GoldHaven Resources verifies high-grade copper mineralization at Three Guardsmen Project, British Columbia

GoldHaven Resources Corp. [CSE: GOH; OTCQB: GHVNF; FSE: 4QS] reported that assay results from the Three Guardsmen property have confirmed the presence of high-grade surface copper mineralization on its 100%-owned property located in northern British Columbia.

Highlights: 126 surface rock samples collected, including 25 samples exceeding 10,000 ppm (1% Cu). High-grade grab samples included sample J647161 (15.85% Cu); J647629 (12.75% Cu) and J647753 (12.65 % Cu).

The Three Guardsmen Project hosts high-grade copper mineralization in epidote–magnetite skarns, with extensive malachite-stained pods traced over more than 1 km of strike.

Porphyritic intrusive textures with associated elevated Cu and Mo values have been identified at low elevations in the valley bottom, possibly indicative of an intrusive source for the skarn mineralization.

Geochemical transitions across the property (Cu–Ag → Bi–Te–Au → Mo) suggest a vector towards an intrusive heat source underlying the skarn system.

The Three Guardsmen property comprises 14 contiguous mineral tenures covering 16,234 hectares within the Atlin Mining Division of northwestern British Columbia.

Strategically located near Haines Junction, the Three Guardsmen Project sits in a highly prospective geological area known for copper-magnetite skarns with associated gold and molybdenum mineralization. Observed transitions from copper- and silver-rich zones to bismuth, tellurium, and gold-rich areas, along with molybdenum in altered granites, suggest a possible nearby porphyry system.

The 2025 field program at Three Guardsmen concentrated on verifying historical high-grade copper samples located at the Canadian Verdee and Mildred showings as well as doing first pass mapping and assessment on the property.

Assay results successfully validated historical sampling, returning new discoveries that include copper grades up to 15.85% Cu (Sample J647161). Of the 126 samples collected, 25 returned assays above 1% Cu, confirming the widespread distribution of mineralization across the property.

At the Canadian Verdee high-grade copper occurs in local pods dominated by bornite and chalcocite. These grade along strike into more extensive epidote-dominant skarn with magnetite-chalcopyrite mineralization and widespread malachite staining.

These mineralized zones extend over a strike length of more than 1 km, highlighting the scale and potential of the system. The team believes the skarn zones may extend from Canadian Verdee to Mildred for a total of 2.6 km of prospective strike length; cliff side oxidization suggests this is likely, although rugged terrain currently has prevented verification of this.

Importantly, the presence of altered granites carrying molybdenum—along with systematic geochemical transitions from Cu-Ag zones into Bi-Te-Au enrichment—suggests the presence of a nearby porphyry intrusion driving the metal system.

The project lies within a Late Cretaceous tectonic setting that hosts several world-class porphyry deposits, including Casino and Red Mountain, further underscoring the exploration potential.

GoldHaven’s ongoing exploration strategy includes targeted geochemical surveys, structural mapping, and geophysical interpretation aimed at defining potential mineralized granitic intrusive centres.

Rob Birmingham, CEO of GoldHaven Resources, commented: “These assays are a major milestone for GoldHaven. Discovering copper grades as high as 15.85% at surface, along with widespread high-grade mineralization across the property, clearly shows the strength of the system at Three Guardsmen. This is the kind of early success that can redefine a company. With strong geological evidence pointing toward a nearby porphyry source, we believe the project offers exceptional upside as we continue to advance exploration.”

GoldHaven Resources is focused on acquiring and exploring prospective land packages in North and South America. The ompany’s projects include the flagship Magno Project, a district-scale polymetallic property adjacent to the historic Cassiar mining district in British Columbia; the Three Guardsman Project, which exhibits significant potential for copper and gold-skarn mineralization; the Copeçal Gold Project, a drill-ready gold project located in Mato Grosso, Brazil with a 6km strike of anomalous gold in soil samples; and three critical mineral projects with extensive tenement packages totaling 123,900 hectares: Bahia South, Bahia North and Iguatu projects located in Brazil.
