Southern Cross Gold Reinforces Continuity in Rising Sun Including 0.5 m @ 342.2 g/t AuEq (335.5 g/t Au, 2.8% Sb) Project Now Contains 70 Drill Intersections >100 g/t m AuEq

Executive Summary

• Southern Cross Gold reported high‑grade gold–antimony intersections from five diamond drill holes at the Rising Sun prospect, confirming lateral continuity of the RS15 vein and stacked vein architecture.
• Notable intercepts include 0.5 m @ 342 g/t AuEq (335 g/t Au, 2.8 % Sb) just 12 m from a previous 0.7 m @ 604 g/t AuEq, and an 18.0 m @ 3.7 g/t AuEq interval containing multiple higher‑grade cores.
• The results raise the project total to 70 intersections >100 g/t AuEq·m and 74 intersections 50–100 g/t AuEq·m, positioning Sunday Creek among the world’s highest‑grade gold projects and highlighting its strategic antimony resource.

Key Details

• Hole SDDSC169AW1 (Rising Sun)
• 0.5 m @ 342.2 g/t AuEq (335.5 g/t Au, 2.8 % Sb) at 615.7 m – lateral continuity with previous 0.7 m @ 604 g/t AuEq.
• 5.9 m @ 4.6 g/t AuEq (3.6 g/t Au, 0.4 % Sb) from 550.3 m, including 1.4 m @ 12.6 g/t AuEq.

• Multiple lower‑grade intervals confirming stacked vein sets over >160 m vertical extent.

• Hole SDDSC178W1 (Rising Sun)

• 18.0 m @ 3.7 g/t AuEq (1.6 g/t Au, 0.9 % Sb) from 574.8 m, with four higher‑grade zones:
  • 0.6 m @ 17.7 g/t AuEq (14.9 g/t Au, 1.2 % Sb)
  • 1.5 m @ 9.0 g/t AuEq (4.1 g/t Au, 2.1 % Sb)
  • 0.2 m @ 51.4 g/t AuEq (3.6 g/t Au, 20 % Sb)
  • 1.3 m @ 14.1 g/t AuEq (2.0 g/t Au, 5.1 % Sb)

• Record antimony assays >40 % Sb:

  • 0.13 m @ 43.8 % Sb, 3.15 g/t Au
  • 0.13 m @ 42.1 % Sb, 25.3 g/t Au (125.9 g/t AuEq)

• Project Milestone

• Cumulative high‑grade intersections now total 70 >100 g/t AuEq·m and 74 between 50–100 g/t AuEq·m across Sunday Creek.

• Technical Highlights

• Use of precise wedge technology to correct deviated parent holes, enabling targeted vein set interceptions.
• Drill program continues with 200,000 m planned through Q1 2027; results pending from 32 additional holes.
