Goldhaven Advances Exploration with First Drill Hole Completed at Western Target, Copeçal Project
GOLDHAVEN ADVANCES EXPLORATION WITH FIRST DRILL HOLE COMPLETED AT
WESTERN TARGET, COPEÇAL PROJECT
Vancouver, BC – November 12th, 2025 – GoldHaven Resources Corp. (CSE: GOH | OTCQB:
GHVNF | Frankfurt: 4QS) (“GoldHaven” or the “Company”) is pleased to announce the
completion of its fifth diamond drill hole (CO -05) at the Copeçal Project, located in Mato
Grosso State, Brazil. Hole CO -05 represents the first test of the Western Target, following
the successful completion of four holes at the Eastern Target.
Highlights
• Fifth drill hole (CO-05) completed — first test of the Western Target at the Copeçal
Project, Mato Grosso, Brazil.
• 140 metres drilled intersecting a thick saprolite horizon (~50 m vertical) underlain
by sheared basement gneiss and muscovite schist , confirming structural
continuity across the property.
• Three additional holes planned in ongoing reconnaissance drilling to systematically
evaluate gold-in-soil and VLF-EM anomalies across the Eastern and Western Target
areas.
Hole CO-05 was designed to evaluate coincident geochemical and geophysical anomalies
interpreted to represent a continuation of the potentially mineralized structural corridor
observed to the east. The hole was completed to a downhole depth of 140 metres a nd
intersected a well -developed, clay-rich saprolite horizon from surface to approximately 60
metres downhole (equivalent to roughly 50 metres vertical depth). Beneath the saprolite,
drilling encountered competent bedrock composed of strongly sheared basem ent gneiss
and muscovite schist — lithologies consistent with those intersected in previous holes —
further supporting the interpretation of structural continuity across the project area.

The Company plans to complete an additional three holes as part of the ongoing
reconnaissance drill program at Copeçal. This phase is designed to systematically test
anomalous gold -in-soil and coincident very -low-frequency (VLF) electromagnetic
anomalies previously reported (see news release dated July 24 th, 2025). The program aims
to refine the understanding of subsurface geology, alteration, and the structural controls on
mineralization across both the Eastern and Western Targets.
Assay Results Pending
Analytical results for holes CO-01 and CO-02, drilled at the Eastern Target and disclosed in
the Company’s October 21s, 2025, news release, are expected within the next two weeks.
Results for holes CO -03 through CO -05 will be announced once received, validated, and
reviewed by GoldHaven’s technical team.
GoldHaven will continue advancing the program over the coming weeks, integrating
geological, structural, and geochemical data to refine targeting along both the East and
West anomalies. Assay results from the initial drill holes are expected in the near term.

Rob Birmingham, CEO of GoldHaven Resources, commented:
“The completion of Hole CO -05 marks an important milestone as we advance systematic
testing of the Copeçal targets. The identification of a thicker -than-anticipated saprolite
profile and the transition into sheared basement rocks provide key geological info rmation
for refining our exploration model. We look forward to the pending assay results from the
- 4 -
first two holes and to continuing our methodical approach to evaluating these priority
targets.”
About the Copeçal Gold Project: A Brief History
The Copeçal Gold Project is strategically situated within the Alta Floresta Gold Province, a
historically productive region that has yielded substantial gold discoveries since the late 1970s.
GoldHaven’ s tenements cover a total of 3,681 hectares in a geologically favourable setting within
the Juruena Gold Province of Brazil.

The Juruena Gold Province, also known as the Juruena Magmatic Arc, is an orogenic belt highly
prospective for mesothermal shear-related and intrusion-related gold deposits, such as G-Mining’s
Tocantinzinho deposit. Additionally, the region hosts recently i dentified porphyry -style deposits
- 5 -
(e.g., Serabi, Jaca) and epithermal -style deposits (e.g., X1, Aura). The presence of multiple deposit
styles, along with the confirmation of large -scale gold deposits in the Juruena Province of Brazil,
underscores the significant potential of the Copeçal Gold Project.
Recent exploration programs, including geochemical soil sampling, drone -mounted magnetometry
surveys, and historical drilling data, indicate the presence of multiple gold -bearing structures.
Notably, AngloGold Ashanti previously conducted systematic exploration on the property from 2010
to 2016, including auger and air -core drilling, geophysical surveys, and rock geochemistry,
identifying multiple zones of anomalous gold mineralization.
The Copeçal Gold Project benefits from extensive historical work, with AngloGold Ashanti’s
exploration confirming gold and arsenic anomalies, indicative of significant mineralization potential.
Soil sampling grids and follow -up auger drilling in key areas revealed consistent gold values over
wide zones, further supporting the presence of a substantial mineralized system.
About GoldHaven Resources Corp.
GoldHaven Resources Corp. is a Canadian junior exploration Company focused on acquiring and
exploring highly prospective land packages in North and South America. The Company’s projects
