Southern Cross Gold drills 1,466 g/t Au over 0.3 m at Rising Sun Deep

Vancouver, British Columbia and Melbourne, Australia--(Newsfile Corp. - August 25, 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, comprising the deepest west-to-east drill holes under Rising Sun (Figures 1 to 6). Four deep holes, including one wedge (SDDSC230W1), tested Rising Sun at depth.

Four High Level Takeaways:

Deepest drilling beneath Rising Sun returns very high grades. SDDSC230 intersected 0.3 m @ 1,466.7 g/t AuEq (1,466.4 g/t Au, 0.1% Sb) from 886.7 m, hosting an individual assay of 0.1 m @ 4,500 g/t Au , the fourth-highest single gold assay returned at Sunday Creek to date. The composite ranks as the 12th best composite intersection drilled at the project. SDDSC230 returned four further composites in the same intersection, headlined by 1.3 m @ 120.7 g/t AuEq from 987.1 m hosting individual assays of 428.0 g/t Au and 293.0 g/t Au, together with 4.3 m @ 9.0 g/t AuEq from 858.6 m, 1.0 m @ 33.0 g/t AuEq from 899.1 m and 0.6 m @ 52.2 g/t AuEq from 906.9 m.

High-grade mineralization keeps growing as drilling steps out. The five holes added three composite intersections exceeding 100 g/t Au, four between 50 and 100 g/t Au and eight individual gold assays above 50 g/t Au, lifting Sunday Creek to 96 composite intersections exceeding 100 g/t Au . Grade tenor continues to improve with depth at Rising Sun. Four of the eight individual very high-grade gold assays exceed 100 g/t Au and two exceed 400 g/t Au.

Grade continuity confirmed down-plunge and at depth. SDDSC230’s high-grade intersection lines up with mineralization previously reported 166 m up-dip in SDDSC144 (3.6 m @ 118.0 g/t AuEq), confirming continuity of the RS19 vein set, while SDDSC231, the deepest east-to-west step-out drilled to
