GoldHaven Resources Completes Auger Drill Program at Copeçal Gold

Project in Mato Grosso, Brazil

Vancouver, British Columbia – (GlobeNewswire) – July 8 th, 2025, GoldHaven Resources Corp.

(“GoldHaven” or the “Company”) (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) is pleased to announce

completion of its initial Auger drill program at the Copeçal Project, Brazil which commenced on June 9th,

2025. A total of 107 auger holes were successfully drilled, delivering 2,153.4 metres of subsurface coverage

and marking a significant milestone in exploration efforts.

The Auger drill program included 92 Auger holes which systematically covered the main area of the east

anomaly on a 100m x 50m grid while a further 15 reconnaissance holes targeting geochemical – structural

targets projected towards the south-east from the western anomaly. Holes were drilled from surface to the

weathered rock (regolith) – fresh rock interface or to a maximum depth of 30m. The average hole depth

was 20.13 meters with the hole depth range of 2m – 30m.

A total of 1,325 samples, including QAQC samples, have been shipped to ALS Global Laboratories for

analysis. Sample preparation is being undertaken at ALS’s facility in Cuiabá, Brazil , with final low

detection fire assay analysis completed via their laboratory in Belo Horizonte , Brazil. To ensure rigorous

QA/QC protocols, sampling was conducted at consistent 2- metre intervals down the drill hole. Quality

control samples—including blanks, certified 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. Assay results are expected to be reported in late July or

early August.

Samples from the Auger program , which included soil – saprolite and remnant rock fragments were

geologically logged to inform the ongoing preparation of a 3D geological – lithogeochemical model for the

East Anomaly. Initial observations suggests that a reas where the depth to bedrock exceeds 20m reflect a

more pronounced, deeper regolith profile developed over potentially mineralized and hydrothermally

altered areas where the bedrock granite gneiss and schist has been more highly sheared and preferentially

weathered. These observations are supported by the presence of sericite alteration coincident with

disseminated limonitic boxwork (after pyrite) logged in samples collected from a number of the deeper

Auger holes.

Rob Birmingham, CEO of GoldHaven Resources, commented: “We are pleased to announce the

successful completion of our auger drilling program at the Copeçal Gold Project, with a total of 2,153.40

meters drilled. All assay samples have been shipped for analysis. While our initial efforts were focused on

the east target, we are particularly encouraged to have concluded the program by drilling the more

prominent anomaly on the west target. Our attention now turns to the upcoming Very Low Frequency (VLF)

electromagnetic geophysical survey, expected to commence mid -month, which will enhance our

understanding of the structures within the east and west targets, as well as highlight additional prospective

zones across the property.

VLF-EM Survey Overview

Looking ahead, GoldHaven anticipates launching a Drone -borne Very Low Frequency (VLF)

Electromagnetic Survey in July (referred to in Figure 4). This survey will target the structural trends

believed to be favorable hosts for gold mineralization , covering both the East and West Gold- in-Soil

anomalies as well as their potential strike extensions. The integration of VLF -EM 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

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.
