Southern Cross Gold Confirms Antimony-Rich High Grades at Sunday Creek

Antimony Emerges as Key Player in Golden Dyke

Southern Cross Gold Consolidated Ltd (ASX:SX2) has delivered a compelling update from its Sunday Creek Gold-Antimony Project in Victoria, confirming that antimony is not just a byproduct but a dominant feature in the upper Golden Dyke zone. The highlight; a 7.9-metre intercept grading 19.9 g/t gold equivalent (AuEq), including 7.1% antimony (Sb) and 2.8 g/t gold; underscores the project's dual-metal character, with antimony concentrations reaching up to 47% in individual assays.

These results are significant because they validate the expected geological zonation typical of epizonal gold-antimony systems, where antimony concentrates near surface, transitioning to gold dominance at depth. The upper Golden Dyke, the most intensively drilled area, sits just below the base of the planned exploration decline, positioning these high-antimony zones as accessible and strategically valuable.

Expanding Vein Networks and Predictable Grade Continuity

The drilling campaign, reporting on six infill holes, identified four new vein sets and extended known veins by up to 170 metres, including a substantial up-dip extension of the GD35 vein. This structural expansion, coupled with consistent high-grade intercepts exactly where predicted, boosts confidence in the geological model and supports the feasibility of future mining studies.

Notably, assays from hole SDDSC233 included three gold assays exceeding 50 g/t and seven antimony assays above 20%, reinforcing the continuity and robustness of mineralization. The presence of multiple vein sets with both gold and antimony grades highlights the complexity and richness of the system.

Strategic Critical Mineral with Global Supply Constraints

Antimony, a critical mineral for defence and semiconductor industries, is in short supply globally, with China dominating production and refining. Southern Cross Gold’s Sunday Creek project, with over 108 composite intersections exceeding 10% Sb, offers a rare Western source of this strategic metal. The company emphasises antimony’s relevance for munitions primers and flame retardants, aligning with heightened geopolitical interest in secure critical mineral supply chains.

CEO Michael Hudson stressed the strategic importance: "Sunday Creek is shaping up as a project where the antimony alone would attract serious attention, quite apart from the gold which forms 80% of the in situ recoverable value." The project’s location in a tier-one jurisdiction and substantial freehold land ownership further enhance its appeal.

Robust Metallurgical Profile and Ongoing Drill Momentum

Preliminary metallurgical testing indicates non-refractory mineralization amenable to conventional processing, with gold recoveries between 93% and 98% through gravity and flotation. This bodes well for economic extraction of both gold and antimony products.

Southern Cross Gold is pressing ahead with an ambitious 200,000-metre drill program through Q1 2027, currently operating 11 rigs with 69 holes pending assay results. The company’s methodical approach to infill and step-out drilling is steadily building a detailed picture of the deposit’s extent and grade distribution, reinforcing its resource potential.

While the latest results confirm high-grade growth and antimony dominance in the upper Golden Dyke, the full scale and economic impact will unfold as pending assays and subsequent studies refine the resource model and mining scenarios.
