Southern Cross Gold Extends High-Grade Gold-Antimony at Sunday Creek

Record-Setting Drill Results Highlight Sunday Creek’s Potential

Southern Cross Gold (ASX:SX2) has delivered another tranche of impressive drill results from its Sunday Creek Gold-Antimony Project in Victoria, reinforcing the project's status as a high-grade, critical metals discovery. The standout intercept came from hole SDDSC202 at the Apollo East prospect, delivering 36.6 metres at 6.5 g/t gold equivalent (AuEq), including an eye-watering individual assay of 493 g/t gold and 29.1% antimony. This intercept not only confirms the presence of robust mineralization but also reveals two previously unrecognised high-grade vein sets, enriching the geological model of the Apollo East vein architecture.

Adding to the excitement, drill hole SDDSC214W1 extended mineralization 20 metres further east than previously mapped, with assays including 0.5 metres at 251.4 g/t AuEq (232 g/t gold and 8.1% antimony). This expansion opens new ground at Apollo East, suggesting the system’s strike length is still growing. Meanwhile, SDDSC217 returned the shallowest high-antimony results to date, confirming strong critical metal tenor near surface with assays up to 31.3% antimony and 55.8 g/t gold.

Aggressive Drilling Campaign Underway

The company currently operates eleven drill rigs on site, actively processing results from 67 pending holes as part of a 200,000-metre drill program scheduled through to the first quarter of 2027. Southern Cross Gold’s President and CEO Michael Hudson emphasised the momentum, stating the program is accelerating the definition of the full extent of this exceptional gold-antimony system. The ongoing drilling is systematically targeting the “Golden Ladder” structure, a network of steeply dipping vein sets extending over 1,550 metres of strike and to depths exceeding 1,200 metres.

This relentless pace of exploration builds on previous successes, including deep mineralization confirmed at Golden Dyke and Apollo, and a growing inventory of high-grade intersections. The company’s strategic focus on both gold and antimony, a critical metal with growing geopolitical importance, positions Sunday Creek as a key asset in the Western supply chain for critical minerals.

Critical Metal Antimony Adds Strategic Value

Antimony, which accounts for approximately 21% to 24% of the in situ recoverable value at Sunday Creek on a gold equivalent basis, is a metal of increasing importance for defence, semiconductors, and energy transition technologies. With China controlling over half of global antimony supply and imposing export restrictions, Southern Cross Gold’s project in a tier-one jurisdiction gains strategic significance. The company’s inclusion in the US Defense Industrial Base Consortium and alignment with Australia’s AUKUS legislative framework further underline its potential role as a Western antimony supplier.

Preliminary metallurgical testing indicates non-refractory mineralization amenable to conventional processing, with gold recoveries ranging from 93% to 98% through gravity and flotation methods. The production of a high-quality antimony concentrate (~50% Sb, <0.2% As) with recoveries between 83% and 93% strengthens the economic case for the project.

Project Scale and Next Steps

Southern Cross Gold’s Sunday Creek project spans 16,900 hectares with 1,392 hectares of strategic freehold land, hosting a prolific vein system with 96 composite intersections exceeding 100 g/t gold from nearly 124,000 metres of drilling reported since 2020. The ongoing drill program aims to further delineate the resource, with a maiden inferred resource targeted in early 2027.

Investors should watch for upcoming assay results from the 67 holes currently being processed, as well as updates on resource modelling and metallurgical studies. The company’s methodical approach, backed by robust cash reserves and a clear strategic vision, continues to advance Sunday Creek from a drill discovery toward potential development.
