Advances Copeçal Gold Project
GoldHaven Advances Copeçal Gold Project Following Initial Drilling;
Phase 2 Program Planned at West Target
Vancouver, British Columbia – March 17th, 2026 – GoldHaven Resources Corp.
(“GoldHaven” or the “Company”) is pleased to provide an exploration update and outline its
forward exploration strategy following completion of the Company’s inaugural diamond
drilling program at the Copeçal Gold Project in Mato Grosso State, Brazil.
Highlights:
• First-ever diamond drilling program completed at Copeçal, marking a major
milestone in advancing the project from surface exploration toward subsurface
discovery.
• Gold and copper anomalism intersected in drilling, accompanied by structural
features and phyllic alteration consistent with a mineralized hydrothermal system.
• West Target emerges as the most promising zone, demonstrating widespread gold
anomalism within both saprolite and underlying bedrock and forming the focus of
planned Phase 2 drilling.
• Project supported by extensive historical exploration by AngloGold Ashanti, providing
a strong technical foundation including geochemical, geophysical, and geological
datasets now being integrated with new drilling results.
• Phase 2 drill program planned for mid -Q2 2026, aimed at expanding mineralization
and vectoring toward higher-grade zones at the West Target.
“Completing the first diamond drilling program at Copeçal marks an important milestone as
we transition the project from surface exploration into systematic drill testing,” said Rob
Birmingham, President & CEO of GoldHaven. “While this initial phase was designed as a
first-pass program, the presence of gold and copper anomalism together with structural
deformation, alteration, and quartz veining provides strong geological indicators that we are
operating within a mineralized system. The West Target in parti cular has emerged as a
priority area where Phase 2 drilling will focus on expanding the system and vectoring toward
higher-grade zones. With the benefit of new drill data combined with historical exploration
work completed by AngloGold Ashanti, we believe the upcoming phase of exploration will
significantly enhance our ability to target the core of the system.”

Exploration Program Summary
The Company completed nine diamond drill holes during the inaugural drill campaign at
Copeçal, representing the first -ever drilling program conducted on the property. The
program tested two priority exploration areas referred to as the West Target and the East
Target.
Drilling successfully confirmed the presence of anomalous gold and copper
mineralization, as well as structural deformation, quartz veining, and phyllic alteration
consistent with hydrothermal mineralizing systems common to the region. These geological
indicators support GoldHaven’s working model that the Copeçal Project may host a broader
mineralized system and that the initial drilling campaign represents an important first step
in vectoring toward higher-grade zones.
The Company believes the results from this initial program provide valuable technical
information that will significantly refine exploration targeting as the project advances to its
next phase.

West Target – Priority Area for Phase 2 Drilling
Results from the West Target were the most encouraging from the program, with more
consistent and widespread gold anomalism encountered in both saprolite and underlying
bedrock.
Drill holes targeting this area intersected a substantially thicker saprolite profile extending
to approximately 60 metres downhole, which may reflect preferential weathering
associated with structurally controlled alteration zones.
Within the underlying granodiorite–gneiss host rocks, geological logging identified:
• Multiple phases of shearing and deformation
• Quartz veining and sheeted veinlets
• Structural fabrics consistent with potential fluid pathways
• Alteration patterns typical of mineralized hydrothermal systems
These features collectively support the interpretation that the West Target may represent a
larger mineralized corridor and will be the primary focus of the Company’s planned Phase 2
drill program.

West Target drilling.)

East Target
At the East Target, drilling intersected coincident gold and copper anomalism
accompanied by phyllic alteration and structural features consistent with intrusion-related
systems.
While encouraging, the geological interpretation suggests that the initial drill holes may
have intersected a more distal portion of the mineralized system, indicating that
stronger mineralization may occur elsewhere within the broader target area.
Further geological interpretation and targeting work is underway to evaluate follow-up
exploration opportunities within this zone.

East Target drilling.)

Next Phase of Exploration
GoldHaven has initiated a comprehensive technical review integrating the new drill data
with historical exploration datasets generated by AngloGold Ashanti, including
geochemical, structural, and geophysical data.
This integrated interpretation will focus on refining the geological model and generating
additional high-priority drill targets.
Key components of the ongoing technical work include:
- 5 -
• Detailed multi-element geochemical interpretation
• Structural analysis of mineralization controls observed in drill core
• Alteration mineral characterization
• Reinterpretation of historical geophysical datasets
• Physical property testing of drill core including resistivity and conductivity
measurements
These datasets will be used to refine drill targeting for a Phase 2 drilling program currently
anticipated to commence by mid-Q2 2026, with an initial focus on expanding mineralization
and testing potential higher-grade zones at the West Target.
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
(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.
