Southern Cross Gold Drills 0.6 m @ 972 g/t Gold in Apollo and Drills Easternmost Mineralization

Vancouver, British Columbia and Melbourne, Australia--(Newsfile Corp. - September 2, 2026) - Southern Cross Gold Consolidated Ltd  (TSX: SXGC) (ASX: SX2) (OTCQX: SXGCF) (FSE: MV3) ("SXGC", "SX2" or the "Company") announces results from five drill holes at the 100%-owned Sunday Creek Gold-Antimony Project in Victoria, showing the increase in grade at depth in Apollo and extended Sunday Creek to its furthest eastern point to date with high grades in up-dip areas of Apollo East (Figures 2 to 6). SDDSC222W1 returned the headline result, 0.6 m @ 993.2 g/t AuEq (972.0 g/t Au, 8.9% Sb) from 808.5 m, the 9 th best composite intersection drilled at Sunday Creek, 620 m below surface. SDDSC227 returned the shallowest high-grade intersection drilled in Apollo East , 5.1 m @ 27.2 g/t AuEq including 2.6 m @ 51.1 g/t AuEq from 260.9 m and only 144 m below surface, and the most easterly and shallowest drill intersection on the project, along with an antimony assay of 32.5% Sb. Five individual assays in this release exceed 50 g/t Au, ranging from 97.6 g/t to 972.0 g/t. Four High Level Takeaways:  Grades continue to strengthen at depth in Apollo . SDDSC222W1 returned 0.6 m @ 993.2 g/t AuEq (972.0 g/t Au, 8.9% Sb) from 808.5 m, extending the A130 vein set 40 m below its known vertical depth extent. The intersection ranks as the 9th best intersection drilled at Sunday Creek to date, returned approximately 620 m below surface.  High-grade mineralization now extends much closer to surface in Apollo East . SDDSC223 and SDDSC227 both extended the Apollo East vein sets up-dip, with SDDSC223 returning 97.6 g/t Au , 144 m below surface, and SDDSC227 delivering 5.1 m @ 27.2 g/t AuEq (18.4 g/t Au, 3.7% Sb) from 260.9 m, including individual assays of 186.0 g/t Au and 116.0 g/t Au . Both high-grade assays sit inside a 2.6 m @ 51.1 g/t AuEq interval.  The Apollo East corridor keeps expanding along strike to the east. SDDSC222 alone intersected seven separate Apollo East vein sets across prospective terrain and combined with the up-dip results from SDDSC223 and SDDSC227, Apollo East is now defined across 140 m of horizontal strike, reinforcing that this is a broad, multi-vein system. Apollo East is one of five mineralized areas along 1,550 m of drill-defined host strike, of which approximately 650 m has been intensively drill tested. SDDSC227 also returned the easternmost significant intersection drilled at the main Sunday Creek Project to date , approximately 110 m below surface and directly beneath mineralization identified in the MTSC001 trench completed in 2021, which it likely extends down-dip.  Antimony grades strengthen alongside the gold in shallow Apollo East. SDDSC227 returned 32.5% Sb , one of five individual assays above 15% Sb reported for Apollo East. Together, they show Apollo East carries high-grade gold and meaningful antimony grades into shallow areas. The 186.0 g/t Au assay carried 5.2% Sb, and SDDSC222 returned three individual assays above 15% Sb at depth, showing antimony tenor is carried through the full vertical extent of the system.  Michael Hudson, President & CEO, states : "This release does two things at once. SDDSC222 and its wedge SDDSC222W1 pushed Apollo down-dip, returning 972 g/t gold over 0.6 m at 620 metres vertical depth, our 9 th best intersection at Sunday Creek. SDDSC223 and SDDSC227 extended Apollo East to its shallowest and easternmost extensions . Grades keep improving with depth at Sunday Creek rather than tailing off, but they are not absent at surface either. "SDDSC227 makes the point better than any hole here: 32.5% antimony, alongside individual gold assays of 186.0 g/t and 116.0 g/t, all within 144 m of surface . SDDSC227 returned 5.1 m @ 27.2 g/t gold equivalent including 2.6 m @ 51.1 g/t and also delivered the easternmost significant intersection drilled at Sunday Creek to date, 110 m below mineralization we trenched at MTSC001 back in 2021. Apollo East is open to the east and we intend to keep pushing it in that direction. "We are growing Apollo and Apollo East in both directions at once, and with eleven rigs turning, results pending from 72 holes and our 200,000 m program running through to Q1 2027, we expect to keep delivering." For Those Who Like the Details - Highlights:  SDDSC222 intersected a 118 m stacked mineralized zone between 533.4 m and 651.4 m containing both gold and antimony-dominant veins: The full 118 m zone averages 1.6 g/t AuEq (1.0 g/t Au, 0.26% Sb), with a higher-grade core of 39.3 m @ 3.3 g/t AuEq (2.3 g/t Au, 0.41% Sb) from 597.3 m. The hole intersected seven Apollo East vein sets and extended several of them 40 m to 70 m up-dip, and returned three individual assays above 15% Sb, peaking at 26.2% Sb with 5.2 g/t Au over 0.1 m from 619.9 m. Highlights include:  1.0 m @ 17.7 g/t AuEq (0.4 g/t Au, 7.2% Sb) from 575.4 m, including:  0.4 m @ 43.1 g/t AuEq (0.8 g/t Au, 17.7% Sb) from 575.4 m  5.7 m @ 7.5
