Copper Hill Soil Sampling Reveals 2060 ppm Copper and 0.43 ppm Gold Peaks

Context and Methodology

Golden Cross Resources Ltd (ASX – GCR) has announced the completion of a detailed surface geochemistry sampling program at its Copper Hill project in New South Wales. Conducted over March and April 2025, the program involved collecting 262 soil samples across the EL6391 tenement, following a comprehensive gravity survey earlier in February. This methodical approach aims to build on previous sampling campaigns from 2021 to 2023, which targeted selective areas with older techniques and limited elemental suites.

The latest sampling employed advanced laboratory analysis by ALS Global, using a 50-gram fire assay for gold and inductively coupled plasma (ICP) methods for a broad suite of 36 elements, including copper, silver, molybdenum, and key pathfinder elements. This comprehensive elemental profiling is designed to better delineate geochemical anomalies and support exploration targeting.

Key Findings and Geological Insights

The results generally show low tenor geochemical values across the sampled areas, consistent with closing off previously open zones or indicating potential deeper mineralisation. Notably, isolated highs of 2060 ppm copper at Wattle Hill and 0.43 ppm gold at Shades Road stand out as significant anomalies. Copper remains strongly elevated along the Copper Hill Mineral Trend, with additional moderate elevations in gold, molybdenum, arsenic, and zinc in various sub-areas.

Several zones warrant further attention, including the Dash North area where a strong arsenic trend correlates with high silver in rock chips and malachite occurrences, suggesting skarn mineralisation. The Wattle Hill Southeast extension also shows promising copper and gold values extending the mineral corridor. Conversely, some areas such as Roseleigh and Copper Hill East showed no significant geochemical zones, highlighting the variability within the tenement.

Strategic Importance and Next Steps

Copper Hill sits within the Macquarie Arc volcanic belt, a prolific gold-copper province hosting major deposits like Cadia-Ridgeway. Golden Cross’s 2022 Mineral Resource Estimate underscored the project’s potential, and these new geochemical results provide critical data to refine exploration models. The company plans to integrate the 2025 data with previous surveys to update geochemical maps, identify infill sampling needs, and sharpen drill targeting strategies.

Future work will likely include infill sampling at 100m spacing in key zones such as Dash North to verify anomaly continuity and potential subsurface mineralisation. Additional geophysical surveys, including gravity infill or induced polarization (IP), are also under consideration, particularly around the Larras Lee area where recent gravity data suggested further investigation.

Golden Cross Resources continues to apply rigorous JORC-compliant methodologies, ensuring data quality and transparency. The company’s methodical exploration approach reflects a commitment to unlocking Copper Hill’s value within a highly prospective geological setting.
