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

Key Highlights:

• SDDSC177 drill hole returns 168m at 3.0 g/t AuEq including 6.2m @ 16.5 g/t AuEq
• Discovery of 52.3% antimony – third highest in project history
• Evidence mounts of Golden Dyke and Rising Sun forming a single connected system
  
   

Southern Cross Gold Consolidated Ltd (ASX: SX2 | TSX: SXGC | OTCQX: SXGCF) has struck another significant milestone at its 100%-owned Sunday Creek Gold-Antimony Project in Victoria, with new drill results from the Golden Dyke prospect revealing exceptional mineralization and further proof of the project’s expanding scale.

The standout result came from drillhole SDDSC177, which delivered 168 metres at 3.0 g/t gold equivalent (AuEq), including a 6.2m intercept grading 16.5 g/t AuEq, underscoring the system’s strong gold and antimony potential.

President and CEO Michael Hudson said the results “demonstrate the substantial metal endowment at Golden Dyke,” noting the discovery of a new high-grade vein set that returned 52.3% Sb over 0.2m with 35.9 g/t Au — the third-highest antimony assay ever recorded at Sunday Creek.

“The 168-metre intersection in SDDSC177 represents a significant system-scale result at Golden Dyke, comparable to the landmark intersection at Rising Sun,” Hudson explained. “We’ve confirmed a 100-metre vertical extension on the GD120 vein set and discovered a new high-grade core, showing the growing continuity and strength of the system.”

Connecting the Dots Between Golden Dyke and Rising Sun

The drilling results reinforce growing evidence that Golden Dyke and Rising Sun could be part of the same mineralized corridor. Southern Cross identified an 80–100 metre untested strike gap between the two zones — an area now prioritized for drilling.

Hudson added, “Golden Dyke is increasingly looking like part of the same connected system as Rising Sun. We’re seeing consistent visible gold, high antimony approaching pure stibnite, and discrete high-grade cores within broader halos.”

Highlights from the Drill Program

• Ten vein sets were intercepted in SDDSC177, showcasing the complexity of the mineralized system.
• Cumulative intercepts exceeded 500 gram-metres, with multiple assays surpassing 100 g/t Au.
• Bonanza-grade intercepts included 254 g/t Au over 0.4m, 244 g/t Au over 0.1m, and 184 g/t Au over 0.2m.
• A new high-grade antimony interval graded 52.3% Sb, among the top results across the project.
• A follow-up hole, SDDSC182, intersected 1.5m @ 39.1 g/t AuEq (19.5 g/t Au, 8.2% Sb) and 4.4m @ 7.8 g/t AuEq (5.1 g/t Au, 1.1% Sb), further confirming mineralization depth and consistency.
  
   

Southern Cross has now repositioned its deep core rig to test these newly identified corridors, while maintaining nine active rigs across the project as part of a 200,000-metre drill campaign extending through Q1 2027.

Strategic Relevance Amid Antimony Supply Constraints

Beyond its impressive gold grades, Sunday Creek’s dual gold-antimony composition gives it critical strategic value. Antimony — used in defense, semiconductors, and energy storage — has come under renewed global scrutiny after China imposed export restrictions in 2024, tightening supply of the metal that it dominates globally.

Sunday Creek’s geology, characterized as an epizonal gold-antimony system, positions Southern Cross as a key Western supplier in an increasingly geopolitically sensitive market. The company is also a member of the US Defense Industrial Base Consortium (DIBC), aligning with AUKUS defense priorities for critical minerals.

Antimony contributes about 20–24% of Sunday Creek’s in-situ recoverable value, according to company data, complementing strong gold recoveries of up to 98% in metallurgical testing.

Project Snapshot

Located 60 km north of Melbourne, the Sunday Creek project spans 16,900 hectares and hosts five mineralized zones: Golden Dyke, Rising Sun, Apollo, Christina, and Leviathan. Southern Cross holds both exploration rights and over 1,000 hectares of freehold land, strengthening its strategic control.

To date, the company has drilled more than 97,000 metres across 217 holes, reporting 71 intersections over 100 g/t AuEq x m, highlighting the district’s continuity and scale.

Market Snapshot

At the time of writing this article, SX2 shares were trading at A $8.44, up by 6.03%. 

SX2 market cap stands at A $2.18 Billion. 

Outlook

With Golden Dyke’s results rivaling those of Rising Sun, Southern Cross Gold appears to be defining one of Australia’s most promising gold-antimony systems. The ongoing drill campaign, coupled with favorable geopolitical tailwinds for critical minerals, keeps Sunday Creek firmly in the spotlight as a world-class discovery in the making.

“The dual character of bonanza intercepts nested within broader zones gives us significant mining optionality,” Hudson concluded. “Sunday Creek continues to demonstrate the potential to be a globally relevant gold-antimony district.”
