Скачать или смотреть Southern Cross achieves significant metallurgical development at Sunday Creek Gold-Antimony project

Vancouver, Canada and Melbourne, Australia - Southern Cross Gold Consolidated Ltd ("SXGC", "SX2" or the "Company") (TSX:SXGC) (ASX:SX2) (OTCPK:MWSNF) (Frankfurt:MV3.F) is pleased to announce a significant metallurgical development at its Sunday Creek Gold-Antimony Project in Victoria.

Stage 2 test work has demonstrated successful selective flotation processing that produces a high-grade, low-arsenic antimony-gold concentrate from the upper antimony rich zones of the deposit, alongside excellent recovery of native gold.

Key Points

1. Significant Development: Selective Flotation Technology
Identified specialized collector chemistry that successfully separates antimony minerals from arsenic-bearing minerals, solving a key requirement while maintaining excellent gold recovery.

2. Triple Product Stream
Overall gold recovery of 92.3% to 95.6% across three product streams:
1. Gravity gold concentrate (37.3 – 51.4% recovered gold).
2. Antimony-gold concentrate (28.8 - 36.5% recovered gold): Antimony grades 48.2 – 53.1%, gold grades up to 93.2 g/t and arsenic grades 0.1% to 0.2% (well below 0.6% thresholds). Antimony recovery 83.2% to 92.7%.
3. Sulphide concentrate (15.5-18.0% recovered gold)

3. De-Risked For Further Development
A total of 144 samples from Apollo and Rising Sun prospects provide geometallurgical variation, with established processing conditions ready for scale-up through locked-cycle testing, pilot plant evaluation, and process plant design targeting Q1 2027.

Michael Hudson, President & CEO, states: "This significant metallurgical development significantly de-risks our Sunday Creek project and positions us to potentially deliver multiple high-value products to market. The combination of excellent overall native gold recovery with the ability to produce premium antimony concentrates validates our strategy and enhances the project's economic potential. The timing is particularly favorable given antimony's exemption from the recent US Executive Order on Reciprocal Tariffs and ongoing Chinese export restrictions on this critical metal."

Mr. Craig Brown, a Fellow of the Australasian Institute of Mining and Metallurgy and Metallurgical Consultant to Southern Cross Gold, commented: "This represents a significant advancement in our metallurgical understanding. We have demonstrated we can produce low-arsenic antimony concentrates while maintaining excellent gold recovery across multiple product streams. The selectivity we've achieved against arsenic in the antimony flotation stage will likely reduce reliance on blending strategies to produce acceptable concentrates."

About Southern Cross Gold Consolidated Ltd. (TSX:SXGC) (ASX:SX2)
Southern Cross Gold Consolidated Ltd. (TSX:SXGC, ASX:SX2) controls the Sunday Creek Gold-Antimony Project located 60 km north of Melbourne, Australia. Sunday Creek has emerged as one of the Western world's most significant gold and antimony discoveries, with exceptional drilling results including 66 intersections exceeding 100 g/t AuEq x m from just 84 km of drilling. The mineralization follows a "Golden Ladder" structure over 12 km of strike length, with confirmed continuity from surface to 1,100 m depth.
Sunday Creek’s strategic value is enhanced by its dual-metal profile, with antimony contributing 20% of the in-situ value alongside gold. This has gained increased significance following China's export restrictions on antimony, a critical metal for defense and semiconductor applications. Southern Cross’ inclusion in the US Defense Industrial Base Consortium (DIBC) and Australia's AUKUS-related legislative changes position it as a potential key Western antimony supplier. Importantly, Sunday Creek can be developed primarily based on gold economics, which reduces antimony-related risks while maintaining strategic supply potential.
Technical fundamentals further strengthen the investment case, with preliminary metallurgical work showing non-refractory mineralization suitable for conventional processing and gold recoveries of 93-98% through gravity and flotation.

With a strong cash position, over 1,000 Ha of strategic freehold land ownership, and a large 60 km drill program planned, SXGC is well-positioned to advance this globally significant gold-antimony discovery in a tier-one jurisdiction.
