Southern Cross Gold Consolidated (SX2) investor relations material

Project overview and strategic positioning

• Sunday Creek is a high-grade, pre-production gold project with significant antimony content, located 60 km north of Melbourne and 100% owned, with no commercial royalties.

• The project sits within the same geological corridor as Fosterville and Costerfield, both renowned for high-grade gold and antimony production.

• Only 10% of the 11 km mineralized trend has been tested, with mineralization open at depth and along strike, indicating substantial exploration upside.

• Victoria is highlighted as the best jurisdiction in Australia for mine permitting, with Sunday Creek receiving the fastest exploration tunnel approval on record.

• The project is fully funded with A$123M in cash and a total 2026 program budget of A$115M, supporting aggressive drilling and development.

Exploration results and resource potential

• March 2025 exploration target: 2.2–3.2 Moz AuEq at 8.3–10.6 g/t, based on 8.1–9.6 Mt, with both gold and antimony contributing to value.

• 85 drill intercepts above 100 g/t Au have been reported from 119.6 km drilled, with standout results including 2.7m @ 891.7 g/t Au and 0.5m @ 2,541.9 g/t Au.

• Grades improve at depth, especially below 600–700 m, with mineralization remaining open and continuity supported by structural and geostatistical data.

• The project features multiple prospects (Rising Sun, Apollo, Golden Dyke) and a robust vein system with high-grade gold and antimony zones.

• Metallurgical studies show non-refractory ore with 92–96% gold recovery using a simple gravity-flotation process.

Strategic antimony advantage

• Antimony is classified as a defence-critical mineral, with 82% of global supply controlled by China and Russia, making Western sources highly strategic.

• Sunday Creek has 104 intercepts exceeding 10% Sb, with the top hit at 56.5% Sb over 0.3m, and is positioned to become a key Western supplier.

• Australia has prioritized antimony in its A$1.2B Critical Minerals Strategic Reserve, and Victoria has launched Advancing Antimony Grants.
