Southern Cross Gold Extends High Grades to East and to Depth at Apollo East

Executive Summary

• Hole SDDSC170A intersected an exceptional high‑grade core of 0.2 m @ 504 g/t Au (41.8 g/t AuEq) and a broader 10.8 m @ 12.6 g/t Au interval, the highest gold grades recorded at Apollo East.
• Mineralization was extended 75 m eastward and 115 m down‑dip beyond previous limits, expanding the Apollo East target area.
• A record antimony grade of 33.7 % Sb (9.9 g/t Au) was intersected, underscoring Sunday Creek’s strategic antimony potential.
• Multiple >100 g/t Au intersections were returned at depths >1,000 m, confirming continuity and improvement of the system with depth.

Key Details

• High‑grade core (SDDSC170A): 0.2 m @ 504 g/t Au (41.8 g/t AuEq) from 672.1 m; 3.1 m @ 22.7 g/t Au, 8.0 % Sb from 690.5 m.
• Broad halo: 10.8 m @ 12.6 g/t Au (true width ≈ 7.7 m) from 669.7 m surrounding the high‑grade core.
• Antimony peak: 0.3 m @ 33.7 % Sb, 9.9 g/t Au from 691.8 m – highest Sb grade at Apollo East.
• Depth continuity: +100 g/t Au hits at 948.7 m (107 g/t Au) and 1,005.4 m (115 g/t Au). Additional intervals: 2.9 m @ 11.3 g/t Au from 1,004.4 m; 0.9 m @ 33.8 g/t Au from 948.4 m.
• Extension: Mineralization now extends 75 m east and 115 m down‑dip beyond prior drilling limits.
• Other holes: SDDSC163A returned a notable 0.1 m @ 58.4 g/t Au (59.7 g/t AuEq) at 980.8 m; peripheral lower‑grade intersections improve geological understanding of the Apollo system.
• Drilling program: 200,000 m total planned through Q1 2027 with nine rigs operating; current focus on step‑out drilling eastward, deep follow‑up of >100 g/t Au zones, and infill drilling for resource estimation.
• Metallurgical update: Expanded testing confirms high gold (93–98 %) and antimony recoveries (83–93 %) with antimony concentrate (~50 % Sb, <0.2 % As) suitable for smelter market; further pilot‑plant work slated for 2027.

Notable Quotes

• “SDDSC170A has delivered exactly what we hoped to find – high‑grade extensions at depth and along the eastern margins… The 75 m eastward extension of Apollo East takes us into untested ground, while the 504 g/t gold and 33.7 % antimony confirm the system maintains exceptional grades as we push deeper.” – Michael Hudson, President & CEO
