Southern Cross Gold hits 26.2 g/t Au in first deep drilling at Redcastle

Vancouver, British Columbia and Melbourne, Australia--(Newsfile Corp. - July 15, 2026) - Southern Cross Gold Consolidated Ltd  (TSX: SXGC) (ASX: SX2) (OTCQX: SXGCF) (FSE: MV3) ("SXGC", "SX2" or the "Company")  announces results from two drill holes from the 100%-owned Redcastle Project in Victoria (Figures 1 to 7). Redcastle is located 64 km to the NNW of the Company's Sunday Creek project (Figure 7). Best results included 26.2 g/t Au over 0.14 m from 112.98 m and 15.4 g/t Au over 0.22 m from 321.84 m in drill hole SDDRE016 at the Laura prospect, two of eight individual high-grade gold intervals from that hole, which confirmed Costerfield-style gold-antimony mineralization including visible gold over more than 250 m of vertical extent.

The true thickness of the mineralized intervals is interpreted to be approximately 70% to 85% of the sampled thickness for all reported holes. Four High Level Takeaways: First deep test confirms the system. SDDRE016 is among the first holes to test the Laura prospect below the historic workings and water table, intersecting gold and antimony bearing vein mineralisation over more than 250 m of vertical extent, with visible gold in subvertical extensional veins reminiscent of Costerfield-style mineralization.

High grades at depth. Eight separate high-grade gold intervals were returned from SDDRE016, headlined by 26.2 g/t Au over 0.14 m from 112.98 m, 15.4 g/t Au over 0.22 m from 321.84 m and 5.0 g/t Au with 0.33% Sb over 0.10 m from 294.11 m, demonstrating that the high grades historically mined at surface continue at depth. A district-scale opportunity.

Redcastle hosts 14 individual reefs across a 900 m cross-strike corridor and combined historic workings over 17 km of strike, the great majority of which has never been drill tested below approximately 50 m depth, providing a strong pipeline of targets along strike from Cost
