GOLDHAVEN RESOURCES INITIATES VLF ELECTROMAGNETIC SURVEY OVER PRIORITY TARGETS AT COPEÇAL GOLD PROJECT IN BRAZIL

Goldhaven Resources Corp. has initiated the VLF electromagnetic (VLF-EM) survey at the Copecal gold project, which is being completed by Avant Geofisica out of Belo Horizonte, Brazil. The survey will target structural-alteration trends believed to be favourable for gold mineralization, covering both the east and west gold-in-soil anomalies as well as their potential strike extensions. Integrating VLF-EM geophysics with the recently completed auger litho-geochemistry program will provide Goldhaven with a robust targeting framework for finalizing priority phase 1 diamond drill target collar locations over the east and west anomalies. The survey is expected to take two weeks to complete.

Avant Geofisica has been supporting mining companies in Brazil since 2004, specializing in drone magnetometry, lidar topography and multispectral analysis. Their team is highly qualified and uses state-of-the-art equipment/sensors. Avant Geofisica is a pioneer in drone magnetometric surveying in Brazil, and the brand has established itself as a benchmark in the industry.

Rob Birmingham, chief executive officer of Goldhaven Resources, commented: "We are thrilled to initiate the VLF-EM survey at the Copecal project, a key step in our strategy to unlock the project's full potential. By working with Avant Geofisica -- whose deep familiarity with the area ensures high-quality data -- we aim to generate meaningful geophysical insights that will directly support and refine our upcoming diamond drill program in Q3, ultimately enhancing shareholder value."

Auger drill program samples received

The 1,325 samples, including QA/QC (quality assurance/quality control) samples, collected from the 2,153-metre auger drill program at the Copecal gold project have been received by ALS Global Laboratories. Assay results are expected to be reported in late July or early August.

The Auger drill program included 92 auger holes which systematically covered the main area of the east anomaly on a 100-metre-by-50-metre grid while a further 15 reconnaissance holes targeting geochemical -- structural targets projected toward the southeast from the western anomaly. Holes were drilled from surface to the weathered rock (regolith) -- fresh rock interface or to a maximum depth of 30 m. The average hole depth was 20.13 metres with the hole depth range of two m to 30 m.

About the Copecal gold project: a brief history

The Copecal 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 (for example, Serabi, Jaca) and epithermal-style deposits (for example, 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 Copecal 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 Copecal 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.

About Goldhaven Resources Corp.

Goldhaven Resources is a Canadian junior exploration company focused on acquiring and exploring highly prospective land packages in North and South America. The company's projects include (i) the flagship Magno project, a district-scale polymetallic property adjacent to the historic Cassiar mining district in British Columbia; (ii) the Three Guardsman project, which exhibits significant potential for copper and gold-skarn mineralization; (iii) the Copecal gold project, a drill-ready gold project located in Mato Grosso, Brazil, with a six-kilometre strike of anomalous gold-in-soil samples; and (iv) three critical mineral projects with extensive tenement packages totalling 123,900 hectares: Bahia South, Bahia North and Iguatu projects located in Brazil.
