GoldHaven Resources Mobilizes Drill Contractor to Copeçal Gold
Project, Mato Grosso, Brazil
--Maiden Diamond Drill Program to Test High-Priority Gold Targets--
Vancouver, BC, September 24th, 2025 – GoldHaven Resources Corp. (CSE: GOH | OTCQB:
GHVNF) (“GoldHaven” or the “Company”) is pleased to announce that the drill contractor
has mobilized to site to commence the Company’s maiden diamond drilling program (see
previous press release dated 09/09/2025) at the Copeçal Gold Project in Mato Grosso State,
Brazil.
This marks a major milestone for GoldHaven as it transitions from early-stage exploration to
targeted drilling on high -priority gold anomalies, following months of systematic
groundwork.
Investment Highlights:
• Drill-Ready Project in a Tier-1 Jurisdiction
Copeçal is located in the Juruena Gold Belt, one of Brazil’s most prospective but
underexplored regions. The project comprises 3,681 hectares, 100% owned by
GoldHaven, and includes ground previously explored by AngloGold Ashanti.
• Compelling Targets Defined
Two large-scale soil anomalies (“East” and “West”) , each with 3 km strike lengths ,
have been delineated. These anomalies align with a major regional scale shear zone,
often a hallmark of the orogenic gold systems targeted by the company.
Auger drilling (107 holes), a VLF-EM geophysical survey and historical data generated
by prior exploration phases (Boa Gold, AngloGold Ashanti) have confirmed structural
controls and helped pinpoint diamond drill locations.
• Strong Technical Rationale
The drill program aims to intersect primary bedrock with the targeted gold
mineralization beneath the strongest geochemical anomalies. Results from the
auger program and ongoing geophysics have significantly de-risked this phase.

“This is a key value-creation moment for GoldHaven,” stated Rob Birmingham, CEO. “We’ve
built a strong technical foundation and are now able to drill -test our priority targets
associated with consistent gold-in-soil anomalies linked to robust geological structures
defined by our geophysical programs . With drilling almost underway, we are entering a
phase of potentially significant discovery upside”.

Copeçal Gold Project Drill Targets:
GoldHaven has identified two high -priority drill targets, East and West, for its upcoming
diamond drilling program. The program will consist of a total of 1200m of diamond drilling
with 5-6 angled NQ holes up to 150m deep at both 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 fav ourable 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.
