Southern Cross Gold Links Christina to Golden Dyke with 481m Mineralization

Milestone Hole SDDSC235 Unites Key Prospects

Southern Cross Gold Consolidated Ltd (ASX:SX2) has delivered a standout drilling result from its Sunday Creek Gold-Antimony Project in Victoria, with hole SDDSC235 intersecting a remarkable 481 metres of mineralization. This intercept effectively links the Christina prospect with the Golden Dyke corridor and extends into the Rising Sun corridor at a depth of 1,010 metres, marking a significant step-out nearly 300 metres west of previous drilling.

The hole returned a continuous gold grade of approximately 0.9 g/t uncut, punctuated by multiple high-grade assays including a blistering 0.8 metres at 141.0 g/t gold and individual samples reaching as high as 496 g/t gold. These results demonstrate that Christina hosts a mineralized system on par with the established Golden Dyke and Rising Sun zones, expanding the known footprint of this epizonal gold-antimony system.

Shallow Vein Sets and Antimony Confirmed in Western Extension

Alongside SDDSC235, two other definition holes from a new western drill pad, SDDSC220 and SDDSC232, also intersected gold mineralization within 15 to 60 metres of surface, confirming the presence of previously unidentified shallow vein sets. SDDSC220 notably returned 2.6 metres at 7.5 g/t gold equivalent from just 40 metres depth, while antimony assays reached up to 39.5% Sb over 0.1 metres in SDDSC235 and 12.4% Sb in SDDSC220, reinforcing the epizonal zonation typical of the Sunday Creek system.

These shallow antimony-rich zones are strategically important given antimony’s critical mineral status, with supply constraints globally and significant demand in defence and semiconductor sectors. Southern Cross’s Sunday Creek project is well positioned as a potential Western supplier, further underscored by its inclusion in the US Defense Industrial Base Consortium and alignment with AUKUS-related initiatives.

Expanding High-Grade Inventory and Ongoing Drill Campaign

The five holes reported add five new composite intersections exceeding 100 g/t gold, lifting Sunday Creek’s total to 93 such intersections, a notable increase from 88 previously. All new high-grade intercepts at Christina lie outside the company’s March 2025 exploration target, suggesting the system’s potential is broader than earlier anticipated.

With eleven rigs currently operating and 68 holes pending assay results, Southern Cross is executing a large-scale 200,000-metre drill program running through to the first quarter of 2027. This aggressive pace aims to further delineate the extensive ‘Golden Ladder’ vein structure that underpins the project’s scale, which already boasts drill-defined mineralization over a 1,550-metre strike length and from surface to depths exceeding 1,200 metres.

Technical and Strategic Significance

Preliminary metallurgical testing confirms the non-refractory nature of mineralization, with gold recoveries between 93% and 98% via gravity and flotation methods. The project’s dual gold-antimony profile enhances its strategic value, particularly amid global supply uncertainties for antimony, where China currently dominates production.

Southern Cross’s understanding of the geological architecture, informed by deep control holes like SDDSC207 and SDDSC213, has been critical in targeting mineralized corridors effectively. The company’s President & CEO Michael Hudson described SDDSC235 as one of the most important holes drilled to date, highlighting the continuity and high-grade nature of mineralization in previously untested ground.
