GoldHaven Mobilizes Exploration at Copeçal Gold Project in Brazil

Vancouver, British Columbia, March 25, 2025 – GoldHaven Resources Corp. ("GoldHaven" or the

"Company") (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) is pleased to announce the engagement of

Gustavo Rosa de Almeida (M.Sc.) as the local project geologist responsible for coordinating the

mobilization efforts in Brazil for the upcoming exploration program at the Copeçal Gold Project in Mato

Grosso.

Mr. Almeida is a high caliber Brazilian Exploration Geologist with 10 years of experience covering a wide

range of commodities and geological terranes throughout Brazil. He has a broad set of skills and experience

including all phases of exploration from target generation to drill evaluation and specializes in the

integration and interpretation of structural, geophysical and geochemical datasets through the complete

exploration cycle. Importantly in this new role at Copeçal he has considerable highly relevant regional and

local experience having recently explored over several years of Au-Cu porphyry/Orogenic systems in the

Juruena-Teles Pires Polymetallic Province with successful company´s such as Bemisa and Aura Gold.

As part of preparations to mobilize the exploration team to the project, the Company has commenced

stakeholder engagement and permitting activities in anticipation of initial “on the ground” work during the

next 4-6 weeks. Initial activities will focus on establishing local logistic support and accommodation, hiring

sampling crews, and preparing necessary access and communications systems. It is anticipated that the

initial Auger Litho-geochemical drilling program will commence in Q2 2025.

At Copeçal, two principal, priority targets, namely the East and West targets are defined as two significant

gold in soil anomalies, both extending over ~3km of strike on the property linked by a major shear structure.

These soil anomalies are considered to reflect an in-situ bedrock source for gold based on wide spaced,

shallow hand auger drilling completed by AngloGold Ashanti. Initial exploration activities at Copeçal by

Goldhaven are aimed at better defining the detailed geometry of these anomalies by systematically testing

the extent from surface to bedrock and laterally. It is envisaged that the Auger drilling will allow a robust

litho-geochemical anomaly to be generated from which focused diamond drilling may be targeted to

intersect mineralization expected at depth.

Grid (black dots) and VLF Drone Magnetics (Red flight plan polygons)

The Company is planning 2,000m of Auger drilling for the East Target. This drilling will be undertaken

using a truck mounted motorized Auger (see figure 2) on a regular grid with holes spaced 50m and 100m

apart along lines spaced at 200m intervals along strike. Holes will be drilled to intersect the full – oxidized

and weathered regolith profile from surface to hard bedrock (refusal) which is expected to range from 10-

25m in thickness. Samples will be collected at 1m intervals down the hole from which composite samples

for chemical analysis will be prepared.

It is anticipated that a further 2,000m of Auger drilling will be undertaken over the West Target following

the completion of the East Target drilling, subject to permitting.

In addition to the Auger drilling, the Company will be concurrently undertaking surface geological and

structural mapping as well as a VLF* Drone survey across the property to add further important structural

and geological data, which when combined with the 3D Litho-geochemical model will greatly support the

all-important diamond drill targeting phases anticipated to begin in Q3 2025.

*VLF - Very Low Frequency is a method to measure conductivity and resistivity in rocks. Mineralized zones usually

show silica enrichment (high resistivity) or sulfidation (conductivity). The method can detect anomalies of massive

and disseminated zones of metallic minerals.

Figure 3: Schematic of the envisaged regolith profile at Copeçal (East and West Targets) that will be sampled by the

upcoming Auger Drilling Program

As mentioned above prior handheld (Trado) Auger drilling completed over the East and West targets

generated geochemical data confirming that the gold in soil anomalism defined at surface was in-situ (not

transported) and that a bedrock source for this gold was likely present at depth. However, this sampling did

not completely or adequately sample the full regolith profile or produce sufficient sample volumes to allow

the development of a complete 3D litho-geochemical model of the gold dispersion in the regolith from

which to confidently define targets for diamond drilling. The Auger drilling planned for both the East and

West targets will now allow for the preparation of a full 3D geometrical representation of the gold

distribution in the regolith profiles from surface to bedrock as represented in figure 2.

All historical data completed over the Copeçal Project by AngloGold Ashanti, including soil and hand-

auger geochemical sampling, drone Magnetic and trial Induced Polarization (IP) geophysical data has been

compiled into a 3D project model which is being used by the GoldHaven Geological Team to plan the

upcoming exploration phases (Auger drilling, detailed VLF Drone geophysics and geological mapping will,

over the coming months lead to the definition of diamond drilling 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 identified 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.
