GoldHaven Resources Corp. ("GoldHaven" or the "Company") is pleased to report that an independent specialist geology consultant has validated and enhanced the geological understanding of the Company's 100%-owned Copeçal Project ("Copeçal" or the "Project") in Mato Grosso State, Brazil, following a detailed review of drill core and data from the Company's inaugural diamond drilling program of 9 holes totaling 1,085.7m.
HIGHLIGHTS
- Independent review confirms potential for large-scale, structurally controlled hydrothermal gold system
- Clear vectors to higher-grade mineralization at both East and West Targets
- ~6 km gold-in-soil anomaly defining a district-scale system with large, underexplored zones, originally identified by AngloGold Ashanti
- West Target: Gold linked to fold hinge zones and increasing sheeted vein density providing a vector towards potentially stronger mineralization.
- East Target: Copper-gold system with zoned sulphide assemblages (chalcopyrite–bornite) providing a higher temperature vector.
- Alta Floresta Gold Belt: Situated within a prolific and emerging gold district
- Multiple high-priority targets: System remains open with significant follow-up drilling potential
The independent review confirms and reinforces Copeçal's potential as a large-scale mineralized system with clear vectors toward higher-grade zones, while highlighting multiple untested high-priority targets. This meaningfully enhances the project's exploration potential ahead of drilling and underpins GoldHaven's strategy to advance an expanded drill program in 2026.
Gustavo Almeida, Senior Project Geologist, Brazil, commented:
"The geological features identified at Copeçal with the initial phase of drilling remain encouraging and consistent with the expected signature of an intrusion-related, hydrothermal system. The presence of strong structural kinematic indicators, sheeted veining with quartz rimmed with biotite indicating potassic alteration at the West Target and the appearance of zoned chalcopyrite-pyrite and chalcopyrite-bornite sulphide assemblages associated with surface gold enrichment in soil and saprolite at the East Target, suggests we are vectoring towards stronger mineralization. At the scale of the project, the association of gold and gold-copper anomalism with fold hinge structures and magnetic features provides a clear and technically sound framework for follow-up drilling."
INDEPENDENT GEOLOGICAL REVIEW – KEY FINDINGS
The independent consultant conducted a detailed review of geological data and drill core, confirming that mineralization at Copeçal is controlled by structural architecture and hydrothermal alteration systems.
West Target – Structural Control & Gold Enrichment
At the West Target, the consultant identified:
- Higher-grade gold enrichment associated with asymmetric to isoclinal fold structures
- Dense sheeted quartz veinlet systems hosted within phyllic altered meta-granodiorite
- Potassic alteration, evidenced by crystalline biotite along vein margins within wide intervals
indicating potential for a robust hydrothermal system along strike to the west and at depth.
Importantly:
- The core of the West Target gold-in-soil anomaly remains largely untested and represents a high-priority drill target
- This anomaly aligns with a fold hinge and closure zone interpreted from drone magnetic data.

East Target – Mineral Zonation & Vectoring
At the East Target, the consultant confirmed:
- A northerly dipping, shear-hosted mineralized zone
- Distinct zoned sulphide assemblages:
- Chalcopyrite–pyrite
- Chalcopyrite–bornite, suggesting increasing temperature and providing a temperature vector.
- Elevated magnetic susceptibility in the core of the system
These features represent a clear vector towards potential stronger mineralization, both at depth and along strike.

STRONG HISTORICAL FOUNDATION
The Copeçal Project benefits from historical exploration conducted by AngloGold Ashanti, which invested approximately US$1 million in exploration.
Key highlights include:
- A ~6-kilometre gold-in-soil anomaly, demonstrating district-scale potential
- Identification of multiple target zones across the Project
- Location within the Juruena Magmatic Arc / Alta Floresta Gold Belt, a known gold-producing terrane
GoldHaven's modern work has validated and refined these targets, advancing the Project to its drill program.
MODERN EXPLORATION PROGRAMS
- 107 auger drill holes (2,153 metres) defining gold anomalies
- VLF-EM survey completed by Avant Geofísica
- Drone magnetic surveys identifying fold structures and intrusive controls
- Integrated targeting using geochemistry, geophysics, and structural interpretation
INTERPRETATION & NEXT STEPS
The independent review confirms Copeçal as a potentially large-scale hydrothermal system with strong structural controls and intrusion-related, porphyry-style alteration signatures. These combined structural, alteration, and sulphide characteristics are consistent with systems that host higher-grade mineralization at depth, significantly increasing the probability of success in follow-up drilling.
GoldHaven is advancing:
- Detailed structural modelling and 3D interpretation
- Target refinement across both East and West zones
- Phase II drill program (Q2) to test high-priority structural and geophysical targets
CEO COMMENTARY
"This independent review adds important technical validation and strengthens our confidence that Copeçal hosts a large-scale mineralized system," stated Rob Birmingham, CEO of GoldHaven. "Importantly, we are now seeing clear vectors toward stronger mineralization at both the East and West targets, with significant portions of the system still untested. As we move into our next phase of drilling, we believe Copeçal has the potential to deliver meaningful exploration results."

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.
