GoldHaven Resources Provides Exploration Update on Magno Project
GoldHaven Resources Provides Exploration Update on Magno Project
Vancouver, British Columbia – (GlobeNewswire) – September 4th, 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 the 100% owned Magno Project located in
Northern British Columbia.
Highlights
• The Magno Project field program is halfway complete, with systematic sampling and detailed
mapping advancing understanding of larger, deeper targets linked to Cretaceous
magmatism and extensive surface skarn mineralization.
• The project features multiple mineralization styles sharing common fluid pathways, enabling
a holistic interpretation of the consolidated Cassiar Stock system, including connections
between mineralized skarns and intrusive structures.
• At the Magno and D zones, structurally controlled skarn and CRD -style mineralization with
high-grade Ag -Pb-Zn (exceeding 2,000 ppm Ag) has been confirmed, alongside emerging
indium and gallium potential, drawing similarities to Coeur Mining's Silvertip Project.
• Mapping at the Kuhn and Dead Goat zones has delineated skarn horizons with potential for
up to 2 km strike extensions, featuring diopside -garnet assemblages, scheelite, and
crosscutting structures indicating broader exploration upside.
Magno Summer 2025 Field Program
GoldHaven’s fully funded 2025 exploration program has passed the halfway mark, with the team
making strong progress through systematic sampling and detailed structural and mineralization
mapping. The program is designed to advance the Company’s understanding of the potential for
larger and deeper targets linked to the Cretaceous magmatism, while also evaluating the extensive
surface skarn and carbonate replacement-style mineralization across the project. Initial samples
are being prepared for shipment to ALS Global in Whitehorse, Yukon. The results are expected to
provide important catalysts and direction for advancing the Magno Project.
The Magno Project hosts multiple styles of mineralization that appear to share common fluid
pathways and heat sources, reflecting a series of related mineralizing events. 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
- 2 -
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 age Cassiar Stock intrude the surrounding Cassiar Terrane sediments.
A portion of the team’s work has been directed toward confirmation sampling, including high-grade
surface samples along with historic trench and chip sample intercepts. These efforts were further
advanced through the addition of new extensions to historic chip and channel samples,
concentrated in areas of known mineralization such as the Magno and Kuhn zones, where historical
resource estimates have been reported by previous operators.
Magno and D Zones
Exploration at Magno Central (encompassing the Magno and D zones) has confirmed the presence
of structurally controlled skarn and CRD -style mineralization as well as some unique and poorly
exposed hydrothermal minerali zation 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 pre sence of indium (In) and gallium (Ga). Mineralization is
characterized by sulphur- rich, redox -driven skarns hosting massive galena with associated
sphalerite and magnetite. Both historical sampling and recent sampling by James Turner P.Geo has
verified high silver values from these structurally controlled skarns exceeding 2,000 ppm Ag from
galena-dominated zones.

At both the Magno zones, mineralization is structurally controlled, occurring as bedding -parallel,
conformable “manto” bodies as well as crosscutting “chimney”-style mineralization, with an overall
northeast trend cutting through the Rosella Group limestones. 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, large-
scale skarn systems at Magno. The D zone uniquely shares analogies with the Magno but additionally
contains some impressive zones of massive sulphides which carry textural similarities to
hydrothermal mineralization. More work is required to understand the D zone in greater detail, but
its presence suggests a larger, longer-lasting, multiphase and potentially multi-deposit style district
within Magno than previously imagined.
Kuhn and Dead Goat:
Mapping and sampling in the Kuhn Zone 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. Two principal skarn horizons, the Lower and Upper 3a skarns, have been
delineated, traced for 640 m and 206 m respectively, with the potential to extend along strike for up
to 2 km each. The Lower 3a skarn, generally well exposed, follows the Boya–Rosella Group contact,
while the Upper 3a skarn lies 10–20 m stratigraphically above and is more poorly exposed.
Skarn mineral zonation is dominated by diopside –garnet assemblages, with additional zones
containing tremolite, pyrrhotite, and scheelite. The skarns pinch and swell along strike, with variable
widths. Historical reports document scheelite mineralization in zones 1–4 m wide; however, visible
scheelite has also been observed in quartzites adjacent to the contact, suggesting potential for
increased widths and further exploration upside.
At Kuhn South, the same skarn horizons are present but are crosscut by a northeast- trending
structure. Here, skarn mineralization is oriented NE, characterized by a silicified diopside –garnet
core with pervasive sphalerite banding.
Similar mineralization is present at the Dead Goat showing, a north–south striking skarn composed
of diopside, garnet, pyrrhotite, and scheelite, ranging from 1 m to several m in width, with a surface
expression of up to 200 m.

Rob Birmingham, CEO of GoldHaven Resources, commented: “ We are pleased to provide an
update on the exploration program at the Magno Project, which commenced in August and has
already delivered encouraging progress. The program has focused on validating historical high-grade
mineralization, with the team success fully accessing a significant portion of the expansive 30,000 -
hectare property. Numerous rock and chip samples have been collected and will be submitted for
analysis upon program completion. The Project benefits from established road access and excellent
on-site accommodations —remnants of past mining activity in and around Magno —allowing the
team to operate efficiently and maximize productive time in the field. Our dedicated team is on track
with detailed structural mapping and sampling, paving the way to delineate the deeper- rooted
systems and unlock the full polymetallic potential of this expansive property.”
