GoldHaven Resources Completes Summer Exploration Programs at Magno and Three Guardsmen Projects
GoldHaven Resources Completes Summer Exploration Programs at
Magno and Three Guardsmen Projects
Vancouver, British Columbia – (GlobeNewswire) – September 16th, 2025 - GoldHaven Resources
Corp. (“GoldHaven” or the “ Company”) (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) is pleased to
provide an update on its exploration work program on its 100% owned Magno and Three Guardsmen
Projects located in Northern British Columbia. The program was carried out by GoldHaven’s
experienced technical team under the supervision of Jean Paulter P.Geo.
Highlights:
• Magno and Three Guardsman successful completion of 2025 summer exploration
programs, collecting 354 and 126 samples respectively.
• Magno Project expanded by 5 .159.13 hectares through strategic staking to secure
coverage of the Cassiar Stock, believed to be related to mineralization.
• Exploration at Magno has confirmed the presence of high -potential, structurally
controlled skarn and CRD-style mineralization, drawing parallels to Coeur Mining Inc.’s
Silvertip Project.
• Three Guardsmen Project hosts high -grade Cu mineralization in epidote and magnetite
skarns, with extensive malachite -stained pods extending over a 1 km strike, and
geochemical pathfinders and textures suggesting a nearby intrusive source.
The field team has completed the 2025 exploration program, carrying out first-pass assessments at
both the Magno Property and the Three Guardsmen. A total of 354 rock samples were collected at
Magno, consisting primarily of grab samples along with chip and channel samples. At the Three
Guardsmen, the team collected an additional 126 grab and chip samples, providing a solid
foundation for advancing exploration on both properties.
Magno:
The Magno Project hosts multiple styles of mineralization that appear to share common fluid
pathways and heat sources, indicating a series of related mineralizing events. During the two -week
program at Magno, the team quickly recognized the significance of the Cassiar Stock — a 72 Ma
Cretaceous granite mapped within the eastern margin of the Cassiar Batholith. Originally described
by Panteleyev, detailed mapping by the team has confirmed a direct correlation between phases of
the Cassiar Stock (biotite quartz monzonite porphyry) and the property’s mineralized showings. As a

result, securing additional ground over the Cassiar Stock became an immediate priority, expanding
the Magno Project to 35,732.66 hectares.

By consolidating the Cassiar Stock and its associated mineralized showings into a single claim
package, GoldHaven’s technical team now has the rare advantage of interpreting the system as a
whole rather than in isolated pieces. Even after limited fieldwork, the team has been able to connect
mineralized skarns with north –south parallel contacts and crosscutting northeast -trending
structures, where narrow apophyses of Cretaceous Cassiar Stock quartz monzonite intrude the
surrounding Cassiar Terrane sediments.
Exploration at Magno Central (encompassing the Magno and D zones) has confirmed the presence
of structurally controlled skarn and CRD -style mineralization within the Lower Cambrian Atan
Group, specifically the Rosella Formation, which comprises limestone, marble, and clastic
limestones. Historically, these zones have been well known for Ag -Pb-Zn mineralization; however,

the team aims to expand on more recent discoveries indicating the presence of indium (In) and
gallium (Ga). Comparisons can be drawn to Coeur Mining Inc.’s Silvertip Project, located within the
same Cassiar Terrane north of the Magno property, which provides a strong analogue for the
potential development of deeper, contact-parallel, skarn systems at Magno and D.
Mapping and sampling in the W (Tungsten showings) of the Kuhn & Dead goat Zones of the Magno
property during the August field program focused on verifying historic trenches and conducting
detailed mapping of both the prospective area and the mineralogical zonation of the skarns. Skarn
mineral zonation is dominated by diopside –garnet assemblages, with additional zones containing
tremolite, pyrrhotite, and scheelite.
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.

geological area known for copper -magnetite skarns with 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, point to a possible nearby porphyry system.
At the Canadian Verdee and Mildred showings, high -grade copper occurs in concentrated pods
dominated by chalcocite and bornite, with secondary chalcopyrite and widespread malachite
staining. These mineralized zones, hosted in skarns, extend over a strike length of more than 1 k m,
highlighting the scale and potential of the system.

Situated within Late Cretaceous terranes known for world-class porphyry deposits such as Casino
and Red Mountain, the project offers significant exploration potential. GoldHaven’s strategy
leverages targeted geochemical and geophysical analysis to identify mineralized granitic intrusions
which may be the source of the promising skarn mineralization observed at surface.

Next Steps:
The team will be looking to get assays back within 6-8 weeks and will begin the next phase of
exploration through geochemical analysis, interpretation as well as continuing the large task of data
compilation. Historically on Magno there exists data for nearly 11,000 meters of drill core across the
property. The team has been continuing its efforts to digitize the data and plan to model all the
historical work over the winter combined with its 2025 field work to plan for the next steps in
exploration.
Rob Birmingham, CEO of GoldHaven Resources, commented: “We are extremely pleased with
the successful completion of our 2025 summer exploration programs at Magno and Three
Guardsmen. The team’s work has not only expanded the Magno Project by over 5,000 hectares to
consolidate the Cassiar Stock but also confirmed the presence of high -potential skarn and CRD -
style mineralization with strong analogues to Coeur Mining’s Silvertip Project. At Three Guardsmen,
our field program highlighted high-grade copper mineralization extending over a kilometer of strike,
with evidence pointing to a nearby porphyry system. These results validate our exploration strategy
and provide an exciting foundation for advancing both projects toward their full potential.
