First deep holes beneath the historic Redcastle Goldfield confirm high-grade gold-antimony mineralisation extending more than 250 metres vertically.
Southern Cross Gold Consolidated Ltd (ASX:SX2) has reported results from its first deep drilling campaign beneath the historic Redcastle Goldfield in Victoria, with high-grade gold intersections supporting the continuation of a Costerfield-style gold-antimony mineralised system at depth.
The results come from two drill holes at the company’s wholly owned Redcastle Project, located about 64 kilometres north-northwest of the Sunday Creek project. Drill hole SDDRE016 intersected visible gold and multiple high-grade gold intervals over more than 250 metres of vertical extent.
The standout drill results include:
- 26.2 g/t Au over 0.14 metres from 112.98 metres
- 15.4 g/t Au over 0.22 metres from 321.84 metres
- 5.0 g/t Au with 0.33% Sb over 0.10 metres from 294.11 metres
The company said SDDRE016 returned eight separate high-grade gold intervals, providing evidence that the high-grade mineralisation historically mined near surface continues below the water table. Southern Cross Gold also noted that the interpreted true widths of the reported mineralised intervals are approximately 70% to 85% of the sampled thickness.
Beyond the initial drilling success, the company highlighted the broader exploration potential at Redcastle. The project hosts 14 individual reefs across a 900-metre-wide corridor and more than 17 kilometres of historic workings, with much of the district remaining largely untested below approximately 50 metres depth.
The results form part of Southern Cross Gold’s broader Victorian exploration program, where 11 drill rigs are operating across the Sunday Creek district. Two rigs are focused on regional targets outside the core Sunday Creek area as the company progresses its planned 200,000-metre drilling campaign through to the first quarter of 2027.

These are the first deep holes ever drilled beneath the Laura prospect at Redcastle, and they have done exactly what we hoped. We have intersected high-grade gold, visible gold and antimony in the same Costerfield-style vein architecture that has made this corner of Victoria one of the highest-grade gold endowments on earth.
Redcastle sits just 7 km along strike from Costerfield, on a parallel structure, with 14 reefs over a 900 m wide corridor and 17 km of historic workings that have barely been scratched below the water table. SDDRE016 tells us the system has real depth potential, and it is only the beginning of a sustained regional campaign.
