Terra Balcanica Completes 1200 m of Phase III Drilling at Silver-Antimony Targets in Bosnia and Herzegovina

Executive Summary

• Terra Balcanica Resources Corp. completed the first stage of its 2,100 m Phase III drilling program at the Brezani and Chumavichi targets in the Viogor‑Zanik project, Bosnia & Herzegovina.
• Drillholes BRE25001/​BRE25001A intersected a ~50–60 m interval of retrograde altered skarn hosting previously reported 0.61 g/t AuEq over 88 m and new structural zones with intermediate sulphidation epithermal mineralization.
• Drillholes CMV25001‑CMV25004 encountered multiple shallow massive sulphide and quartz‑sulphide veins in the Chumavichi structure, extending known high‑grade Ag‑Sb‑Zn‑Pb‑Au mineralization; assays are pending.

Key Details

• Drilling Scope: ~1,200 m of oriented diamond core completed across Brezani and Chumavichi targets.
• BRE25001 & BRE25001A: Located 72 m NE of discovery hole BREDD002 (19.6 m @ 436 g/t AgEq). Both holes intersected a ~50–60 m retrograde altered skarn interval and several structural zones with intermediate‑sulphidation epithermal mineralization.
• CMV25001‑CMV25004: All four holes intercepted shallow, massive sulphide and quartz‑sulphide vein‑hosted mineralization in the hanging and footwall of the SW‑dipping Chumavichi structure, all above 80 m depth.
• Mineralogy: Polymetallic (Ag‑Sb‑Zn‑Pb‑Au) confirmed by sulphide observations and pXRF; key intervals have been sampled for assay.
• Assay Status: Lithogeochemical assays pending; results will be released once laboratory data is complete.
• Core Recovery: >94 % average core recovery achieved despite challenging ground conditions.
• Future Plans: Additional drillholes to test the main Ag‑Sb‑Zn‑As‑Bi soil anomaly at Brezani and step‑out drilling at Chumavichi are planned for January 2026, contingent on assay release.
• Qualified Person: Dr. Aleksandar Miškovic, P.Geo., reviewed and validated the information per NI 43‑101 standards.

“We are pleased to have completed over a half of the planned meterage despite numerous setback and technical challenges… The Terra exploration hypothesis about the extension of the base‑metal dominated, epithermal mineralization … continues to be refined in the light of new 3D data.” – Dr. Aleksandar Miškovic, President & CEO

Materiality Assessment: Non‑Material – Positive (operational update with no immediate financial impact; provides positive exploration insight).
