Cu/Ag-rich zones to Bi/Te/Au-rich domains suggest analogues to Hedley-style skarns, with potential for distal, gold-enriched systems—key exploration targets moving forward.
The project is situated within Late Cretaceous terrane known to host significant porphyry deposits such as Casino and Red Mountain. GoldHaven’s exploration strategy focuses on geochemical and geophysical surveys aimed at identifying granitic intrusions that may represent the porphyry sources associated with the skarn mineralization observed at surface.
Three Guardsman Exploration Program:
Following the completion of the 2–3-week Magno field program, GoldHaven’s exploration team will mobilize through Whitehorse on route to the Three Guardsmen Project, where a 10-day exploration campaign is planned.
The team will build on the 2024 exploration work at the Three Guardsmen Project, which included localized geological mapping and systematic rock sampling on a grid. That program successfully identified classic porphyry-style alteration zonation—particularly within the granitic units underlying mineralized skarn horizons. These patterns are considered strong indicators of a potential porphyry source at depth.
Drawing on techniques and insights developed during the establishment of the Magno program, the team aims to expand mapping efforts across the Three Guardsmen property, with a focus on further delineating propylitic, phyllic, and potassic alteration zones identified in the previous season. This integrated approach will help refine priority target areas for future drilling.
GoldHaven’s technical team will be advancing the Three Guardsmen Project toward the first phase of systematic exploration, focused on testing these high-priority porphyry and skarn targets. Alongside Magno, the project is positioning itself as a compelling and underexplored opportunity in the search for critical, strategic and base metals.
"We are excited to launch our summer work programs at the Magno and Three Guardsman Projects in northern British Columbia—two highly prospective assets in our portfolio. Leveraging results from prior exploration and the recently completed comprehensive data compilation over both projects, our technical team has targeted key areas of focus with strong mineralization potential. The program will be led in the field by Company Director Gerry Diakow, with Michael Garagan serving as Technical Lead, and Jean Pautler as P. Geo to ensure disciplined execution and geological oversight throughout the campaign" – Rob Birmingham, CEO of GoldHaven Resources Corp.
