GoldHaven Resources Corp. (CSE: GOH,OTC:GHVNF | OTCQB: GHVNF | Frankfurt: 4QS) ("GoldHaven" or the "Company") is pleased to announce the completion of its fifth diamond drill hole (CO-05) at the Copeçal Project, located in Mato Grosso State, Brazil. Hole CO-05 represents the first test of the Western Target, following the successful completion of four holes at the Eastern Target.
Highlights
- Fifth drill hole (CO-05) completed — first test of the Western Target at the Copeçal Project, Mato Grosso, Brazil.
- 140 metres drilled intersecting a thick saprolite horizon (~50 m vertical) underlain by sheared basement gneiss and muscovite schist , confirming structural continuity across the property.
- Three additional holes planned in ongoing reconnaissance drilling to systematically evaluate gold-in-soil and VLF-EM anomalies across the Eastern and Western Target areas.
Hole CO-05 was designed to evaluate coincident geochemical and geophysical anomalies interpreted to represent a continuation of the potentially mineralized structural corridor observed to the east. The hole was completed to a downhole depth of 140 metres and intersected a well-developed, clay-rich saprolite horizon from surface to approximately 60 metres downhole (equivalent to roughly 50 metres vertical depth). Beneath the saprolite, drilling encountered competent bedrock composed of strongly sheared basement gneiss and muscovite schist — lithologies consistent with those intersected in previous holes — further supporting the interpretation of structural continuity across the project area.

The Company plans to complete an additional three holes as part of the ongoing reconnaissance drill program at Copeçal. This phase is designed to systematically test anomalous gold-in-soil and coincident very-low-frequency (VLF) electromagnetic anomalies previously reported (see news release dated July 24 th , 2025). The program aims to refine the understanding of subsurface geology, alteration, and the structural controls on mineralization across both the Eastern and Western Targets.
Assay Results Pending
Analytical results for holes CO-01 and CO-02, drilled at the Eastern Target and disclosed in the Company's October 21s, 2025, news release, are expected within the next two weeks. Results for holes CO-03 through CO-05 will be announced once received, validated, and reviewed by GoldHaven's technical team.
GoldHaven will continue advancing the program over the coming weeks, integrating geological, structural, and geochemical data to refine targeting along both the East and West anomalies. Assay results from the initial drill holes are expected in the near term.

Rob Birmingham, CEO of GoldHaven Resources, commented:
"The completion of Hole CO-05 marks an important milestone as we advance systematic testing of the Copeçal targets. The identification of a thicker-than-anticipated saprolite profile and the transition into sheared basement rocks provide key geological information for refining our exploration model. We look forward to the pending assay results from the first two holes and to continuing our methodical approach to evaluating these priority 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.
