Southern Cross Gold Unveils Massive High-Grade Gold-Antimony Zone at Golden Dyke
Southern Cross Gold reports a major breakthrough at its Golden Dyke prospect with a 168-meter high-grade gold-antimony mineralized intersection, hinting at a vast, connected system with Rising Sun. The discovery underscores the strategic value of the Sunday Creek project amid critical mineral supply concerns.
- 168m continuous mineralization averaging 3.0 g/t gold equivalent at Golden Dyke
- Ultra-high-grade gold hits including 254 g/t over 0.4m and 244 g/t over 0.1m
- Discovery of new high-grade vein with 52.3% antimony, third-highest at project
- Evidence suggests Golden Dyke and Rising Sun deposits may be one continuous system
- Plans underway for extensive 200,000m drilling program through 2027
A Landmark Intersection at Golden Dyke
Southern Cross Gold Consolidated Ltd (ASX, SX2) has announced a significant milestone in its exploration campaign at the Sunday Creek Gold-Antimony Project in Victoria, Australia. Drillhole SDDSC177 intersected an extraordinary 168 meters of continuous mineralization averaging 3.0 grams per tonne (g/t) gold equivalent, including multiple ultra-high-grade gold zones. Among these were spectacular hits such as 254 g/t gold over 0.4 meters and 244 g/t over 0.1 meters, underscoring the project's potential to deliver both scale and exceptional grade.
Expanding the System and Vertical Continuity
This intersection not only confirms a substantial vertical extension of mineralization by 100 meters but also reveals a newly discovered high-grade vein set boasting 52.3% antimony; the third-highest antimony grade recorded at Sunday Creek. This dual commodity potential is particularly noteworthy given antimony's critical role in defense and semiconductor industries, sectors currently facing supply constraints due to geopolitical factors.
Geological Link to Rising Sun Deposit
Geological and assay data suggest that Golden Dyke and the nearby Rising Sun deposit may be part of a single, continuous mineralized corridor. This connection could effectively double the scale of the system, enhancing the project's strategic importance. Both deposits exhibit similar characteristics, including visible gold, high antimony grades approaching pure stibnite, and discrete high-grade cores within broader mineralized envelopes.
Strategic Importance Amid Critical Mineral Supply
Southern Cross Gold’s Sunday Creek project stands out not only for its gold potential but also for its significant antimony content. Antimony is classified as a critical mineral by multiple governments due to its essential applications in flame retardants, munitions, and energy transition technologies. With China limiting antimony exports from September 2024, Western markets face supply risks, positioning Sunday Creek as a potentially vital source of this strategic metal.
Looking Ahead, Aggressive Drilling and Exploration
The company has mobilized nine rigs and plans to drill approximately 200,000 meters through to 2027. A key focus is testing an 80 to 100-meter strike gap between Golden Dyke and Rising Sun, an area currently underexplored but with high potential to host additional mineralization. This aggressive program aims to delineate the full extent of the mineralized system and further validate the project's district-scale potential.
Bottom Line?
Southern Cross Gold’s Golden Dyke results mark a pivotal step in unlocking a major gold-antimony system with strategic implications for critical mineral supply.
Questions in the middle?
- How will upcoming assay results from the 37 pending drill holes impact the resource model?
- What metallurgical challenges remain in processing the high-antimony ore economically?
- Can the Golden Dyke and Rising Sun deposits be definitively linked to form a single resource?
