Southern Cross Gold Announces Drilling Results at Golden Dyke Demonstrate High-Grade Gold Mineralization and System Expansion

The October 23, 2025 news release announces drilling results from two holes, SDDSC177 and SDDSC182, at the Golden Dyke prospect of the Sunday Creek Project.

Key highlights from the release include: - SDDSC177: Intersected a very wide mineralized zone of 168 metres (m) grading 2.4 grams per tonne (g/t) gold (Au). Within this, a higher-grade zone returned 6.2 m at 16.0 g/t Au. - Record Antimony: Hole SDDSC177 also returned the third-highest antimony (Sb) assay in the project's history, with 0.2 m grading 52.3% Sb and 35.9 g/t Au. - SDDSC182: Intersected 1.5 m grading 19.5 g/t Au with a high antimony grade of 8.2% Sb. - System Expansion: The results confirm a 100 m vertical extension on one vein set and have discovered a new high-grade vein. - Operations Update: The company has completed 97,183 m of drilling in 217 holes, with nine rigs currently active and results from 37 holes pending.

The news is materially positive and continues the company's track record of delivering exceptional exploration results that build confidence in the scale and grade of the Sunday Creek project.

Reviewing the historical news provides critical context: - Corporate Transformation (Jan 2025): The year began with a significant corporate restructuring. The company (formerly Mawson Gold) spun out its uranium assets, consolidated its shares, changed its name, and completed the acquisition of the remaining interest in Southern Cross Gold Ltd. This created a simplified, pure-play vehicle focused 100% on the Sunday Creek project with listings on both the TSX and ASX. - Exploration Target Upgrade (Mar 2025): A major catalyst was the doubling of the exploration target to a range of 2.2 to 3.2 million ounces of gold equivalent (AuEq) at an increased grade of 8.3 to 10.6 g/t AuEq. This event significantly increased the perceived scale and quality of the project, setting a high bar for future exploration. - Game-Changing Financing (May 2025): The company closed a massive C$143 million private placement at C$4.50 per share. This transaction was transformative, fully funding an aggressive multi-year exploration and development program, including 207,000 m of drilling, a 1 km underground decline, and a Preliminary Economic Assessment (PEA). This removed all near-term financing risk and signaled strong institutional support. - Consistent High-Grade Results (Feb-Oct 2025): Throughout the year, the company released a steady flow of high-grade drill results from all key prospects (Christina, Rising Sun, Apollo, Golden Dyke), consistently expanding the mineralized footprint and confirming continuity. Highlights include 3.4 m @ 466 g/t Au (May), 3.9 m @ 124.6 g/t Au (June), and 0.5 m @ 342.2 g/t AuEq (October). The project's inventory of high-grade hits (>100 g/tm AuEq) has grown to 70. - De-risking Progress:* The company has advanced on multiple fronts, initiating permitting for an exploration tunnel, undertaking positive metallurgical work confirming high recoveries with conventional processing, and upgrading its US stock listing to the OTCQX for better visibility.

The October 23rd news fits perfectly into this established pattern of success. The wide 168 m intercept at Golden Dyke demonstrates potential for bulk tonnage, complementing the numerous high-grade, narrower veins that define the project. The record antimony intercept further enhances the project's strategic value, especially given China's export restrictions on the critical mineral. While not a standalone "game-changer" like the financing or target upgrade, these results are significant. They reinforce the geological model, expand the known mineralization, and confirm that the exploration program is effectively delineating a world-class system.

Southern Cross Gold Consolidated Ltd. is a Canadian and Australian dual-listed exploration company focused on its 100%-owned Sunday Creek Gold-Antimony Project in Victoria, Australia, a Tier-1 mining jurisdiction. The flagship project is an epizonal gold deposit characterized by a "Golden Ladder" structural model, where numerous high-grade, gold-bearing veins cross-cut a mineralized host structure. The project is notable for its dual-commodity nature, with antimony contributing significantly to its potential value, especially given its status as a critical mineral with a supply chain dominated by China.
