Southern Cross Gold (ASX:SX2) reports exceptional drill results from its Golden Dyke prospect, with grades up to 254 g/t gold and significant antimony content, pushing deposit boundaries and confirming geological continuity at Sunday Creek.
- Golden Dyke intercepts include 1.6 m @ 55.3 g/t gold and 1.9% antimony
- Western boundary extended up to 50 m beyond current exploration target
- Antimony-rich zones with assays exceeding 10%, adding strategic value
- Infill drilling confirms predictable grade continuity supporting development
- Eleven rigs now active in a 200,000 m drill campaign through Q1 2027
Golden Dyke Delivers Exceptional High-Grade Intercepts
Southern Cross Gold Consolidated Ltd (ASX:SX2) has unveiled a fresh tranche of high-grade drill results from six holes at its Golden Dyke prospect within the Sunday Creek Gold-Antimony Project in Victoria. The standout intercept was 1.6 metres grading 55.3 grams per tonne (g/t) gold and 1.9% antimony from 313.8 metres downhole, underscoring the deposit’s rare dual-metal character. Several individual assays topped 100 g/t gold, with one hitting 254 g/t, while antimony assays reached as high as 10.6%. This combination is increasingly valuable given antimony's critical role in defence and semiconductor industries.
President and CEO Michael Hudson highlighted the geological consistency revealed by infill drilling. Holes SDDSC203 and SDDSC210, designed to test grade continuity, delivered multiple high-grade zones exactly as predicted by the company’s model. This predictability is crucial for advancing from exploration to development phases.
Deposit Growth in Multiple Directions
The drilling campaign also pushed Golden Dyke’s boundaries. Hole SDDSC197 extended the western edge by up to 50 metres beyond the current exploration target outline, while SDDSC193 confirmed mineralization continuing eastward and to greater depths. The deposit remains open in multiple directions, supporting the company’s view of a growing system. Southern Cross has now ramped up activity to eleven rigs on site, part of a 200,000-metre drill program scheduled to continue through to the first quarter of 2027.
These results build on the company’s recent progress, including a substantial cash position and a maiden resource target planned for early 2027. The ongoing drill program and expanding footprint are critical steps toward demonstrating the project’s scale and economic potential, complementing previous findings of deep mineralization at Sunday Creek.
Strategic Value of Antimony Credits
Sunday Creek’s dual gold-antimony profile sets it apart in the critical minerals landscape. Antimony, a metal dominated by Chinese supply, is vital for flame retardants, munitions, batteries, and semiconductors. Southern Cross’s assays reveal antimony grades exceeding 10% in several intervals, with one hole (SDDSC210) returning 227 g/t gold alongside 10.6% antimony. This positions Sunday Creek as a potentially important Western-aligned antimony source amid global supply concerns.
The company uses a gold equivalent formula incorporating antimony at a 2.39 ratio, based on comparable metrics from the nearby Costerfield mine operated by Mandalay Resources Ltd. This methodology reflects recoverable value and underpins Southern Cross’s exploration targeting and valuation approach.
Robust Exploration Program and Technical Foundations
The six reported holes were drilled in alternating directions to optimise intersection angles across steeply dipping vein sets. The geological model describes a “Golden Ladder” structure with multiple cross-cutting vein sets extending over 1,550 metres strike and more than 1,100 metres depth. The project now boasts 85 composite intersections exceeding 100 g/t gold and 104 exceeding 10% antimony from nearly 120,000 metres drilled since 2020.
Preliminary metallurgical work indicates non-refractory mineralization amenable to conventional processing with gold recoveries between 93% and 98%. Southern Cross’s strong cash reserves and strategic freehold land ownership underpin its capacity to advance the project milestone by milestone.
These latest results follow the company’s recent $123M cash and maiden resource target announcement, reinforcing a trajectory from exploration success to tangible development potential.
Bottom Line?
Southern Cross Gold’s expanding high-grade gold-antimony zones and predictable geology at Sunday Creek provide a solid platform for upcoming resource estimates and development studies.
Questions in the middle?
- How will pending assay results from 46 holes influence the scale and grade continuity of Sunday Creek?
- What impact will metallurgical and mining studies have on the economic viability of the gold-antimony mineralization?
- How might global antimony supply dynamics affect Southern Cross Gold’s strategic positioning and project valuation?
