Vancouver, British Columbia, August 7, 2025 – GoldHaven Resources Corp. ("GoldHaven" or the "Company") (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) is pleased to announce, further to its news release dated May 16, 2025, the refiling of an independent technical report for its Copeçal Project prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects. The technical report, titled “Technical Report on the Geology, Mineralization and Exploration of the Copeçal Gold Project, Mato Grosso State, Northwestern Brazil” and with an effective date of May 29, 2025 can be found on the Company’s SEDAR+ profile at www.sedarplus.ca and on the Company’s website here.
Key Highlights:
Strategically Located in Tier-One Mining Jurisdiction
The Copecal Gold Project spans 3,681.76 hectares across two contiguous exploration permits in northern Mato Grosso, Brazil. The property benefits from inclusion in the “Legal Amazonia” zone, offering tax incentives and access to robust infrastructure. The site is within 60 km of Alta Floresta, a regional hub with daily commercial flights and established mining services and is connected via well-maintained roadways and hydroelectric power. These attributes provide a solid foundation for cost-effective exploration and future development.

100% Ownership Through Recent Strategic Acquisition
In January 2025, GoldHaven acquired the Copecal Project via a three-cornered amalgamation with Boa Gold Corp., consolidating full ownership of the mineral rights through its Brazilian subsidiary, Ouro Resources Do Brasil Ltda. The acquisition included two key exploration permits originally explored by AngloGold Ashanti, securing GoldHaven's position in one of Brazil’s most prospective gold belts.
Geological Setting Favourable for Orogenic Gold Systems
The Copecal Project is situated within the Juruena Magmatic Arc, a Paleoproterozoic geological structure that has historically yielded significant gold discoveries. The property is hosted in a 20 km-wide sinistral shear corridor—a structural setting strongly associated with orogenic gold deposits. Ground magnetometry and soil geochemistry confirm the presence of multiple shear-related gold-bearing structures, indicating strong potential for mesozonal, shear zone-hosted mineralization.

Historic Exploration by AngloGold Ashanti Defines Key Targets
Between 2010 and 2016, AngloGold Ashanti conducted extensive early-stage exploration, including soil and stream sediment geochemistry, auger and air core drilling, and ground geophysical surveys. This work identified two major soil anomalies and a cluster of 13 auger drill holes with consistent gold values exceeding 15 ppb Au—interpreted as indicators of primary mineralization. Despite encouraging results, follow-up was limited, leaving significant upside potential for further discovery.

Path Forward: Defined Targets and Efficient Exploration Strategy
GoldHaven is in the process of refining exploration targets through additional drone magnetometry and auger drilling. The SW-I, SW-II, and SW-III auger clusters represent priority drill targets, with structural and geochemical alignment supporting potential for gold mineralization. A two-phase exploration program was recommended, beginning with soil and auger infill sampling and shallow drilling. Following the completion of the drone geophysical survey and auger sample assay interpretation the Company will prepare for its maiden drill program.
