Southern Cross Gold Consolidated (ASX:SX2) announced a major exploration milestone at its Sunday Creek Project, drilling the deepest hole in the project's history.
The drill hole, SDDSC194W1, intersected high-grade gold mineralisation approximately 1,236m vertically below the surface, confirming that the mineralising system remains open and active at extreme depths.
The discovery marks a breakthrough, as the gold hit occurred 460m below previously intersected mineralisation at the Golden Dyke prospect.
The results surpassed internal exploration targets by roughly 490m, materially expanding the known vertical scale of the deposit.
Geological analysis revealed a wide zone of 66m of dyke and altered sediment, including a high-grade interval of 0.9m at 5.4 g/t Au eq.
Technical teams highlighted that the fluid chemistry at these depths remains highly favourable.
Arsenic-to-antimony ratios observed in the deep core samples are consistent with expected geochemical zonation, providing the company with strong "vectoring confidence".
This suggests the system retains the necessary thermal and chemical signature to host significant gold at depth.
Furthermore, the south-to-north orientation of this control programme has established a robust geometric framework for future exploration.
This allows Southern Cross Gold to optimise future intercepts by drilling at high angles.
At the time of reporting, Southern Cross Gold Consolidated’s share price was $9.76.
