Southern Cross Gold's Sunday Creek Project Continues to Validate Its Position as One of the Most Significant Global Gold-Antimony Discoveries in Recent Years

SXG’s latest drilling has revealed exceptional gold grades at depth at the historic Golden Dyke mine area, supporting the growth potential of this zone, with key highlights including:

• Hole SDDSC141 intercepted 5.5 metres at 25.4 g/t gold, including a very high-grade zone of 1.4 metre at 101.1 g/t gold, extending known mineralisation 100 metres to 200 metres deeper than previous drilling.
• The breakthrough came from a drill hole SDDSC0141 that extended nearly 550 metres below the surface, discovering multiple zones of high-grade gold and antimony mineralisation. This discovery is particularly significant as it extends the known mineralised area by up to 200 metres below previous drilling, demonstrating that the high-grade gold vein sets continue to depth.
• Mineralisation follows a distinct "ladder" structure, where the main host extends between the side rails deep into the earth, with multiple cross-cutting vein sets that host the gold forming the rungs. At least 66 such "rungs" have been identified to date.

The critical metal component adds another compelling dimension to this story. Sunday Creek's antimony content (approximately 20% of in-situ recoverable value) positions it as one of the few high-quality antimony projects in the Western world at a time when China's recent export restrictions are pressuring Western defence supply chains.

SXG’s systematic exploration approach is paying off, with five drill rigs currently operating at the site and a sixth scheduled to arrive in December 2024. This bold exploration program, which plans to complete 60 km of drilling over the next year, reflects SXG’s confidence in Sunday Creek's potential.

Current global uncertainty adds a compelling overlay to Sunday Creek as it is driving interest in both gold and critical minerals such as antimony. At the same time Sunday Creek offers exposure to these metals through a single, high-grade asset in a tier-one jurisdiction. We expect the next 12 months of drilling to prove transformative in revealing the deposit's true scale.
