GoldHaven Resources Provides Auger Drill Program Update at Copeçal Gold Project in Mato Grosso, Brazil
GoldHaven Resources Provides Auger Drill Program Update at Copeçal Gold
Project in Mato Grosso, Brazil
Vancouver, British Columbia – (GlobeNewswire) – June 26th, 2025, GoldHaven Resources Corp.
(“GoldHaven” or the “Company”) (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) is pleased to provide
an update on its systematic auger drill program over the east and west anomalies initiated on June 9th, 2025.
The Company’s geological team has successfully drilled past the half -way mark and the first round of
assays have been shipped to ALS Global Laboratory, with sample preparation being completed in Cuiaba,
and sample analysis being finalized in Belo Horizonte.
GoldHaven has now reached 70% of the planned program, successfully completing 1,400 meters and has
intersected regolith, weathering profile consistent with expectations at 0-20 meters depth. Additionally,
several holes show weathering down to 30 m eters in vertical depth which may indicate preferential
weathering along the major structures being targeted for potential mineralization.
GoldHaven has submitted a total of 350 samples from the East Target of its Copeçal Project to ALS Global
Laboratories for analysis. To ensure rigorous QA/QC protocols, sampling was conducted at consistent 2-
metre intervals down the drill hole. Quality control samples —including blanks, certifie d standards, and
duplicates—were inserted at a rate of 10% of the total sample batch. These QA/QC measures adhere to
industry best practices and align with the quality assurance standards of ALS Global Laboratories. As say
results are expected within approximately 3 to 4 weeks.
Rob Birmingham, CEO of GoldHaven Resources, commented: “We are excited to have surpassed the
first half of auger drilling on our Copeçal Gold project, with our first round of assays shipped for analysis.
The initial work has been focused on our east target, while we anticipate shifting to the west target in the
coming days which will give us more clarity on the anomalies prior to the initiation of diamond drilling.”
Auger Drilling and Electromagnetic VLF Survey Overview
The Auger Drilling Program is focused primarily on defining a 3D litho- geochemical footprint of gold
distribution within the regolith profile beneath the extensive East Gold -in-Soil Anomaly. Vertical auger
holes are being drilled systematically from surface to the regolith -bedrock interface—expected range is 5
to 30m in depth— on a tight 100m x 50m grid. This methodical approach is expected to generate high-
resolution data critical for the refinement of subsurface geological and structural models.

Looking ahead, GoldHaven anticipates launching a Drone -borne Very Low Frequency (VLF)
Electromagnetic Survey in July (referred to in Figure 2). This survey will target the structural trends
believed to be favourable hosts to gold mineralization, covering both the East and West Gold- in-Soil
anomalies as well as their potential strike extensions. The integration of VLF geophysics with auger
geochemistry will provide a robust framework for finalizing diamond drill collar locations, thereby
maximizing the efficiency and effectiveness of future drilling campaigns

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
- 4 -
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.
