Southern Cross Gold Consolidated (SX2) Corporate Presentation summary

Project overview and strategic positioning

• Sunday Creek is a rapidly growing, high-margin gold-antimony greenfield discovery in Victoria, Australia, recognized as one of the few large, independently owned global projects of its kind.

• The project is fully owned, with 1,055 ha of freehold land, no commercial royalties, and is well-funded with A$18 million in cash.

• Located in a Tier 1 jurisdiction, Victoria is supportive of mining, with recent improvements in permitting and two major mines approved in December 2024.

• The company is actively de-risking the project through pre-development activities, including engineering, feasibility, and environmental studies.

• Sunday Creek is positioned to benefit from critical minerals initiatives and global demand for antimony, a key strategic metal.

Exploration results and resource potential

• 157 drill holes totaling 71.4 km have been reported, with 56 intersections exceeding 100 AuEq g/t x m, indicating exceptional grades and continuity.

• The maiden exploration target (Jan 2024) 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 12 km trend has been tested.

• Drilling has identified 70 vein sets within the main area, with high-grade intersections such as 1.0 m @ 2,319 g/t AuEq and 20.0 m @ 63.7 g/t AuEq.

• Grade continuity is supported by low coefficients of variation, repeatable assays, and robust geological modeling.

• The project’s mineralization is open at depth and along strike, with ongoing drilling and resource expansion planned.

Metallurgy and processing

• Preliminary metallurgical tests show the ore is non-refractory, with 82–84% native gold and simple gravity-flotation flowsheet yielding 93–98% gold recovery.

• Antimony is a significant by-product, with flotation concentrates grading 32–52% Sb and recoveries up to 94%.

• Further metallurgical optimization is underway to maximize gold recovery and minimize arsenic in concentrates.
