Mawson Gold Limited announced that Southern Cross Gold Ltd. had made another significant discovery at the 100%-owned Sunday Creek gold and antimony project, which is located an hour’s drive north of Melbourne. The critical metallic element adds another compelling dimension to this story. Sunday Creek’s antimony content (approximately 20% of in situ recoverable value) makes it one of the few high-quality antimony projects in the Western world, at a time when recent export restrictions imposed by China are weighing on Western defense supply chains.
SXG’s systematic approach to exploration is paying off, with five drilling rigs currently operating at the site and a sixth scheduled to arrive in December 2024. This bold exploration program, which plans to carry out 60 km of drilling over the next year, reflects SXG’s confidence in the potential of Sunday Creek. The current global uncertainty adds an irresistible dimension to Sunday Creek, as it sparks interest in both gold and key minerals such as antimony.
At the same time, Sunday Creek provides exposure to these metals through a single high-grade asset in a leading jurisdiction. The company expects the next 12 months of drilling to prove transformative in revealing the true scale of the deposit. Mineralization follows a distinct “ladder” structure, where the main host (100-200 m wide) extends between side rails and extends deep into the earth, with multiple sets of cross veins that contain gold and form the ranks.
Each of these “echelons” contains the potential for high-grade gold and antimony mineralization, of which at least 66 have been defined to date. The latest hole, SDDSC141, was strategically positioned to test the system at depth, drilling parallel to the main structure. It made it possible to intercept eight distinct mineralized zones, each representing one of the rungs of the scale. The hole was drilled between 65 and 100m below a previous successful hole (SDDSC132) and intersected several high-grade intervals, including an impressive 5.5m zone grading 26.1g/t gold equivalent from of 589.3 m depth, while testing a prospective corridor of 283 m (cumulative length of dyke and sediments altered by sericites and carbonates).
SDDSC141 includes 9 intersections of Au > 20 g/t (up to 196 g/t) and 5 intersections of Sb > 2% (up to 4.1%). This hole is the fourth in a program to test high-grade mineralization at depth beneath the prolific Golden Dyke mine. Pending Results and UpdateSXG has planned 60km of drilling at Sunday Creek over the next year.
Sixteen holes (SDDSC129, 133, 136, 139-140, 142-150, 146W1, 149W1, 120W1) are currently processed and analyzed, and five holes (SDDSC149W1, 151, 152, 153, 154) are in progress.
