Golden Cross Resources Unveils High-Potential Copper Zones at Copper Hill

Golden Cross Resources Uncovers Promising Geochemical Results at Copper Hill

Golden Cross Resources Ltd (GCR) has announced encouraging results from its comprehensive surface soil sampling program at the Copper Hill exploration, revealing several promising geochemical anomalies that enhance the exploration potential of this copper-gold asset.

Strategic Sampling Program Builds on Historical Data

The company recently completed analysis of 262 soil samples collected during March-April 2025, strategically targeting seven sub-areas within the Copper Hill license (EL6391). This systematic program follows a tenement-wide gravity survey completed in February 2025 and addresses gaps in historical geochemical coverage.

The sampling campaign was specifically designed to:

• Validate areas previously tested with older analytical techniques
• Expand elemental data beyond limited historical suites
• Close off open geochemical anomalies
• Standardize sampling methodologies across the project

Each sample was analyzed for gold using 50g fire assay and a comprehensive suite of 36 elements using ICP methodology at ALS Global laboratories.

Key Exploration Highlights Reveal Promising Targets

While soil geochemical values were generally low-tenor, several significant findings emerged from Golden Cross Resources' Copper Hill exploration program:

• Wattle Hill Southeast: Returned the highest copper value of 2,060 ppm along with moderately elevated gold, extending the Wattle Hill zone toward Vale Head
• Shades Road area: Produced the highest gold value of 0.43 g/t alongside elevated zinc values, potentially indicating deeper mineralization
• Larras Lee West: Identified a previously unrecognized zone (~1km × 1km) with moderately elevated copper, gold, and molybdenum requiring infill sampling
• Copper Hill Mineral Corridor: Confirmed as a 5km-long alignment of copper-gold occurrences with new sampling extending known anomalies

These results are particularly significant as they help define the broader mineralized footprint beyond the established Copper Hill resource.

Understanding Porphyry Systems: Why Soil Geochemistry Matters

Porphyry copper-gold deposits like Copper Hill typically form large, low-grade ore bodies centered around intrusive igneous rocks. Surface geochemistry provides critical insights into the extent and nature of these systems by mapping the dispersion patterns of metals and pathfinder elements.

In porphyry systems, specific elemental associations are particularly important:

• Copper and gold form the core economic elements
• Molybdenum often indicates proximity to the central intrusion
• Zinc and arsenic can define peripheral zones or structural controls
• Silver may indicate epithermal components or specific fluid pathways

The zonation patterns in copper-gold deposits identified in Golden Cross Resources' Copper Hill exploration survey—with copper-gold-molybdenum in central areas and zinc-arsenic in peripheral zones—align with classic porphyry models, validating the exploration approach and potentially indicating a well-developed mineralized system.

"The completion of this systematic geochemical program represents an important step in our exploration strategy for Copper Hill. By addressing gaps in historical data and identifying new anomalies, we've enhanced our understanding of the broader mineralized system and generated several promising targets for follow-up work," commented Jordan Li, Executive Chairman.

Strategic Position in Premier Gold-Copper District

The Copper Hill project occupies a prime position within the Molong Volcanic Belt of the Macquarie Arc, the same geological terrain that hosts world-class deposits including:

• Cadia-Ridgeway (Newmont)
• Boda and Kaiser prospects (Alkane Resources)

Located approximately 50km north of the Cadia operation, Copper Hill sits on the northern edge of the Lachlan Transverse Zone, a major structural corridor associated with significant mineralization throughout the region.

The project already hosts a substantial Mineral Resource Estimate (MRE) updated in September 2022, with combined Indicated and Inferred resources totaling 87 million tonnes at 0.32% copper and 0.27 g/t gold. Furthermore, companies like Alkane Resources with promising gold drill results have demonstrated the potential of this mineral-rich region.

Forward-Looking Exploration Strategy

Golden Cross Resources has outlined several next steps to advance the Copper Hill exploration project:

1. Integration of new data with historical results to update geochemical datasets
2. Identification of areas requiring infill sampling (particularly at Larras Lee)
3. Refinement of exploration targeting based on integrated geophysical and geochemical data
4. Potential gravity infill or IP surveying at Larras Lee area

Investment Significance

The Copper Hill project represents a compelling investment opportunity for several reasons:

1. Established Resource Base: The current MRE provides a solid foundation for potential development
2. Strategic Location: Within the highly prospective Macquarie Arc that hosts multiple world-class deposits
3. Exploration Upside: New geochemical anomalies indicate potential for resource expansion
4. Systematic Approach: Methodical exploration program building a comprehensive understanding of the deposit
5. Multiple Targets: Several distinct areas of interest provide multiple opportunities for discovery

The systematic approach to Golden Cross Resources' Copper Hill exploration program, combined with its strategic location in a premier copper-gold district, positions the company to potentially unlock significant additional value from this asset as exploration progresses. In addition, the investment significance of copper-gold projects continues to grow as the global demand for these metals increases. Similarly, companies like Great Boulder Resources have been announcing new gold targets in their exploration projects, highlighting the ongoing interest in precious metals discovery.
