Southern Cross Gold Hits New High at Sunday Creek

Key Highlights:

• Sunday Creek’s Mineral Resource Estimate (MRE) increased by 77% to 1.7Moz @ 4.1 g/t AuEq.
• 94% of the resource now sits within 500m from surface, enhancing near-term mineability.
• Company exploring 10km of untested strike beyond MRE footprint.
• SX2 shares up 3.6% to $5.605, market cap at $1.45B.
  
   

Southern Cross Gold Consolidated Ltd (ASX: SX2) has significantly upgraded its cornerstone Sunday Creek Project in Victoria, unveiling a 77% increase in its Mineral Resource Estimate (MRE) to 1.7 million ounces (Moz) of gold equivalent (AuEq). The announcement, released on Wednesday, 6 August 2025, underscores SX2’s aggressive and data-driven approach to unlocking one of Australia’s most promising high-grade gold systems.

The new MRE totals 13.5Mt @ 4.1 g/t AuEq, with 94% of the contained ounces located within 500 vertical metres of surface—highlighting the project’s near-surface potential and future economic viability.

A Clear Signal of Upside Potential

Southern Cross Gold Managing Director Michael Hudson described the resource update as a “clear demonstration” of the company’s growth trajectory:

“In just over a year, we’ve increased the resource by 77%, with more to come. The shallow nature of the mineralisation presents a compelling case for future development, and we’ve only just scratched the surface—literally,” said Hudson.

The updated MRE was defined using 69 drill holes across 17 diamond drill fans and covers only 10% of the 11km strike at Sunday Creek. The remaining 90% remains largely unexplored, which Hudson believes positions the project as “one of the most prospective near-term development assets in Australia.”

Grade, Scale, and Accessibility

The updated estimate includes:

• 1.66Moz gold equivalent within 500 vertical metres
• 1.48Moz AuEq in the Inferred category
• 0.18Moz AuEq in the Indicated category
  
   

The resource also includes co-product antimony, an increasingly critical metal due to its use in military applications, semiconductors, and green energy storage. Southern Cross continues to report exceptional grades of both gold and antimony in its diamond drilling program, with high-grade shoots remaining open at depth.

Antimony: A Strategic Edge

The dual commodity focus of gold and antimony is gaining investor attention. Antimony has been designated as a critical mineral by both the U.S. and Australian governments.

According to industry forecasts, the global antimony market is poised to grow from $2.5 billion in 2024 to $4.1 billion by 2034, driven by rising demand in EV batteries, flame retardants, and defense technologies. Sunday Creek’s high-grade antimony component, therefore, positions SX2 strategically amid shifting supply chain dynamics.

High-Impact Exploration Ahead

Southern Cross Gold remains focused on aggressive step-out drilling. The company is mobilizing additional rigs to test over 10km of untested strike that remains outside the current MRE. This could materially expand the resource base and set the stage for broader development discussions.

“With only a tenth of the system drilled, we believe we are in the early stages of unlocking a major mineralized system,” Hudson added.

Southern Cross is also working toward scoping studies and potential development scenarios. The next phase of exploration will target both depth and strike extensions, while regional exploration work will assess the potential of similar parallel structures in the broader tenement area.

Market Reaction and Outlook

SX2 shares rose 3.6% in early trading Wednesday, reaching $5.605. The company’s 12-month return now stands at +47.5%, reflecting market confidence in the asset’s scale and management’s execution. With a market capitalization of $1.45 billion, Southern Cross has become one of the most closely watched gold explorers on the ASX.

The broader market sentiment on gold remains positive. Spot gold prices are trading around $3,500/oz, up 30% year-to-date, and projected to hit $4,000/oz by mid-2026, according to JPMorgan Research. This strong macro backdrop provides additional tailwinds for SX2’s valuation.

With a significantly expanded resource, high-grade intercepts, and a massive undrilled footprint, Southern Cross Gold Consolidated is emerging as a standout explorer in Australia’s gold and critical minerals space. The company’s blend of geological scale, operational momentum, and strategic commodity focus has it well-positioned for sustained market interest.

As further drill results roll in and development studies take shape, Sunday Creek is increasingly looking like a cornerstone asset—not just for SX2, but for the broader Australian gold sector.
