GOLDHAVEN HIGHLIGHTS COPECAL GOLD PROJECT'S POTENTIAL IN BRAZIL, ADVANCING ON ANGLOGOLD'S HISTORIC EXPLORATION WORK

Goldhaven Resources Corp. has provided an update on the Copecal gold project, an exciting early-stage gold exploration property in northern Mato Grosso, Brazil. With a rich history of exploration work conducted by AngloGold Ashanti from 2010 to 2016, the Copecal project holds strong potential for gold mineralization. The project is located within the Juruena gold province, a highly prospective region that has historically produced significant gold discoveries.

The Copecal gold project presents an exciting opportunity to build upon an extensive data set from one of the world's leading gold producers. AngloGold's extensive exploration efforts over six years laid a solid foundation for understanding the geological framework and mineralization potential of the property.

Key exploration activities conducted by AngloGold at the Copecal gold project include:

• Stream sediment and soil geochemistry: Over 3,861 geochemical samples were collected, identifying two prominent gold anomalies -- the northeast and southwest anomalies. The southwest anomaly displayed a strong geochemical footprint with gold values ranging up to 539 parts per billion.
• Auger and air-core drilling: A total of 49 auger drill holes (353.8 metres) and six air-core drill holes (85 metres) were completed to test soil anomalies. These programs successfully confirmed the presence of gold-bearing structures in depth, indicating strong continuity.
• Induced polarization (IP) geophysics: AngloGold conducted an IP survey to identify sulphide-associated mineralization. Results indicated moderate conductors, with the northeast anomaly showing the strongest chargeability response, suggesting the presence of sulphide-rich deformation zones.
• Rock and trench sampling: Despite a limited number of rock grab samples exceeding 10 parts per billion gold, trenching and soil grid sampling suggested an extensive gold-mineralized system worthy of further exploration.

The Copecal gold project -- a strong foundation from AngloGold's historic exploration work

Between 2010 and 2016, AngloGold Ashanti conducted extensive exploration work across the Copecal gold project and its surrounding tenements, investing approximately $1-million (U.S.) in geochemical surveys, geophysics and drilling. This work led to the identification of multiple gold-bearing anomalies, setting the stage for further exploration.

1. Stream sediment and soil geochemistry -- identifying large-scale anomalies

AngloGold executed a comprehensive geochemical program that included:

Stream sediment sampling: Targeted regional-scale anomalies, identifying areas with elevated gold concentrations.

• Soil sampling (400-metre-by-40-metre and 200-metre-by-40-metre grids): defined two primary anomalies -- the northeast and southwest anomalies -- with gold values reaching up to 539 parts per billion gold;
• Rock-chip sampling: confirmed the presence of gold-bearing quartz veins and structurally controlled mineralization.

The southwest anomaly, the most prominent identified to date, extends over a large area and aligns with regional shear zones that are known to host gold mineralization elsewhere in the Juruena gold province.

2. Drilling confirmed gold-bearing structures at depth

AngloGold followed up on its geochemical anomalies with air-core and auger drilling, successfully confirming gold mineralization at shallow depths:

• 49 auger drill holes (353.8 metres total) identified gold mineralization trends beneath the soil anomalies;
• Six air-core drill holes (85 metres total) further tested near-surface mineralization, confirming the presence of gold-bearing structures but remaining shallow in depth.

While these initial drill programs were not designed for resource definition, they provided critical evidence of bedrock-hosted gold mineralization, warranting further deeper exploration.

3. Induced polarization (IP) geophysics -- unveiling subsurface structures

Recognizing the structurally controlled nature of the Copecal mineralization, AngloGold executed IP surveys across the project. These surveys detected strong chargeability anomalies, particularly in the northeast anomaly, where geophysical responses suggested the presence of sulphide-rich, potentially gold-bearing structures at depth.

4. Structural interpretation and geological mapping -- key controls on gold mineralization

AngloGold's exploration confirmed that the Copecal project lies at the intersection of two major shear zones, characteristic of other significant gold deposits in the region. Gold mineralization appears to be associated with:

• Deep-seated west-northwest/east-southeast shear zones, key structures controlling mineralization in the Juruena province;
• East-west-trending second-order faults, likely playing a role in fluid flow and mineral deposition;
• Mafic and felsic intrusive rocks, similar to those hosting major gold deposits in the province.

These findings suggest that the Copecal gold project shares key geological characteristics with major gold deposits in the Juruena and Alta Floresta gold provinces.

A high-potential gold asset in a world-class region

The Juruena gold province has long been recognized as one of Brazil's most prospective regions for gold exploration, with historic production and numerous deposits discovered. The Copecal project is ideally positioned to benefit from this proven geological setting, with infrastructure advantages, including:

• Proximity to Alta Floresta (60 kilometres), a mining-friendly town with road access and services;
• Access to power, water and work force, critical for cost-effective exploration and development;
• Targeted land package (3,681 hectares), with ample room for expansion and new discoveries.

Goldhaven Resources now owns 100 per cent of the Copecal gold project in Brazil

With a solid foundation of historic exploration data, a favourable geological setting and a systematic exploration strategy, the Copecal gold project is ready to be advanced. As Goldhaven Resources develops this highly prospective asset, shareholders can expect a steady flow of updates and potential catalysts over Q2 and Q3 of 2025.

"The Copecal gold project represents an exceptional opportunity to build on a robust, high-quality data set from a leading gold producer," said Bonn Smith, chief executive officer of Goldhaven. "AngloGold's prior exploration has uncovered highly promising anomalies, providing us with a solid foundation to identify a major gold system. We view this as a highly compelling exploration venture within one of Brazil's most prolific gold belts. The depth of AngloGold's historical work has given us valuable insights into the underlying mineralization controls, positioning us to drive this project forward with precision and efficiency. Our goal is to continue advancing the Copecal gold project methodically, unlocking its full potential this year and into the future."
