Southern Cross Gold Consolidated (SX2) Corporate Presentation summary

Project overview and objectives

• Sunday Creek is positioned as a significant global gold discovery with a focus on high-margin gold production and exceptional drilling hit rates.

• 167 drill holes totaling 70.7 km have been reported, with 55 intersections exceeding 100 AuEq g/t x m, and 70 vein sets wireframed in the main area.

• The drilling plan targets grade, volume, and scale, with five diamond rigs operating and plans to expand drilling by 60 km through Q3 2025.

• The project is fully funded with $22 million cash, 1,055 ha freehold land, and 100% ownership with no commercial royalties.

• Sunday Creek's maiden exploration target is 4.4–5.1 Mt at 7.2–9.7 g/t AuEq for 1.0–1.6 Moz AuEq, with significant upside as only 3% of the trend has been tested.

Geology, mineralization, and continuity

• The project is located in Victoria's Melbourne Zone, with gold-antimony mineralization hosted in subvertical vein arrays and dykes.

• Vein sets range from 0.5–10m wide, averaging 1.8–12.5 g/t Au and 0.1–5.2% Sb, with high-grade cores up to >1,000 g/t Au and >5% Sb.

• Structural geology and geostatistics show low coefficients of variation (CV), indicating strong grade continuity and reducing geological risk.

• High-grade gold is not nuggety, with repeatable lab results and visible gold in core, supporting reliable resource modeling.

• Paragenesis involves quartz-diorite dykes, folding, brecciation, and late faulting, creating complex but predictable mineralized domains.

Metallurgy and processing

• Preliminary metallurgical tests show non-refractory ore, with 82–84% native gold and simple gravity-flotation flowsheet.

• Gravity and flotation recoveries reach 93.3–97.6% for gold and 87.1–93.8% for antimony, with low to moderate arsenic levels.

• Optimization efforts are ongoing to maximize gold recovery and minimize arsenic in the antimony-gold concentrate.
