GoldHaven Resources Confirms High-Grade Copper Mineralization at Three Guardsmen Project
GoldHaven Resources Confirms High-Grade Copper Mineralization at
Three Guardsmen Project
Vancouver, British Columbia – (GlobeNewswire) – December 9 th, 2025 - GoldHaven Resources
Corp. (“GoldHaven” or the “ Company”) (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) is pleased to
announce that assay results from the Three Guardsmen property have confirmed the presence of
high-grade surface copper mineralisation 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 including:
o J647161 (15.85% Cu)
o J647629 (12.75% Cu)
o J647753 (12.65 % Cu)
(Note - grab sample grades are not indicative of expected overall grades)
● 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.
Three Guardsmen:
The Three Guardsmen property comprises 14 contiguous mineral tenures covering 16,234 hectares
within the Atlin Mining Division of northwestern British Columbia. The claims are 100% owned by
GoldHaven Resources Corp. Strategically located near Haines Juncti on, 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
- 2 -
zones to bismuth, tellurium, and gold -rich areas, along with molybdenum in altered granites,
suggest a possible nearby porphyry system.

Table 1. Top 25 Copper Assays from 126 grab & chip samples from 2025 Field Program.
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.
Geological Significance:
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 k m 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.”
